I like to find undervalued turnaround stories that are still in the 1st or 2nd inning. I listen to the conference calls, read the quarterly earnings, and sift through the numbers (I value both fundies and technicals, as well).
Buy and hold died. Follow the gurus cautiously. Some are blind. Buy dips. Buy momentum. Market is unknowable. Food always in demand. Energy too. Charts are like statistics: they can say whatever you want. Momentum + price action for swing trading.
