It appears that POWI continues to perform even when the market appears to be turning into a downtrend. I would be careful here and take some of the profits if they are there for you. Look to buy on a break of the upper line.

Bought POWI today.

I also forgot to mention here that I picked up CPST as well @ 2.01 a few days ago. CPST closed up to a new minor 52 week high.
