Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 55% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of mid cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Mid cap companies are companies with market capitalizations equal to those within the universe of the Russell Midcap^® Index securities at the time of purchase. As of the last reconstitution of the Russell Midcap Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals, quantitative screening and proprietary fundamental analysis. The Fund focuses on mid-sized companies with increasing market share, strong earnings prospects and sustainable free cash flows as compared to their competitors. The Fund also looks for dominant franchises with predictable business models deemed capable of achieving sustained growth and undervalued companies with the potential to grow their intrinsic value per share.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Russell Midcap^® Index and the Lipper Mid-Cap Core Funds Index, an index based on the total returns of certain mutual funds within mid cap funds category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares is based on the performance of the Select Class Shares prior to their inception on 11/2/09. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments of large and mid capitalization companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund generally defines large capitalization companies as those with a market capitalization over $10 billion at the time of purchase, and mid capitalization companies as those with market capitalization between $1 billion and $10 billion, at the time of purchase.

In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 1000 Value Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative out performance. In identifying high quality securities, the adviser looks for profitable companies with sustainable earnings and disciplined management. In identifying securities that have strong momentum, the adviser looks for securities which have prices and/or earnings that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Mid Cap Company Risk. Because the Fund may invest in large- and mid-capitalization companies, the Fund’s risks increase as it invests more heavily in mid-capitalization companies. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 1000^® Value Index and the Lipper Large-Cap Value Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares in the table is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund’s adviser applies an active equity management style focused on identifying attractively valued stocks given their growth potential over a long-term time horizon. The securities held by the Fund will predominantly be of companies with market capitalizations similar to those within the universe of S&P 500/Citigroup Value Index stocks.

While common stocks are the Fund’s primary investment, the Fund may also invest significantly in real estate investment trusts (REITs) and depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser will emphasize companies which are leaders within their sectors. The Fund will also emphasize companies with attractive valuations and low price-to-cash flows ratios. The Fund will seek to earn income by investing in companies that display, or have the potential for displaying, level or rising dividends. The adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals, quantitative screening and proprietary fundamental analysis. The adviser looks for undervalued companies with durable franchises, strong management and the ability to grow their intrinsic value per share.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Strategy Risk. An undervalued stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. To the extent that the Fund invests in depositary receipts, such investments are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the S&P 500/Citigroup Value Index, and the Lipper Large-Cap Value Funds Index and Lipper Large-Cap Core Funds Index, both of which are indexes based on the total returns of certain large cap mutual funds as determined by Lipper. Unlike the other index, the Lipper indexes include the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance figures would have been lower.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest primarily in long and short positions of equity securities issued by large capitalization companies and intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value).

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of securities of publicly traded large capitalization securities. Large capitalization securities are those equity securities of companies with market capitalizations similar to those within the universe of the S&P 500 Index at the time of purchase. Equity securities in which the Fund invests significantly are common stocks of U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets. In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets, the Fund expects the value of the short positions will decline faster than the long positions. As a result, in declining markets, the Fund expects that it will be able to close out its short positions at a lower cost resulting in additional gain to the Fund.

The Fund intends to invest in a variety of equity securities and, ordinarily, no single equity exposure is expected to make up more than 5% of the gross long exposure except that companies with large weights in the Fund’s benchmark may be held as overweights in the Fund, resulting in positions of greater than 5% in those securities.

Investment Process: The adviser’s investment process is based upon a quantitative multi-factor model with a qualitative over- lay. The adviser uses its quantitative multi-factor model to collect quantitative and fundamental investment data designed to evaluate the relative attractiveness of stocks. The quantitative multi-factor model puts an emphasis on valuation drivers and growth drivers. The valuation drivers include factors such as discounted cash flows and price-to-book values and the growth drivers include factors such as revisions of earning estimates and earnings growth rates. The adviser generally buys long positions in securities that are ranked favorably by its quantitative multi-factor model and sells short securities that are ranked unfavorably. The adviser generally sells long positions in securities that are no longer favorably ranked and covers short positions in securities that are no longer unfavorably ranked. The adviser may also buy, sell, sell short and cover short positions in securities that it views as similarly ranked.

In constructing the Fund’s portfolio, the adviser employs a bottom up stock selection process in combination with its qualitative overlay to determine the weights of each model factor and the risk posture of the Fund. The adviser may invest across different industries and sectors targeting both value-and growth-oriented domestic companies. Viewed sector by sector, the Fund’s net weightings of equity securities will generally be similar to those of its benchmark index, the S&P 500 Index. The adviser uses its qualitative analysis to over and underweight sectors, industries and stocks versus the S&P 500 Index. Sector and industry positioning is used to enhance returns and for risk management.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector swings or other risk factors.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of mid cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Mid cap companies are companies with market capitalizations equal to those within the universe of the Russell Midcap Index at the time of purchase. As of the last reconstitution of the Russell Midcap Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a fundamental bottom-up investment process. The adviser seeks to invest in companies with leading competitive advantages, durable business models and sustainable free cash flow generation with management committed to increasing shareholder value. It also looks to invest in securities that are trading at a discount to their intrinsic value.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit- worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal period (October 3, 2011 through June 30, 2012), the Fund’s portfolio turnover rate (including short sales) was 80% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

In seeking to meet its objectives, the Fund will 1) take long and short positions in equity securities of U.S. large-cap companies in an effort to increase the Fund’s return relative to the S&P 500 Index, the Fund’s benchmark, and to traditional large-cap strategies which do not have the ability to sell stock short, while keeping the Fund’s net exposure to the equity market at a level similar to a traditional “long-only” strategy, and 2) manage both its long and short positions in a manner that seeks to maximize after-tax return. In combining these approaches, the Fund not only endeavors to outperform traditional “long-only” strategies, but also “long-only” tax aware strategies.

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of equity securities of large capitalization U.S. companies. Large capitalization companies are companies with market capitalizations of at least $4 billion at the time of purchase. “Assets” means net assets, plus the amount of borrowings for investment purposes. These equity securities will be selected from the universe of publicly traded securities with characteristics similar to those of large capitalization companies in the S&P 500 Index. In implementing its strategies, the Fund invests primarily in common stocks of U.S. companies, but may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index, as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping its net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However, the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

In implementing its secondary objective of maximizing after-tax return, the Fund employs a number of tax aware strategies and seeks to minimize shareholder’s tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gain available for distribution. The Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gains, holding securities long enough to avoid short-term capital gains, endeavoring to sell securities with a high cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. Because the Fund also has the ability to short securities, it can implement additional tax-aware strategies that have the potential to increase the after-tax benefits to shareholders. These include the ability to realize additional capital losses regardless of market conditions and to net dividend expenses associated with the Fund’s short positions against the Fund’s dividend income. If the Fund distributes net investment income, the Fund will seek to maximize its ability to distribute dividends designated as qualified dividend income (which is taxed at a lower long-term capital gains rate rather than at the higher tax rate for ordinary income (for non-corporate shareholders)). However, it is possible that a portion of the Fund’s distributions will be taxed as ordinary income.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• high perceived potential reward compared to perceived potential risk
• possible temporary mispricings caused by apparent market overreactions

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income.

Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities held long (or appreciating prices of securities held short), or when the securities the Fund wishes to or is required to sell are illiquid.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 110% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments of large and mid capitalization companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund generally defines large capitalization companies as those with a market capitalization over $10 billion at the time of purchase, and mid capitalization companies as those with market capitalization between $1 billion and $10 billion, at the time of purchase.

In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 1000 Growth Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative out performance. In identifying high quality securities, the adviser looks for profitable companies with sustainable earnings and disciplined management. In identifying securities that have strong momentum, the adviser looks for securities which have prices and/or earnings that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Mid Cap Company Risk. Because the Fund may invest in large and mid capitalization companies, the Fund’s risks increase as it invests more heavily in mid cap companies. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 1000^® Growth Index and the Lipper Large-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares in the table is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000^® Index stocks at the time of purchase. As of the last reconstitution of the Russell 2000 Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In implementing its main strategies, the Fund invests primarily in common stocks.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a fundamental bottom-up investment process. The adviser seeks to invest in companies with leading competitive advantages, predictable and durable business models and sustainable free cash flow generation with management committed to increasing intrinsic value.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13, and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

SELECT CLASS SHARES	212	1,060	1,923	4,151

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 75% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will invest in equity securities of large capitalization, U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large capitalization companies are companies with market capitalizations of at least $4 billion at the time of purchase. In implementing its strategy, the Fund invests primarily in common stocks, real estate investment trusts (REITs) and depositary receipts. The adviser also generally is sector neutral relative to the S&P 500 Index and emphasizes stock selection as the primary means of generating returns.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies that do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities and derivatives on those securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• impact on the overall risk of the portfolio relative to the benchmark
• high potential reward compared to potential risk and
• temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. To the extent the Fund invests in depositary receipts, such investments are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund, will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 57% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments across all market capitalizations. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund will generally invest in companies with a market capitalization of $500 million or greater at the time of purchase. In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 3000 Index that the adviser believes are undervalued and/or have strong momentum. In identifying securities that have strong momentum, the adviser looks for securities which have prices that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Smaller Cap Company Risk. Although the Fund may invest in equity investments of companies across all market capitalizations, the Fund’s risks increase as it invests in smaller companies (mid cap and small cap companies). Smaller companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty).

