INVESCO Technology Fund

Fund Summaries - INVESCO TECHNOLOGY FUND

Investment Objective(s)

The Fund’s investment objective is long-term growth of capital.

Fees and Expenses of the Fund

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	INVESCO Technology Fund Class R5
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, whichever is less)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	INVESCO Technology Fund Class R5
Management Fees	0.69%
Distribution and/or Service (12b-1) Fees	none
Other Expenses	0.20%
Total Annual Fund Operating Expenses	0.89%

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 and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

      Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
INVESCO Technology Fund Class R5	91	284	493	1,096

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 most recent fiscal year, the Fund’s portfolio turnover rate was 48% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers engaged in technology-related industries. The Fund invests predominantly in equity securities. The principal type of equity securities purchased by the Fund is common stock.

      In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.

      The Fund may invest up to 50% of its total assets in foreign securities of issuers doing business in technology-related industries. The Fund will invest in American Depositary Receipts to gain exposure to foreign companies. American Depositary Receipts are receipts, issued by U.S. banks, for the shares of foreign corporations, held by the bank issuing the receipt. American Depositary Receipts are typically issued in registered form, denominated in U.S. dollars and designed for use in the U.S. securities markets. Purchasing American Depositary Receipts gives the Fund the ability to purchase the functional equivalent of foreign securities without going to the foreign securities markets to do so.

      The Fund can utilize derivative instruments, including call options and index futures. The Fund can utilize call options for hedging and investment purposes. A call option is an option contract in which the buyer has the right, but not the obligation, to buy a specified quantity of a security at a specified price within a fixed period of time. For the seller of a call option, an option contract represents an obligation to sell the underlying security at the specified price if the option is exercised by the buyer. The seller is paid a premium for taking on the risk associated with the obligation.

      Index futures can be used to gain exposure to the broad market by equitizing cash and as a hedge against downside risk. A stock index futures contract is an exchange-traded contract that provides for the delivery, at a designated date, time and place, of an amount of cash equal to a specified dollar amount times the difference between the stock index value at the close of trading on the date specified in the contract and the price agreed upon in the futures contract; no physical delivery of stocks comprising the index is made.

      In selecting securities for the Fund, the portfolio managers use a research-oriented bottom-up investment approach, focusing on issuer fundamentals and growth prospects. Security selection is then further refined by valuation and timeliness analysis. In general, the Fund invests in issuers that the portfolio managers believe currently exhibit or will develop a sustainable competitive advantage, a free cash flow generating business model and strong returns on invested capital. Technology issuers able to capitalize on the key secular themes identified by the portfolio managers are emphasized.

      Valuation plays a critical role in the security selection process. The primary metric used by the portfolio managers to determine a security’s target valuation is cash flow. In addition to valuation analysis, the portfolio managers analyze product cycle and seasonality-driven measures to help determine the best time to purchase or sell a security.

      While the portfolio managers may invest in securities of any market capitalization, they tend to favor mid- and large-cap securities to avoid liquidity problems that can be associated with some small-cap securities.

      The portfolio managers will consider selling the security of an issuer if, among other things, (1) a security’s price reaches its valuation target; (2) an issuer’s fundamentals deteriorate; (3) it no longer meets the investment criteria; or (4) a more attractive investment opportunity is identified.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

      Depositary Receipts Risk. Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts or to pass through to them any voting rights with respect to the deposited securities.

      Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

      Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

      Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

      Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

      Mid-Capitalization Risk. Stocks of mid-sized companies tend to be more vulnerable to adverse developments in the above factors and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

      Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

      Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

      Technology Sector Risk. Many products and services offered in technology-related industries are subject to rapid obsolescence, which may lower the value of the issuers in this sector.

