R2, R6 Shares | JPMorgan Small Cap Growth Fund

JPMorgan Small Cap Growth Fund

Class/Ticker: R2/JSGZX; R6/JGSMX

Currently, the Fund is publicly offered on a limited basis. (See “Purchasing Fund Shares — What does it mean that the Small Cap Growth Fund is publicly offered on a limited basis?” in the prospectus for more information.)

What is the goal of the Fund?

The Fund seeks long-term capital growth primarily by investing in a portfolio of equity securities of small-capitalization and emerging growth companies.

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 R2, R6 Shares JPMorgan Small Cap Growth Fund		Class R2	Class R6
Management Fees		0.65%	0.65%
Distribution (Rule 12b-1) Fees		0.50%	none
Other Expenses		0.54%	0.29%
Shareholder Service Fees		0.25%	none
Remainder of Other Expenses		0.29%	0.29%
Total Annual Fund Operating Expenses		1.69%	0.94%
Fee Waivers and Expense Reimbursements	[1]	(0.19%)	(0.19%)
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	[1]	1.50%	0.75%

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 R2, R6 Shares JPMorgan Small Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS R2 SHARES	153	514	900	1,982
CLASS R6 SHARES	77	281	502	1,137

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

Expense Example, No Redemption R2, R6 Shares JPMorgan Small Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS R2 SHARES	153	514	900	1,982
CLASS R6 SHARES	77	281	502	1,137

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 58% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization 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 stocks at the time of purchase. As 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 will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth.

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 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.

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 R2 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. The performance in the table for Class R2 Shares is based on the performance of Class A Shares prior to the inception of the Class R2 Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and Class A Shares. The performance in the table for the Class R6 Shares is based on the performance of the Fund’s Institutional Class and Select Class Shares prior to the inception of the Class R6 Shares. The actual returns of the Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Institutional Class and 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.

[1] 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 of Class R2 and Class R6 Shares (excluding acquired fund fees and expenses, dividend expenses relating 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 1.50% and 0.75%, respectively, of their average daily net assets.

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of large companies, including common stocks, and debt and preferred stocks which are convertible to common stock. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Value Index at the time of purchase. As of the last reconstitution of the Russell 1000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $368 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: The Fund’s adviser invests in companies whose securities are, in the adviser’s opinion, undervalued when purchased but which have the potential to increase their intrinsic value per share. 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 industry group according to their relative value.

On behalf of the Fund, the adviser then buys and sells 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
• high potential reward compared to potential risk
• temporary mispricings caused by market overreactions.

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.

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.

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).

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.

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 58% 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

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization 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 stocks at the time of purchase. As 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 will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth.

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 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.

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.

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.

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

CLASS R6 SHARES	56	185	325	734

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

CLASS R2 SHARES	132	418	726	1,599
CLASS R5 SHARES	61	201	353	795
CLASS R6 SHARES	56	185	325	734

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, at least 80% of the Fund’s Assets will be invested in the equity securities of corporations that regularly pay dividends, including common stocks and debt securities and preferred stock convertible to common stock. In implementing this strategy, the Fund invests primarily in common stock and real estate investment trusts (REITs). “Assets” means net assets, plus the amount of borrowings for investment purposes.

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 employs a fundamental bottom-up stock selection process to invest in common stock of corporations that regularly pay dividends and have favorable long-term fundamental characteristics. Because yield is a key consideration in selecting securities, the Fund may purchase stocks of companies that are out of favor in the financial community and, therefore, are selling below what the Fund’s adviser believes to be their long-term investment value. The adviser seeks to invest in 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.

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.

Smaller Cap Company Risk. Although the Fund invests primarily in securities of large cap companies, it may invest in equity investments of companies across all market capitalizations and, to the extent it does, 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.

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. Because the Class R2, Class R5 and Class R6 Shares have not operated for a full calendar year, the bar chart shows how the performance of the Fund’s Select Class Shares, which are offered in a different prospectus, has varied from year to year for the past ten calendar years. The table shows the average annual total returns for Class R2 and Class R5 Shares over the past one year, five years and ten years. The table compares the performance to the Russell 1000^® Value Index and the Lipper Equity Income 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 for the Class R2 and Class R5 Shares is based on the performance of the Select Class Shares prior to their inception. The Class R6 Shares commenced operations on 1/31/12 and, therefore, do not have a full calendar year of performance. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and Select Class Shares. The actual returns of Class R5 and Class R6 Shares would have been different than those shown because Class R5 and Class R6 Shares have different 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 Fund’s Assets will be invested in equity securities of mid cap companies, including common stocks and debt securities and preferred stocks that are convertible to common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund invests primarily in common stocks of mid cap companies which the Fund’s adviser believes are capable of achieving sustained growth. Mid cap companies are companies with market capitalizations similar to those within the universe of the Russell Midcap^® Growth Index at the time of purchase. As of the last reconstitution of the Russell Midcap Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion.

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 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.

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.

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).

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

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 144% 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

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of large companies, including common stocks, and debt and preferred stocks which are convertible to common stock. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Value Index at the time of purchase. As of the last reconstitution of the Russell 1000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $368 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: The Fund’s adviser invests in companies whose securities are, in the adviser’s opinion, undervalued when purchased but which have the potential to increase their intrinsic value per share. 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 industry group according to their relative value.

On behalf of the Fund, the adviser then buys and sells 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
• high potential reward compared to potential risk
• temporary mispricings caused by 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.

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.

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 or 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

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 R5 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 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 for the Class R5, Class R2 and Class R6 Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of Class R5 and Class R6 Shares would have been different than those shown because Class R5 and Class R6 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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 9% 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 “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a conservative growth fund, the majority of the Fund’s assets will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds, although a portion of its assets also will be invested in J.P. Morgan equity funds including international equity funds and specialty funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 70% in income securities and 30% in equity securities.

The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Conservative Growth Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so 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 the underlying funds. Because the Fund’s 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.

