U.S. stocks are flipping from slight gains to losses in midday trading. According to AP, the Dow Jones industrial average was up five points to 14,402 shortly before noon on Monday. That modest climb puts the index on track for its seventh straight day of gains. Boeing led the Dow up, rising 1 percent. The Standard & Poor's 500 fell one point to 1,551. The index is 14 points below the record high it reached in October 2007. The Nasdaq composite fell four points to 3,240. The economic calendar is light on Monday, offering investors little to latch on to. The Dow blew past its record high from October 2007 last Tuesday. It set records the rest of the week and ended up 2 percent.
