You could potentially explain the normal trading hours bump because of that, but the after hours is definitely on the earnings news.

Look at the after hours volume and price movement. It's definitely an earnings related move.

I'm not sure why this is modded down. There is a general trend up in the market over the past few days, and given that the FB price has recently been displaying a higher volatility than its peers, you would expect the kind of movement you are seeing with respect to the rest of its peers.

.. Are you serious?
