"Sabby reports 5.1% passive stake in Anthera Pharmaceuticals" Sounds like a positive. I am expecting a jump. Of course the cynic in me asks if they were responsible for driving the price down? Makes a 5% stake a lot cheaper to buy.
Sabby has a 50/50 track record IMO. Some stocks they buy because they know it's good and they will make a ton. Others they know will fail and they take those over for there own purposes. Just My Opinion from other stocks I have seen them on. With that said $4-5 million is a lot. I think they have high hopes for this stock.
