The month of March turned out to be pretty good for stocks, capping an even better performance for the first quarter. The Dow Jones Industrial Average advanced 1% in March and 3.7% in the first three months of 2006. The S&P 500 rose 1.1% for the month and 3.7% for the first quarter. The Nasdaq Composite performed the best, advancing 2.5% in March and 6% over the past three months. This was the best first quarter for the S&P 500 since 2000, according to Bloomberg. The energy and materials sectors were the best performers of the broad index, closely followed by the telecom sector. Amid end-of-quarter portfolio adjustments on Friday, the Dow fell 41 points, or 0.37%, to 11,109, the S&P fell 0.4% to 1294 and the Nasdaq dropped 0.04% to 2339. The market's performance was mixed for the week, as investors digested another hike by the Federal Reserve on Tuesday and signals of more to come. The Dow dropped 1.5% and the S&P fell 0.6%, but the Nasdaq climbed 1.2% on the week. The Nasdaq was boosted this week, in part, by strength in Google ( GOOG) early in the week in anticipation of the Internet search giant's inclusion into the S&P 500 on Friday. Still, Google dropped 5.8% in the quarter after hinting in early March that its profits wouldn't rise exponentially forever. In other corporate news, bankrupt auto-parts supplier Delphi is seeking to void its labor contract with the United Auto Workers, after the union rejected Delphi's demands to cut wages and benefits. Delphi also said it would seek to shed "unprofitable" supply contracts it currently has with General Motors ( GM). GM still rose 1% on the day. The stock market might relax a little with the next Fed meeting six weeks away and the first-quarter earnings season just a few weeks away. "We're not going to feel the impact of these rate hikes for quite some time," says Marc Pado, market strategist at Cantor Fitzgerald.
