I was hearing that before too. Its been a while since I looked into it but I remember reading how a huge chunk of that cash was mainly from the biggest companies like Google, Apple, Microsoft and more I can't remember right now. Some of the money was cash borrowed due to low interest rates. A lot of it was deposited in banks which meant it was being loaned out and invested somewhere else.
Either way, I wouldn't pretend to know how QE factors into any specific stock.
Just more generally QE tends to bid up stocks for a variety of reasons.
