Friday's candle is very bullish and with decent volume retesting the 50 day sma. 158 should be solid support and that's the retest I plan on entering with $170 March calls for $6.50 to give it time. Will give it a $4.25 stop, which should align with below that wick of Friday's bullish candle.
My target on NVDA is $170, or extreme $176 to close out the swing.
Let's see what she does next week :).
Cheers.
