US stocks closed with solid gains Tuesday as the country went to the polls to choose between Barack Obama and Mitt Romney for president, with the economy the key issue in the tight election. The Dow Jones Industrial Average added 133.24 points (1.02 percent), closing at 13,245.68. The broad-based S&P 500 rose 11.13 (0.79 percent) to 1,428.39, while the Nasdaq Composite climbed 12.27 (0.41 percent) to 3,011.93. Wall Street has been more behind the president\'s Republican challenger Romney, who supports low investment-related taxes. But most in the business world want a clear decision that will allow the government to move on fixing the extremely austere \"fiscal cliff\" legislation that comes into play at year end. \"The presidential race is considered too close to call. That probably means the nation is in store for a long night of political intrigue,\" said Patrick O\'Hare of Briefing.com. \"Let\'s hope, however, that by this time tomorrow we at least know who has been elected president. There is a risk that we won\'t and that won\'t be a good thing.\" Hewlett-Packard led Dow gainers, up 2.8 percent, followed by United Technologies, up 2.7 percent. Charles Schwab & Co. analysts underlined a sharp rally in oil prices that stoked buying. \"The bulls found some support from energy issues as crude oil prices rallied,\" they said. Dow oil giant members Chevron and ExxonMobil each added 1.1 percent.

Zillow, the online real-estate information company, plunged 18.1 percent after reporting a better-than-expected profit for the third quarter but forecasting fourth-quarter revenue below estimates.