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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying fund decreases in value.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 38% 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 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^® Value Index stocks at the time of purchase. As of the last reconstitution of the Russell 2000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In reviewing investment opportunities for the Fund, its adviser uses a value-oriented approach. In implementing its main strategies, the Fund’s equity 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.

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.

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.

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.

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.

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 28% 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, at least 80% of the Fund’s Assets will be invested in the equity securities of large, well-established companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large, well-established companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. As of the last reconstitution of the Russell 1000 Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $540 billion. Typically, in implementing its strategy, 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.

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 approach that seeks to identify companies with positive price momentum and attractive fundamental dynamics. The adviser seeks structural disconnects which allow businesses to exceed market expectations. These disconnects may result from: demographic/cultural changes, technological advancements and/or regulatory changes. The adviser seeks to identify long-term imbalances in supply and demand.

The adviser may sell a security for several reasons. A security may be sold due to a change in the original investment thesis, if market expectations exceed the company’s potential to deliver and/or due to balance sheet deterioration. 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 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.

You could lose money investing in the Fund.

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 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. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future.

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 Mid Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	646	929	1,233	2,094
CLASS B SHARES	678	880	1,208	2,070
CLASS C SHARES	278	580	1,008	2,200

CLASS C SHARES	178	580	1,008	2,200
SELECT CLASS SHARES	96	342	608	1,368

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 70% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of mid cap companies, including common stocks and debt securities and preferred stocks that are convertible to common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund invests primarily in common stocks of mid cap companies which the Fund’s adviser believes are capable of achieving sustained growth. Mid cap companies are companies with market capitalizations similar to those within the universe of the Russell Midcap^® Growth Index at the time of purchase. As of the last reconstitution of the Russell Midcap Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion.

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 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.

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.

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.

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^® Growth Index and the Lipper Mid-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.

SELECT CLASS SHARES	45	185	337	779

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 77% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests in stocks of medium-sized and small U.S. companies that are included in the S&P SmallCap 600¹ and S&P MidCap 400¹ and which trade on the New York and American Stock Exchanges as well as over-the-counter stocks that are part of the National Market System. The Fund seeks to closely track the sector and industry weights within the combined indexes. Because the Fund uses an enhanced index strategy, not all of the stocks in the indexes are included in the Fund and the Fund’s position in an individual stock may be overweighted or underweighted when compared to the indexes. Nonetheless, the Fund, under normal circumstances, will hold 80% or more of the stocks in the combined indexes in order to closely replicate the performance of the combined indexes. The Fund seeks to achieve a correlation between the performance of its portfolio and that of the indexes of at least 0.95, without taking into account the Fund’s expenses. Perfect correlation would be 1.00.

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. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

Investment Process: Because the Fund uses an enhanced index strategy, the adviser uses a quantitative process to select the Fund’s portfolio securities. This process overweights inexpensive stocks with improving fundamental characteristics and underweights expensive stocks that have deteriorating fundamental characteristics. A previously attractive stock is pared back or sold when the combined perspective on valuation and fundamentals is no longer favorable.

The Fund’s Main Investment Risks

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.

Index Investing Risk. The Fund attempts to track the performance of a market capitalization-weighted combination of the S&P Small Cap 600 and the S&P MidCap 400. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. There is also the risk that the Fund’s performance may not correlate with the performance of the index.

Smaller Cap Company Risk. Investments in mid cap and 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 interest. 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 creditworthiness 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.

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 Fund’s Assets will be invested in the equity securities of corporations that regularly pay dividends, including common stocks and debt securities and preferred stock convertible to common stock. In implementing this strategy, the Fund invests primarily in common stock and real estate investment trusts (REITs). “Assets” means net assets, plus the amount of borrowings for investment purposes.

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 employs a fundamental bottom- up stock selection process to invest in common stock of corporations that regularly pay dividends and have favorable long-term fundamental characteristics. Because yield is a key consideration in selecting securities, the Fund may purchase stocks of companies that are out of favor in the financial community and, therefore, are selling below what the Fund’s adviser believes to be their long-term investment value. The adviser seeks to invest in 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

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.

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.

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.

Smaller Cap Company Risk. Although the Fund invests primarily in securities of large cap companies, it may invest in equity investments of companies across all market capitalizations and, to the extent it does, 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.

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 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 77% 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 invests in stocks of medium-sized and small U.S. companies that are included in the S&P SmallCap 600¹ and S&P MidCap 400¹ and which trade on the New York and American Stock Exchanges as well as over-the-counter stocks that are part of the National Market System. The Fund seeks to closely track the sector and industry weights within the combined indexes. Because the Fund uses an enhanced index strategy, not all of the stocks in the indexes are included in the Fund and the Fund’s position in an individual stock may be overweighted or underweighted when compared to the indexes. Nonetheless, the Fund, under normal circumstances, will hold 80% or more of the stocks in the combined indexes in order to closely replicate the performance of the combined indexes. The Fund seeks to achieve a correlation between the performance of its portfolio and that of the indexes of at least 0.95, without taking into account the Fund’s expenses. Perfect correlation would be 1.00.

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. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

Investment Process: Because the Fund uses an enhanced index strategy, the adviser uses a quantitative process to select the Fund’s portfolio securities. This process overweights inexpensive stocks with improving fundamental characteristics and underweights expensive stocks that have deteriorating fundamental characteristics. A previously attractive stock is pared back or sold when the combined perspective on valuation and fundamentals is no longer favorable.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Index Investing Risk. The Fund attempts to track the performance of a market capitalization-weighted combination of the S&P Small Cap 600 and the S&P MidCap 400. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. There is also the risk that the Fund’s performance may not correlate with the performance of the index.

Smaller Cap Company Risk. Investments in mid cap and 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 interest. 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 creditworthiness 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. 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.

