The share has moved as expected, and looking at the chart, we should reach around $ 170-180. the pattern is "M-top" and neck line somewhere @ $ 240 area.
For now we are slightly oversold, and we could pullback to $ 250-250 before the decline will set in to 170.
Strategy SELL @ $ 245-250 and take profit @ $ 175. SL above $ 280.
