The infamous saying is a 50% drop requires a 100% gain, which not arguing, but it got me thinking, what if a 50% drop, read as a 50% increase as equal. The way to do this is to latch onto the purchase price, then compare that to the increase or decreases. I know this isn't normal, but does anyone know of a website or something that could do this? If I put in that I bought a share at 10/share, it is now 200/share and goes up 10%, ie 220, it would actually read a 200% increase as 20 dollars up compared to my 10/share would be a 200% increase.
This is mainly just a thought experiment