Performance Information

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing predominantly in a portfolio of equity securities of small- to medium-sized U.S. corporations. The Adviser seeks attractively valued companies experiencing a change that could have a positive impact on a company’s outlook. The Adviser emphasizes a value style of investing, seeking securities of companies that the Adviser believes are undervalued. The Adviser will consider selling a security if it reaches the Adviser’s estimate of fair value or if a more attractive investment opportunity is identified.       Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of U.S. issuers at the time of investment. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.       Under normal market conditions, the Fund invests at least 65% of its total assets in equity securities of small- to medium-sized companies. Under current market conditions, the Adviser defines small-and medium-sized corporations by reference to those with market capitalizations up to the largest companies represented in the Russell Midcap® Index, a medium-sized capitalization company index which consists of companies with capitalizations up to approximately $23 billion as of April 30, 2012. The Fund invests in equity securities, which are common stocks and preferred stocks, convertible securities, and equity-linked securities to purchase common stocks and other equity interests, such as partnership and trust interests.       The Fund may invest up to 20% of its total assets in securities of foreign issuers and may invest up to 20% of its total assets in real estate investment trusts (REITs).       The Fund can also utilize derivative instruments, including forward foreign currency contracts, futures contracts and options. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future foreign currency exchange rates. The Fund will use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.       The Fund can invest in futures contracts, including index futures, to seek exposure to certain asset classes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.       The Fund can also invest in options to mitigate risk. An option is a derivative financial instrument that specifies a contract between two parties for a future transaction on an asset at a reference price. The buyer of the option gains the right, but not the obligation, to engage in that transaction, while the seller incurs the corresponding obligation to fulfill the transaction. The price of an option derives from the difference between the reference price and the value of the underlying asset (commonly a stock, a bond, a currency or a futures contract) plus a premium based on the time remaining until the expiration of the option. Other types of options exist, and options can in principle be created for any type of valuable asset.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:       Risks of Investing in Value Stocks. Value stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Value stocks can continue to be undervalued for long periods of time and may not ever realize their full value.       Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues.       Risks of Investing in REITs. Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general and may involve duplication of management fees and other expenses. REITs may be less diversified than other pools of securities, may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets.       Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.       Convertible Securities Risk. The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.       Equity-Linked Securities Risk. Investments in equity-linked securities may subject the Fund to risks if the underlying equity security, reference rate or index underperforms or if the issuer defaults on the payment of the dividend or the common stock at maturity. Additionally, the trading market for particular equity-linked securities may be less liquid, making it difficult for the Fund to dispose of a particular security and to obtain market quotations for valuing the Fund’s portfolio.       Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.       Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.       Small- and Mid-Capitalization Risks. Stocks of small and mid-sized companies tend to be more vulnerable to adverse developments in the above factors and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.       Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.       Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.

The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.       The returns for Class R5 shown prior to June 1, 2010 are those of the Class A shares of the predecessor fund. Class R6 shares of the Fund have less than a calendar year of performance; therefore, the returns shown are those of the Fund’s (and the predecessor Fund’s) Class A shares, which are not offered in this prospectus. Class R5 and Class R6 shares would have different returns from the predecessor fund because, although the shares are invested in the same portfolio of securities, Class R5 and Class R6 shares have different expenses. The predecessor fund was advised by Van Kampen Asset Management.       Updated performance information is available on the Fund’s Web site at www.invesco.com/us.

INVESCO VAN KAMPEN COMSTOCK FUND

Fund Summary - INVESCO VAN KAMPEN COMSTOCK FUND

Investment Objective(s)

The Fund’s investment objective is to seek capital growth and income through investments in equity securities, including common stocks, preferred stocks and securities convertible into common and preferred stocks.

