NEW YORK (AP) -- It's a quiet start to May in the stock market. Major averages are beginning the day just about flat.

Wall Street is watching monthly auto sales. Industry watchers expect overall sales to rise 2 percent for April compared with a year earlier. The market will also get economic reports Tuesday on the health of manufacturing and construction.

Just after the opening bell, the Dow Jones industrial average is off two points at 13,212. The Standard & Poor's 500 index is up a fraction of a point at 1,399. And the Nasdaq composite is up three at 3,049.

The S&P finished April in the red, its first losing month since November. The Dow managed a small gain.
