NEW YORK (CNNMoney) -- Good economic news is once again putting pressure on the stock market as investors brace for the Federal Reserve to begin dialing down its stimulus.
The Dow Jones industrial average, the S&P 500 and the Nasdaq were all down Thursday afternoon. The Dow and S&P 500 have fallen for the past four trading days and appear to be on track for their fifth consecutive day of losses.
The government revised its initial report on third-quarter economic growth to 3.6%, up from the previous estimate of 2.8%. The improvement was largely driven by inventory growth as companies restocked their shelves ahead of the holiday shopping season.
And the number of Americans filing first-time claims for unemployment benefits fell more than expected last week, the Labor Department said. Economists said the decline may have been distorted by the Thanksgiving holiday.
But the upbeat economic numbers failed to give the market a lift. Many investors believe that good economic news makes it more likely that the Federal Reserve will begin scaling back, or tapering, its monthly bond purchases.
The yield on the 10-year Treasury rose to 2.86% after the economic reports were released. Bond yields rise when prices fall. So bond investors are selling Treasuries in anticipation that the Fed may no longer buy as much going forward.
The Fed's $85-billion per month bond buying program has helped fuel the bull market since March 2009. But the central bank signaled earlier this year that it hopes to gradually reduce the purchases as the economy recovers. It has said that improvement in the job market could trigger this process.
The government's November jobs report is due Friday. Economists surveyed by CNNMoney expect that report to show 183,00 jobs were added last month.
But not everyone is convinced the Fed will taper at its next policy meeting -- which wraps up on December 18. Alastair McCaig, market analyst for IG in London, said the holiday shopping season would be "a fragile time of year" for the Fed to pull back on its bond purchases.
"Trying to squeeze something in before the end of the year would start a little bit of panic, the tail end of December being just an incredibly important retail period," he said. "It would be a little bit dangerous to do something this year."

J.C. Penney shares were down nearly 10%, extending Wednesday's losses as investors worry about the retailer's turnaround plan.
