"DataBank; A Mixed Week, but a Strong Quarter for Stocks" "The broad stock market gave up ground last week on concerns about inflation and interest rates, but the technology-dominated Nasdaq composite index rallied. For the first quarter, which ended Friday, all three major indexes posted substantial gains. On Tuesday, Federal Reserve policy makers raised their benchmark short-term interest rate to 4.75 percent, the 15th consecutive increase. A statement at the end of the meeting indicated that the Fed would be ready to raise rates again if needed to contain inflation. This set the markets back. Alcoa, the aluminum producer, gained 2.5 percent for the week, the best performance in the Dow. Shares of Google rose 6.6 percent for the week, among the best performances in the Nasdaq. Google said on Friday that it had raised $2.07 billion in its second stock sale. For the week, the Dow Jones industrial average lost 170.65 points, or 1.5 percent, to close at 11,109.32. The Standard & Poor's 500-stock index fell 8.12 points, or 0.6 percent, to close at 1,294.83. The Nasdaq composite index gained 26.97 points, or 1.2 percent, to close at 2,339.79. The yield on the 10-year Treasury note rose to 4.85 percent from 4.66 percent the previous week. JEFF SOMMER"
