Facebook has had a couple of bad days since the data scandal, but I think that is a good opportunity to take a position around $155 with a stop loss just below $148 where it found support, the bounce could take us to the .786 $177.90 fib level of the last impulse and maybe star a new Elliot wave count since it has finished an ABC correction pattern.

Happy trading ;)
