Although GWPH seems to be in a bullish pennant since September of 2016, it is currently retesting the support around $110 (for the third time). This may be a great setup to short if GWPH breaks below $110. There is a gap to around $39 that may be filled.
GWPH has already filled the 9/23/2016 gap to 109.xx. We shall see if GWPH continues this pattern in the coming months. If GWPH has heavy volume coming into the $110 range, it will most likely break through and continue it's bearish descent. Historically it seems that GWPH has always filled its past gaps.
