what is the % change for each company since start of comp
Wish I could tell you, but I don't record the price movements, just the price at purchase (which could be different for every user) and the current price. I thought since there are so many websites with price history I could just get that data there.
For example, here's CML's history since the comp started testing last monday, if you want something else, just edit the share code:
