I appreciate this comment. It looks like if TQQQ perfectly tracked 3x the daily return of QQQ defined as the opening-price-to-opening-price or closing-price-to-closing-price return, then it would be up about 64% or 75% on the year (neglecting a dividend), and in real life it's up 74%. Wow! I don't think that people commonly buy TQQQ futures at annualized premiums of like 40% one day then sell them at annualized premiums of like 20% the next day, so it's harder for us to use TQQQ as the underlying.
