FB call volume is very brisk from 79 to 83 strikes in the Jan30 weeklies. Put volume lags a good bit. Needless to say but the Feb 80 calls are very busy with over 10k contracts traded. Call volume looks to be topping put volume across all expirations. If FB does a YHOO then there are going to be a lot of unhappy call buyers after they get violated by IV bleed. I think that FB would need an AAPL like beat to get above 80 and hold. That seems like long odds to me.
