Stocks were moderately lower Friday after strong advances all week and after the Commerce Department reported that housing construction fell to its lowest level in more than six years. The modest pullback follows five straight sessions of advances for stocks during which the Dow Jones industrials this week logged three consecutive record closes. Heading into Friday's trading, the major indexes were up at least 1 percent for the week, with the Nasdaq leading the way with a gain of nearly 2.5 percent. Nov. 17, 2006