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 R2 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 S&P 1000 Index and the Lipper Small-Cap Core Funds Index and Lipper Mid-Cap Core Funds Index, both of which are indexes based on the total returns of certain small cap and mid cap mutual funds within small cap and mid cap fund categories, respectively, as determined by Lipper. Unlike the other index, the Lipper indexes include the expenses of the mutual funds included in the indexes. The performance for Class R2 Shares is based on the performance of Select Class Shares prior to the inception of the Class R2 Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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:

Expense Example A, B, C, Select Shares JPMorgan Investor Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	595	950	1,329	2,390
CLASS B SHARES	727	1,000	1,400	2,449
CLASS C SHARES	327	700	1,200	2,575
SELECT CLASS SHARES	126	446	790	1,758

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

Expense Example, No Redemption A, B, C, Select Shares JPMorgan Investor Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	595	950	1,329	2,390
CLASS B SHARES	227	700	1,200	2,449
CLASS C SHARES	227	700	1,200	2,575
SELECT CLASS SHARES	126	446	790	1,758

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 6% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a growth fund, the majority of the Fund’s assets will be invested in J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds, although a portion of its assets also will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 90% in equity securities and 10% in income securities. The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Growth Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so the Fund’s investment performance and risks are directly related to performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying 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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Smaller Companies Risk. Some of the underlying funds invest in securities of smaller companies which may be riskier, more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Russell 3000 Index and the Barclays U.S. Intermediate Aggregate Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, 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 indexes, 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.

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, at least 80% of the Fund’s Assets will be invested in the equity securities of corporations that regularly pay dividends, including common stocks and debt securities and preferred stock convertible to common stock. In implementing this strategy, the Fund invests primarily in common stock and real estate investment trusts (REITs). “Assets” means net assets, plus the amount of borrowings for investment purposes.

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 employs a fundamental bottom- up stock selection process to invest in common stock of corporations that regularly pay dividends and have favorable long-term fundamental characteristics. Because yield is a key consideration in selecting securities, the Fund may purchase stocks of companies that are out of favor in the financial community and, therefore, are selling below what the Fund’s adviser believes to be their long-term investment value. The adviser seeks to invest in 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.

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.

Smaller Cap Company Risk. Although the Fund invests primarily in securities of large cap companies, it may invest in equity investments of companies across all market capitalizations and, to the extent it does, 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.

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 28% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the equity securities of large, well-established companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large, well-established companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. As of the last reconstitution of the Russell 1000 Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $540 billion. Typically, in implementing its strategy, 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.

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 approach that seeks to identify companies with positive price momentum and attractive fundamental dynamics. The adviser seeks structural disconnects which allow businesses to exceed market expectations. These disconnects may result from: demographic/cultural changes, technological advancements and/or regulatory changes. The adviser seeks to identify long-term imbalances in supply and demand.

The adviser may sell a security for several reasons. A security may be sold due to a change in the original investment thesis, if market expectations exceed the company’s potential to deliver and/or due to balance sheet deterioration. 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.

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 9% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a conservative growth fund, the majority of the Fund’s assets will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds, although a portion of its assets also will be invested in J.P. Morgan equity funds including international equity funds and specialty funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 70% in income securities and 30% in equity securities.

The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Conservative Growth Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so 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 the underlying funds. Because the Fund’s 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.

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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying fund decreases in value.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Barclays U.S. Intermediate Aggregate Index and the Russell 3000 Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, and the Lipper Mixed-Asset Target Allocation Conservative 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 indexes, 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.

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 38% 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^® Value Index stocks at the time of purchase. As of the last reconstitution of the Russell 2000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In reviewing investment opportunities for the Fund, its adviser uses a value-oriented approach. In implementing its main strategies, the Fund’s equity 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.

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.

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 Class R6 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^® Value Index and Lipper Small-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 for the Class R6, Class R5 and Class R2 Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of Class R6 and Class R5 Shares would have been different than those shown because Class R6 and Class R5 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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

The Fund attempts to neutralize exposure to general domestic market risk by primarily investing in common stocks that the Fund’s adviser considers to be attractive and ‘short selling’ stocks that the adviser considers to be unattractive. The Fund uses a multi-style approach, meaning that it may invest across different industries, sectors and capitalization levels targeting both value-and growth-oriented domestic companies. The Fund intends to maintain approximately equal value exposure in its long and short positions in order to offset the effects on its performance resulting from general domestic stock market movements or sector swings. By using this strategy, the Fund seeks to generate returns independent of the direction of the stock market.

When the Fund makes a short sale, the Fund borrows the security in order to settle the sale and buys the security at a later date to return to the lender. The Fund must maintain collateral at least equal to the current market value of the security sold short.

Investment Process: In determining whether a stock is attractive or unattractive, the adviser uses a proprietary stock selection model that collects quantitative and fundamental investment data designed to evaluate the relative attractiveness of stocks. The stock selection model considers valuation factors such as discounted cash flows and price-to-book values, as well as account data concerning an issuer’s fundamentals. The Fund seeks to enhance return by purchasing long positions in stocks that are ranked the highest by the model and selling short stocks that are ranked the lowest.

The Fund’s strategy is to be sector neutral meaning that both the long and short positions will have approximately the same weight in the market sectors in which the Fund invests. However, the stock selection model may result in the Fund’s long and short positions being overweighted in different industries within a sector.

The Fund may achieve a gain if the securities in its long portfolio outperform the securities in its short portfolio, each taken as a whole. Conversely, it is expected that the Fund will incur a loss if the securities in its short portfolio outperform the securities in its long portfolio.

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.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting a 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.

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.

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 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.

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.

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 over the past one year, five years and the life of the Fund. The table compares that performance to the BofA Merrill Lynch 3-Month US Treasury Bill Index and the Lipper Equity Market-Neutral Funds Average, an index based on the total returns of all 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.

An investment in the Fund is different from an investment in 3-month U.S. Treasury bills because, among other things, Treasury bills are backed by the full faith and credit of the U.S. Government. Treasury bills have a fixed rate of return, investors in Treasury bills do not risk losing their investment, and an investment in the Fund is more volatile than an investment in Treasury bills.

