The share price of Plug Power Inc (PLUG) rose after the bell yesterday as the company announced that it has bought fuel cell-stack maker, ReliOn Inc., for about $4 million in an all-stock deal. Currently, Plug Power stock is up 5.48%, or $0.41, in pre-market trading on the Nasdaq.
I put a few hundred into PLUG a few months back, and I've made thousands. It's very volatile though, which is why I took such a small position. I have more $ in BLDP.
