A good question, however, as a swing trader, I use a scan to find the best stocks given the market situation - then I just buy them. I currently have 5 stocks that I know very little about - which sounds risky, however.... I firmly believe in the power of mechanical trading systems. Based on a tested timer, buy the stocks that are generated from a screen, and hold them until the exit criteria is met.
I used to find when I did a lot of research on specific stocks, I would become attached to them. Tougher to sell a stock that you have invested so much time into.
So, while the markets have been bearish, thats usually the best time to see if you can find some stocks that have a high relative value, that have been beaten up. No question for example that AAPL falls under that category - a solid company that one could have picked up for $240 recently.
I picked up shares in COCO, TUES and MNI... although I really have no idea what Tuesday Morning actually does ;-)