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 70% 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

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of mid cap companies, including common stocks and debt securities and preferred stocks that are convertible to common stocks. “Assets” means net assets, plus the amount of borrowings for investment purposes. In implementing its main strategies, the Fund invests primarily in common stocks of mid cap companies which the Fund’s adviser believes are capable of achieving sustained growth. Mid cap companies are companies with market capitalizations similar to those within the universe of the Russell Midcap^® Growth Index at the time of purchase. As of the last reconstitution of the Russell Midcap Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion.

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 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.

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.

Growth Investing Risk. Because 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.

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 Class R2 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^® Growth Index and the Lipper Mid-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 R2, Class R5 and Class R6 Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of Class R5 and Class R6 Shares would be different than those shown because Class R5 and Class R6 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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 9% 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 “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a balanced fund, approximately half of the Fund’s assets will be allocated to J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds and approximately half will be invested in J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 50% in income securities and 50% in equity securities.The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Balanced Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so 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 the underlying funds. Because the Fund’s 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying 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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Barclays U.S. Intermediate Aggregate Index and the Russell 3000 Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, and the Lipper Mixed Asset-Target Allocation Moderate 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 indexes, 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.

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 7% 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

The Fund invests in stocks included in the S&P 500 Index¹ and also may invest in stock index futures. The Fund’s adviser attempts to track the performance of the S&P 500 Index to achieve a correlation of at least 0.95 between the performance of the Fund and that of the S&P 500 Index without taking into account the Fund’s expenses. Perfect correlation would be 1.00.

The percentage of a stock that the Fund holds will be approximately the same percentage that the stock represents in the S&P 500 Index. The adviser generally picks stocks in the order of their weightings in the S&P 500 Index, starting with the heaviest weighted stock. Under normal circumstances, at least 80% of the Fund’s Assets will be invested in stocks of companies included in the index or indices identified by the Fund and in derivative instruments that provide exposure to stocks of such companies. “Assets” means net assets, plus the amount of borrowings for investment purposes.

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. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

1 “S&P 500” is a registered service mark of Standard & Poor’s Corporation, which does not sponsor and is in no way affiliated with the Fund.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Index Investing Risk. The Fund is not actively managed and is designed to track the performance of the S&P 500 Index. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. There is also the risk that the Fund’s performance may not correlate with the performance of the index.

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.

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 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 the performance to the S&P 500 Index and the Lipper S&P 500 Objective 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.

JPMorgan Large Cap Value Fund

Class/Ticker: R2/JLVZX; R5/JLVRX; R6/JLVMX

What is the goal of the Fund?

The Fund seeks capital appreciation with the incidental goal of achieving current income by investing primarily in equity securities.

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.

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:

CLASS R2 SHARES	122	404	708	1,569
CLASS R5 SHARES	61	194	339	761
CLASS R6 SHARES	56	178	312	700

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

Expense Example, No Redemption R2, R5, R6 Shares JPMorgan Large Cap Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS R2 SHARES	122	404	708	1,569
CLASS R5 SHARES	61	194	339	761
CLASS R6 SHARES	56	178	312	700

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 144% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of large companies, including common stocks, and debt and preferred stocks which are convertible to common stock. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Value Index at the time of purchase. As of the last reconstitution of the Russell 1000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $368 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: The Fund’s adviser invests in companies whose securities are, in the adviser’s opinion, undervalued when purchased but which have the potential to increase their intrinsic value per share. 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 industry group according to their relative value.

On behalf of the Fund, the adviser then buys and sells 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
• high potential reward compared to potential risk
• temporary mispricings caused by 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.

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.

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 or 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 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 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 for the Class R5, Class R2 and Class R6 Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of Class R5 and Class R6 Shares would have been different than those shown because Class R5 and Class R6 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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

The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a growth fund, the majority of the Fund’s assets will be invested in J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds, although a portion of its assets also will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 90% in equity securities and 10% in income securities. The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Growth Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so the Fund’s investment performance and risks are directly related to performance and risks of the underlying funds. Shareholders will indirectly bear the expenses charged by the underlying funds. Because the Fund’s 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying 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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Smaller Companies Risk. Some of the underlying funds invest in securities of smaller companies which may be riskier, more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Russell 3000 Index and the Barclays U.S. Intermediate Aggregate Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, 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 indexes, 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:

SELECT CLASS SHARES	127	437	769	1,708

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 9% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a balanced fund, approximately half of the Fund’s assets will be allocated to J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds and approximately half will be invested in J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 50% in income securities and 50% in equity securities.The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Balanced Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so 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 the underlying funds. Because the Fund’s 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying 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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Barclays U.S. Intermediate Aggregate Index and the Russell 3000 Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, and the Lipper Mixed Asset-Target Allocation Moderate 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 indexes, 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 Large Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	632	869	1,125	1,856
CLASS B SHARES	664	819	1,097	1,828
CLASS C SHARES	264	519	897	1,961
SELECT CLASS SHARES	93	290	504	1,120

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

CLASS C SHARES	164	519	897	1,961
SELECT CLASS SHARES	93	290	504	1,120

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, at least 80% of the Fund’s Assets will be invested in the equity securities of large, well-established companies. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large, well-established companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Growth Index at the time of purchase. As of the last reconstitution of the Russell 1000 Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $540 billion. Typically, in implementing its strategy, 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.

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 approach that seeks to identify companies with positive price momentum and attractive fundamental dynamics. The adviser seeks structural disconnects which allow businesses to exceed market expectations. These disconnects may result from: demographic/cultural changes, technological advancements and/or regulatory changes. The adviser seeks to identify long-term imbalances in supply and demand.

The adviser may sell a security for several reasons. A security may be sold due to a change in the original investment thesis, if market expectations exceed the company’s potential to deliver and/or due to balance sheet deterioration. 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.

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.

