Stocks tank when they miss expectations.
Ken, you should really read up on stock market history. Just because it's in the past, doesn't mean it can't teach you something useful. You should focus, in particular, on periods of market mania and their aftermath.
BTW, sometimes stocks go up or down for apparently no reason at all or react to news in exactly the opposite way from what a reasonably rational person might expect. Market psychology has a way, over history, of pushing investors beyond the bounds of rational behavior. And when it corrects from an extreme it tends to overcorrect.
We are at such an extreme now and I would submit the bulls' arguments for stocks like AMZN and YHOO, particularly that traditional measures of value do not apply, as evidence of the mania (there is much more evidence, BTW). Granted, timing the extreme top or bottom is nearly impossible, but that does not mean that one should just do nothing. Learn from the past and protect your assets.