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 3000^® Index and the Lipper Multi-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The Fund’s performance prior to 4/10/06 may be less pertinent for investors considering whether to purchase shares of the Fund because of changes made to the Fund’s investment policies beginning at that time. The performance of the Class A and Class C Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 83% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its strategy, the Fund primarily invests in common stocks of large- and medium-capitalization U.S. companies, but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts.

Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund focuses on those equity securities that it considers most undervalued and seeks to outperform the S&P 500 through superior stock selection. By emphasizing undervalued equity securities, the Fund seeks to produce returns that exceed those of the S&P 500 Index. At the same time, by controlling the sector weightings of the Fund so they can differ only moderately from the sector weightings of the S&P 500 Index, the Fund seeks to limit its volatility to that of the overall market, as represented by this index.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as undervalued and considers selling them when they appear to be overvalued. Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price
• high potential reward compared to potential risk
• temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. The securities of mid cap companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Strategy Risk. An undervalued stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years.

CLASS C SHARES	201	621	1,068	2,306
SELECT CLASS SHARES	112	375	659	1,467

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000^® Growth Index and/or with market capitalizations of less than $3.5 billion at the time of purchase. As of the date of the last reconstitution of the Russell 2000 Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In implementing its main strategies, the Fund invests primarily in common stocks.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the Fund’s adviser seeks to outperform the Fund’s benchmark while maintaining a moderate risk profile. The adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. Growth companies purchased for the Fund include those with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Small Cap Company Risk. Investments in small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 95% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments of large and mid capitalization U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund generally defines large capitalization companies as those with a market capitalization over $10 billion at the time of purchase, and mid capitalization companies as those with market capitalization between $1 billion and $10 billion at the time of purchase.

In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 1000 Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative out performance. In identifying high quality securities, the adviser looks for profitable companies with sustainable earnings and disciplined management. In identifying securities that have strong momentum, the adviser looks for securities which have prices and/or earnings that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Because the Fund may invest in large and mid capitalization companies, the Fund’s risks increase as it invests more heavily in mid capitalization companies. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 1000^® Index and the Lipper Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares in the table is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 99% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests in a focused portfolio of equity securities of large capitalization companies. Large cap companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. Typically, the Fund invests in common stocks of companies with a history of above-average growth or companies expected to enter periods of above-average growth. Although the Fund will invest primarily in equity securities of U.S. companies, it may invest up to 20% of its total assets in foreign securities, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund is non-diversified.

Investment Process: The Fund’s adviser will utilize a combination of qualitative analysis and quantitative metrics in order to seek to achieve target returns which are higher than the Fund’s benchmark while attempting to maintain a moderate risk profile. In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. The adviser looks for companies with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may also trade at higher multiples of current earnings, compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past four calendar years. The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the Russell 1000^® Growth Index and the Lipper Large-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Subsequent to the inception of the Fund on 11/30/07 until 8/6/10, the Fund did not experience any shareholder purchase and sale activity. If such shareholder activity had occurred, the Fund’s performance may have been impacted. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

In seeking to meet its objectives, the Fund will 1) take long and short positions in equity securities of U.S. large-cap companies in an effort to increase the Fund’s return relative to the S&P 500 Index, the Fund’s benchmark, and to traditional large-cap strategies which do not have the ability to sell stock short, while keeping the Fund’s net exposure to the equity market at a level similar to a traditional “long-only” strategy, and 2) manage both its long and short positions in a manner that seeks to maximize after-tax return. In combining these approaches, the Fund not only endeavors to outperform traditional “long-only” strategies, but also “long-only” tax aware strategies.

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of equity securities of large capitalization U.S. companies. Large capitalization companies are companies with market capitalizations of at least $4 billion at the time of purchase. “Assets” means net assets, plus the amount of borrowings for investment purposes. These equity securities will be selected from the universe of publicly traded securities with characteristics similar to those of large capitalization companies in the S&P 500 Index. In implementing its strategies, the Fund invests primarily in common stocks of U.S. companies, but may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index, as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping its net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However, the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

In implementing its secondary objective of maximizing after-tax return, the Fund employs a number of tax aware strategies and seeks to minimize shareholder’s tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gain available for distribution. The Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gains, holding securities long enough to avoid short-term capital gains, endeavoring to sell securities with a high cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. Because the Fund also has the ability to short securities, it can implement additional tax-aware strategies that have the potential to increase the after-tax benefits to shareholders. These include the ability to realize additional capital losses regardless of market conditions and to net dividend expenses associated with the Fund’s short positions against the Fund’s dividend income. If the Fund distributes net investment income, the Fund will seek to maximize its ability to distribute dividends designated as qualified dividend income (which is taxed at the lower long-term capital gains rate rather than at the higher tax rate for ordinary income (for non-corporate shareholders)). However, it is possible that a portion of the Fund’s distributions will be taxed as ordinary income.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• high perceived potential reward compared to perceived potential risk
• possible temporary mispricings caused by apparent market overreactions

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income.

Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities held long (or appreciating prices of securities held short), or when the securities the Fund wishes to or is required to sell are illiquid.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

CLASS A SHARES	647	916	1,205	2,027
CLASS C SHARES	279	567	980	2,132

CLASS C SHARES	179	567	980	2,132
SELECT CLASS SHARES	103	334	584	1,300

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of mid cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Mid cap companies are companies with market capitalizations equal to those within the universe of the Russell Midcap Index at the time of purchase. As of the last reconstitution of the Russell Midcap Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a fundamental bottom-up investment process. The adviser seeks to invest in companies with leading competitive advantages, durable business models and sustainable free cash flow generation with management committed to increasing shareholder value. It also looks to invest in securities that are trading at a discount to their intrinsic value.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit- worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance.

What are the Fund’s main investment strategies?

The Fund will invest primarily in long and short positions of equity securities issued by large capitalization companies and intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value).

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of securities of publicly traded large capitalization securities. Large capitalization securities are those equity securities of companies with market capitalizations similar to those within the universe of the S&P 500 Index at the time of purchase. Equity securities in which the Fund invests significantly are common stocks of U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets. In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets, the Fund expects the value of the short positions will decline faster than the long positions. As a result, in declining markets, the Fund expects that it will be able to close out its short positions at a lower cost resulting in additional gain to the Fund.

The Fund intends to invest in a variety of equity securities and, ordinarily, no single equity exposure is expected to make up more than 5% of the gross long exposure except that companies with large weights in the Fund’s benchmark may be held as overweights in the Fund, resulting in positions of greater than 5% in those securities.

Investment Process: The adviser’s investment process is based upon a quantitative multi-factor model with a qualitative over- lay. The adviser uses its quantitative multi-factor model to collect quantitative and fundamental investment data designed to evaluate the relative attractiveness of stocks. The quantitative multi-factor model puts an emphasis on valuation drivers and growth drivers. The valuation drivers include factors such as discounted cash flows and price-to-book values and the growth drivers include factors such as revisions of earning estimates and earnings growth rates. The adviser generally buys long positions in securities that are ranked favorably by its quantitative multi-factor model and sells short securities that are ranked unfavorably. The adviser generally sells long positions in securities that are no longer favorably ranked and covers short positions in securities that are no longer unfavorably ranked. The adviser may also buy, sell, sell short and cover short positions in securities that it views as similarly ranked.

In constructing the Fund’s portfolio, the adviser employs a bottom up stock selection process in combination with its qualitative overlay to determine the weights of each model factor and the risk posture of the Fund. The adviser may invest across different industries and sectors targeting both value-and growth-oriented domestic companies. Viewed sector by sector, the Fund’s net weightings of equity securities will generally be similar to those of its benchmark index, the S&P 500 Index. The adviser uses its qualitative analysis to over and underweight sectors, industries and stocks versus the S&P 500 Index. Sector and industry positioning is used to enhance returns and for risk management.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector swings or other risk factors.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

The Fund has not operated for a calendar year as of the date of this prospectus. Once the Fund has operated for at least one calendar year, a bar chart and performance table will be included in the prospectus to show the performance of the Fund. Although past performance of a Fund is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

[1] "Other Expenses" are based on estimated amounts for the current fiscal year.

