NEW YORK (MarketWatch) -- U.S. stocks turned lower Tuesday -- bringing a two-day rally to a halt -- as energy and technology shares dragged down the overall market, offsetting cheer over the government's plan to help revive the economy.

"If the Fed and the Treasury are backing the U.S. financial system, who is backing the U.S.?" asked Tony Crescenzi, bond strategist at Miller Tabak. "For now, investors are putting this question aside and believing that such doomsday scenarios are a low probability."

Among the limited blue-chip advancers, shares of J.P. Morgan Chase & Co. , rose 6.8%.

Pay it back

Before the opening bell, the Federal Reserve unveiled a plan to lend up to $200 billion to back the issuance of debt, including student, auto and credit-card loans as well as those backed by the Small Business Administration. .

That announcement overshadowed data that showed the U.S. economy contracting at a 0.5% annual rate in the third quarter, slightly faster than initially estimated.

A separate report showed home prices in 20 major cities falling by 1.8% in September from the month before, and by a record 17.4% from the prior year. .

Falling gas prices bolstered consumer sentiment in November, according to the Conference Board's latest monthly survey, which showed confidence climbed from a record low in October.

In another illustration of the banking sector's troubles, the Federal Deposit Insurance Corp. reported bank loan losses climbed during the third quarter, but the reserves set aside for future problems didn't keep pace. .

Meat-packer Hormel Foods Corp. reported solid fourth-quarter sales growth, but it also said losses on an investment trust dragged profits down.
