Market diary.

Amid turmoil in Iraq, Wall Street's late March rally petered out as the month ended. Nevertheless, the Dow Jones Industrial Average, Nasdaq composite, S&P 500 and the LABJ 200 Index all finished up for the week ended March 31. The Dow gained 3.1 percent, Nasdaq 4.4 percent, S&P 3.2 percent and the LABJ was up 2.7 percent. The broad S&P 500 ended the quarter in positive territory for the year, up 1.3 percent. The LABJ 200 is up 3.5 percent since Dec. 31. Locally, advances led declines by 140 to 46, with 28 stocks reaching new 52-week highs and only 3 reaching 52-week lows. The top gainer for the week was En Pointe Technologies Inc., an information technology firm that rose 63.4 percent on news of a pact it reached to provide services to the city and county of San Francisco. Among the decliners was Flamemaster Corp., which fell 14.4 percent after announcing a restructuring; and CytRx Corp., which was off 8.9 percent after a 188 percent increase over the past year. Each of the 18 industry sectors in the LABJ 200 were up last week, with the exception of biomedical and pharmaceuticals, which were flat. The software sector gained 14.6 percent.
