Risk reward is decent, assuming the price will move slightly above prior high for the target. Can also use the ATR Stops as a trailing stop loss (wait for daily close below line, then stop loss goes slightly below the low of that day).
Do not like really the high P/E on this stock. Stock is priced very high assuming everything is going to go right and this company can generate big profits going forward. That said, the high P/E hasn't been a concern on the ride up, so it may still be good for more technical upside.
