BLK looks really good. Prob short it under the 50 day MA.
Crox I would prob wait for the bounce up after yesterdays bad news to add a short position
NFLX I wouldnt short it yet. Its in an uptrend and even though its been slowing its been channeling sideways but still making higher lows. It definitely has potential but I wouldnt feel comfortable until I had a definite trend reversal sign. Also Id wait for the ema(6) to cross over the ema(13)its almost there but this could bounce up higher.
