Wall St Week Ahead - A burst of energy with Exxon, Chevron on tap

NEW YORK: Since late February, when investors fell out of love with biotechnology and other high-flying stocks, the market's fuel has been oil.

Energy names have been the best-performing sector in the S&P 500 since Feb. 25 when the selloff in high-growth stocks began. The sector will look to build on recent gains when bellwethers Exxon Mobil Corp, Chevron Corp and ConocoPhillips report results next week.
