Stocks closed higher for a second straight session Tuesday, buoyed by another decline in oil prices, a rising dollar and a round of bargain-hunting.

The

Dow Jones Industrial Average

rose 37.32 points, or 0.36%, to 10,458.46; the

S&P 500

added 5.27 points, or 0.45%, to 1181.39; and the

Nasdaq

gained 8.25 points, or 0.41%, to 1999.32, having briefly regained the 2000 level earlier in the session. These are the first back-to-back up sessions for the major indices since March 3 and March 4.

"We had an unpleasant March, but yesterday we might have seen the possible reversal to the upside," said Al Goldman, chief market strategist with A.G. Edwards. "It meant that the market was oversold enough to attract buyers. We had enough of a correction, and sideline money did some bottom-fishing."

Trading volume on the

New York Stock Exchange

was 1.85 billion shares, with advancers beating decliners by a 9-to-7 margin. Volume on the Nasdaq was 1.65 billion shares, with advancers outpacing decliners by an 8-to-7 spread.

In other markets, the 10-year Treasury note fell 2/32 in price to yield 4.47%, while the dollar gained against the yen and euro for a second straight session. The dollar is now trading at a five-month high against the yen.

Oil fell, continuing the slide begun around midday Monday, as an International Monetary Fund laid the recent run-up in prices on perceptions of supply shortages rather than any underlying reality. The May crude contract finished down 97 cents to $56.04 a barrel.

Fed

Chairman Alan Greenspan took on the subject of high energy prices in a speech to an industry trade group Tuesday, reiterating his view that market dynamics eventually will cause demand for oil to moderate.

"Prices of spot crude oil and natural gas have risen sharply over the past year in the face of constrained supply and the firming of overall demand," Greenspan said. "But if history is any guide, should higher prices persist, energy use will over time continue to decline, relative to GDP. Long-term demand elasticities have proved noticeably higher than those that are evident short term. ... If sustained, these market technicals could encourage enough of an inventory buffer to damp the current price frenzy."

The speech comes ahead of closely watched weekly inventory data from the Energy Department on Wednesday morning.

"It's surprising to see oil dropping with the recent concern over gasoline supplies, but it's a catalyst for the market right now," said Robert Pavlik, portfolio manager with Oaktree Asset Management. "I think it takes a little concern away from the Fed increasing by 50 basis points at their next meeting, at least in the short term."

Stronger sectors Tuesday included biotech, drug, health care and financials. Weaker sectors were software and materials.
