Just what is your regimen for controlling the purchase of stock, including timing, for your portfolio?

When I am fully invested, I will look at each stock that looks attractive on the scan and make a short list. I then compare tem to the stocks in my portfolio. If a new stock is overwhelmingly better than something I hold, I may sell part or all of a holding and buy some of the new stock. However, the case to buy the new stock has to be very good. My extremely strong preference is to stick to what I have while they are still trending up. I maintain a very aggressive focus in my portfolio, which is minimally diversified. It would cut against this to buy too many small lots of stocks just because they are interesting.

Otherwise, I will only add a stock or stocks to my fully invested portfolio if a stock is sold, for whatever reason according to the trading plan.
