Who decides how much of the QQQQ weighting that each stock is weigh in the QQQQ. you have 5 stocks making almost 30% of the market. no single stock should have more than 3% of QQQQ. basically trading the QQQQ is same as trading apple or google.
it should be weighted by revenue not market cap. the market capitalization is not real and is b.s. only thing real is sustainable long term future cash revenue and net cash profit and number of employees and customers and value of assets or book value of assets of the company.
