Shares of FireEye Inc (NASDAQ:FEYE) continue their collapse after the neck-line of a head and shoulder pattern was violated. The break of a neck-line triggers a head and shoulder pattern, ultimately taking it to its final resting target. In the case of FireEye Inc, the final resting target is calculated out to be $13.50. The stock currently trades at $15.60, so there is still significant downside to go. I will be an interested buyer at $13.50, when the head and shoulder pattern has completed.
