Those are amazing numbers, but 2011 - 2023 was a strong market. How would this strategy have done from 2000 - 2009?

Good question. I guess you could perhaps model it by downloading the daily historical prices for QQQ or SPY and calculating the daily results like the 2X or 3X ETF does. Remembering to include the Expense Ratio. Verify by checking agaist the actual results when the ETF was available.

And here I had no plans for the next couple of days. ;-)