Fees and Expenses of the Fund

This 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 and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

            Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example INVESCO VAN KAMPEN COMSTOCK FUND (USD $)	1 Year	3 Years	5 Years	10 Years
Class R5	45	141	246	555
Class R6	42	132	230	518

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 most recent fiscal year, the Fund’s portfolio turnover rate was 17% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing in a portfolio of equity securities, consisting principally of common stocks, preferred stocks and securities convertible into common and preferred stocks. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks at the time of investment. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. The Fund emphasizes a value style of investing seeking well-established, undervalued companies believed by the Adviser to possess the potential for capital growth and income. The Adviser will consider selling a security if it meets one or more of the following criteria: (1) the target price of the investment has been realized and the Adviser no longer considers the company undervalued, (2) a better value opportunity is identified, or (3) research shows that the company is experiencing deteriorating fundamentals beyond the Adviser’s tolerable level and the trend is likely to be a long-term issue. The Fund may invest in issuers of small-, medium- or large-sized companies. The Fund may invest up to 25% of its total assets in securities of foreign issuers. The Fund may invest up to 10% of its total assets in real estate investment trusts (REITs).

           The Fund can utilize derivative instruments, including forward foreign currency contracts and futures contracts. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future foreign currency exchange rates. The Fund will use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

           The Fund can invest in futures contracts, including index futures, to seek exposure to certain asset classes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

           Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

           Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

           Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

           Small- and Medium-Sized Companies Risk. During an overall stock market decline, stock prices of small- or medium-sized companies often fluctuate more than stock prices of larger companies or the market averages in general. In addition, such companies typically are subject to a greater degree of change in earnings and business prospects than are larger companies and may be less liquid than larger-sized companies. In addition, small- and medium-sized companies may have more limited markets, financial resources and product lines, and may lack the depth of management of larger companies.

           Value Investing Risk. A value style of investing emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than the returns on other styles of investing or the overall stock markets.

           Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues.

           Risks of Investing in Real Estate Investment Trusts (reits). Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general. In addition, REITs depend upon specialized management skills, may not be diversified, may have less trading volume, and may be subject to more abrupt or erratic price movements than the overall securities markets. REITs must comply with certain requirements of the federal income tax law to maintain their federal income tax status. Investments in REITs may involve duplication of management fees and certain other expenses.

           Convertible Securities Risk. The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

           Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.

           Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and Van Kampen Comstock Fund’s (the predecessor fund) performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to those of the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

           The returns for Class R5 shown prior to June 1, 2010 are those of the Class A shares of the predecessor fund. Class R6 shares of the Fund have less than a calendar year of performance; therefore, the returns shown are those of the Fund’s (and the predecessor Fund’s) Class A shares, which are not offered in this prospectus. Class R5 and Class R6 shares would have different returns from the predecessor fund because, although the shares are invested in the same portfolio of securities, Class R5 and Class R6 shares have different expenses. The predecessor fund was advised by Van Kampen Asset Management.

           Updated performance information is available on the Fund’s Web site at www.invesco.com/us.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers engaged in energy-related industries. The Fund invests predominantly in equity securities. The principal type of equity securities purchased by the Fund is common stock.       In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.       The Fund may invest up to 100% of its net assets in foreign securities of issuers doing business in energy-related industries. The Fund invests in issuers of all market capitalizations.       Generally, the Fund’s investments are divided among the four main energy subsectors: (1) major oil issuers; (2) energy services issuers; (3) oil and gas exploration/production issuers; and (4) natural gas and logistic pipeline issuers. Portfolio weightings among these and other subsectors will be adjusted according to current economic conditions. In selecting securities for the Fund, the portfolio managers use a research-oriented, bottom-up investment approach, focusing on reasonably priced energy issuers with above average production volume growth, as well as earnings, cash flow and asset value growth potential independent of commodity pricing. The investment strategy focuses on identifying issuers with the ability to increase production while controlling costs by implementing new technologies, locating new discoveries (such as oil, natural gas, and/or coal) or boosting production volumes. In general, the Fund emphasizes issuers that the portfolio managers believe are strongly managed and will generate above average long-term capital appreciation.       The Fund can utilize derivative instruments, including call options. The Fund can utilize call options for hedging and investment purposes. A call option is an option contract in which the buyer has the right, but not the obligation, to buy a specified quantity of a security at a specified price within a fixed period of time. For the seller of a call option, an option contract represents an obligation to sell the underlying security at the specified price if the option is exercised by the buyer. The seller is paid a premium for taking on the risk associated with the obligation.       The portfolio managers will consider selling a security of an issuer if, among other things, (1) a security reaches its price target; (2) a change in fundamentals occur—either issuer specific or industry wide; (3) a change in management occurs; or (4) a more attractive investment opportunity is identified.

