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. 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 41% of the average value of its portfolio.

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:
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 primarily in technology-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 50% of its total assets in foreign securities of issuers doing business in technology-related industries. 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 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. The Fund can utilize derivative instruments, specifically 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 buyer 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.

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: 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. 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. 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.
Risk Lose Money [Text]	rr_RiskLoseMoney	As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	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.

[1] The Adviser has contractually agreed, through at least April 30, 2013, to waive advisory fees and/or reimburse expenses of Series I shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Series I shares to 1.30% of average daily net assets. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the number reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board of Trustees and Invesco Advisers, Inc. mutually agree to amend or continue the fee waiver agreement, it will terminate on April 30, 2013.