[2] The Fund's adviser, administrator and distributor (the Service Providers) have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses, dividend expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, extraordinary expenses and expenses related to the Board of Trustees' deferred compensation plan) exceed 1.20%, 0.60%, and 0.55% of the average daily net assets of the Class R2, Class R5, and Class R6 Shares, respectively. This contract cannot be terminated prior to 11/1/13 at which time the Service Providers will determine whether or not to renew or revise it.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 198% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities. “Assets” means net assets plus the amount of borrowings for investment purposes. In implementing this strategy, the Fund primarily invests in the common stocks of U.S. companies with market capitalizations similar to those within the universe of the S&P 500 Index. As of the last reconstitution of the S&P 500 Index on September 30, 2012, the market capitalizations of the companies in the index ranged from $965 million to $647 billion. Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued. By owning a large number of equity securities within the S&P 500 Index, with an emphasis on those that appear undervalued or fairly valued, the Fund seeks returns that modestly exceed those of the S&P 500 Index over the long term with a modest level of volatility.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price
• Impact on the overall risk of the portfolio relative to the benchmark
• high perceived potential reward compared to perceived potential risk
• possible temporary mispricings caused by apparent market overreactions.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund’s adviser applies an active equity management style focused on identifying attractively valued stocks given their growth potential over a long-term time horizon. The securities held by the Fund will predominantly be of companies with market capitalizations similar to those within the universe of S&P 500/Citigroup Value Index stocks.

While common stocks are the Fund’s primary investment, the Fund may also invest significantly in real estate investment trusts (REITs) and depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser will emphasize companies which are leaders within their sectors. The Fund will also emphasize companies with attractive valuations and low price-to-cash flows ratios. The Fund will seek to earn income by investing in companies that display, or have the potential for displaying, level or rising dividends. The adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals, quantitative screening and proprietary fundamental analysis. The adviser looks for undervalued companies with durable franchises, strong management and the ability to grow their intrinsic value per share.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Strategy Risk. An undervalued stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund.

In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. To the extent that the Fund invests in depositary receipts, such investments are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the S&P 500/Citigroup Value Index, and the Lipper Large-Cap Value Funds Index and Lipper Large-Cap Core Funds Index, both of which are indexes based on the total returns of certain large cap mutual funds as determined by Lipper. Unlike the other index, the Lipper indexes include the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance figures would have been lower.

The Fund seeks to provide high total return from a portfolio of small company stocks.

Fees and Expenses of the Fund

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “How to Do Business with the Funds — SALES CHARGES” on page 79 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, C, Select Shares JPMorgan U.S. Small Company Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	648	973	1,321	2,299
CLASS C SHARES	280	628	1,103	2,415
SELECT CLASS SHARES	104	397	712	1,606

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption A, C, Select Shares JPMorgan U.S. Small Company Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	648	973	1,321	2,299
CLASS C SHARES	180	628	1,103	2,415
SELECT CLASS SHARES	104	397	712	1,606

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 74% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations similar to those within the universe of the Russell 2000^® Index at the time of purchase. As of the last reconstitution of the Russell 2000 Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. Sector by sector, the Fund’s weightings are similar to those of the Russell 2000^® Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. The Fund pursues returns that exceed those of the Russell 2000^® Index while seeking to limit its volatility relative to this index. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Small Cap Company Risk. Investments in small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the performance of the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Russell 2000^® Index and the Lipper Small-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance in the table for Class A and Class C Shares is based on the performance of Select Class Shares prior to their inception on 11/1/07. The actual returns of Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

SELECT CLASS SHARES	104	359	634	1,418

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund will invest primarily in equity securities across all market capitalizations. The Fund may at any given time invest a significant portion of its assets in companies of one particular market capitalization category, such as large-capitalization companies. Equity securities in which the Fund primarily invests include common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals and proprietary fundamental analysis. The adviser’s aim is to identify undervalued companies that have the potential to grow their intrinsic values per share, and to purchase these companies at a discount.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Smaller Cap Company Risk. Because the Fund may invest in equity investments of companies across all market capitalizations, the Fund’s risks increase as it invests more heavily in smaller companies (mid cap and small cap companies). Smaller companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past six calendar years. The table shows the average annual total returns for the past one year, five years and the life of the Fund. The table compares that performance to the Russell 3000^® Value Index and the Lipper Multi-Cap Value Funds Index, an index based on the total return of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance figures would have been lower.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its Assets in long and short positions with respect to equity securities of U.S. companies. These equity securities will primarily be common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. At the same time, by controlling factor or risk exposures through portfolio construction, the Fund seeks to limit its volatility to that of the overall market, as represented by the S&P 500 Index. Short sales involve the sale of a security which the fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The investment process identifies securities that have been mispriced by behavioral biases. Stocks are ranked based on their value, momentum or quality characteristics. In general, stocks are purchased when they are among the top ranked within their sector and are sold if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available. The adviser considers selling short or initiating underweight positions in the lowest ranked securities. Risk or factor exposures are actively managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and style and size characteristics of the Fund.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Mid Cap Company Risk. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty).

With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 95% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments of large and mid capitalization U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund generally defines large capitalization companies as those with a market capitalization over $10 billion at the time of purchase, and mid capitalization companies as those with market capitalization between $1 billion and $10 billion at the time of purchase.

In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 1000 Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative out performance. In identifying high quality securities, the adviser looks for profitable companies with sustainable earnings and disciplined management. In identifying securities that have strong momentum, the adviser looks for securities which have prices and/or earnings that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Because the Fund may invest in large and mid capitalization companies, the Fund’s risks increase as it invests more heavily in mid capitalization companies. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 1000^® Index and the Lipper Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares in the table is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 110% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments of large and mid capitalization companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund generally defines large capitalization companies as those with a market capitalization over $10 billion at the time of purchase, and mid capitalization companies as those with market capitalization between $1 billion and $10 billion, at the time of purchase.

In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 1000 Growth Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative out performance. In identifying high quality securities, the adviser looks for profitable companies with sustainable earnings and disciplined management. In identifying securities that have strong momentum, the adviser looks for securities which have prices and/or earnings that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Mid Cap Company Risk. Because the Fund may invest in large and mid capitalization companies, the Fund’s risks increase as it invests more heavily in mid cap companies. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 1000^® Growth Index and the Lipper Large-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares in the table is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of different U.S. securities, selected from a universe of publicly traded large capitalization securities with characteristics similar to those comprising the Russell 1000 and the S&P 500 Indices. The Fund takes long and short positions mainly in equity securities and derivatives on those securities of companies that each have a market capitalization of at least $4 billion at the time of purchase. Equity securities in which the Fund invests significantly include common stocks of U.S. and foreign companies, including depositary receipts. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities and derivatives on those securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• high potential reward compared to potential risk
• temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

A, Select Shares | JPMorgan Disciplined Equity Fund

JPMorgan Disciplined Equity Fund

Class/Ticker: A/JDEAX; Select/JDESX

What is the goal of the Fund?

The Fund seeks to provide a consistently high total return from a broadly diversified portfolio of equity securities with risk characteristics similar to the Standard and Poor’s 500 Composite Stock Price Index (S&P 500 Index).

Fees and Expenses of the Fund

The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in the J.P. Morgan Funds. More information about these and other discounts is available from your financial intermediary and in “How to Do Business with the Funds — SALES CHARGES” on page 78 of the prospectus and in “PURCHASES, REDEMPTIONS AND EXCHANGES” in Appendix A to Part II of the Statement of Additional Information.

of your investment)

Annual Fund Operating Expenses A, Select Shares JPMorgan Disciplined Equity Fund		Class A	Select Class
Management Fees		0.25%	0.25%
Distribution (Rule 12b-1) Fees		0.25%	none
Other Expenses		0.38%	0.39%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example A, Select Shares JPMorgan Disciplined Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	607	788	984	1,550
SELECT CLASS SHARES	61	201	353	795

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption A, Select Shares JPMorgan Disciplined Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	607	788	984	1,550
SELECT CLASS SHARES	61	201	353	795

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 198% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities. “Assets” means net assets plus the amount of borrowings for investment purposes. In implementing this strategy, the Fund primarily invests in the common stocks of U.S. companies with market capitalizations similar to those within the universe of the S&P 500 Index. As of the last reconstitution of the S&P 500 Index on September 30, 2012, the market capitalizations of the companies in the index ranged from $965 million to $647 billion. Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued. By owning a large number of equity securities within the S&P 500 Index, with an emphasis on those that appear undervalued or fairly valued, the Fund seeks returns that modestly exceed those of the S&P 500 Index over the long term with a modest level of volatility.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as undervalued and considers selling them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price
• Impact on the overall risk of the portfolio relative to the benchmark
• high perceived potential reward compared to perceived potential risk
• possible temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the S&P 500 Index and the Lipper Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 57% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments across all market capitalizations. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund will generally invest in companies with a market capitalization of $500 million or greater at the time of purchase. In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 3000 Index that the adviser believes are undervalued and/or have strong momentum. In identifying securities that have strong momentum, the adviser looks for securities which have prices that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Smaller Cap Company Risk. Although the Fund may invest in equity investments of companies across all market capitalizations, the Fund’s risks increase as it invests in smaller companies (mid cap and small cap companies). Smaller companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 3000^® Index and the Lipper Multi-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The Fund’s performance prior to 4/10/06 may be less pertinent for investors considering whether to purchase shares of the Fund because of changes made to the Fund’s investment policies beginning at that time. The performance of the Class A and Class C Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations similar to those within the universe of the Russell 2000^® Index at the time of purchase. As of the last reconstitution of the Russell 2000 Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. Sector by sector, the Fund’s weightings are similar to those of the Russell 2000^® Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. The Fund pursues returns that exceed those of the Russell 2000^® Index while seeking to limit its volatility relative to this index. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Small Cap Company Risk. Investments in small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the performance of the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Russell 2000^® Index and the Lipper Small-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance in the table for Class A and Class C Shares is based on the performance of Select Class Shares prior to their inception on 11/1/07. The actual returns of Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

Select Shares | JPMorgan Small Cap Core Fund

JPMorgan Small Cap Core Fund

Class/Ticker: Select/VSSCX

What is the goal of the Fund?

