Serious question-no hurry... Steve mentioned how AAPL,AMZN,GOOGL,FB & MSFT are 21% of SPX/40% of QQQ and are pretty much responsible for this last move up to new highs. My question is: When money flows into the ETFs does that make the ETFs have to go and buy the components in the percentages in respective index? Example: $1 buys QQQ so AAPL gets 10 cents/MSFT gets 10 cents etc My point is when $$$$ flows into QQQ and SPX, is it a self-fulfilling proposition that the FAANGs are going to go up? Thanks!
