I feel poor
With the large swings in the DOW lately, I am inclined to believe there is more than market psychology in play. Like when it moves 100+ points either direction in one afternoon. The financial news isn't changing that fast. And with the possible exception of the Euro debt daily developments, not that many real surprises either, that haven't already been factored in already.
You are right, the market does have an effect on people's inclination to spend money. The volatility is almost as bad as a steady decline. I have read some articles saying high-speed automated trading is partly to blame.
