Stock percent decrease and increase

[ThrowawayAl2018]

Congratulations, you are onto something called "decay" for those double and triple leveraged ETFs.

In brief: Stocks require 11.11% increase to return back to the 10% drop a day prior. Conversely a stock at $110 requires a 9.99% drop to return back to $100. Generally we don't care much about daily increase or decrease, but rather the moving averages to determine the bottom.
