Concerns about another terrorist attack and a still-sluggish economy sent stocks lower Friday, pushing the major averages down for a fourth-straight week.


Dow Jones Industrial Average

ended down 65 points, or 0.8%, at 7864, while the


finished down 19 points, or 1.5%, at 1282. The

S&P 500

fell 8 points, or 1%, to 829. For the week, the Dow lost 2.3%, while the S&P fell 3% and the Nasdaq shed 2.8%.

"To call the investment community jittery and unsure at this time is nothing but a huge understatement," said David Skarica, editor of the newsletter Addicted To Profits. "Currently, it is the most dangerous time in the last five years to be invested in the market."

The Bush administration raised the national terror alert to orange from yellow Friday to indicate a high risk of a terrorist attack. The government said it has received indications that al Qaeda may be planning attacks on U.S. targets in mid-February and has ordered security to be tightened at major bridges and tunnels as well as ports, railroads and nuclear power plants.

Meanwhile, analysts and investors ignored January's employment report, which seemed to suggest that the labor market could be stabilizing.

"The reality is, the economy is still weak," said Donald Straszheim, president of Straszheim Global Advisors. "Twelve months into the recovery, jobs are down 0.1% versus a postwar average of +3.3%. The only weaker recovery was after the 1990-91 recession."

The unemployment rate fell to 5.7% in January from 6% in the prior month as the economy added 143,000 nonfarm jobs. That was the strongest job growth since November 2000 and easily exceeded consensus expectations, which called for 69,000 jobs to be added to the payroll. Analysts had expected the jobless rate to remain steady at 6%. In December, 156,000 jobs were lost.

"The bigger picture is that a net 13,000 jobs have been lost over the past two months," said David Rosenberg, chief economist at Merrill Lynch.

Rosenberg, like other economists, argued that the January data are misleading because of seasonal adjustments. He claims that because fewer retail workers were hired ahead of the holidays, fewer were let go in January. About two thirds of the job growth came from the retail sector, but excluding jobs in that area, the economy added just 42,000 jobs.

In addition, the government changed its methodology of calculating the household survey, which means that the January employment rate is not directly comparable with earlier data. Still, the report did seem to show that things aren't getting any worse.

"Overall, the report supports the view of a plodding, but still improving economy. It does not signal a sudden, dramatic turnaround," said Bill Cheney, chief economist at John Hancock Financial Services.

Separately, wholesale inventories rose 0.8% in December, above the 0.2% consensus estimate.

Concerns about the likelihood and timing of war with Iraq also added pressure Friday after President Bush said Thursday night that "the game is over" and Secretary of State Colin Powell said the crisis will reach a conclusion "within weeks." Crude oil hit a three-week high of $35 Friday.

"Until we get some resolution on the geopolitical issues, you're going to continue to see these false starts," said Joe DeMarco, head trader at HSBC Asset Management. Stocks opened higher Friday before quickly paring their gains.
