After two weeks of strong earnings pumped up the U.S. markets, weak results from Pfizer and others deflated a broad earnings rally, at least for today.

The world's largest drug maker posted lower than expected quarterly results Tuesday, slowing a parade of positive corporate reports. Clorox, Molson Coors Brewing Co., and Beazer Homes also slipped after announcing weaker earnings.

That sent broad indexes such as the Standard & Poor's 500 lower. The Russell 2000, an index of small companies, lost 1.3 percent.

The S&P 500 fell 4.60 points, or 0.3 percent, to 1,356.62. The Nasdaq composite fell 22.46, or 0.8 percent, at 2,841.62. The Dow Jones industrial average inched out a gain of 0.15 percent to close at 12,807.51.

Randy Bateman, chief investment officer and president of Huntington Asset Advisors, said some kind of weakness was natural following a mostly positive earnings season. About 65 percent of companies in the S&P 500 have reported their results, and earnings are up about 21 percent from the same period last year, according to FactSet.

"We've had such a strong, hard run for the entirety of the year in the face of an awful lot of adversity," Bateman said. "Investors are going to sit back a little bit and say, 'How much more good news is out there?'"

Pfizer Inc. fared worst in the Dow Jones industrial average Tuesday, losing nearly 3 percent after the company reduced its revenue forecast for 2011.

Clorox Co. fell 3.6 percent and Molson Coors Brewing Co. fell nearly 6 percent after each reported lower net income compared to the same period last year. The consumer goods maker and beverage company both blamed higher costs for raw materials for the decline.

Beazer Homes USA Inc. slipped 5 percent. The homebuilder reported a larger-than-expected loss because orders for new homes fell, reflecting continued weakness in the housing industry.

The losses came after a string of stronger than expected earnings reports pushed the broad stock market up 2 percent this quarter. The Dow Jones industrial average gained 2.4 percent last week alone.

"You get a nice move like that and you're bound to have a pullback," said Bill Stone, chief investment strategist at PNC Asset Management. Investors sold stocks based on their perceived riskiness, he said, with the stable companies in the Dow losing the least and smaller, riskier companies in the Russell 2000 declining the most.

Not every company had poor results. MetroPCS Communications Inc. rose 10 percent, the most of any company in the S&P 500, after it added a record number of subscribers in the first quarter. The company sells low-cost phone service, primarily in cities.

Quotes delayed 15+ min.

General Motors rose 2.5 percent after its U.S. car and truck sales jumped 26 percent in April. Higher gas prices motivated consumers to buy more fuel-efficient vehicles.

Bond prices rose slightly. The yield on the 10-year Treasury note dipped to 3.26 from 3.28 percent from late Monday.

Two stocks fell for every one that rose on the New York Stock Exchange. Consolidated volume came to 4.5 billion shares.
