BUILDING MOMENTUM: Most commodities rallied for a second day as more proof emerged that the U.S. economy was gaining momentum. Prices for metals, wheat, beans and most energy products rose.
THE IMPETUS: Investors were encouraged by an improvement in orders for long-lasting manufactured goods, which could improve demand for industrial metals like copper, platinum and palladium. But a primary driver of the rally was the Fed's decision to extend its low-interest rate policy.
GAS BLUES: Natural gas prices fell 4.2 percent after the government said U.S. supplies were well above what is normal for this time of year.
