Blue-chip stocks crawled past the 10,000-point line to put another brave face on the limping economy.

The 30 companies in the Dow Jones industrial average now have a market value of nearly $3.3 trillion, but analysts caution that it’s not a reliable gauge of recovery from the two-year recession.

“It’s a psychological barrier and will draw in some retail investors, but it doesn’t carry that much significance with people in the professional investing community,” said strategist Robert Pavlik at Banyan Partners.

The rally came ahead of today’s important jobs report, which offers a more accurate read on the economy.

Analysts expect the jobless rate to inch up to 9.9 percent for October from 9.8 percent in September. Some economists see the unemployment rate rising by next summer to as high as 10.5 percent.

Government reports yesterday showed a slowdown in claims for unemployment checks and a sharp 9.5 percent jump in the productivity of workers who are still employed at trimmed-down factories.

“We believe businesses will have to start to increase hours worked and payrolls around the turn of the year, since they cannot expect their current work force to sustain such rapid productivity growth,” said Michelle Meyer, an economist at Barclays Capital.

That sentiment helped send the Dow jumping 203.82 points, or 2.1 percent, to 10,005.96. The Standard & Poor’s 500 index rose 20.13, or 1.9 percent, to 1,066.63, its fourth straight gain. The market value of S&P stocks is $9.5 trillion, nearly three times the value of the blue-chips list.

The Nasdaq rose 49.80, or 2.4 percent, to 2,105.32, its biggest gain since July 23. Its market value is $3.4 trillion.
