TEchnically FAcebook as been following this rising lower trendinline, but has failed ot make a new high. The ahs also been on a declining pattern with a sudden pop now that are out. FB also hasn't really had a good decline after popping and running for over 15 months in 2013 (15 months is usually where I see momentum names start to falter a bit.) .
Sooner or later facebook will need to get out of this base. But with decelerating and expenses expanding, combind with the apparent technicals, fb is in for one mean correction.
