Nasdaq 100 Growth Leaders Portfolio 20263 [Member]  
Entity Information [Line Items]  
Definition of Rule 35d-1 Term in Fund Name [Text Block] Principal Investment Strategy. The Portfolio seeks to achieve its objective by principally investing in a portfolio of common stocks of companies derived from the NASDAQ-100 Index. The NASDAQ-100 Index includes securities of 100 of the largest domestic and international non-financial companies listed on The NASDAQ Stock Market based on market capitalization. The NASDAQ-100 Index reflects companies from all major industries, except for companies that are classified as “financials” according to the Industry Classification Benchmark (“ICB”) (i.e., it excludes companies under ICB Industry Code 8000). Security types generally eligible for inclusion in the NASDAQ-100 Index are common stocks, ordinary shares, tracking stocks, shares of beneficial interest, limited partnership interests, as well as American Depositary Receipts (“ADRs”) that represent securities of non-U.S. issuers. As of the Initial Date of Deposit, all of the Portfolio’s investments are in securities of companies derived from the NASDAQ-100 Index that the Sponsor identifies as “growth leaders”.

Since its inception in 1985, the NASDAQ-100 Index has become the world’s preeminent large-cap growth index. Featuring some of the world’s most iconic companies, today the NASDAQ-100 Index defines modern day industrials. Invesco Capital Markets, Inc., the Sponsor, selects the securities for the Portfolio from among the NASDAQ-100 Index component list as most recently made available to the Sponsor prior to the Initial Date of Deposit. Although the NASDAQ-100 Index weights its component securities using a “modified market capitalization-weighted” methodology, which is a hybrid between equal weighting and conventional capitalization weighting, the Portfolio will be approximately equally weighted.

The Portfolio aims to invest in constituent securities of the NASDAQ-100 Index that are issued by companies that the Sponsor identifies as “growth leaders” using the following selection criteria. An initial universe of investable securities is created by quantitatively screening the NASDAQ-100 Index by: (1) eliminating companies with a share price below $5 at the time of selection; (2) eliminating companies whose three-year average revenue compound annual growth rate (“CAGR”) is less than 5%; and (3) eliminating companies whose three-year average earnings per share (“EPS”) CAGR is less than 10%. Our process utilizes both generally accepted accounting procedures (“GAAP”) and non-GAAP EPS figures. If the screens do not produce an adequate number of initial investable stocks, the Sponsor may either reduce or increase the percentage thresholds of screens 2 and 3 to adjust the initial universe size.
