Energy, materials stocks drive Wall Street rally

Wall Street was higher on Monday as prices of oil and other commodities surged, pointing to an uptick in investors' risk appetite following a rout in global markets. The recovery in commodity prices comes on the heels of recent data pointing to a strengthening of the U.S. economy, which has helped stabilize the market. The S&P 500 has risen 4.1 percent in the past five days, including Monday's gains, spurred by better-than-expected jobs and inflation data.
