Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 38% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in convertible 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. A convertible security is a bond, preferred stock or other security that may be converted into a prescribed amount of common stock at a prestated price. Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, may retain that common stock to permit its orderly sale or to establish long-term holding periods for tax purposes. The Fund is not required to sell the common stock to assure that the required percentage of its assets is invested in convertible securities. The Fund’s convertible securities may include lower rated fixed-income securities commonly known as junk bonds. The convertible securities also may include exchangeable and synthetic convertible securities. Unlike traditional convertible securities whose conversion values are based on the common stock of the issuer of the convertible security, synthetic and exchangeable convertible securities are preferred stocks or debt obligations of an issuer which are combined with an equity component whose conversion value is based on the value of the common stock of a different issuer or a particular benchmark (which may include a foreign issuer or basket of foreign stocks, or a company whose stock is not yet publicly traded). In deciding which securities to buy, hold or sell, the Adviser considers market, economic and political conditions. The Adviser sells a security when it believes that it no longer fits the Fund’s investment criteria. The Fund can also utilize derivative instruments, including forward foreign currency 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 may also invest in real estate investment trusts (REITs). The remaining 20% of the Fund’s assets may be invested in common stocks directly, non-convertible preferred stock, non-convertible fixed-income securities, and/or foreign securities. The foreign securities may include non-US dollar denominated securities and depositary receipts. The Fund’s fixed-income investments may include zero coupon securities, which are purchased at a discount and generally accrue interest, but make no payment until maturity.
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: Convertible Securities. The values of convertible securities in which the Fund may invest may be affected by market interest rates. The values of convertible securities also may be affected by the risk of actual issuer default on interest or principal payments and the value of the underlying stock. Additionally, an issuer may retain the right to buy back its convertible securities at a time and price unfavorable to the Fund. The value of a synthetic convertible security will respond differently to market fluctuations than a convertible security because a synthetic convertible security is composed of two or more separate securities, each with its own market value. 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. Fixed-Income Securities. All fixed-income securities are subject to two types of risk: credit risk and interest rate risk. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Lower rated fixed-income securities (commonly known as junk bonds) are subject to greater risk of loss of income and principal than higher-rated securities. The prices of junk bonds are likely to be more sensitive to adverse economic changes or individual corporate developments and may be subject to a greater risk of default than higher-rated securities. During an economic downturn or substantial period of rising interest rates, junk bond issuers and, in particular, highly leveraged issuers may experience financial stress. Common Stocks and Other Equity Securities. In general, stock and other equity securities values fluctuate in response to activities specific to the company as well as general market, economic and political conditions. 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. 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.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	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 performance to that of a broad-based securities market/style specific benchmark and a peer group benchmark with investment objectives and strategies similar to those of the Fund. The Fund’s and Morgan Stanley Convertible Securities Fund’s (the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class A, Class B, Class C and Class I Shares of the predecessor fund. The predecessor fund was advised by Morgan Stanley Investment Advisors Inc. Class A, Class B, Class C and Class I shares of the predecessor fund were reorganized into Class A, Class B, Class C and Class Y shares, respectively, of the Fund on June 1, 2010. Class A, Class B, Class C and Class Y shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Predecessor fund performance for Class A and Class B shares has been restated to reflect the Fund’s applicable sales charge. Performance for Class B shares assumes conversion to Class A shares eight years after the start of the performance period. Updated performance information is available on the Fund’s Web site at www.invesco.com/us.