An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:       Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.       Energy Industry Sector Risk. The businesses in which the Fund invests may be adversely affected by foreign, federal or state regulations governing energy production, distribution and sale as well as supply-and-demand for energy resources. Although individual security selection drives the performance of the Fund, short-term fluctuations in energy prices may cause price fluctuations in its shares.       Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.       Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.       Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.       Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.       Small- and Mid-Capitalization Risks. Stocks of small and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.       Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

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 and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

      Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
INVESCO Energy Fund Class R5	79	246	428	954

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 most recent fiscal year, the Fund’s portfolio turnover rate was 61% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers engaged in energy-related industries. The Fund invests predominantly in equity securities. The principal type of equity securities purchased by the Fund is common stock.

      In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.

      The Fund may invest up to 100% of its net assets in foreign securities of issuers doing business in energy-related industries. The Fund invests in issuers of all market capitalizations.

      Generally, the Fund’s investments are divided among the four main energy subsectors: (1) major oil issuers; (2) energy services issuers; (3) oil and gas exploration/production issuers; and (4) natural gas and logistic pipeline issuers. Portfolio weightings among these and other subsectors will be adjusted according to current economic conditions. In selecting securities for the Fund, the portfolio managers use a research-oriented, bottom-up investment approach, focusing on reasonably priced energy issuers with above average production volume growth, as well as earnings, cash flow and asset value growth potential independent of commodity pricing. The investment strategy focuses on identifying issuers with the ability to increase production while controlling costs by implementing new technologies, locating new discoveries (such as oil, natural gas, and/or coal) or boosting production volumes. In general, the Fund emphasizes issuers that the portfolio managers believe are strongly managed and will generate above average long-term capital appreciation.

      The Fund can utilize derivative instruments, including call options. The Fund can utilize call options for hedging and investment purposes. A call option is an option contract in which the buyer has the right, but not the obligation, to buy a specified quantity of a security at a specified price within a fixed period of time. For the seller of a call option, an option contract represents an obligation to sell the underlying security at the specified price if the option is exercised by the buyer. The seller is paid a premium for taking on the risk associated with the obligation.

      The portfolio managers will consider selling a security of an issuer if, among other things, (1) a security reaches its price target; (2) a change in fundamentals occur—either issuer specific or industry wide; (3) a change in management occurs; or (4) a more attractive investment opportunity is identified.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

      Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

      Energy Industry Sector Risk. The businesses in which the Fund invests may be adversely affected by foreign, federal or state regulations governing energy production, distribution and sale as well as supply-and-demand for energy resources. Although individual security selection drives the performance of the Fund, short-term fluctuations in energy prices may cause price fluctuations in its shares.

      Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility.

Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

      Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

      Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

      Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

      Small- and Mid-Capitalization Risks. Stocks of small and mid-sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

      Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

Performance Information

The investment team generally emphasizes issuers with solid balance sheets and operational cash flow that supports sustained or increasing dividends. Through fundamental research, financial statement analysis and multiple valuation metrics, the management team estimates a target price for each security over a two- to three-year investment horizon. The portfolio managers then construct a portfolio which they believe provides the best total return potential based on a combination of price appreciation, dividend income and a favorable risk profile.       The portfolio managers consider whether to sell a particular security when any of these factors materially change.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing in a portfolio of equity securities, consisting principally of common stocks, preferred stocks and securities convertible into common and preferred stocks. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks at the time of investment. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. The Fund emphasizes a value style of investing seeking well-established, undervalued companies believed by the Adviser to possess the potential for capital growth and income. The Adviser will consider selling a security if it meets one or more of the following criteria: (1) the target price of the investment has been realized and the Adviser no longer considers the company undervalued, (2) a better value opportunity is identified, or (3) research shows that the company is experiencing deteriorating fundamentals beyond the Adviser’s tolerable level and the trend is likely to be a long-term issue. The Fund may invest in issuers of small-, medium- or large-sized companies. The Fund may invest up to 25% of its total assets in securities of foreign issuers. The Fund may invest up to 10% of its total assets in real estate investment trusts (REITs).            The Fund can utilize derivative instruments, including forward foreign currency contracts and futures contracts. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future foreign currency exchange rates. The Fund will use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.            The Fund can invest in futures contracts, including index futures, to seek exposure to certain asset classes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:            Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.            Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.            Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.            Small- and Medium-Sized Companies Risk. During an overall stock market decline, stock prices of small- or medium-sized companies often fluctuate more than stock prices of larger companies or the market averages in general. In addition, such companies typically are subject to a greater degree of change in earnings and business prospects than are larger companies and may be less liquid than larger-sized companies. In addition, small- and medium-sized companies may have more limited markets, financial resources and product lines, and may lack the depth of management of larger companies.            Value Investing Risk. A value style of investing emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than the returns on other styles of investing or the overall stock markets.            Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues.            Risks of Investing in Real Estate Investment Trusts (reits). Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general. In addition, REITs depend upon specialized management skills, may not be diversified, may have less trading volume, and may be subject to more abrupt or erratic price movements than the overall securities markets. REITs must comply with certain requirements of the federal income tax law to maintain their federal income tax status. Investments in REITs may involve duplication of management fees and certain other expenses.            Convertible Securities Risk. The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.            Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.            Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

INVESCO VAN KAMPEN AMERICAN VALUE FUND

Fund Summary - INVESCO VAN KAMPEN AMERICAN VALUE FUND

Investment Objective(s)

The Fund's investment objective is to seek to provide a high total return by investing in equity securities of small- to medium-sized corporations.

Fees and Expenses of the Fund

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees INVESCO VAN KAMPEN AMERICAN VALUE FUND	Class R5	Class R6
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none	none
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, whichever is less)	none	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses INVESCO VAN KAMPEN AMERICAN VALUE FUND		Class R5	Class R6
Management Fees		0.72%	0.72%
Distribution and/or Service (12b-1) Fees		none	none
Other Expenses	[1]	0.16%	0.10%
Total Annual Fund Operating Expenses	[1]	0.88%	0.82%

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 and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example INVESCO VAN KAMPEN AMERICAN VALUE FUND (USD $)	1 Year	3 Years	5 Years	10 Years
Class R5	90	281	488	1,084
Class R6	84	262	455	1,014

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 most recent fiscal year, the Fund's portfolio turnover rate was 30% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing predominantly in a portfolio of equity securities of small- to medium-sized U.S. corporations. The Adviser seeks attractively valued companies experiencing a change that could have a positive impact on a company’s outlook. The Adviser emphasizes a value style of investing, seeking securities of companies that the Adviser believes are undervalued. The Adviser will consider selling a security if it reaches the Adviser’s estimate of fair value or if a more attractive investment opportunity is identified.

      Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of U.S. issuers at the time of investment. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.

      Under normal market conditions, the Fund invests at least 65% of its total assets in equity securities of small- to medium-sized companies. Under current market conditions, the Adviser defines small-and medium-sized corporations by reference to those with market capitalizations up to the largest companies represented in the Russell Midcap^® Index, a medium-sized capitalization company index which consists of companies with capitalizations up to approximately $23 billion as of April 30, 2012. The Fund invests in equity securities, which are common stocks and preferred stocks, convertible securities, and equity-linked securities to purchase common stocks and other equity interests, such as partnership and trust interests.

