Conversely, you could say it's a self-fulfilling prophesy. If every technical trader knows that every other tech trader will sell if it drops below a certain support level, then it certainly will take a tumble if it drops below that price. Traders cause increased volatility. But, that's all it is; short term noise. In the longer term the stock will go to it's true value.
Nobody is panicking. Long term investors will do quite well with AVAV. HYSR, well...not so much. BTW, my change in sentiment didn't have anything to do with the fools article, which was basically positive.
