Bernanke has mentioned the "wealth effect" of rising stock prices many times since rates went to zero so yes! It was all part of the big plan. Just because it wasn't mentioned at the time rates were doesn't mean it wasn't part of the plan.
Quote from MKTrader:
It wasn't stated at first, but Bernanke was bragging about how well small-caps were performing a year ago. It's certainly in their interest to keep stocks propped up as much as possible.