The Fund seeks capital growth over the long term.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the
value of your investment)

Annual Fund Operating Expenses		Select Shares JPMorgan Small Cap Core Fund Select Class
Management Fees		0.65%
Distribution (Rule 12b-1) Fees		none
Other Expenses		0.37%
Shareholder Service Fees		0.25%
Remainder of Other Expenses		0.12%
Total Annual Fund Operating Expenses		1.02%
Fee Waivers and Expense Reimbursements	[1]	(0.22%)
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	[1]	0.80%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES YOUR
COST WOULD BE:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
Select Shares JPMorgan Small Cap Core Fund SELECT CLASS SHARES	82	303	542	1,228

WHETHER OR NOT YOU SELL YOUR SHARES YOUR
COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Select Shares JPMorgan Small Cap Core Fund SELECT CLASS SHARES	82	303	542	1,228

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations equal to those within the universe of Russell 2000® Index at the time of purchase. As of the last reconstitution of the Russell 2000 Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. Sector by sector, the Fund’s weightings are similar to those of the Russell 2000 Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund pursues returns that exceed those of the Russell 2000 Index while seeking to limit its volatility relative to this index. In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Small Cap Company Risk. Investments in small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the Russell 2000^® Index and Lipper Small-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest primarily in long and short positions of equity securities issued by large capitalization companies and intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value).

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of securities of publicly traded large capitalization securities. Large capitalization securities are those equity securities of companies with market capitalizations similar to those within the universe of the S&P 500 Index at the time of purchase. Equity securities in which the Fund invests significantly are common stocks of U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets. In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets, the Fund expects the value of the short positions will decline faster than the long positions. As a result, in declining markets, the Fund expects that it will be able to close out its short positions at a lower cost resulting in additional gain to the Fund.

The Fund intends to invest in a variety of equity securities and, ordinarily, no single equity exposure is expected to make up more than 5% of the gross long exposure except that companies with large weights in the Fund’s benchmark may be held as overweights in the Fund, resulting in positions of greater than 5% in those securities.

Investment Process: The adviser’s investment process is based upon a quantitative multi-factor model with a qualitative overlay. The adviser uses its quantitative multi-factor model to collect quantitative and fundamental investment data designed to evaluate the relative attractiveness of stocks. The quantitative multi-factor model puts an emphasis on valuation drivers and growth drivers. The valuation drivers include factors such as discounted cash flows and price-to-book values and the growth drivers include factors such as revisions of earning estimates and earnings growth rates. The adviser generally buys long positions in securities that are ranked favorably by its quantitative multi-factor model and sells short securities that are ranked unfavorably. The adviser generally sells long positions in securities that are no longer favorably ranked and covers short positions in securities that are no longer unfavorably ranked. The adviser may also buy, sell, sell short and cover short positions in securities that it views as similarly ranked.

In constructing the Fund’s portfolio, the adviser employs a bottom up stock selection process in combination with its qualitative overlay to determine the weights of each model factor and the risk posture of the Fund. The adviser may invest across different industries and sectors targeting both value-and growth-oriented domestic companies. Viewed sector by sector, the Fund’s net weightings of equity securities will generally be similar to those of its benchmark index, the S&P 500 Index. The adviser uses its qualitative analysis to over and underweight sectors, industries and stocks versus the S&P 500 Index. Sector and industry positioning is used to enhance returns and for risk management.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector swings or other risk factors.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

SELECT CLASS SHARES	182	634	1,113	2,435

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 129% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of different U.S. securities, selected from a universe of publicly traded large capitalization securities with characteristics similar to those comprising the Russell 1000 and the S&P 500 Indices. The Fund takes long and short positions mainly in equity securities and derivatives on those securities of companies that each have a market capitalization of at least $4 billion at the time of purchase. Equity securities in which the Fund invests significantly include common stocks of U.S. and foreign companies, including depositary receipts. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities and derivatives on those securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• high potential reward compared to potential risk
• temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal period (October 3, 2011 through June 30, 2012), the Fund’s portfolio turnover rate (including short sales) was 80% of the average value of its portfolio.

What are the Fund’s main investment strategies?

In seeking to meet its objectives, the Fund will 1) take long and short positions in equity securities of U.S. large-cap companies in an effort to increase the Fund’s return relative to the S&P 500 Index, the Fund’s benchmark, and to traditional large-cap strategies which do not have the ability to sell stock short, while keeping the Fund’s net exposure to the equity market at a level similar to a traditional “long-only” strategy, and 2) manage both its long and short positions in a manner that seeks to maximize after-tax return. In combining these approaches, the Fund not only endeavors to outperform traditional “long-only” strategies, but also “long-only” tax aware strategies.

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of equity securities of large capitalization U.S. companies. Large capitalization companies are companies with market capitalizations of at least $4 billion at the time of purchase. “Assets” means net assets, plus the amount of borrowings for investment purposes. These equity securities will be selected from the universe of publicly traded securities with characteristics similar to those of large capitalization companies in the S&P 500 Index. In implementing its strategies, the Fund invests primarily in common stocks of U.S. companies, but may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index, as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping its net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However, the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

In implementing its secondary objective of maximizing after-tax return, the Fund employs a number of tax aware strategies and seeks to minimize shareholder’s tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gain available for distribution. The Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gains, holding securities long enough to avoid short-term capital gains, endeavoring to sell securities with a high cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. Because the Fund also has the ability to short securities, it can implement additional tax-aware strategies that have the potential to increase the after-tax benefits to shareholders. These include the ability to realize additional capital losses regardless of market conditions and to net dividend expenses associated with the Fund’s short positions against the Fund’s dividend income. If the Fund distributes net investment income, the Fund will seek to maximize its ability to distribute dividends designated as qualified dividend income (which is taxed at the lower long-term capital gains rate rather than at the higher tax rate for ordinary income (for non-corporate shareholders)). However, it is possible that a portion of the Fund’s distributions will be taxed as ordinary income.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• high perceived potential reward compared to perceived potential risk
• possible temporary mispricings caused by apparent market overreactions

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income.

Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities held long (or appreciating prices of securities held short), or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

The Fund commenced operations on October 3, 2011 and, therefore, does not have a full calendar year of performance. Once the Fund has operated for at least one calendar year, a bar chart and performance table will be included in the prospectus to show the performance of the Fund. Although past performance of the Fund is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests in a focused portfolio of equity securities of large capitalization companies. Large cap companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. Typically, the Fund invests in common stocks of companies with a history of above-average growth or companies expected to enter periods of above-average growth. Although the Fund will invest primarily in equity securities of U.S. companies, it may invest up to 20% of its total assets in foreign securities, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund is non-diversified.

Investment Process: The Fund’s adviser will utilize a combination of qualitative analysis and quantitative metrics in order to seek to achieve target returns which are higher than the Fund’s benchmark while attempting to maintain a moderate risk profile. In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. The adviser looks for companies with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may also trade at higher multiples of current earnings, compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets.

Investments in foreign issuers are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 66% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Drawing on a variety of analytical tools, the Fund’s adviser allocates assets among various types of equity and fixed income investments, based on the following model allocation:

• 30%–75% U.S. equity securities, including small–, medium– and large-cap securities
• 25%–50% U.S. and foreign fixed income securities
• 0%–30% foreign equity securities

The Fund invests in separate underlying strategies investing directly in individual securities or in other J.P. Morgan Funds, across asset classes, including: U.S. equity and developed international equity across market capitalizations, emerging markets equity, domestic and foreign fixed income, high yield fixed income, emerging markets debt, and real estate investment trusts (REITs).

