95% of my current trades are day trades. I pulled in some nice gains in AAPL, GOOG, BIDU, MA, V over the past week. These high beta stocks keep ripping upwards. Which brings up the question: "When should I hold on to a stock and let my profits run?" For example: I had several Daytrade positions on AAPL which I sold for some nice profits. But today I wished that I would have held onto those positions for a hefty chunk of change.

Thanks in advance. - David
