Agreed...never trust Sierra..they just pump and dump...BEWARE
I 100% agree with you dwm. Stock market is totally rigged.
Sentiment: Strong Buy
I have burnt my fingers on other bio stocks, that play the same trick of reverse split, and secondary offering.
Sentiment: Strong Sell
My advice would be not to invest too much in one stock. If you are smart, diversify..Do your DD on other stocks such as CTSO, ADXS, ALXA, CTIC.