      The Fund may invest up to 20% of its total assets in securities of foreign issuers and may invest up to 20% of its total assets in real estate investment trusts (REITs).

      The Fund can also utilize derivative instruments, including forward foreign currency contracts, futures contracts and options. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future foreign currency exchange rates. The Fund will use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

      The Fund can invest in futures contracts, including index futures, to seek exposure to certain asset classes. A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled through either physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.

      The Fund can also invest in options to mitigate risk. An option is a derivative financial instrument that specifies a contract between two parties for a future transaction on an asset at a reference price. The buyer of the option gains the right, but not the obligation, to engage in that transaction, while the seller incurs the corresponding obligation to fulfill the transaction. The price of an option derives from the difference between the reference price and the value of the underlying asset (commonly a stock, a bond, a currency or a futures contract) plus a premium based on the time remaining until the expiration of the option. Other types of options exist, and options can in principle be created for any type of valuable asset.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

      Risks of Investing in Value Stocks. Value stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. Value stocks can continue to be undervalued for long periods of time and may not ever realize their full value.

      Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues.

      Risks of Investing in REITs. Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general and may involve duplication of management fees and other expenses. REITs may be less diversified than other pools of securities, may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets.

      Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

      Convertible Securities Risk. The Fund may own convertible securities, the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

      Equity-Linked Securities Risk. Investments in equity-linked securities may subject the Fund to risks if the underlying equity security, reference rate or index underperforms or if the issuer defaults on the payment of the dividend or the common stock at maturity. Additionally, the trading market for particular equity-linked securities may be less liquid, making it difficult for the Fund to dispose of a particular security and to obtain market quotations for valuing the Fund’s portfolio.

      Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

      Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

      Small- and Mid-Capitalization Risks. Stocks of small and mid-sized companies tend to be more vulnerable to adverse developments in the above factors and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

      Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

      Preferred Securities Risk. There are special risks associated with investing in preferred securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and Van Kampen American Value Fund’s (the predecessor fund) performance to that of a broad-based securities market benchmark, style-specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to those of the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

