Dow hits a 4-year high

An interesting juncture in the recent market run-up: Economic indicators continue to improve, more or less, and quarterly earnings continue to look good, more or less. But there's concern that the employment picture is getting choppy and that the housing market is going nowhere fast. So what's an investor to do? Today, most bets were on growth; analysts cited better-than-expected manufacturing news and a decent April for auto sales. The Dow was up more than 100 points for most of the day, but a bunch of last-hour selling pared the gain to 65 points, to 13,279.
