The Commerce Department reported that sales of new single-family homes fell by 3.9 percent last month to a seasonally adjusted annual rate of 848,000. It was the slowest sales pace in nearly seven years and dimmed hopes for a rebound in the troubled housing market.

Economists have been watching the housing industry for a hint about where the economy is heading. The disappointing data came amid continued concern about the subprime mortgage market, which has been slammed by an increase in delinquencies in recent months.

This sent major indexes down throughout most of the session, with the Dow Jones industrials racking up triple-digit losses. Investors used the decline to buy some shares before the second quarter ends on Friday, analysts said.

"The market is already worried more about economic growth than inflation, so I think you're going to see reactions like this," said Todd Salamone, director of trading at Schaeffer's Investment Research in Cincinnati. "Overall, its impressive from the comeback we've had. There's been a whirlwind of attention about housing's effects on the economy, it isn't anything new and these pullbacks are buying opportunities."

Bonds rose, with the yield on the benchmark 10-year Treasury note falling to 4.60 percent from 4.61 percent late Friday. Bond investors have been hoping that a slowing economy will cause the Federal Reserve to lower interest rates.

Overseas, Japan's Nikkei stock average closed up 0.24 percent. Britain's FTSE 100 down 0.75 percent, Germany's DAX index was down 1.02 percent, and France's CAC-40 was fell 1.04 percent.

FOCUS REMAINS ON ECONOMIC DATA

Investors also are focused on a spate of economic data due this week, including the gross domestic product report due on Wednesday.