      The returns for Class R5 shown prior to June 1, 2010 are those of the Class A shares of the predecessor fund. Class R6 shares of the Fund have less than a calendar year of performance; therefore, the returns shown are those of the Fund’s (and the predecessor Fund’s) Class A shares, which are not offered in this prospectus. Class R5 and Class R6 shares would have different returns from the predecessor fund because, although the shares are invested in the same portfolio of securities, Class R5 and Class R6 shares have different expenses. The predecessor fund was advised by Van Kampen Asset Management.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers engaged in technology-related industries. The Fund invests predominantly in equity securities. The principal type of equity securities purchased by the Fund is common stock.       In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.       The Fund may invest up to 50% of its total assets in foreign securities of issuers doing business in technology-related industries. The Fund will invest in American Depositary Receipts to gain exposure to foreign companies. American Depositary Receipts are receipts, issued by U.S. banks, for the shares of foreign corporations, held by the bank issuing the receipt. American Depositary Receipts are typically issued in registered form, denominated in U.S. dollars and designed for use in the U.S. securities markets. Purchasing American Depositary Receipts gives the Fund the ability to purchase the functional equivalent of foreign securities without going to the foreign securities markets to do so.       The Fund can utilize derivative instruments, including call options and index futures. The Fund can utilize call options for hedging and investment purposes. A call option is an option contract in which the buyer has the right, but not the obligation, to buy a specified quantity of a security at a specified price within a fixed period of time. For the seller of a call option, an option contract represents an obligation to sell the underlying security at the specified price if the option is exercised by the buyer. The seller is paid a premium for taking on the risk associated with the obligation.       Index futures can be used to gain exposure to the broad market by equitizing cash and as a hedge against downside risk. A stock index futures contract is an exchange-traded contract that provides for the delivery, at a designated date, time and place, of an amount of cash equal to a specified dollar amount times the difference between the stock index value at the close of trading on the date specified in the contract and the price agreed upon in the futures contract; no physical delivery of stocks comprising the index is made.       In selecting securities for the Fund, the portfolio managers use a research-oriented bottom-up investment approach, focusing on issuer fundamentals and growth prospects. Security selection is then further refined by valuation and timeliness analysis. In general, the Fund invests in issuers that the portfolio managers believe currently exhibit or will develop a sustainable competitive advantage, a free cash flow generating business model and strong returns on invested capital. Technology issuers able to capitalize on the key secular themes identified by the portfolio managers are emphasized.       Valuation plays a critical role in the security selection process. The primary metric used by the portfolio managers to determine a security’s target valuation is cash flow. In addition to valuation analysis, the portfolio managers analyze product cycle and seasonality-driven measures to help determine the best time to purchase or sell a security.       While the portfolio managers may invest in securities of any market capitalization, they tend to favor mid- and large-cap securities to avoid liquidity problems that can be associated with some small-cap securities.       The portfolio managers will consider selling the security of an issuer if, among other things, (1) a security’s price reaches its valuation target; (2) an issuer’s fundamentals deteriorate; (3) it no longer meets the investment criteria; or (4) a more attractive investment opportunity is identified.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers engaged in technology-related industries.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:       Depositary Receipts Risk. Depositary receipts involve many of the same risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts or to pass through to them any voting rights with respect to the deposited securities.       Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.       Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.       Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.       Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.       Mid-Capitalization Risk. Stocks of mid-sized companies tend to be more vulnerable to adverse developments in the above factors and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.       Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.       Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.       Technology Sector Risk. Many products and services offered in technology-related industries are subject to rapid obsolescence, which may lower the value of the issuers in this sector.

INVESCO Utilities Fund

Fund Summaries - INVESCO UTILITIES FUND

Investment Objective(s)

The Fund’s investment objective is long-term growth of capital and,

secondarily, current income.

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees INVESCO Utilities Fund	Class R5	Class R6
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none	none
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, whichever is less)	none	none

Annual Fund Operating Expenses INVESCO Utilities Fund		Class R5	Class R6
Management Fees		0.75%	0.75%
Distribution and/or Service (12b-1) Fees		none	none
Other Expenses	[1]	0.11%	0.10%

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 and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

      Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example INVESCO Utilities Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class R5	88	274	477	1,061
Class R6	87	271	471	1,049

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 most recent fiscal year, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of issuers engaged in utilities-related industries. The Fund invests predominantly in equity securities.

       In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement.

      The Fund may invest up to 25% of its net assets in foreign securities, including non-U.S. dollar denominated securities, of issuers doing business in utilities-related industries.

      In selecting investments, the portfolio managers seek to identify issuers predominantly within the electric utility, natural gas, water and telecommunications industries. The investment team generally emphasizes issuers with solid balance sheets and operational cash flow that supports sustained or increasing dividends. Through fundamental research, financial statement analysis and multiple valuation metrics, the management team estimates a target price for each security over a two- to three-year investment horizon. The portfolio managers then construct a portfolio which they believe provides the best total return potential based on a combination of price appreciation, dividend income and a favorable risk profile.

      The portfolio managers consider whether to sell a particular security when any of these factors materially change.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

      Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

      Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

      Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

      Sector Fund Risk. The Fund’s investments are concentrated in a comparatively narrow segment of the economy, which may make the Fund more volatile than non-concentrated funds.

      Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

      Utilities Sector Risk. The following factors may affect the Fund’s investments in the utilities sector: governmental regulation, economic factors, ability of the issuer to obtain financing, prices of natural resources and risks associated with nuclear power.
