For U.S. drivers fed up with the volatility and seemingly annual spring/early summer surge in gasoline prices, there is a way to hedge most of that risk via an exchange-traded fund: the U.S. Gasoline Fund (NYSE: UGA). UGA traded Monday afternoon down 82 cents to $29.95. I haven't mentioned the fund because UGA has less than three year's price history, and, frankly, the economics literature is mixed regarding how effective petroleum funds are at matching (and hence hedging) price rises.
