It is not a coincidence that this dropped sharply in conjunction with the divdend ex date event. Despite being in a better technical position than past dividend events(managed to exceed the 50m/a this time), it still repeated the pattern than has played out regularly in the past. The price action in this stock has become very predictable, which plays into the short sellers hands. The 3 day RSI is 1.29 basis the close, you don't get that very often. This is inicative of momentum short selling by large funds, probably those that have played this time and time again, with success. Algo traders are blowing away investors and destroying any confidence they may have. You can find some Canadian Energy stocks where this isn't happening but they are very few because Canadian oils are the meal of choice for short sellers.
