U.S. stocks rose strongly Thursday, reversing a four-session losing run, after a government report said the economy grew more than expected in the July-September quarter.  Investors shunned Treasuries and jumped back into stocks after the report signaled the economy had emerged from the worst recession since the 1930s. 

The positive surprise was enough to propel benchmark indexes to their biggest advance since July and send safe havens like Treasuries and dollar lower.  Caterpillar Inc. (NYSE:CAT) and Alcoa Inc. (NYSE:AA) advanced at least 5.1% after the Commerce Department said the economy returned to growth following four straight quarters of decline.  Crude prices jumped $2.44, or 3.1%, to $79.87 and gold was up $16.50 to $1046.40.

The S&P 500 registered its biggest one-day gain since July 23, jumping 2.2% to close at 1,066.11.  The 30-share Dow Jones industrial average shot up by 199.89 points, or 2.05%, at 9,962.58 and the tech-heavy Nasdaq Composite index 37.94 points, or 1.84%, to 2,097.55.  The advance was broad-based on the New York Stock Exchange where advancing issues ran ahead of those that declined by a five-to-one margin.  Treasuries also took a beating after an auction of seven-year notes received a weaker-than-expected response.  As the month-end nears, the DJIA has advanced 2.6% in October; the S&P500 0.9%, while the NASDAQ remains 1.2% lower for the month.

A lackadaisical third-quarter performance from Exxon Mobil (NYSE:XOM) could not dampen the mood either and the company’s shares edged up 0.16%.  Procter & Gamble (NYSE:PG), also a Dow component, reported weaker quarterly earnings but revenue was above expectations. The consumer products maker also raised the low end of its fiscal 2010 earnings forecast and its shares rose 4%.

Twenty-eight of the DJIA’s 30 components finished higher while all ten industry sectors of the S&P500 rose during the day, led by advances in basic materials (+4.1%), financials (+3.9%), oil and gas (+2.4%), consumer services (+2.4%), and industrials (+2.2%). 

Among financials, MetLife Inc. (NYSE:MET) jumped 7.9% to $36.84 ahead of its earnings report.  After the close, the biggest U.S. life insurer reported estimate-topping third-quarter operating earnings of 87 cents a share.  Lincoln National Corp. (NYSE:LNC) surged 14% to $25.34 after it reported first quarterly profit in a year that was also ahead of estimates.

Meanwhile, the International Monetary Fund sharply boosted its outlook for Asian economic growth. The IMF also raised its next year’s guidance.  The IMF now expects economic growth of 2.8% this year and 5.8% next, up from last May’s estimates for 2009 growth of 1.2% and 2010 growth of 4.3%.

Firms reporting their earnings include: Chevron (NYSE:CVX), Duke Energy (NYSE:DUK), Sony (NYSE:SNE), and Weyerhaeuser (NYSE:WY).