The adviser may periodically increase or decrease the Fund’s actual asset allocation according to the relative attractiveness of each asset class.

Within its equity allocations, the Fund primarily invests in the common stock and convertible securities of U.S. and foreign companies.

Within its fixed income allocations, the Fund primarily invests in corporate bonds, mortgage-backed securities, mortgage “dollar rolls” and U.S. government securities. The Fund’s bond investments will primarily be rated investment grade by a national rating organization but the Fund may also invest up to 15% of its assets in certain high yield, high risk, non-investment grade securities (also known as junk bonds). This limit will include all investments held directly by the Fund, as well as J.P. Morgan Funds held by the Fund which invest primarily in high yield, non-investment grade securities.

In addition to purchasing securities directly, the Fund may invest up to 30% of its assets in shares of other J.P. Morgan Funds in order to expose the Fund to certain asset classes when the adviser believes it is appropriate.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. With respect to its fixed income allocations, the Fund may use futures contracts to manage and hedge interest rate risk associated with these investments, as well as to lengthen or shorten the duration of this portion of the portfolio. With respect to its equity and fixed income allocations, the Fund may use futures contracts to gain or reduce exposure to all or a portion of the stock or fixed income markets, respectively and for cash management. The Fund may use forward foreign currency exchange contracts to hedge or manage its foreign currency risk, as well as to gain exposure to certain currencies.

The adviser establishes the strategic and tactical allocation for the Fund and makes the day-to-day decisions concerning strategies and overall construction of the Fund. As attractive investments arise across asset classes and strategies, the adviser attempts to capture these opportunities by allocating the Fund’s assets among strategies and asset classes within pre-defined ranges.

Investment decisions within strategies and asset classes are implemented either by the portfolio managers of the Fund’s underlying strategies who select individual securities for the Fund or with the Fund’s purchase of other J.P. Morgan Funds.

The frequency with which the Fund buys and sells underlying investments will vary from year to year, depending on, but not limited to: market conditions, performance of the underlying investments, and changes in the adviser’s investment views.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

The Fund is exposed to the risks summarized below through both its direct investments and its investments in underlying funds.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

Foreign Securities and Emerging Markets Risks. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. These risks are magnified in countries in “emerging markets.” Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier, more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Investments in Mutual Funds Risk. To the extent the Fund invests in underlying J.P. Morgan Funds, the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by those underlying funds. Because the adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest.

Income Securities Risk. Investments in income securities will change in value based on changes in interest rates and are subject to the risk that a counterparty will fail to make payments when due or default. If interest rates rise, the value of the Fund’s income securities generally drops. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Mortgage-related and asset-backed securities including so called “sub-prime” mortgages are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid.

Credit Risk. Some of the Fund’s investments are subject to the risk that a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

High Yield Securities Risk. Some of the Fund’s investments are in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed (known as junk bonds). These investments are considered to be speculative and are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and potential illiquidity.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund, will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures and foreign currency exchange contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the Diversified Composite Benchmark, a customized benchmark, the Morgan Stanley Capital International (MSCI) World Index (net of foreign withholding taxes), a broad-based securities market index, and the Lipper Mixed-Asset Target Allocation Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The Diversified Composite Benchmark is a composite benchmark of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of MSCI World (60%) and Barclays U.S. Aggregate (40%) indexes. The performance of the Fund’s former benchmark, the S&P 500 Index, and former composite benchmark (which was composed of the S&P 500 (60%) and Barclays U.S. Aggregate (40%) indexes) is also presented in the table. The performance in the table for Class A, Class B, and Class C Shares is based on the performance of Select Class Shares prior to their inception on 3/24/03. The actual returns of Class A, Class B and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal period (July 29, 2011 through June 30, 2012), the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a non-diversified equity portfolio which is normally managed as a core portfolio, but which has the ability to proactively invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser. The Fund invests in a limited number of U.S. equity securities, generally not more than 40. In choosing securities, the Fund seeks to invest in companies with one or more of the following characteristics:

• A durable franchise
• A sustainable competitive position relative to its peers
• A market leader
• A strong management team focused on increasing shareholder value
• A strong balance sheet.

The size of the allocation of the Fund to growth and value securities will vary based on market conditions, and the convictions of the adviser each ranging from 35% to 65% of the equity investments in the Fund.

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund typically invests in equity securities with market capitalizations of $1 billion or more. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs), but it may also invest up to 20% of its assets in common stocks of foreign companies, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

If the Fund’s portfolio managers cannot find attractive investments, the Fund may invest up to 20% of its assets in cash and cash equivalents until appropriate investments are identified.

Investment Process: In managing the Fund, the portfolio managers employ a process that combines research, valuation and stock selection.

In selecting growth stocks, the adviser focuses on companies whose revenue growth potential is underappreciated by investors, specifically looking for companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. These companies have one or more of the following characteristics:

• A favorable supply/demand imbalance for the company’s product or service
• Underappreciated growth opportunities
• Differentiated business model
• Ability to gain market share
• Growth opportunities in emerging industries or those that emerge from industry changes

In selecting value stocks, the adviser seeks to invest in companies which have durable franchises and which appear to be undervalued and have the ability to grow intrinsic value per share. Companies with durable franchises generally have a sustainable competitive position relative to peers, high returns on capital, a diversified client or asset base and a strong brand.

The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be attractively valued. Investments may also be sold if a portfolio manager identifies a stock that he believes offers a better investment opportunity or to reallocate the Fund’s assets between growth and value securities.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Non-Diversified Fund Risk. The Fund is non-diversified and typically invests in no more than 40 securities. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities. The value of the Fund’s shares may also be more volatile than the value of a Fund which invests in more securities.

Strategy Risk. Although the Fund is normally managed as a core portfolio, it may invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser.

If the Fund invests more heavily in growth securities, it will be more subject to risks related to growth investing. Specifically, growth stocks may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

If the Fund invests more heavily in value securities, it will be more subject to risks related to value investing. Specifically, a value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Smaller Cap Company Risk. Investments in companies with capitalizations as low as $1 billion may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit- worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations equal to those within the universe of Russell 2000® Index at the time of purchase. As of the last reconstitution of the Russell 2000 Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. Sector by sector, the Fund’s weightings are similar to those of the Russell 2000 Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. In implementing its main strategies, the Fund’s investments are primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund pursues returns that exceed those of the Russell 2000 Index while seeking to limit its volatility relative to this index. In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios. In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

Select Shares | JPMorgan Dynamic Growth Fund

JPMorgan Dynamic Growth Fund

Class/Ticker: Select/JDGSX

What is the goal of the Fund?

The Fund seeks long-term capital growth.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the
value of your investment)

Annual Fund Operating Expenses		Select Shares JPMorgan Dynamic Growth Fund Select Class
Management Fees		0.60%
Distribution (Rule 12b-1) Fees		none
Other Expenses		0.59%
Shareholder Service Fees		0.25%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR

COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Select Shares JPMorgan Dynamic Growth Fund SELECT CLASS SHARES	103	362	641	1,438

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 99% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests in a focused portfolio of equity securities of large capitalization companies. Large cap companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. Typically, the Fund invests in common stocks of companies with a history of above-average growth or companies expected to enter periods of above-average growth. Although the Fund will invest primarily in equity securities of U.S. companies, it may invest up to 20% of its total assets in foreign securities, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund is non-diversified.

Investment Process: The Fund’s adviser will utilize a combination of qualitative analysis and quantitative metrics in order to seek to achieve target returns which are higher than the Fund’s benchmark while attempting to maintain a moderate risk profile. In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. The adviser looks for companies with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may also trade at higher multiples of current earnings, compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past four calendar years. The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the Russell 1000^® Growth Index and the Lipper Large-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Subsequent to the inception of the Fund on 11/30/07 until 8/6/10, the Fund did not experience any shareholder purchase and sale activity. If such shareholder activity had occurred, the Fund’s performance may have been impacted. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal period (October 3, 2011 through June 30, 2012), the Fund’s portfolio turnover rate (including short sales) was 80% of the average value of its portfolio.

What are the Fund’s main investment strategies?

In seeking to meet its objectives, the Fund will 1) take long and short positions in equity securities of U.S. large-cap companies in an effort to increase the Fund’s return relative to the S&P 500 Index, the Fund’s benchmark, and to traditional large-cap strategies which do not have the ability to sell stock short, while keeping the Fund’s net exposure to the equity market at a level similar to a traditional “long-only” strategy, and 2) manage both its long and short positions in a manner that seeks to maximize after-tax return. In combining these approaches, the Fund not only endeavors to outperform traditional “long-only” strategies, but also “long-only” tax aware strategies.

