Stocks closed higher Wednesday as positive results from Amazon.com ( AMZN - Get Report) and other bellwether companies jump-started blue chips and produced smaller gains in the recently moribund technology sector.

The Dow Jones Industrial Average rose 71.24 points, or 0.63%, to 11,354.49, and the S&P 500 was up 3.67 points, or 0.28%, to 1305.41. The Nasdaq Composite gained 3.33 points, or 0.14%, to 2333.63.

"The Nasdaq treaded water all day and it hasn't been doing well all week," said Paul Nolte, director of investments with Hinsdale Associates. "It's been the weakest for a while now. The industrial complex has been doing better as a whole. I was surprised by the market's general strength today because the numbers put the Federal Reserve back into the mix."

Semiconductors again pressured the Nasdaq, as the Philadelphia Semiconductor Sector index fell 0.5%. Elsewhere, the Amex Oil index was off 2.3%. Gainers included the Amex Gold Bugs index, up 1.5%, and the S&P Retail index, which finished up 0.9%.

The Dow's best performer was General Motors ( GM), ending the session up 8.1%. Merrill Lynch upgraded the shares to neutral from sell, saying it believes the automaker will successfully execute its restructuring plan using its overfunded U.S. pension. GM added $1.74 to $23.15.

The 10-year Treasury bond was down 7/32 in price to yield 5.10%, while the dollar was weaker against the yen and euro.

About 1.77 billion shares traded on the New York Stock Exchange, with advancers narrowly beating decliners by a 6-to-5 margin. Trading volume on the Nasdaq was 2.11 billion shares, with decliners matching advancers.

The market didn't have much of a reaction to the Federal Reserve's beige book, which showed that the economy continued to expand in March and the first half of April. Most of the Fed's 12 districts reported that high energy prices were leading to increased cost pressures, while some mentioned the rising costs of metal.

In addition, most districts noticed a cooling of residential real estate activity. Reports on manufacturing activity in most districts remained positive. Some districts reported that labor markets are tightening, especially for skilled workers.

Before the opening bell, the Commerce Department said durable-goods orders rose 6.1% in March, more than triple the expected gain. Excluding aircraft, which increased 71% for the month, new orders were up 2.8%, the largest rise since August.

The same agency also said new homes jumped 13.8% in March to an annual rate of 1.21 million units. Economists had anticipated new-home sales would rise to an annual rate of 1.1 million. The data helped the Philadelphia Housing Sector index, which was up 1.2% after the report.

On Tuesday, a buoyant reading on existing-home sales raised concerns about the future of Fed interest rate policy and sent major stock indices lower, with the Nasdaq falling for the fourth straight session.

Analysts said Wednesday's reports raised the likelihood of two more official rate hikes -- a quarter-point tightening next month and an identical increase when the Fed meets in June.

"We have good earnings today, but there's just too much good economic news," said Larry Wachtel, senior market analyst with Wachovia Securities. "We're increasing the likelihood of a rate hike in June. The data are coming in stronger than expected, so the Street is expecting another hike. The better the news, the more likely the Fed will tighten. It's a strange phenomenon that good news can be bad news."

Marc Pado, a market strategist with Cantor Fitzgerald, agrees that "too much economic strength is perceived to be a negative for the markets, because it will force the Fed to anticipate the inflationary pressures, even if it means dragging down economic growth. Despite what the Fed says, its No. 1 objective is price stability, not economic growth."

June crude, which has lost 3% since topping out above $75 a barrel Friday, slipped by 95 cents to close at $71.93 a barrel. The Energy Department said in its weekly inventory data that crude stocks were down 200,000 barrels last week, while gasoline stocks dropped 1.9 million barrels and distillates fell by 1 million barrels.

Precious metals finished higher again Wednesday. Gold rose, adding $7.80 to $642, and silver was up 25 cents to $12.81 an ounce.

Another big story early Wednesday involves chemical company Engelhard ( EC - Get Report), which detailed a plan to repurchase about 20% of its stock at a 17% premium to the market price. The buyback will be financed with debt and is intended to counter a hostile takeover offer made three months ago by Germany's BASF. Englehard rose 20 cents, or 0.5%, to $38.50.

WellPoint ( WLP) kicked off the earnings cascade, saying its first-quarter profit rose 20% to $731.8 million, or $1.09 a share. The health insurer beat on the bottom line, although sales of $13.61 billion were slightly light. WellPoint was lower by 30 cents, or 0.4%, to close at $70.44.
