NEW YORK, Feb 26 (Reuters) - U.S. stocks jumped on Tuesday after IBM <IBM.N> said it will buy back $15 billion of its shares, boosting the computer hardware sector, while energy companies' shares climbed as oil rose past $101 a barrel.
On Tuesday, Moody's comfirmed bond insurer MBIA Inc's <MBI.N> "AAA" rating. MBIA shares shot up 4.3 percent to $15.20 on the New York Stock Exchange. That news followed a rally triggered late on Monday by signs that the the two largest bond insurers could stabilize.
The Dow and Nasdaq each rose more than 1 percent.
Computer services company IBM said the buyback program could boost its 2008 earnings, and lifted the broader market as it showed it can still earn robust profits even as economic data indicates the U.S. economy is on the brink of a recession.For details, see [
]Energy shares were the top driver of the S&P's advance, with a weak dollar and geopolitical tensions driving the price of oil higher. Shares of Chevron Corp <CVX.N> rose 1.1 percent to $88.11.
"The market is looking for positives. IBM's a big component of the market, it's a large weighting. That, combined with Ambac and the move late yesterday, is giving short-term direction in the market," said Mark Schlarbaum, a trader at Global Capital Management, in Conshohocken, Pennsylvania.

The Nasdaq Composite Index < > was up 30.32 points, or 1.30 percent, at 2,357.80.Stocks added to gains after Federal Reserve Vice Chairman Donald Kohn said risks to economic growth were more of a threat than inflation and that the Fed was ready to do what it needs to respond to "difficult times." Since last August, the Fed has taken an aggressive approach to cutting interest rates to stimulate the economy.
IBM shares rose 4.4 percent to $114.87 and contributed the most to the Dow's gains.
Hewlett-Packard Co <HPQ.N> told a technology investment conference that the computer and printer maker remains confident about its previous earnings forecast, which was ahead of Wall Street's estimates.
HP's shares added 2.6 percent to $49.36.
The tech and energy sector news overshadowed a report earlier in the day showing inflation making an unwanted comeback and another report that consumer confidence hit a 5-year low.
U.S. producer prices last month had their biggest 12-month gain in more than 26 years, the government said, dealing a blow to investors' hopes for more Fed rate cuts to avert a recession.
The Conference Board, a private research group, said its index of consumer confidence for February fell to a 5-year low, hurt by a much tougher job market. (Additional reporting by Jennifer Coogan; Editing by Jan Paschal)