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of equity securities of large capitalization U.S. companies. Large capitalization companies are companies with market capitalizations of at least $4 billion at the time of purchase. “Assets” means net assets, plus the amount of borrowings for investment purposes. These equity securities will be selected from the universe of publicly traded securities with characteristics similar to those of large capitalization companies in the S&P 500 Index. In implementing its strategies, the Fund invests primarily in common stocks of U.S. companies, but may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index, as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping its net exposure to the market at a level similar to a traditional “long-only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However, the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

In implementing its secondary objective of maximizing after-tax return, the Fund employs a number of tax aware strategies and seeks to minimize shareholder’s tax liability in connection with the Fund’s distribution of realized capital gain by minimizing the net gain available for distribution. The Fund typically sells securities when the anticipated performance benefit justifies the resulting gain. This strategy often includes minimizing the sale of securities with large unrealized gains, holding securities long enough to avoid short-term capital gains, endeavoring to sell securities with a high cost basis first and offsetting capital gains realized in one security by selling another security at a capital loss. Because the Fund also has the ability to short securities, it can implement additional tax-aware strategies that have the potential to increase the after-tax benefits to shareholders. These include the ability to realize additional capital losses regardless of market conditions and to net dividend expenses associated with the Fund’s short positions against the Fund’s dividend income. If the Fund distributes net investment income, the Fund will seek to maximize its ability to distribute dividends designated as qualified dividend income (which is taxed at a lower long-term capital gains rate rather than at the higher tax rate for ordinary income (for non-corporate shareholders)). However, it is possible that a portion of the Fund’s distributions will be taxed as ordinary income.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• high perceived potential reward compared to perceived potential risk
• possible temporary mispricings caused by apparent market overreactions

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Tax Aware Investing Risk. The Fund’s tax aware strategies may reduce your taxable income, but will not eliminate it. These strategies may require trade-offs that reduce pretax income.

Managing the Fund to maximize after-tax returns may also potentially have a negative effect on the Fund’s performance. Because tax consequences are considered in managing the Fund, the Fund’s pre-tax performance may be lower than that of a similar fund that is not tax-managed.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities held long (or appreciating prices of securities held short), or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

The Fund commenced operations on October 3, 2011 and, therefore, does not have a full calendar year of performance. Once the Fund has operated for at least one calendar year, a bar chart and performance table will be included in the prospectus to show the performance of the Fund. Although past performance of the Fund is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal period (July 29, 2011 through June 30, 2012), the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is a non-diversified equity portfolio which is normally managed as a core portfolio, but which has the ability to proactively invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser. The Fund invests in a limited number of U.S. equity securities, generally not more than 40. In choosing securities, the Fund seeks to invest in companies with one or more of the following characteristics:

• A durable franchise
• A sustainable competitive position relative to its peers
• A market leader
• A strong management team focused on increasing shareholder value
• A strong balance sheet.

The size of the allocation of the Fund to growth and value securities will vary based on market conditions, and the convictions of the adviser each ranging from 35% to 65% of the equity investments in the Fund.

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund typically invests in equity securities with market capitalizations of $1 billion or more. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs), but it may also invest up to 20% of its assets in common stocks of foreign companies, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

If the Fund’s portfolio managers cannot find attractive investments, the Fund may invest up to 20% of its assets in cash and cash equivalents until appropriate investments are identified.

Investment Process: In managing the Fund, the portfolio managers employ a process that combines research, valuation and stock selection.

In selecting growth stocks, the adviser focuses on companies whose revenue growth potential is underappreciated by investors, specifically looking for companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. These companies have one or more of the following characteristics:

• A favorable supply/demand imbalance for the company’s product or service
• Underappreciated growth opportunities
• Differentiated business model
• Ability to gain market share
• Growth opportunities in emerging industries or those that emerge from industry changes

In selecting value stocks, the adviser seeks to invest in companies which have durable franchises and which appear to be undervalued and have the ability to grow intrinsic value per share. Companies with durable franchises generally have a sustainable competitive position relative to peers, high returns on capital, a diversified client or asset base and a strong brand.

The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be attractively valued. Investments may also be sold if a portfolio manager identifies a stock that he believes offers a better investment opportunity or to reallocate the Fund’s assets between growth and value securities.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Non-Diversified Fund Risk. The Fund is non-diversified and typically invests in no more than 40 securities. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities. The value of the Fund’s shares may also be more volatile than the value of a Fund which invests in more securities.

Strategy Risk. Although the Fund is normally managed as a core portfolio, it may invest more heavily in either growth or value securities depending on market conditions and the convictions of the adviser.

If the Fund invests more heavily in growth securities, it will be more subject to risks related to growth investing. Specifically, growth stocks may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

If the Fund invests more heavily in value securities, it will be more subject to risks related to value investing. Specifically, a value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Smaller Cap Company Risk. Investments in companies with capitalizations as low as $1 billion may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit- worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

The Fund commenced operations on July 29, 2011 and, therefore, does not have a full calendar year of performance. Once the Fund has operated for at least one calendar year, a bar chart and performance table will be included in the prospectus to show the performance of the Fund. Although past performance is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will invest in equity securities of large capitalization, U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large capitalization companies are companies with market capitalizations of at least $4 billion at the time of purchase. In implementing its strategy, the Fund invests primarily in common stocks, real estate investment trusts (REITs) and depositary receipts. The adviser also generally is sector neutral relative to the S&P 500 Index and emphasizes stock selection as the primary means of generating returns.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies that do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the Fund’s adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser buys and sells, as well as shorts and covers shorts in, equity securities and derivatives on those securities according to its own policies, using the research and valuation rankings as a basis. In general, the adviser buys and covers shorts in equity securities that are identified as undervalued and considers selling or shorting them when they appear overvalued. Along with attractive valuation, the adviser often considers a number of other criteria such as:

• catalysts that could trigger a rise in a stock’s price
• impact on the overall risk of the portfolio relative to the benchmark
• high potential reward compared to potential risk and
• temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. To the extent the Fund invests in depositary receipts, such investments are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund, will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

R5 Shares | JPMorgan Dynamic Growth Fund

JPMorgan Dynamic Growth Fund

What is the goal of the Fund?

The Fund seeks long-term capital growth.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the value
of your investment)

Annual Fund Operating Expenses		R5 Shares JPMorgan Dynamic Growth Fund Class R5
Management Fees		0.60%
Distribution (Rule 12b-1) Fees		none
Other Expenses		0.39%
Shareholder Service Fees		0.05%
Remainder of Other Expenses		0.34%
Acquired Fund Fees and Expenses		0.01%
Total Annual Fund Operating Expenses		1.00%
Fee Waivers and Expense Reimbursements	[1]	(0.19%)
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	[1]	0.81%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
R5 Shares JPMorgan Dynamic Growth Fund CLASS R5 SHARES	83	299	534	1,207

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
R5 Shares JPMorgan Dynamic Growth Fund CLASS R5 SHARES	83	299	534	1,207

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 99% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests in a focused portfolio of equity securities of large capitalization companies. Large cap companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. Typically, the Fund invests in common stocks of companies with a history of above-average growth or companies expected to enter periods of above-average growth. Although the Fund will invest primarily in equity securities of U.S. companies, it may invest up to 20% of its total assets in foreign securities, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund is non-diversified.

Investment Process: The Fund’s adviser will utilize a combination of qualitative analysis and quantitative metrics in order to seek to achieve target returns which are higher than the Fund’s benchmark while attempting to maintain a moderate risk profile. In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. The adviser looks for companies with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may trade at higher multiples of current earnings, compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R5 Shares has varied from year to year for the past four calendar years. The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the Russell 1000^® Growth Index and the Lipper Large-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Subsequent to the inception of the Fund on 11/30/07 until 8/6/10, the Fund did not experience any shareholder purchase and sale activity. If such shareholder activity had occurred, the Fund’s performance may have been impacted. Unlike the other index, the Lipper index does include the expense of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance.

What are the Fund’s main investment strategies?

The Fund will invest primarily in long and short positions of equity securities issued by large capitalization companies and intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value).

Under normal circumstances, at least 80% of the value of the Fund’s Assets, which are expected to include both long and short positions, will consist of securities of publicly traded large capitalization securities. Large capitalization securities are those equity securities of companies with market capitalizations similar to those within the universe of the S&P 500 Index at the time of purchase. Equity securities in which the Fund invests significantly are common stocks of U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. Selling stock short allows the Fund to more fully exploit insights in stocks that the adviser expects to underperform, as well as enabling the Fund to establish additional long positions while keeping the Fund’s net exposure to the market at a level similar to a traditional “long only” strategy. Short sales involve the sale of a security which the Fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the Fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets. In rising markets, the Fund expects that the long positions will appreciate more rapidly than the short positions, and in declining markets, the Fund expects the value of the short positions will decline faster than the long positions. As a result, in declining markets, the Fund expects that it will be able to close out its short positions at a lower cost resulting in additional gain to the Fund.

