Dr. Frost was in China meetign with one of his other heavily owned companies, IDI.
Honestly I could care less about his insider buying, 137 million in OPK or 170 million in OPK, in both ways it shows faith.
Let alone his buying was non-stop at the start of november, nice if he buys, but if he doesn't for a day/week, who cares?
It's about the products and pipeline, and that will start to blossom from 1Q14 on.
Rayaldy is under SPA from the FDA, positive P3 results alone should nearly double the stock from this levels.
Gl with your position.
