I think they BMSN should have come out with news sooner. When there is no news, people speculate with whats going on. Since most investors want to see a return on their investment, most outlooks are slanted in a positive direction. With no official word to combat the bias, it gives people a sense of hope thats out of reality. Then, when news finally drops, you get this effect - a bunch of people disappointed so they sell.
If there were more press releases just to give shareholders an update (maybe once per month), i think it would go a long way to ensure shareholder confidence.
