Should I sell when my stocks are growing?
There is an approach which suggests that each weekend you should review your positions as if they were stocks to be considered for purchase on Monday. I can't offer advice on picking stocks, but it's fair to say that you need to determine if the criteria you used to buy it the first time is still valid. I own a stock trading at over $300, purchased for $5. Its P/E is still reasonable as the darn E just keeps rising.  Unless your criteria is to simply grab small gains, which in my opinion is a losing strategy, an 8% move up would never be a reason to sell, in and of itself. Doing so strikes me as day trading, which I advise againgst.
