U.S. stocks were little changed on Monday as a sharp drop in oil futures weighed on the energy sector but helped the broader market.

Investors awaited the release of housing data that is expected show a decline in home resales last month.

Existing home sales for May are due at 10 a.m. (1400 GMT). Economists forecast a dip to 5.98 million annualized units from 5.99 million in April.

Lead-month crude oil futures were down $1.22 to $67.92 a barrel.

Oil is definitely helping. It had looked like it was going to break through $70, said Angel Mata, managing director of listed equity trading for Stifel Nicolaus Capital Markets in Baltimore. But (the indexes) are probably not going to stay up for much of the morning. There's a lot of bearish talk out there.

The Dow Jones industrial average was up 3.49 points, or 0.03 percent, at 13,363.75. The Standard & Poor's 500 Index was down 2.62 points, or 0.17 percent, at 1,499.94. The Nasdaq Composite Index was down 6.67 points, or 0.26 percent, at 2,582.29.
