No one knows for sure, least of all the so-called "experts." This is a fickle market. Market always go to an extreme, whether on the upside or as in this case the downside. This sellin is way overdone and it was not this bad, even after the 9/11 tragedy.
I hate like heck predicting anything, but based on the current mood on the Street, wouldn't be surprised to see AMAT down to $12 and many other stock getting hit a long with it. Hopefully this will not be the case.
