another article (which I also cannot find again) that claimed to show that the 2x the daily performance of S&P500 (SSO etf) was not grossly dangerous to hold long term, despite the warnings.

So I just had a brainstorm and did a backtest. Can't use portfoliovisualizer since they kneecapped it.

But: https://testfol.io/?d=eJytT7FOAzEM%2FRfPQUo7dMiMmF...

Since SSO inception (6/21/2006):
SPY CAGR: 10.43% MaxDD: -55.19%
SSO CAGR: 13.99% MaxDD: -84.67% (!!!!)

Huge drawdown in 2008/2009. Didn't recover until May 2014. Might have been okay with half-decent timing.