SELECT CLASS SHARES	133	460	809	1,795

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 11% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a growth and income fund, the majority of the Fund’s assets will be invested in J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds while a moderate portion will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 70% in equity securities and 30% in income securities. The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Growth & Income Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so 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 the underlying funds. Because the Fund’s 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying 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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Smaller Companies Risk. Some of the underlying funds invest in securities of smaller companies which may be riskier, more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Russell 3000 Index and the Barclays U.S. Intermediate Aggregate Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, 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 indexes, 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.

R2 Shares | JPMorgan Market Expansion Index Fund

JPMorgan Market Expansion Index Fund

Class/Ticker: R2/JMEZX

What is the goal of the Fund?

The Fund seeks to provide a return which substantially duplicates the price and yield performance of domestically traded common stocks in the small- and mid-capitalization equity markets, as represented by a market capitalization weighted combination of the Standard & Poor’s SmallCap 600 Index (S&P SmallCap 600) and the Standard & Poor’s MidCap 400 Index (S&P MidCap 400).

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		R2 Shares JPMorgan Market Expansion Index Fund CLASS R2 SHARES
Management Fees		0.25%
Distribution (Rule 12b-1) Fees		0.50%
Other Expenses		0.39%
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.

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 77% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests in stocks of medium-sized and small U.S. companies that are included in the S&P SmallCap 600¹ and S&P MidCap 400¹ and which trade on the New York and American Stock Exchanges as well as over-the-counter stocks that are part of the National Market System. The Fund seeks to closely track the sector and industry weights within the combined indexes. Because the Fund uses an enhanced index strategy, not all of the stocks in the indexes are included in the Fund and the Fund’s position in an individual stock may be overweighted or underweighted when compared to the indexes. Nonetheless, the Fund, under normal circumstances, will hold 80% or more of the stocks in the combined indexes in order to closely replicate the performance of the combined indexes. The Fund seeks to achieve a correlation between the performance of its portfolio and that of the indexes of at least 0.95, without taking into account the Fund’s expenses. Perfect correlation would be 1.00.

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. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

Investment Process: Because the Fund uses an enhanced index strategy, the adviser uses a quantitative process to select the Fund’s portfolio securities. This process overweights inexpensive stocks with improving fundamental characteristics and underweights expensive stocks that have deteriorating fundamental characteristics. A previously attractive stock is pared back or sold when the combined perspective on valuation and fundamentals is no longer favorable.

The Fund’s Main Investment Risks

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.

Index Investing Risk. The Fund attempts to track the performance of a market capitalization-weighted combination of the S&P Small Cap 600 and the S&P MidCap 400. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. There is also the risk that the Fund’s performance may not correlate with the performance of the index.

Smaller Cap Company Risk. Investments in mid cap and 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 interest. 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 creditworthiness 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. 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 R2 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 S&P 1000 Index and the Lipper Small-Cap Core Funds Index and Lipper Mid-Cap Core Funds Index, both of which are indexes based on the total returns of certain small cap and mid cap mutual funds within small cap and mid cap fund categories, respectively, as determined by Lipper. Unlike the other index, the Lipper indexes include the expenses of the mutual funds included in the indexes. The performance for Class R2 Shares is based on the performance of Select Class Shares prior to the inception of the Class R2 Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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.

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^® Value Index stocks at the time of purchase. As of the last reconstitution of the Russell 2000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In reviewing investment opportunities for the Fund, its adviser uses a value-oriented approach. In implementing its main strategies, the Fund’s equity 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

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.

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.

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.

Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance for the Class R6, Class R5 and Class R2 Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of Class R6 and Class R5 Shares would have been different than those shown because Class R6 and Class R5 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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.

What is the goal of the Fund?

The Fund seeks long-term capital growth primarily by investing in a portfolio of equity securities of small-capitalization and emerging growth companies.

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, B, C, Select Shares JPMorgan Small Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	646	939	1,253	2,143
CLASS B SHARES	678	891	1,229	2,119
CLASS C SHARES	278	591	1,029	2,249
SELECT CLASS SHARES	102	359	636	1,426

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

Expense Example, No Redemption A, B, C, Select Shares JPMorgan Small Cap Growth Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	646	939	1,253	2,143
CLASS B SHARES	178	591	1,029	2,119
CLASS C SHARES	178	591	1,029	2,249
SELECT CLASS SHARES	102	359	636	1,426

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 58% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization 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 stocks at the time of purchase. As 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 will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth.

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 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.

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^® 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.

As of the last reconstitution of the Russell 1000 Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $540 billion. Typically, in implementing its strategy, 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.

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 approach that seeks to identify companies with positive price momentum and attractive fundamental dynamics. The adviser seeks structural disconnects which allow businesses to exceed market expectations. These disconnects may result from: demographic/cultural changes, technological advancements and/or regulatory changes. The adviser seeks to identify long-term imbalances in supply and demand.

The adviser may sell a security for several reasons. A security may be sold due to a change in the original investment thesis, if market expectations exceed the company’s potential to deliver and/or due to balance sheet deterioration. 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.

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.

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 R2 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 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 for Class R2, Class R5 and Class R6 Shares is based on the performance of Select Class Shares prior to their inception. The actual returns of Class R5 and Class R6 Shares would have been different than those shown because Class R5 and Class R6 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a “Fund of Funds.” The Fund’s main investment strategy is to invest in other J.P. Morgan Funds (underlying funds). Because this is a growth and income fund, the majority of the Fund’s assets will be invested in J.P. Morgan equity funds including J.P. Morgan international equity funds and J.P. Morgan specialty funds while a moderate portion will be allocated to J.P. Morgan income funds and J.P. Morgan money market funds. J.P. Morgan specialty funds include funds that use market neutral strategies or that have exposure to alternative equity asset classes such as real estate investment trusts (REITs) or commodities. Generally, the Fund’s allocation strategy is to achieve a long-term risk/return profile similar to a fund that invests 70% in equity securities and 30% in income securities. The Fund’s adviser, J.P. Morgan Investment Management Inc. (JPMIM or the adviser) allocates the Fund’s investments in the underlying funds based on an evaluation of three components: fund selection, tactical asset allocation and strategic asset allocation. The adviser determines the strategic weight for each asset class represented by the underlying funds by using three to five-year and 10 to 15-year outlooks. Taking a long term approach, the adviser focuses on making investments that it believes will perform well over time while maintaining a level of volatility similar to the Investor Growth & Income Composite Benchmark and its Lipper peer group.

