Stocks ended moderately higher Tuesday amid reports that Saddam Hussein was losing control of Iraq's second-largest city. But a vote in the Senate to slash President Bush's stimulus plan took some wind out of an afternoon rally.

The

Dow Jones Industrial Average

ended up 65 points, or 0.8%, at 8280, while the

Nasdaq

gained 21 points, or 1.6%, to end at 1391. The

S&P 500

climbed 10 points, or 1.2%, to 875.

The Dow was up as much as 100 points following unconfirmed reports that a popular uprising against Hussein was under way in Basra, heightening hopes that the ruler could be toppled soon. British troops were said to be surrounding the city. Meanwhile, Secretary of Defense Donald Rumsfeld said war "is much closer to the beginning than to the end," although he reiterated that victory isn't in doubt. U.S. troops continued their march toward Baghdad, piling up arms and ammunition in preparation for an assult on the Iraqi capital.

Bush said that the U.S.-led coalition will prevail over Iraq and that the "regime will be disarmed, creating a safer world." He also unveiled his supplemental budget request for $75 billion to be used for military action and the reconstruction of Iraq.

The Basra-related gains were reduced in the session's final hour after the Senate voted 51 to 49 to cut Bush's proposed $728 million tax reduction in half. The surprise reversal occurred after Republican Lincoln Chafee and Democrat Ernest Hollings changed their votes.

"The tax proposal, which would eliminate taxes on corporate dividends, was construed as big positive for stocks since it made them more attractive. So even though this will mean a smaller budget deficit, the fact that the proposal was not fully approved was seen as a negative sign by the market," said Daniel Morgan, fund manager and market analyst at Noble Financial Group.

Michael Mach, vice president and portfolio manager at Eaton Vance, money-management firm, noted, "Trading is focused on what will happen in the next few hours. It's mainly speculative, based on options programs and daytrading. Right now, all this uncertainty has created some select opportunities in the stock market and we're trying to ferret out and capture these opportunities."

Stocks were coming off a brutal session in which the Dow tumbled 307 points to 8214. The plunge erased Friday's rally and left the average holding roughly 850 points of gains since hitting lows two weeks ago.

Among other assets, crude oil for May delivery fell 69 cents to $27.97 a barrel in New York, reversing earlier gains. The 10-year Treasury note gained 3/32 to yield 3.95%. The dollar remained weaker against the euro and yen.

Energy shares gained during the session, with

moving up 1.5% to $35.83 and

( RD) gaining 3% to $41.12.

"Everyone is so focused on the war effort and not enough on market data that it just creates more opportunity to buy," said Martin McKeever at Merrill Lynch's Equity Trading Retirement Group. McKeever believes once war cools down, consumer confidence could get a boost.

James Melcher, president of money-management firm Balestra Capital, was more skeptical. "Investors were overreacting in the past few sessions. There's nothing you can trade or pin your hopes on. Any mild advance or setback sends markets every which way."

Trading volume was light, with 1.3 billion shares changing hands on the New York Stock Exchange and advancers ahead of decliners by almost three-to-one. On the Nasdaq, about 1.4 billion shares were traded, with gainers outpacing losers by two to one.

Two economic reports released Tuesday had little effect on market activity. The Conference Board's consumer confidence index fell to 62.5, the lowest in almost a decade amid a soft job market and higher gasoline prices. Economists had expected the reading decline to 62, from 64 the previous month.

The government said February existing home sales dropped to an annualized rate of 5.84 million, from 6.09 million a month earlier. The figure was slightly above the 5.80 million expected by economists.
