Why?

P.I.E. is one of the manufacturer which produce and provide technical chips in the market, included iphone chips as well

but Apple already announced, for the new coming of iphone5, the attorneyship has no longer to P.I.E. anymore.

they will pass the attorneyship to another manufacturer, instead of P.I.E.

so once the iphone5 release, the performance for P.I.E will be affected, and ofcoz the share as well.

for those who're still holding the P.I.E share, this is the time to sell it before the share drop. (personal opinion@@)
