Shares of Roku (NASDAQ:ROKU) likely put in a major pivot top on Tuesday. After a three-bar surge on the daily chart, the stock humped again but is now putting in a possible topping tail. Topping tails are epic reversal signals, especially on charts in extreme overbought territory like ROKU. In addition, upside moves usually end on three-bar surges. A pull back is likely in store to a target price of $115. This trade setup is pure technical analysis. This means there is finally a reason to short ROKU that has teeth.
