Wall Street stocks drifted lower Tuesday after data showed a slight dip in US consumer spending as well as a fall in factory orders and pending home sales. The Dow Jones Industrial Average fell 38.00 points (0.36 percent) to 10,636.38, after jumping more than 200 points a day earlier. The tech-rich Nasdaq composite index declined 11.84 points (0.52 percent) to 2,283.52 while the broader S&P 500 index lost 5.40 points (0.48 percent) at 1,120.46. The market sentiment was dampened by 'flat consumer income and spending, exacerbated by a much larger-than-forecasted drop in factory orders and an unexpected drop in pending home sales,' analysts at Charles Schwab & Co wrote to clients. Disappointing quarterly earnings of behemoths such as Dow Chemical and Procter & Gamble also soured market sentiment. The market digested a host of economic data, including a fall in consumption expenditures by less than 0.1 percent compared with a similar percentage rise in May, according to the government. Consumer spending is a key driver of US economic growth, usually accounting for two-thirds of output. US factory orders also slumped in June, declining for a second consecutive month, the Commerce Department said. Adding to the bearish news was a report by the National Association of Realtors showing the number of contracts signed to purchase existing US homes unexpectedly falling to its lowest level in nine years. The association's pending home sales index declined 2.6 percent to 75.7 points based on contracts signed in June compared to the earlier month.
