When it comes to investing, Adam Davidson, cofounder and cohost of NPR's Planet Money, advises anyone who's feeling jumpy to relax. "Don't pay attention to the ups and downs," he says. "It costs money to make trades, and you're not going to be smarter than the market consistently. You're going to lose out eventually. You'll do much, much better if you follow a simple, conservative strategy."
