I feel like I just went through this in the LED industry...a "takedown" so that the big boys can get in cheap. Here's how it goes...a group of MM and hedge funds realize that this is a real growth story but they missed it. So, they short it, downgrade it and sell any shares they have. When there are no more sellers they buy back in. This just happened with CREE, VECO,RBCN, etc. I think that is what is going in here. They keep beating on earnings and getting new contracts, but the thought is that austerity and other competition will drive the stock down...I don't believe it.
We're just hanging on for the ride, bud. Maybe like a lamprey eel and it's host.
Learn to watch the particular analyst and figure out if you can use him as a trend or counter trend indicator.
For example, could we have used a very recent call as a reversal indicator if we looked back, say 4 months from now? We'll know in about that time. We know that GS will sell the investor anything that makes GS money. Do a sanity check against other sources.
