Some people might think that dropping 10% and then gaining 10% returns a stock to the same price. No, that is completely wrong.
Index : $100 + 10% = $110 - 10% = $99 + 10%
= $108.90 - 10% = $98.01 + 10% = $107.811
Soxl 3x : $100 + 30% = $130 - 30% = $91 + 30%
= $118.3 - 30% = $82.81 + 30% = $107.653
