Look for Valid Support and Resistance Levels Looking to Bloomberg's Monthly Publication for Opportunities

Look, Don't Touch

There is nothing like a market correction or a general upswing to change perfectly normal investors into fanatics who have market updates text messaged to their cell phones every five minutes. As with fidelity, the axiom, "look, don't touch" is insufficient because the more you look, the more you want to mess around with your investments. It is not clear if it is a symptom or a cause, but this rabid over-monitoring almost always leads to unnecessary churning in sufferers' portfolios.
