ETF Leverage Reversal
The big drop in March 2020 was completely avoidable. When the short ETF pair started to go out of sync due to increased volatility, the system leader apparently fell asleep at the wheel and never corrected the ratios. In addition, large positions in individual stocks were taken at a time of spiking volatility, betting on sharp recoveries that did not materialize. I would avoid this strategy like the plague.
