Long-term investor for most of my stocks. Generally just looking for sound companies that can generate dividends that beat inflation by at least 1.5 - 2.0 points. Reinvest those dividends until retirement, and enjoy! I do occasionally buy stocks that have suffered hugely in the PR department but still have sound fundamentals (LULU when the shear pants issue came up, AAPL when it was generally agreed upon that they haven't invented anything revolutionary in a while). Assuming there has been appreciable gain, these types of issues can be sold when one of my long-term dividend stocks suffers catastrophic PR events but remains sound fundamentally.
I follow a (hopefully) disciplined value investing philosophy in my investments. I am always looking out for good businesses trading at a discount to fair value due to temporary market stress or investor panic.
