There are many people that recommend the straight forward full-index ETFs such as Vanguard's VOO for the S&P 500. I have also run across QQQ (Nasdaq / Tech heavy) and XLG (Curated set of S&P 500).
What index style ETFs have you uncovered in your research that you might recommend?
Has anyone had any success or warnings with some of the more exotic leveraged holding ETFs?
I'd be cautious with the more exotic leveraged ETF. Instead, for my non-investment accounts I've been mostly holding the Mag 7 since last year (after rotating out of pandemic stocks following the rebound). I shared my results over the last couple of years on by blog where I document my thinking for future reference/improvement (https://gmays.com/2-year-follow-up-on-buying-the-dip-on-pand...). My current IRR from that portfolio is 83.70% over the last couple years for context.
