Some investing advice for pessimists

Being pessimistic about investing has a lot going for it, especially these days. A lot of mental tricks can kick in when we're in the market, and they often come from too much optimism.

However, pessimists can hurt themselves, Colorado Springs, Colorado financial planner and CBS MoneyWatch blogger Allan Roth says. Here are two ways.

1. There’s a basic principle called loss aversion that influences our financial decisions: the high you get from winning isn’t as powerful as the low you feel from losing. This phenomenon is exacerbated for pessimists. “When losses happen, pessimists are miserable, and when gains happen, they’re not as happy as they think they will be,” says Dan Ariely, a professor of psychology and behavioral economics at Duke University and author of The Upside of Irrationality. Pessimists should try to view risk as the cost of doing business, and remind themselves that it makes sense to take some risk. For example, consider all the probabilities when investing for retirement: The odds of the stock market going nowhere for 30 years are fairly low, while the odds of money markets lagging inflation over the next 30 years are fairly high.

2. “If you tend to only see the negative, don’t look too frequently at your investments because you will only be miserable,” Ariely says. Even more important, don’t be reactive. It goes back to loss aversion: Be careful of doing something spur of the moment (like pulling all of your money out of the stock market) because you want to avoid the misery you fear is coming. “It’s good to evaluate, but don’t evaluate based on emotion,” he says, especially if you’re in a doom and gloom mood. Instead, take the long view. If the market has just crashed, for example, ask yourself: a year or two after a market crash, is it usually higher or lower?

Understanding investing isn't hard; it's understanding your own mind that's tough.
