Stocks suffered a big loss on the last day of April as investors showed their disappointment with two economic reports and worries about a criminal investigation of Goldman Sachs. But the major indexes still had their third straight monthly gain.

Investors lost some of their optimism about the economy Friday after the government's weaker-than-expected gross domestic product report and news of a drop in consumer sentiment. Reports that the government has started a criminal investigation of Goldman sent financial stocks tumbling. Investors feared that possible charges against the company could have a chilling effect on the banking industry.

The Dow Jones industrial average fell 158 points, and all the major indexes fell more than 1 percent. The Dow rose 1.4 percent for April, but it snapped an eight-week winning streak.