The Fund intends to invest in a variety of equity securities and, ordinarily, no single equity exposure is expected to make up more than 5% of the gross long exposure except that companies with large weights in the Fund’s benchmark may be held as overweights in the Fund, resulting in positions of greater than 5% in those securities.

Investment Process: The adviser’s investment process is based upon a quantitative multi-factor model with a qualitative overlay. The adviser uses its quantitative multi-factor model to collect quantitative and fundamental investment data designed to evaluate the relative attractiveness of stocks. The quantitative multi-factor model puts an emphasis on valuation drivers and growth drivers. The valuation drivers include factors such as discounted cash flows and price-to-book values and the growth drivers include factors such as revisions of earning estimates and earnings growth rates. The adviser generally buys long positions in securities that are ranked favorably by its quantitative multi-factor model and sells short securities that are ranked unfavorably. The adviser generally sells long positions in securities that are no longer favorably ranked and covers short positions in securities that are no longer unfavorably ranked. The adviser may also buy, sell, sell short and cover short positions in securities that it views as similarly ranked.

In constructing the Fund’s portfolio, the adviser employs a bottom up stock selection process in combination with its qualitative overlay to determine the weights of each model factor and the risk posture of the Fund. The adviser may invest across different industries and sectors targeting both value-and growth-oriented domestic companies. Viewed sector by sector, the Fund’s net weightings of equity securities will generally be similar to those of its benchmark index, the S&P 500 Index. The adviser uses its qualitative analysis to over and underweight sectors, industries and stocks versus the S&P 500 Index. Sector and industry positioning is used to enhance returns and for risk management.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting the Fund’s exposure to domestic stock market movements, capitalization, sector swings or other risk factors.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

The Fund has not operated for a calendar year as of the date of this prospectus. Once the Fund has operated for at least one calendar year, a bar chart and performance table will be included in the prospectus to show the performance of the Fund. Although past performance of a Fund is no guarantee of how it will perform in the future, historical performance may give you some indication of the risks of investing in the Fund.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its strategy, the Fund primarily invests in common stocks of large- and medium-capitalization U.S. companies, but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts.

Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund focuses on those equity securities that it considers most undervalued and seeks to outperform the S&P 500 through superior stock selection. By emphasizing undervalued equity securities, the Fund seeks to produce returns that exceed those of the S&P 500 Index. At the same time, by controlling the sector weightings of the Fund so they can differ only moderately from the sector weightings of the S&P 500 Index, the Fund seeks to limit its volatility to that of the overall market, as represented by this index.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as undervalued and considers selling them when they appear to be overvalued. Along with attractive valuation, the adviser often considers a number of other criteria:

• catalysts that could trigger a rise in a stock’s price
• high potential reward compared to potential risk
• temporary mispricings caused by apparent market overreactions.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. The securities of mid cap companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Strategy Risk. An undervalued stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment and less stringent investor protection and disclosure standards of foreign markets.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, B, C, Select Shares JPMorgan Small Cap Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	651	941	1,251	2,129
CLASS B SHARES	684	892	1,227	2,105
CLASS C SHARES	284	592	1,027	2,234
SELECT CLASS SHARES	103	356	628	1,406

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption A, B, C, Select Shares JPMorgan Small Cap Equity Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	651	941	1,251	2,129
CLASS B SHARES	184	592	1,027	2,105
CLASS C SHARES	184	592	1,027	2,234
SELECT CLASS SHARES	103	356	628	1,406

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000^® Index stocks at the time of purchase. As of the last reconstitution of the Russell 2000 Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In implementing its main strategies, the Fund invests primarily in common stocks.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a fundamental bottom-up investment process. The adviser seeks to invest in companies with leading competitive advantages, predictable and durable business models and sustainable free cash flow generation with management committed to increasing intrinsic value.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Small Cap Company Risk. Investments in small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Russell 2000^® Index and the Lipper Small-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class C Shares prior to their inception on 2/19/05 is based on the performance of Class B Shares of the Fund, whose expenses are substantially similar to those of Class C Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance figures would have been lower.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will invest primarily in equity securities across all market capitalizations. The Fund may at any given time invest a significant portion of its assets in companies of one particular market capitalization category, such as large-capitalization companies. Equity securities in which the Fund primarily invests include common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals and proprietary fundamental analysis. The adviser’s aim is to identify undervalued companies that have the potential to grow their intrinsic values per share, and to purchase these companies at a discount.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Smaller Cap Company Risk. Because the Fund may invest in equity investments of companies across all market capitalizations, the Fund’s risks increase as it invests more heavily in smaller companies (mid cap and small cap companies). Smaller companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The table compares that performance to the Russell 3000^® Value Index and the Lipper Multi-Cap Value Funds Index, an index based on the total return of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance figures would have been lower.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, C, Select Shares JPMorgan U.S. Dynamic Plus Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	709	1,237	1,790	3,291
CLASS C SHARES	344	900	1,581	3,398
SELECT CLASS SHARES	169	674	1,205	2,661

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption A, C, Select Shares JPMorgan U.S. Dynamic Plus Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	709	1,237	1,790	3,291
CLASS C SHARES	244	900	1,581	3,398
SELECT CLASS SHARES	169	674	1,205	2,661

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate (including short sales) was 583% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund will invest at least 80% of its Assets in long and short positions with respect to equity securities of U.S. companies. These equity securities will primarily be common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes.

“Plus” in the Fund’s name refers to the additional return the Fund endeavors to add both relative to the S&P 500 Index as well as relative to traditional strategies which do not have the ability to sell stock short. At the same time, by controlling factor or risk exposures through portfolio construction, the Fund seeks to limit its volatility to that of the overall market, as represented by the S&P 500 Index. Short sales involve the sale of a security which the fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the Fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the Fund.

The Fund intends to maintain an approximate net 100% long exposure to the equity market (long market value minus short market value). However the long and short positions held by the Fund will vary in size as market opportunities change. The Fund’s long positions and their equivalents will range between 90% and 150% of the value of the Fund’s net assets. The Fund’s short positions will range between 0% and 50% of the value of the Fund’s net assets.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The investment process identifies securities that have been mispriced by behavioral biases. Stocks are ranked based on their value, momentum or quality characteristics. In general, stocks are purchased when they are among the top ranked within their sector and are sold if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available. The adviser considers selling short or initiating underweight positions in the lowest ranked securities. Risk or factor exposures are actively managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and style and size characteristics of the Fund.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Short Selling Risk. The Fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the Fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the Fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the Fund may be reduced or eliminated or the short sale may result in a loss. The Fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security. Furthermore, taking short positions in securities results in a form of leverage which may cause the Fund to be more volatile.

Mid Cap Company Risk. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns for the past one year, five years and the life of the Fund. The table compares that performance to the Standard & Poor’s 500 Composite Stock Price Index (“S&P 500 Index”) and the Lipper Extended U.S. Large-Cap Core Funds Average, an average based on the total return of all funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

CLASS A SHARES	647	962	1,299	2,250
CLASS C SHARES	179	613	1,072	2,347
SELECT CLASS SHARES	93	376	680	1,544

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 55% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of mid cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Mid cap companies are companies with market capitalizations equal to those within the universe of the Russell Midcap^® Index securities at the time of purchase. As of the last reconstitution of the Russell Midcap Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion. In implementing its main strategies, the Fund invests primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the adviser employs a bottom-up approach to stock selection, constructing portfolios based on company fundamentals, quantitative screening and proprietary fundamental analysis. The Fund focuses on mid-sized companies with increasing market share, strong earnings prospects and sustainable free cash flows as compared to their competitors. The Fund also looks for dominant franchises with predictable business models deemed capable of achieving sustained growth and undervalued companies with the potential to grow their intrinsic value per share.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Russell Midcap^® Index and the Lipper Mid-Cap Core Funds Index, an index based on the total returns of certain mutual funds within mid cap funds category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of the Class A and Class C Shares is based on the performance of the Select Class Shares prior to their inception on 11/2/09. The actual returns of the Class A and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

SELECT CLASS SHARES	83	349	635	1,452

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity investments of large and mid capitalization companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund generally defines large capitalization companies as those with a market capitalization over $10 billion at the time of purchase, and mid capitalization companies as those with market capitalization between $1 billion and $10 billion, at the time of purchase.

In implementing its main strategies, the Fund invests primarily in a broad portfolio of common stocks of companies within the Russell 1000 Value Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative out performance. In identifying high quality securities, the adviser looks for profitable companies with sustainable earnings and disciplined management. In identifying securities that have strong momentum, the adviser looks for securities which have prices and/or earnings that have been increasing and that the adviser believes will continue to increase.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: The Fund has an actively managed strategy that employs an investment process based on behavioral finance principles. Behavioral finance theorizes that investors behave irrationally in systematic and predictable ways because human psychology affects investment decision-making. This investor behavior results in market inefficiencies that persist over time. The Fund seeks to capitalize on these market anomalies through a disciplined and dispassionate investment process.

