Hello, I've read in several sources that the value of the stocks in an ETF can drift away from the price. So an ETF trading at $190 could have only $180 of stocks pegged to the $190 price. I even read somewhere (the internet... who knows how reliable), that one ETF was trading at a price 2x the value of its underlying assets (maybe a fast-moving tech sector ETF). I think with mutual funds you get a settlement at the end of the day that makes the values proper. Has anybody had experience with NAV drift? I've read about it, but I'd like to hear from people who actually have invested in ETFs. I think it would be nice to sprinkle some ETF stuff into a portfolio, but the drift between the price of the ETF and the value of the underlying shares has me concerned. I'm new at this, especially ETFs.
