There might be a second shoe coming (it was downgraded by one house to day, probably a major reason for the drop). SNDK.
Actually, this was the third or fourth shoe over the past three weeks or so. Several downgrades in addition to the one today (though the one today was one of the odder ones--they based it partially on the belief that inventories will be liquidated at the end Dec, making ASPs fall--but most buyers are having a hard time finding product now; who is holding inventory? And why?). The INTC/MU venture (still vaporware, but nevermind). The initial rejection of the ITC for a fasttrack finding against STM for patent finding (another ruling is rumored to be imminent). The various STM countersuits (most if not all of which are amazing nonsense, IMHO). Must be a spider for all these shoes to be dropping.
But you're right. Absent a positive ruling on their STM suit, probably SNDK won't do much anytime soon. On the other hand, if there is a positive ruling, the stock will likely jump nicely, IMO. And if negative, the converse.
