This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"If Barack Obama wins, look to AeroVironment (NASDAQ: AVAV), a company involved in both unmanned aerial vehicles (UAVs) and alternative energy solutions," says tech and science expert Gregg Early, editor of The Real Nanotech Investor.

"For Baby Boomers or aviation fans, the founders of the company were the people that brought us the Gossamer Albatross in the 1970s, a human powered plane that flew over the English Channel.

"The company that formed from Dr. Paul MacCready's fascination of manned flight eventually transitioned into a business that focused on unmanned flight, more precisely unmanned aerial vehicles (UAVs).

"This work on UAVs made the company a long-time partner with NASA in developing the concept of unmanned aviation.

"When 9/11 came, and we set off to war and birthed the Department of Homeland Security -- the largest agency built by the government since the Department of War -- UAVs became one of the hottest sectors in the armed force and homeland security.

"AeroVironment started getting a lot of those orders. What's more, the company has two other divisions.

"One focuses on 'architectural wind' power for urban settings. The other focuses on industrial/consumer electric vehicle charging systems as well as solar pump controllers that use solar power to pump water, run water purification, etc. in remote areas.

"Between next-generation defense products and alternative energy solutions, this company will doubly benefit from a president focused on technology and innovation to secure the U.S. competitive position in the world again."

Also, Peter Cohan points out that a bear market means low earnings expectations, and also that negative surprises are likely to outweigh positive ones in the second half of the year. Aaron Katsman, on the other hand, predicts a rebound for earnings in the second half. And BusinessWeek reminds us that cheap stocks -- even with big names such as Ford Motor Co. (NYSE: F), Sprint Nextel Corp. (NYSE: S), and Northwest Airlines (NYSE: NWA) -- are no bargain if they have no earnings.

Upcoming results to watch for include Alcoa (NYSE: AA), Pepsi Bottling Group (NYSE: PBG), Marriott International (NYSE: MAR), and General Electric (NYSE: GE).
