Your calculation is specifically "misleading" (as I indicated in my previous post).
At .08 MONA is 20% below EFGO at pre split trading (@ .0001) or 60% below EFGO at pre split trading (@ .0002).
In general, that is how someone describes their losses. As in "I'm 20% down on my investment" or "I've lost 60% since the stock traded at its high". You described the stock as trading at 250% below pre split levels. Which is actually incorrect. The stock at .08 would have to *GAIN* 250% to be at pre split levels, but we are not as you put trading 250% "below" pre split levels.
