Blue-chips couldn't hold their gains Thursday, despite positive economic news and solid profit reports from the retail sector, and tech stocks closed lower after being pressured by weakness in the chip sector.

The

Dow Jones Industrial Average finished with a loss of 21.45 points, or 0.2%, to 10,106.13. The

Investors had plenty of positive news to sift through, particularly on the economic front, but it wasn't enough to give buyers the edge by the time the market closed. The Chicago purchasing managers' index rose to 53.1 in February from 45.1 in January, its highest level since June 2000. The government also revised its estimate of fourth-quarter

gross domestic product growth to 1.4% from 0.2%, higher than the 0.9% estimate.

Meanwhile, the Labor Department said initial jobless claims rose to 378,000 in the week ended Feb. 23 from a revised 361,000 the previous week. Economists were expecting the number of first-time claims to rise to 385,000.

Late in the day, terrorism fears resurfaced. According to televised reports, Canadian fighter jets were shadowing an Air India flight bound for New York's John F. Kennedy International Airport because of concerns that a passenger on the plane might be on a terrorist watchlist.

Retailers continued to report their quarterly earnings this week, and many of the results were better than expected, but chain-store operators are generally adopting cautious stances on their near-term outlooks.
