Wish I knew... I've seen it enough though including KERX... heck I bet SA has had 100 articles on KERX since 2009.
ALXA was one I caught on to early last year... SA did a little article so I picked up a 1,000 shares @ $0.41 as an experiment to see what would happen... then more articles came out and it rode up quickly... I got out at $.063 and then it crashed badly when ALXA had a CRL issue. Got in again after the R/S and before the FDA ruling with another 100 shares in the $4 area, rode it up to $5.80 again and got out. It got shorted to death post FDA approval. It was an interesting test... I won twice but bet a lot of people got fleeced... heck... I could've gotten fleeced as well.
I guess it's just a matter of knowing what they are going to pump next and getting in before or as the articles come out... and then getting the hell out fast enough. Don't trust ANYTHING you read on SA... that's one thing I know for sure. Remember that Jeremy Richards stuff in March of last year? KERX took a beating thanks to SA and Adam F.
I've held KERX for quite a while... for some dumb reason I actually believe in this Bio. I might get burned again... or I might not. I averaged down quite a bit last year and will ride the Zerenex storm out til the end win or lose.
