Again. The stock price doesn't know anything. It

It is a reaction to investor sentiment. As investors, we don't know anything either. I don't view this as a some sort of indicator of what is going to be on the call, but rather that the majority of investors (long and short) just deciding to wait and see.
Once the call occurs the share price will have something to digest, and will respond accordingly.
Some will say, that it should be creeping up in anticipation, and I would counter that it already has. A few times.
