Both. I put in limit orders where I think it will go - generally around the 50% - 65% retracement level of the recent move up. If it doesn't get hit, I look for a break of the 2-3 day downtrend line using my broker's real time charts.

So for NVAX, I'm targeting about 1.60 - we're getting close now. I'm looking to buy late today or early tomorrow.

There's no guarantee these stocks will have another run, but I think the odds do favor it - there's usually another shoe out there waiting to drop.
