Over the past few weeks, fluctuating polls have shown that Donald Trump has narrowed Hillary Clinton's lead, improving his odds of becoming president. As the presidential race hurdles towards the November finish line, a few stocks stand out as potential winners if Trump is elected.

In general, energy and military-based companies stand the best chance of substantial gains. Under a Trump presidency, coal industries, for example, would avoid the substantial hit from Clinton's promise to close down plants and enact stricter regulations. In addition to coal and oil stocks such as Cloud Peak Energy Inc. (NYSE:CLD), Halliburton Company (NYSE:HAL), and Continental Resources, Inc. (NYSE:CLR), companies that provide for military, including Northrop Grumman Corporation (NYSE:NOC) and Lockheed Martin Corporation (NYSE:LMT), will also benefit.

With Trump's vow to rebuild the American military, such industries should expect a surge of government funding should he become president. In fact, a closer look reveals that Lockheed Martin Corporation is a solid investment regardless of who ends up in office. The company's outlook is bullish, with many seeing a target of $263 per share. Since the previous quarter, the database has seen an increase of two funds for Lockheed Martin, up from 37. Overall, analysts predict a 20% growth of earnings each year up through 2020 at the least.