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.

Investments in Mutual Funds Risk. The Fund invests in other J.P. Morgan Funds as a primary strategy, so 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 the underlying funds. Because the Fund’s 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.

Equity Securities Risk. Certain underlying funds invest in equity securities (such as stocks) that are more volatile and carry more risks than some other forms of investment. The price of equity securities may rise or fall because of economic or political changes 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 underlying fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the underlying fund’s securities goes down, the Fund’s investment in the underlying 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.

Income Securities Risk. Certain underlying funds invest in income securities that 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 rates rise, the value of these investments drops. Certain underlying funds invest in mortgage-related and asset-backed securities including so-called “sub-prime” mortgages that are subject to certain other risks. The value of these securities will be influenced by the factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. These securities are also subject to prepayment and call risk. In periods of declining interest rates, the underlying fund may be subject to contraction risk which is the risk that borrowers will increase the rate at which they prepay the maturity value of mortgages and other obligations. When mortgages and other obligations are prepaid and when securities are called, the underlying 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 dividend and yield. In periods of rising interest rates, the underlying fund may be subject to extension risk which is the risk that the expected maturity of an obligation will lengthen in duration due to a decrease in prepayments. As a result, in certain interest rate environments, the underlying fund may exhibit additional volatility.

Index Funds Risk. Index funds are not actively managed and are designed to track the performance and holdings of a specified index. Securities may be purchased, held and sold by an index fund at times when an actively managed fund would not do so. There is also the risk that the underlying fund’s performance may not correlate with the performance of the index.

Foreign Securities and Emerging Markets Risk. Underlying funds that invest in foreign currencies, foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, greater volatility, civil conflicts and war, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, expropriation and nationalization risks, liquidity risks, 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.

High Yield Securities Risk. Some of the underlying funds invest in securities and instruments that are issued by companies that are highly leveraged, less creditworthy or financially distressed. These investments (known as junk bonds) 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.

Convertible Securities Risk. Some of the underlying funds invest in convertible securities. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities.

Strategy Risk. A primary risk of some of the underlying funds is to invest in common stock considered to be attractive and to sell short securities considered to be unattractive. This strategy involves complex securities transactions that require the underlying fund to borrow securities. The underlying fund may not be able to borrow a security it wishes to sell short or may have to purchase a borrowed security in the market to return it to the lender at a disadvantageous time or price. Losses on short sales are potentially unlimited because there is no upward limit on the price a borrowed security could attain.

Smaller Companies Risk. Some of the underlying funds invest in securities of smaller companies which may be riskier, more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies.

Commodity Risk. Certain underlying funds have exposure to commodities. Exposure to commodities, commodity-related securities and derivatives may subject an underlying fund to greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of commodity-linked investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. In addition, to the extent that an underlying fund gains exposure to an asset through synthetic replication by investing in commodity-linked investments rather than directly in the asset, it may not have a claim on the applicable underlying asset and will be subject to enhanced counterparty risk.

Derivatives Risk. The underlying funds may use derivatives. Derivatives may be riskier than other investments because they may be sensitive to changes in economic and market conditions and could result in losses that significantly exceed the original investment. Many derivatives create leverage thereby causing the underlying fund to be more volatile than they would be if they had not used derivatives. Derivatives also expose the underlying funds to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligation), including credit risk of the derivative 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.

Inflation-Managed Strategy Risk. The underlying funds may use inflation-managed strategies including using swaps that are based on the Consumer Price Index for all Urban Consumers (CPI-U) in combination with a core portfolio of fixed income securities to create the equivalent of a portfolio of inflation-protected fixed income securities. There is no guarantee that the use of derivatives and debt securities will mimic a portfolio of inflation-protected bonds or reflect the actual rate of inflation. In addition, some of the underlying funds may make direct investments in inflation-protected securities. Unlike conventional bonds, the principal or interest of inflation-protected securities such as Treasury Inflation Protected Securities (TIPS) is adjusted periodically to a specified rate of inflation (e.g., CPI-U). There can be no assurance that the inflation index used will accurately measure the actual rate of inflation. These securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index.

Real Estate Securities Risk. Certain underlying funds are highly concentrated in real estate securities, including REITs. These securities are subject to the same risks as direct investments in real estate and mortgages, which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy, environmental factors and, in the case of mortgages, credit risk, prepayment risk and extension risk. In addition, investments in REITs are subject to risks associated with the management skill and credit worthiness of the issuer and underlying funds will indirectly bear their proportionate share of expenses, including management fees, paid by each REIT in which they invest in addition to the expenses of the underlying funds. Certain underlying funds are highly concentrated in real estate securities, including REITS.

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 or occur in times of overall market turmoil or declining prices.

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 for the past one year, five years, and ten years. The table compares that performance to the Russell 3000 Index and the Barclays U.S. Intermediate Aggregate Index, both broad-based securities market indexes, and the composite benchmark of unmanaged indexes that correspond to the Fund’s model allocation, 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 indexes, 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:

CLASS C SHARES	291	591	1,016	2,201
SELECT CLASS SHARES	101	345	609	1,362

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

Expense Example, No Redemption A, B, C, Select Shares JPMorgan Intrepid Mid Cap Fund (USD $)	1 Year	3 Years	5 Years	10 Years

CLASS C SHARES	191	591	1,016	2,201
SELECT CLASS SHARES	101	345	609	1,362

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 51% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in common and preferred stocks, rights, warrants, convertible securities and other 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 similar 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).

