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.
Interested in market breadth. But market cap is my favorite metric. I have been trading $JNS all year on the Bill Gross hire. Won a few big ones, got drilled during the correction. Previously all $FSLR. Bay Area, Cambridge, now DC.
