Energy giants such asBP ( BP ),ConocoPhillips ( COP ) andChevron ( CVX ) are making deep job and spending cuts. "It's a market that's reacting emotionally," John Love, CEO of United States Commodity Funds, told IBD in a phone call Wednesday, a day after U.S. crude fell below $30 for the first time in 12 years. Commodities serve as a powerful inflation hedge, trade differently than stocks and bonds, offer low correlation among one another, and enhance returns with lower volatility over the long term, according to Love.
