Institutions have notched solid stock gains over the past 4-6 months and some investors, particularly those with short-term models, may decide to take some of those gains prior to the job report, as a way to protect those profits in the event of a market sell-off if the employment data is worse-than-expected. Economists surveyed by Bloomberg News forecast that the U.S. economy lost 175,000 jobs in October – an improvement from the off-the-table, gargantuan monthly job losses recorded during the financial crisis' acute stage earlier this year, but still a large monthly job loss. The U.S. economy lost 263,000 jobs in September and has lost more than 7.2 million since the recession started in December 2007.

Also in September, the U.S. unemployment rate increased to 9.8% from 9.7% in August; economists surveyed forecast the rate to rise to 9.9% in October.

Further, a September job loss total higher than 250,000 will spark renewed concern about a possible double-dip recession - and a double-dip recession and Dow 10,000 are not compatible, to say the least.

Hence, don't attach too much significance to U.S. stock market dips prior to Friday, as a portion of it is profit-taking and positioning ahead of the jobs statistic.

After the September payroll data is released on Friday at 8:30 a.m. EST, the Dow's level will be more-telling, as investors will have a better idea concerning whether the nation is winning the battle against job losses, or if even more public policy action is needed to help end the nation's longest and worst job drought in more than 25 years.
