for us "investors" who think the stock price should be rational, welcome to china crap stocks. As an example, CHFR shot up to .59 a couple days ago, after tanking to less than half a penny. I'd bought at an average of about ten cents for a small stake. I couldn't get a trade thru near the high, so I took .23 for about 2/3's of my shares and may or may not buy back for more if it goes to sub .10 again.
This is just one example of how these thrown out babes can go up by many 1000's% for little reason.