The Fund invests primarily in a broad portfolio of common stocks of companies within the Russell Midcap Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative outperformance. 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 that 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 listed above 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. 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.

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 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.

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 C SHARES	248	482	840	1,847
SELECT CLASS SHARES	82	258	449	1,001

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

CLASS B SHARES	148	484	844	1,720
CLASS C SHARES	148	482	840	1,847
SELECT CLASS SHARES	82	258	449	1,001

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 144% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in equity securities of large companies, including common stocks, and debt and preferred stocks which are convertible to common stock. “Assets” means net assets, plus the amount of borrowings for investment purposes. Large companies are companies with market capitalizations equal to those within the universe of the Russell 1000^® Value Index at the time of purchase. As of the last reconstitution of the Russell 1000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $368 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: The Fund’s adviser invests in companies whose securities are, in the adviser’s opinion, undervalued when purchased but which have the potential to increase their intrinsic value per share. 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 industry group according to their relative value.

On behalf of the Fund, the adviser then buys and sells 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
• high potential reward compared to potential risk
• temporary mispricings caused by 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.

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.

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, at least 80% of the Fund’s Assets will be invested in the equity securities of corporations that regularly pay dividends, including common stocks and debt securities and preferred stock convertible to common stock. In implementing this strategy, the Fund invests primarily in common stock and real estate investment trusts (REITs). “Assets” means net assets, plus the amount of borrowings for investment purposes.

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 employs a fundamental bottom-up stock selection process to invest in common stock of corporations that regularly pay dividends and have favorable long-term fundamental characteristics. Because yield is a key consideration in selecting securities, the Fund may purchase stocks of companies that are out of favor in the financial community and, therefore, are selling below what the Fund’s adviser believes to be their long-term investment value. The adviser seeks to invest in 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.

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.

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.

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.

Smaller Cap Company Risk. Although the Fund invests primarily in securities of large cap companies, it may invest in equity investments of companies across all market capitalizations and, to the extent it does, 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.

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.

This section provides some indication of the risks of investing in the Fund. Because the Class R2, Class R5 and Class R6 Shares have not operated for a full calendar year, the bar chart shows how the performance of the Fund’s Select Class Shares, which are offered in a different prospectus, has varied from year to year for the past ten calendar years. The table shows the average annual total returns for Class R2 and Class R5 Shares over the past one year, five years and ten years. The table compares the performance to the Russell 1000^® Value Index and the Lipper Equity Income 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 for the Class R2 and Class R5 Shares is based on the performance of the Select Class Shares prior to their inception. The Class R6 Shares commenced operations on 1/31/12 and, therefore, do not have a full calendar year of performance. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and Select Class Shares. The actual returns of Class R5 and Class R6 Shares would have been different than those shown because Class R5 and Class R6 Shares have different 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

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 77% 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

The Fund invests in stocks of medium-sized and small U.S. companies that are included in the S&P SmallCap 600¹ and S&P MidCap 400¹ and which trade on the New York and American Stock Exchanges as well as over-the-counter stocks that are part of the National Market System. The Fund seeks to closely track the sector and industry weights within the combined indexes. Because the Fund uses an enhanced index strategy, not all of the stocks in the indexes are included in the Fund and the Fund’s position in an individual stock may be overweighted or underweighted when compared to the indexes. Nonetheless, the Fund, under normal circumstances, will hold 80% or more of the stocks in the combined indexes in order to closely replicate the performance of the combined indexes. The Fund seeks to achieve a correlation between the performance of its portfolio and that of the indexes of at least 0.95, without taking into account the Fund’s expenses. Perfect correlation would be 1.00.

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. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

Investment Process: Because the Fund uses an enhanced index strategy, the adviser uses a quantitative process to select the Fund’s portfolio securities. This process overweights inexpensive stocks with improving fundamental characteristics and underweights expensive stocks that have deteriorating fundamental characteristics. A previously attractive stock is pared back or sold when the combined perspective on valuation and fundamentals is no longer favorable.

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Index Investing Risk. The Fund attempts to track the performance of a market capitalization-weighted combination of the S&P Small Cap 600 and the S&P MidCap 400. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. There is also the risk that the Fund’s performance may not correlate with the performance of the index.

Smaller Cap Company Risk. Investments in mid cap and 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 interest. 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 creditworthiness 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.

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 S&P 1000 Index and the Lipper Small-Cap Core Funds Index and Lipper Mid-Cap Core Funds Index, both of which are indexes based on the total returns of certain small cap and mid cap mutual funds within small cap and mid cap fund categories, respectively, as determined by Lipper. Unlike the other index, the Lipper indexes include the expenses of the mutual funds included in the indexes. 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

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 51% 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

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in common and preferred stocks, rights, warrants, convertible securities and other 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 similar 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).

The Fund invests primarily in a broad portfolio of common stocks of companies within the Russell Midcap Index that the adviser believes have characteristics such as attractive valuations, high quality and/or strong momentum that should lead to relative outperformance. 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 that 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 listed above 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. 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.

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 58% 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, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization 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 stocks at the time of purchase. As 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 will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth.

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 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.

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.

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.

You could lose money investing in the Fund.

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 Institutional 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 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. The performance for the Institutional Class Shares prior to their inception is based on the performance of the Select Class Shares. The actual returns of Institutional Class Shares would have been different than those shown because Institutional Class Shares have different 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.

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 Equity Index Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	569	762	972	1,577
CLASS B SHARES	622	732	964	1,567
CLASS C SHARES	222	432	764	1,704
SELECT CLASS SHARES	20	171	336	812

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

Expense Example, No Redemption A, B, C, Select Shares JPMorgan Equity Index Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	569	762	972	1,577
CLASS B SHARES	122	432	764	1,567
CLASS C SHARES	122	432	764	1,704
SELECT CLASS SHARES	20	171	336	812

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 7% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests in stocks included in the S&P 500 Index¹ and also may invest in stock index futures. The Fund’s adviser attempts to track the performance of the S&P 500 Index to achieve a correlation of at least 0.95 between the performance of the Fund and that of the S&P 500 Index without taking into account the Fund’s expenses. Perfect correlation would be 1.00.

The percentage of a stock that the Fund holds will be approximately the same percentage that the stock represents in the S&P 500 Index. The adviser generally picks stocks in the order of their weightings in the S&P 500 Index, starting with the heaviest weighted stock. Under normal circumstances, at least 80% of the Fund’s Assets will be invested in stocks of companies included in the index or indices identified by the Fund and in derivative instruments that provide exposure to stocks of such companies. “Assets” means net assets, plus the amount of borrowings for investment purposes.

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. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

The Fund’s Main Investment Risks

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.

Index Investing Risk. The Fund is not actively managed and is designed to track the performance of the S&P 500 Index. Therefore, securities may be purchased, retained and sold by the Fund at times when an actively managed fund would not do so. If the value of securities that are heavily weighted in the index changes, you can expect a greater risk of loss than would be the case if the Fund were not fully invested in such securities. There is also the risk that the Fund’s performance may not correlate with the performance of the index.

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.

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 the performance to the S&P 500 Index and the Lipper S&P 500 Objective 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.

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	293	936	1,604	3,389

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 316% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund attempts to neutralize exposure to general domestic market risk by primarily investing in common stocks that the Fund’s adviser considers to be attractive and ‘short selling’ stocks that the adviser considers to be unattractive. The Fund uses a multi-style approach, meaning that it may invest across different industries, sectors and capitalization levels targeting both value-and growth-oriented domestic companies. The Fund intends to maintain approximately equal value exposure in its long and short positions in order to offset the effects on its performance resulting from general domestic stock market movements or sector swings. By using this strategy, the Fund seeks to generate returns independent of the direction of the stock market.

When the Fund makes a short sale, the Fund borrows the security in order to settle the sale and buys the security at a later date to return to the lender. The Fund must maintain collateral at least equal to the current market value of the security sold short.

Investment Process: In determining whether a stock is attractive or unattractive, the adviser uses a proprietary stock selection model that collects quantitative and fundamental investment data designed to evaluate the relative attractiveness of stocks. The stock selection model considers valuation factors such as discounted cash flows and price-to-book values, as well as account data concerning an issuer’s fundamentals. The Fund seeks to enhance return by purchasing long positions in stocks that are ranked the highest by the model and selling short stocks that are ranked the lowest.

The Fund’s strategy is to be sector neutral meaning that both the long and short positions will have approximately the same weight in the market sectors in which the Fund invests. However, the stock selection model may result in the Fund’s long and short positions being overweighted in different industries within a sector.

The Fund may achieve a gain if the securities in its long portfolio outperform the securities in its short portfolio, each taken as a whole. Conversely, it is expected that the Fund will incur a loss if the securities in its short portfolio outperform the securities in its long portfolio.

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.

Strategy Risk. There is no guarantee that the use of long and short positions will succeed in limiting a 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.

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.

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 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.

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 over the past one year, five years and the life of the Fund. The table compares that performance to the BofA Merrill Lynch 3-Month US Treasury Bill Index and the Lipper Equity Market-Neutral Funds Average, an index based on the total returns of all 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.

An investment in the Fund is different from an investment in 3-month U.S. Treasury bills because, among other things, Treasury bills are backed by the full faith and credit of the U.S. Government. Treasury bills have a fixed rate of return, investors in Treasury bills do not risk losing their investment, and an investment in the Fund is more volatile than an investment in Treasury bills.

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 58% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization 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 stocks at the time of purchase. As 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 will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth.

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 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.

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 Institutional 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 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. The performance for the Institutional Class Shares prior to their inception is based on the performance of the Select Class Shares. The actual returns of Institutional Class Shares would have been different than those shown because Institutional Class Shares have different expenses than Select Class Shares.

In implementing its main strategies, the Fund invests primarily in common stocks of mid cap companies which the Fund’s adviser believes are capable of achieving sustained growth. Mid cap companies are companies with market capitalizations similar to those within the universe of the Russell Midcap^® Growth Index at the time of purchase. As of the last reconstitution of the Russell Midcap Growth Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $1.4 billion to $17.4 billion.

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 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.

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.

Growth Investing Risk. Because 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.

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 R2 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^® Growth Index and the Lipper Mid-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 R2, Class R5 and Class R6 Shares is based on the performance of the Select Class Shares prior to their inception. The actual returns of Class R5 and Class R6 Shares would be different than those shown because Class R5 and Class R6 Shares have different expenses than Select Class Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and 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 58% 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, at least 80% of the Fund’s Assets will be invested in the securities of small capitalization 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 stocks at the time of purchase. As 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 will invest primarily in common stocks. Typically, the Fund invests in securities of companies with a history of above-average growth, as well as companies expected to have above-average growth.

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 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.

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.

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.

The performance in the table for Class R2 Shares is based on the performance of Class A Shares prior to the inception of the Class R2 Shares. Prior class performance for Class R2 Shares has been adjusted to reflect differences in expenses between Class R2 Shares and Class A Shares. The performance in the table for the Class R6 Shares is based on the performance of the Fund’s Institutional Class and Select Class Shares prior to the inception of the Class R6 Shares. The actual returns of the Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Institutional Class and Select Class Shares.

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 Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	647	936	1,246	2,125
CLASS B SHARES	690	898	1,232	2,110
CLASS C SHARES	290	598	1,032	2,239
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 Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	647	936	1,246	2,125
CLASS B SHARES	190	598	1,032	2,110
CLASS C SHARES	190	598	1,032	2,239
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 38% 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^® Value Index stocks at the time of purchase. As of the last reconstitution of the Russell 2000 Value Index on June 22, 2012, the market capitalizations of the companies in the index ranged from $101 million to $2.6 billion. In reviewing investment opportunities for the Fund, its adviser uses a value-oriented approach. In implementing its main strategies, the Fund’s equity 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.

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.

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.
