Yahoo finance has it as a loser for the next 9 months out, then going up after that, based on current news. No idea what they used for this, the key point is if people buy or sell based on this information.

The fall this morning was probably a response to the Jack Project Veritas video and the rise back to the open was probably a result of buy orders kicking in, fairly standard movement.
