NEW YORK ( TheStreet) -- Stock futures were holding onto gains Tuesday as investors looked to the U.S. presidential election and cheered better-than-expected earnings reports from companies such as AOL ( AOL) and CVS Caremark ( CVS). Investors also will be keeping a close eye on the U.S. congressional races, with the results particularly important in connection with handling the looming fiscal cliff. With many expecting Congress to remain divided, economists at Bank of America are anticipating "a prolonged negotiation process" on this issue. Futures for the Dow Jones Industrial Average were rising 32 points, or 36.56 points above fair value, at 13,085. Futures for the S&P 500 were up 4.8 points, or 4.34 points above fair value, at 1416. Futures for the Nasdaq were up 11.25 points, or 6.29 points above fair value, at 2673. "Equity markets in presidential election years do not follow a consistent pattern like markets in midterm election years. However, median equity performance in the weeks following very competitive elections slightly outpaces performance following less competitive contests," Jan Hatzius, chief U.S. economist at Goldman Sachs, said in a note. "That said, this election is unusual in that it will be immediately followed by debate on the fiscal cliff, and thus resolution of the election will reduce, but not eliminate, policy uncertainty." Hatzius cautioned that "given that pre-election polling indicates that, at least at a national level, this election is closer than most others over the last 50 years, there is a clear risk that the results may not be known by the end of Nov. 6." The most recent polls suggest that President Barack Obama has a slight lead over Republican candidate Mitt Romney in major swing states. "A Democrat victory in the Senate will mean another divided Congress that may once again descend into partisan bickering with little or nothing to show for it. If the sun shines on the Republicans, however, the GOP will control Congress and be able to usher through their legislative favorites," noted noted Doug Cote, chief market strategist at ING Investment Management. Overseas markets were trading mixed Tuesday. The FTSE 100 in London was rising 0.54%, while the DAX in Germany was gaining 0.44%, even as concerns about the eurozone flared up again with anxiety about Greece's ability to access more financial aid. Japan's Nikkei average finished down 0.36% and Hong Kong's Hang Seng closed down 0.28%.
