The premarket selloff in International Business Machines Corp.'s stock can be blamed for the decline in Dow Jones Industrial Average futures ahead of Tuesday's open. IBM's stock slumped $7.18, or 4.8%, ahead of the open, after the technology company missed third-quarter revenue expectations and cut its full-year profit outlook. That decline would shave off about 48 points from the Dow . Meanwhile, Dow futures were down 20 points. Shares of fellow Dow components Travelers Companies Inc. gained $2.80, or $2.6%, and Verizon Communications Inc. tacked on 55 cents, or 1.2%, in premarket trade after third-quarter results, which would add a combined 22 points to the Dow, not enough to offset IBM's decline.
