I think the thumping of the day award goes to STEC. Down 38% on around 6 times average volume.

Apparently, they turned in decent earnings, but one of their primary customers has announced an intent to carry inventory over into 2010.

Add to this a continuous selling by insiders, and the result is a good old fashioned butt whoopin'.

It's a real shame, too; I'm not wild about the stock, but I really do like their product.
