a lot of the price moment up on OPK seems to have been driven by insider buying. looks like CEO (Dr. Frost) is buying up shares rather frequently. I got in with OPK at $6.08 and just sold them today at $7.08. It's nice to see that Dr. Frost is buying into his company....I would entered into another position if it entertains $6 again.
Personally, would like to see some more news in addition to insider buying moving this stock.
