Trader Brian Jones on Twitter: "I tweeted $UMRX yesterday @ .80. Stock went up 300% by today afterwards. I didn't buy it because I missed that .80 trade and didn't want to chase because it was risky. Not that I didn't like it." / Twitter

I tweeted $UMRX yesterday @ .80. Stock went up 300% by today afterwards. I didn't buy it because I missed that .80 trade and didn't want to chase because it was risky. Not that I didn't like it.
