Stock futures pointed slightly higher Friday after major indexes set new closing records, as investors continue to downplay the U.S. government shutdown, now in its third day. Yesterday, stock indexes ended higher for a fifth straight session, with the tech-heavy Nasdaq, blue-chip Dow Jones Industrial Average, and benchmark S&P 500 ending up 0.4%, 0.2%, and 0.1%. It was the second day in a row that the Dow and S&P 500 set new closing marks, while the Nasdaq and S&P 500 also hit intraday records. Futures associated with all three indexes were up roughly 0.1%, with chip stocks again leading the advance. Gold futures, which set their latest record high early yesterday before retreating, advanced 0.4% to $3,880 an ounce.
