Texas Instruments

(TXN) - Get Report

coaxed buyers back into semiconductor, retail and energy shares

The

Dow Jones Industrial Average

rose 82.63 points, or 0.78%, to 10,678.56, while the

S&P 500

added 9.81 points, or 0.8%, to 1241.48. The

Nasdaq Composite

gained 9.48 points, or 0.44%, to 2175.51. The 10-year Treasury was up 7/32 in price to yield 4.12%, while the dollar was lower against the yen and euro.

For the week, the Dow gained 2.2%, the S&P 500 rose 1.9% and the Nasdaq added 1.6%. All three indices notched their second-straight week of gains following Hurricane Katrina.

"I'm struck by the market's reaction today with everything surrounding the

Fed's

meeting in two weeks," said Paul Nolte, director of investments with Hinsdale Associates. "The initial reaction may be the wrong reaction. Today also showed that we've gotten much more positive on tech."

About 1.47 billion shares changed hands on the

New York Stock Exchange

, with advancers beating decliners by a 2-to-1 margin. Trading volume on the Nasdaq was 1.64 billion shares, with advancers outpacing decliners 3 to 2.

After rising modestly earlier, stocks got a second wind at midday when oil turned lower. October crude, which added 12 cents Thursday after bottoming out around $63, finished down 41 cents to $64.08 a barrel. Gasoline futures were down 7 cents at $1.96 a gallon.

"Investors seem to be focusing on three main items now," noted Michael Sheldon, chief market strategist with Spencer Clarke. "First, we have the upcoming earnings updates from companies. Second, the question of what will the

Fed

do at their next meeting. Third, how weak is the economy likely to be, and will inflation move higher after soaring energy prices."

The Philadelphia Semiconductor Index added 0.7% Friday, while the S&P Retail Index added 0.6%.

"Looking ahead, we have a lot of economic news next week," Sheldon said. "It's going to take a lot of time to get a clearer picture of how much the economy has weakened."

In the last economic report of the week, the Labor Department said that import prices for August rose 1.3% and export prices fell 0.1% in the same month.

Intel

(INTC) - Get Report

investors were upset a day after the company said third-quarter sales should be between $9.8 billion and $10 billion, in line with Wall Street estimates of $9.92 billion.

Thursday night's updates were some of the first company-specific events to capture Wall Street's attention since Katrina blew through the Gulf Coast nearly two weeks ago. Still, San Francisco

Federal Reserve

President Janet Yellen said the storm remains the economy's biggest threat.

"The size of these impacts depends in part on how quickly the vast energy infrastructure in the region can be brought back to operating condition," Yellen said, adding that the Fed is "still at an early stage in the process of assessing the effects of the hurricane."

Treasury Secretary John Snow, in a

CNBC

interview Friday morning, expressed more confidence in the economy's ability to recover.

"Clearly, it's devastating to the region and to the people that lost their jobs. It'll have a ripple effect on the economy as a whole," Snow said. "While the effects in the short term will be notable, they'll be temporary. We'll see the economy come back. GDP growth will continue to be positive."
