Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
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. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. 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:
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] oef_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 most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] oef_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, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund invests primarily in equity securities. The principal type of equity security in which the Fund invests is common stock.
For purposes of the Fund's 80% investment policy, the Fund considers an issuer to be doing business in energy-related industries if it meets at least one of the following tests: (1) at least 50% of its gross income or its net sales come from activities in energy-related industries; (2) at least 50% of its total assets are devoted to producing revenues in energy-related industries; or (3) based on other available information, the Fund’s portfolio managers determine that its primary business is within energy-related industries. Such other available information may include industry or sub-industry classifications from any one or more third-party providers, such as those using the Global Industry Classification Standard (GICS®), the North American Industry Classification System (NAICS), or the Bloomberg Industry Classification System (BICS).
The Fund will concentrate its investments in the securities of issuers engaged primarily in energy-related industries. Issuers engaged in energy-related industries include, but are not limited to, oil companies, oil and gas exploration companies, natural gas pipeline companies, refinery companies, energy conservation companies, coal companies, alternative energy companies, innovative energy technology companies, water companies and electric companies. Generally, the companies in which the Fund invests fall within the three main energy sub-industries: (1) integrated oil and gas issuers; (2) oil and gas equipment and services issuers; and (3)
oil and gas exploration/production issuers. Portfolio weightings among these and other sub-industries will be adjusted according to current economic conditions.
The Fund may invest up to 100% of its net assets in securities of foreign issuers doing business in energy-related industries, which may include securities of issuers located in emerging market countries, i.e., those that are generally in the early stages of their industrial cycles. The Fund may invest in securities of issuers of all capitalization sizes.
The Fund can invest in derivative instruments, including forward foreign currency contracts.
The Fund can use forward foreign currency contracts to seek to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated; though the Fund has not historically used these instruments.
Derivatives and other instruments that provide investment exposure to the investments that are the subject of the 80% investment policy stated above and derivatives that provide investment exposure to one or more market risk factors associated with such investments may be included in the Fund’s 80% investment policy.
The Fund is non-diversified, which means it can invest a greater percentage of its assets in a small group of issuers or any one issuer than a diversified fund can.
The investment team primarily uses a fundamental bottom-up analysis to seek to identify investments with quality management teams and quality assets trading at attractive valuations. The investment strategy places emphasis on valuation and risk/reward profiles of potential investments. In valuing companies, the investment team takes a long-term view on commodity prices and uses a constant marginal cost of production commodity price. The commodity price does not change unless a persistent structural change in the commodity occurs. Price-to-cash flow (P/CF), price-to-net asset value (P/NAV) and price-to-earnings (P/E) are the valuation metrics the investment team uses to assess the attractiveness of a security. Top-down macroeconomic research, including an assessment of factors such as worldwide economic activity, government policy, employment, inflation, supply/demand dynamics, currency market dynamics, international trade, technological advances, as well as business, equity and credit market cycle analysis, is also considered as a check and balance to sub-industry allocation that results from bottom-up analysis.
The portfolio managers will consider selling a security if, among other things, (1) a security reaches its target price; (2) a change in fundamentals occurs-either company specific or industry wide; (3) a change in corporate focus and/or management occurs; or (4) a more attractive investment opportunity is identified.

Risk [Text Block] oef_RiskTextBlock
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in
particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
INVESCO Energy Fund | INVESCO Energy Fund | Energy Sector Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Energy Sector Risk. Changes in worldwide energy prices, exploration and production spending, government regulation, armed conflict, world events, local and international politics, economic conditions, exchange rates, transportation and storage costs and labor relations can affect companies in the energy sector. These companies are also at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism, armed conflict and natural disasters. Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments, geopolitical conflict and related economic sanctions also could affect companies in this sector. Investments in the energy sector may be cyclical and/or highly volatile and subject to swift price fluctuations. Energy markets are subject to both short- and long-term trends that impact demand for and supply of energy commodities. A decrease in the production of energy commodities or a decrease in the volume of such commodities available may adversely impact the financial performance of companies operating in the energy sector. In addition, significant declines in the price of oil may contribute to significant market volatility, which may adversely affect the Fund’s performance.
INVESCO Energy Fund | INVESCO Energy Fund | Investing in Stocks Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Investing in Stocks Risk. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall or rise sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.
The prices of individual stocks generally do not all move in the same direction at the same time. However, individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), Fund share values may fluctuate more in response to events affecting the market for those types of securities.
INVESCO Energy Fund | INVESCO Energy Fund | Foreign Investment Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of possible seizure, expropriation, nationalization, political or social instability, changes in economic or taxation policies or other adverse political or economic developments (in which the Fund could lose its entire investments in a certain market) and the difficulty of enforcing obligations in other countries, including the possible adoption of foreign governmental restrictions such as exchange controls. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency
blockage and/or transfer restrictions and higher transactional costs. To the extent the Fund invests in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns, unless the Fund has hedged its foreign currency exposure. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, may not always be successful. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. From time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company’s performance. Additionally, one or more of these companies could suffer damage to its reputation if the market identifies it as a company that invests or deals with countries that the U.S. government identifies as state sponsors of terrorism or is subject to sanctions.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Emerging markets usually are subject to greater market volatility, political, social and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.
INVESCO Energy Fund | INVESCO Energy Fund | Small- and Mid-Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Small- and Mid-Capitalization Companies Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies. They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings
in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all.
INVESCO Energy Fund | INVESCO Energy Fund | Derivatives Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. Derivatives strategies may not always be successful. For example, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions. 
INVESCO Energy Fund | INVESCO Energy Fund | Non-Diversification Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Non-Diversification Risk. The Fund is non-diversified and can invest a greater portion of its assets in the obligations or securities of a small number of issuers or any single issuer than a diversified fund can. A change in the value of one or a few issuers’ securities will therefore affect the value of the Fund more than if it was a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
INVESCO Energy Fund | INVESCO Energy Fund | Valuation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund’s valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Fixed income securities are often valued assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available or deemed non-representative of fair value for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund’s net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.
INVESCO Energy Fund | INVESCO Energy Fund | Management Risk [Member]

Risk [Text Block] oef_RiskTextBlock
Management Risk. The Fund is actively managed and depends heavily on the Adviser's judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience
losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser's investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.
