Mostly, it is pointless. Outlandish predictions not based on any fact or evidence isn't very helpful. When people say AMBS will trade over .15 cents by such and such a day...and then it doesn't, it actually has the opposite effect on longs. It gets hopes up...then lets them down. Shorts sometimes disguise themselves as longs and also engage in this kind of outlandish pumping. When the predictions don't come true, the let down often leads to discouragement and premature selling. As a long, I prefer we stay somewhat within reason on our predictions. If we have an outlandish prediction, we should at least give a reason why. If we don't do this...we'll have a useless message board.
As a human with a conscience, I don't like people getting screwed on short term trades someone took them in on, but they can always average down on dips. If this did plummet I would buy way more which would help me as a long.
scappy: I was in Insys Therapeutics (INSY) when it had it's IPO in May of this year. It has gone from $8 to over $34 in just 4 months!! Check it out. How did they do it? They have a good cancer pain product that is selling real well: Subsys. But another reason in my opinion is that management went into a dark mode for a few years (not communicating with shareholders very much) and chased away all the small retail investors and small day traders. (I was one of the few small guys that stayed) It also did away with it's message board so shorts couldn't bash the stock. Trust me, it was a nice ride up from $8 to $34 in four months. All the #$%$ manipulators on the message board are not doing the stock any favors, they are hindering it.