The Fund will sell a stock if the adviser determines that the issuer no longer meets the Fund’s investment criteria or if the adviser believes that more attractive opportunities are available.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Mid Cap Company Risk. Because the Fund may invest in large- and mid-capitalization companies, the Fund’s risks increase as it invests more heavily in mid-capitalization companies. Investments in mid cap companies may be riskier than investments in larger, more established companies. Mid cap companies may be more volatile and more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past eight calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. The table compares that performance to the Russell 1000^® Value Index and the Lipper Large-Cap Value Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Small cap companies are companies with market capitalizations equal to those within the universe of the Russell 2000^® Growth Index and/or with market capitalizations of less than $3.5 billion at the time of purchase. As of the date of the last reconstitution of the Russell 2000 Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In implementing its main strategies, the Fund invests primarily in common stocks.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

Investment Process: In managing the Fund, the Fund’s adviser seeks to outperform the Fund’s benchmark while maintaining a moderate risk profile. The adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. Growth companies purchased for the Fund include those with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Small Cap Company Risk. Investments in small cap companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Russell 2000^® Growth Index and Lipper Small-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance figures would have been lower.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/13 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, B, C, Select Shares JPMorgan Diversified Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	575	867	1,180	2,065

CLASS C SHARES	283	591	1,026	2,234
SELECT CLASS SHARES	106	359	631	1,409

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

CLASS C SHARES	183	591	1,026	2,234
SELECT CLASS SHARES	106	359	631	1,409

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 66% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Drawing on a variety of analytical tools, the Fund’s adviser allocates assets among various types of equity and fixed income investments, based on the following model allocation:

• 30%–75% U.S. equity securities, including small–, medium– and large-cap securities
• 25%–50% U.S. and foreign fixed income securities
• 0%–30% foreign equity securities

The Fund invests in separate underlying strategies investing directly in individual securities or in other J.P. Morgan Funds, across asset classes, including: U.S. equity and developed international equity across market capitalizations, emerging markets equity, domestic and foreign fixed income, high yield fixed income, emerging markets debt, and real estate investment trusts (REITs).

The adviser may periodically increase or decrease the Fund’s actual asset allocation according to the relative attractiveness of each asset class.

Within its equity allocations, the Fund primarily invests in the common stock and convertible securities of U.S. and foreign companies.

Within its fixed income allocations, the Fund primarily invests in corporate bonds, mortgage-backed securities, mortgage “dollar rolls” and U.S. government securities. The Fund’s bond investments will primarily be rated investment grade by a national rating organization but the Fund may also invest up to 15% of its assets in certain high yield, high risk, non-investment grade securities (also known as junk bonds). This limit will include all investments held directly by the Fund, as well as J.P. Morgan Funds held by the Fund which invest primarily in high yield, non-investment grade securities.

In addition to purchasing securities directly, the Fund may invest up to 30% of its assets in shares of other J.P. Morgan Funds in order to expose the Fund to certain asset classes when the adviser believes it is appropriate.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. With respect to its fixed income allocations, the Fund may use futures contracts to manage and hedge interest rate risk associated with these investments, as well as to lengthen or shorten the duration of this portion of the portfolio. With respect to its equity and fixed income allocations, the Fund may use futures contracts to gain or reduce exposure to all or a portion of the stock or fixed income markets, respectively and for cash management. The Fund may use forward foreign currency exchange contracts to hedge or manage its foreign currency risk, as well as to gain exposure to certain currencies.

The adviser establishes the strategic and tactical allocation for the Fund and makes the day-to-day decisions concerning strategies and overall construction of the Fund. As attractive investments arise across asset classes and strategies, the adviser attempts to capture these opportunities by allocating the Fund’s assets among strategies and asset classes within pre-defined ranges.

Investment decisions within strategies and asset classes are implemented either by the portfolio managers of the Fund’s underlying strategies who select individual securities for the Fund or with the Fund’s purchase of other J.P. Morgan Funds.

The frequency with which the Fund buys and sells underlying investments will vary from year to year, depending on, but not limited to: market conditions, performance of the underlying investments, and changes in the adviser’s investment views.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

The Fund is exposed to the risks summarized below through both its direct investments and its investments in underlying funds.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

Foreign Securities and Emerging Markets Risks. Investments in foreign issuers are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. These risks are magnified in countries in “emerging markets.” Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier, more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Investments in Mutual Funds Risk. To the extent the Fund invests in underlying J.P. Morgan Funds, the Fund’s investment performance and risks are directly related to the performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by those underlying funds. Because the adviser or its affiliates provide services to and receive fees from the underlying funds, the Fund’s investments in the underlying funds benefit the adviser and/or its affiliates. In addition, the Fund may hold a significant percentage of the shares of an underlying fund. As a result, the Fund’s investments in an underlying fund may create a conflict of interest.

Income Securities Risk. Investments in income securities will change in value based on changes in interest rates and are subject to the risk that a counterparty will fail to make payments when due or default. If interest rates rise, the value of the Fund’s income securities generally drops. Certain underlying funds invest in variable and floating rate loan assignments and participations (Loans) and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than other fixed rate instruments, the value of floating rate Loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. Mortgage-related and asset-backed securities including so called “sub-prime” mortgages are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the Fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the Fund may exhibit additional volatility. Mortgage-related and asset-backed securities may decline in value, face valuation difficulties, be more volatile and/or be illiquid.

Credit Risk. Some of the Fund’s investments are subject to the risk that a counterparty will fail to make payments when due or default completely. If an issuer’s financial condition worsens, the credit quality of the issuer may deteriorate making it difficult for the Fund to sell such investments.

High Yield Securities Risk. Some of the Fund’s investments are in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed (known as junk bonds). These investments are considered to be speculative and are subject to greater risk of loss, greater sensitivity to interest rate and economic changes, valuation difficulties, and potential illiquidity.

Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund, will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivative Risk. Derivatives, including futures and foreign currency exchange contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns for the past one year, five years and ten years. The table compares that performance to the Diversified Composite Benchmark, a customized benchmark, the Morgan Stanley Capital International (MSCI) World Index (net of foreign withholding taxes), a broad-based securities market index, and the Lipper Mixed-Asset Target Allocation Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The Diversified Composite Benchmark is a composite benchmark of unmanaged indexes that corresponds to the Fund’s model allocation and that consists of MSCI World (60%) and Barclays U.S. Aggregate (40%) indexes. The performance of the Fund’s former benchmark, the S&P 500 Index, and former composite benchmark (which was composed of the S&P 500 (60%) and Barclays U.S. Aggregate (40%) indexes) is also presented in the table. The performance in the table for Class A, Class B, and Class C Shares is based on the performance of Select Class Shares prior to their inception on 3/24/03. The actual returns of Class A, Class B and Class C Shares would have been lower because each of these classes has higher expenses than Select Class Shares. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 99% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests in a focused portfolio of equity securities of large capitalization companies. Large cap companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. Typically, the Fund invests in common stocks of companies with a history of above-average growth or companies expected to enter periods of above-average growth. Although the Fund will invest primarily in equity securities of U.S. companies, it may invest up to 20% of its total assets in foreign securities, including depositary receipts.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

The Fund is non-diversified.

Investment Process: The Fund’s adviser will utilize a combination of qualitative analysis and quantitative metrics in order to seek to achieve target returns which are higher than the Fund’s benchmark while attempting to maintain a moderate risk profile. In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. The adviser looks for companies with leading competitive positions, predictable and durable business models and management that can achieve sustained growth.

The adviser may sell a security for several reasons. The adviser may sell a security due to a change in the company’s fundamentals or a change in the original reason for purchase of an investment, or if the adviser no longer considers the security to be reasonably valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Growth Investing Risk. Because growth investing attempts to identify companies that the adviser believes will experience rapid earnings growth relative to value or other types of stocks, growth stocks may also trade at higher multiples of current earnings, compared to value or other stocks, leading to inflated prices and thus potentially greater declines in value.

Derivative Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Foreign Securities Risk. Investments in foreign issuers are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, expropriation and nationalization risks, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Non-Diversified Fund Risk. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results among those issuing the securities.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past four calendar years. The table shows the average annual total returns for the past one year and life of the Fund. The table compares that performance to the Russell 1000^® Growth Index and the Lipper Large-Cap Growth Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Subsequent to the inception of the Fund on 11/30/07 until 8/6/10, the Fund did not experience any shareholder purchase and sale activity. If such shareholder activity had occurred, the Fund’s performance may have been impacted. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The performance figures in the bar chart do not reflect any deduction for the front-end sales load which is assessed on Class A Shares. If the load were reflected, the performance would have been lower.
