Sour Consumer Data Sends Stocks LowerSour Consumer Data Sends Stocks Lower

A study that showed a drop in consumer sentiment was among the factors driving down all of the major indexes on Friday. But for the week, only the tech-heavy indexes lost ground gained from recent rallies.

Although economists had forecast a rise in the University of Michigan index of consumer sentiment, it fell to 87.2 in June from 92.1 in May. The reading on consumers' outlook for the economy's future slumped to 84.2 in June from 91.4 in May, suggesting that Americans are finding it hard to sustain the optimism that followed the end of the Iraq war. Consumer confidence is viewed as a precursor to consumer spending, which drives two-thirds of the U.S. economy.
