Updated from 4:09 p.m. EDTStocks fell Friday -- with the Dow closing below 9000 for the first time since June 9 -- as investors took some money off the table amid light volume and a dearth of any market-moving news. The Dow Jones Industrial Average ended down 90 points, or almost 1%, at 8989 while the Nasdaq fell 9 points, or 0.5%, at 1625. The S&P 500 finished with a loss of 9 points, or 0.9%, at 976. All three major averages ended lower for the week. "The news this week has actually been pretty mediocre," said Ed Peters, chief investment strategist at PanAgora Asset Management. "There hasn't been a lot of incentive for people to want to increase their holdings over the weekend." Peters said the market sold off Friday afternoon more because of a lack of buyers than an abundance of sellers. "This is what sometimes happens when you have light volume," he said. Volume on the New York Stock Exchange reached 1.2 billion shares, with losers beating winners by 17 to 15. On the Nasdaq, 1.5 billion shares changed hands with decliners outpacing advancers by 17 to 14. Stocks had been higher earlier although stuck in a tight trading range as investors digested the latest economic data. The University of Michigan consumer sentiment index fell to 89.7 in June from 92.1 in May, as concerns about slow job growth persisted. Still, the final reading was better than the 87.7 level that economists had been looking for. Meanwhile, personal spending rose a slightly-less-than-expected 0.1% in May while personal income climbed 0.3%, in line with economists' estimates. Next week brings a raft of economic data, including the employment report and ISM index for June, and some traders said investors were treading carefully ahead of that news and ahead of any possible preannouncements over the next week or two. After a strong start, Microsoft ( MSFT) retreated and was recently down 0.3%, or 9 cents, at $25.63 after an analyst at CSFB raised the stock's target price to $29 from $27 on expectations the company's upcoming earnings won't disappoint. Although the firm still believes the stock will continue to underperform in the short run, it cited upside potential based on valuation.
