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.

"My pick for an Obama victory would be Cosan (NYSE: CZZ), a major Brazilian maker of ethylene from sugar; the company should benefit as the U.S. expands its use of alternative fuels," says Vivian Lewis, editor of Global Investing.

"Cosan will benefit from growing world demand for sugar. But it is also an alternative energy play because Brazil leads the world in production and distribution of ethylene, a policy undertaken after the first oil price shock of 1974.

"Obama is not happy with U.S. dependence on OPEC oil imports; and, obviously, the Brazilians are much less of a threat to our values, with the country now a democracy with free elections and a rather liberal economic policy.

"The U.S. ethylene market currently remains closed to Brazilian exports as we try to making the stuff from corn. But some of that nonsense may not survive.

"If the U.S. is serious about alternative fuels, then these alternative fuels should be as easy to import to the U.S. as crude oil, if not easier. After all, Brazil does not finance terrorists.

"While many have been focused on the falling price of oil, I forecast that the price drop will soon reverse.

"Meanwhile, the London-based International Sugar Organization says regardless of what happens to the world economy, demand for sugar will exceed supplies this year for the first time since 2006.

"Brazil is the world's top sugar producer, and it will use 56% of its production to make ethanol. Cosan management says they plan to increase production and expect the strengthening dollar to give an extra boost to earnings.

"In my view, Cosan is cheap. The stock was recently trading at half its 12-month high. It already ships its ethylene and sugar diesel fuel to European markets, which are more sensible about encouraging alternatives than is our current government in Washington."
