The wildest week in Wall Street's history is ending on an up note.

A rebound in retail sales in July helped the stock market push higher Friday. The week has been marked by seesaw trading. The Dow Jones industrial average rose or fell by more than 400 points each of the first four days of the week as investors reacted to concerns about the global economy and Europe's debt problems.

The Dow is finishing with a gain of 125 points, or 1.1 percent, to 11,269. The S&P 500 is up 6, or 0.5 percent, to 1,279. The Nasdaq is up 15, or 0.6 percent, to 2,508.

Two shares rose for every one that fell on the New York Stock Exchange. Volume was an above average 4.9 billion shares.

WASHINGTON (AP) — The mixed economic signals driving the stock market's record-setting swings this week keep coming. But on Friday, even a survey showing Americans are dismayed about the economy didn't stop the gains on Wall Street.

Conflicting reports on retail sales and consumer sentiment sent the Dow up, then down, then up again.By early afternoon, the Dow Jones industrial average was up 143 points. It rose more than 150 points early Friday after a government report consumers spent more on autos, furniture and gasoline in July, pushing up retail sales by the largest amount in four months. The Dow briefly turned negative after the release of a dismal survey on consumers' feelings about their personal finances and the economy.

The Reuters/University of Michgan survey of consumer sentiment fell to a 30-year low.

The retail sales data covered all of July, but financial markets didn't start their wild ride until July 22. The sentiment survey was taken over the past 10 days, as Americans watched the markets leap and dive on news about Europe's spreading financial crisis, the first-ever downgrade of the U.S.s long-term credit rating, signals that the job market improved slightly in July and strong earnings from a technology bellwether.

Normally, such a bad consumer survey would have pushed shares sharply lower for the day, said Quincy Krosby, an investment strategist with Prudential Financial.

"But these are not normal times," she said. Market volatility cuts both ways, sending shares way up or way down, Krosby noted. That can cause shares to defy economic data.

Markets worldwide gained on Friday despite a trade report Thursday that showed the economic slowdown might be a global phenomenon. France reported Friday that economic growth in the country slowed sharply in the second quarter. A ban on short-selling in several eurozone countries lifted bank shares across Europe and helped calm markets there.

In early-afternoon trading, the Dow gained 1.3 percent, to 11,286. The Standard & Poor's 500 index added 10 points, or 0.8 percent, to 1,182. The Nasdaq composite index gained 21 points, or .8 percent, to 2,513.

If shares close higher, it will be the first time in more than a month that the market has risen two days in a row. The Dow and the S&P last rose for two trading days on July 6 and 7.

At Thursday's close, the Dow had fallen more than 12 percent since July 21.

The strong retail sales added to other bits of more positive data about the economy. The government said last week that hiring picked up slightly in July after two dismal months, though employers still are adding jobs too slowly to significantly reduce unemployment. A Thursday report showed applications for unemployment benefits fell to a four-month low. Some analysts believe recently announced layoffs will cause that number to rise in the coming weeks.

A separate government report on Friday showed that businesses increased their stockpiles of everything from raw materials to retail products for the 18th month in a row.

Growing inventories are usually a sign of business confidence. But nervous consumers have held back recently; in June they cut their spending for the first time in nearly two years.If the market's gyrations spook consumers, people might spend even less just as retailers stock up for the crucial holiday season.

Investors are already dizzy from seesaw trading. Shares have swung by hundreds of points each day this week as traders react to news about the economy, Federal Reserve policy and the financial crisis in Europe.

The Dow Jones industrial average soared 423 points on Thursday. It had already fallen 634 points Monday, risen 429 Tuesday and fallen 519 Wednesday. Never before has the Dow had four 400-point swings in a row.

The Standard & Poor's 500 index has risen or fallen at least 4 percent each day. That has not happened on four consecutive days since November 2008, during the financial crisis.

High-speed trading by computers has contributed to the volatility, as shares hit high and low levels at which machines are programmed to buy or sell large numbers of shares.

But concerns over Europe's debt woes and a slowing global economy have also worried investors.

France's benchmark index, the CAC-40, rose 3.3 percent despite news that the nation's economy hit the brakes in the second quarter as exporters' wares piled up and consumers held onto their money. As France and Germany's heavily-indebted neighbors struggle financially, the two countries are shouldering most of the costs of rescuing Greece, Portugal and Ireland from defaulting on their debts.

Worries about debt issued by Italy and Spain, and the stability of banks there, have prompted the European Central Bank to buy their sovereign bonds, lowering their borrowing costs. Italy and Spain have Europe's third- and fourth-largest economies.

Most other major European markets rose by more than 3 percent, including Germany's DAX index, Italy's FTSE MIB and Spain's IBEX. London's FTSE index rose by more than 2 percent.

In the U.S., only two of the 10 industries in the S&P 500 were down by midafternoon on Friday. Telecommunications stocks were down 0.4 percent and financials were down less than 0.1 percent. Industrials led the index higher, gaining 2.2 percent.

Investment bank Morgan Stanely fell 5 percent amid concerns about U.S. banks' exposure to the financial crisis in Europe and lawsuits related to shoddy mortgages sold before the housing bubble burst. JPMorgan Chase & Co. and Goldman Sachs Group Inc. also slid.

Goodyear Tire & Rubber Co. surged 10 percent after the company told investors that it expects revenue this quarter to offset its higher raw material costs. The company had said last month that raw material costs might hurt its profits in the second half of the year.

DeVry Inc. plunged more than 18 percent, the most in the S&P 500, after the company said that new student enrollment tumbled this summer. For-profit education companies are under pressure to raise their admissions standards so that students will be more likely to find jobs and pay off their government-backed loans. That has caused their share prices to fall sharply this year.
