The bull market took a breather on Tuesday, with stocks retreating from their recent highs.
Overall, the S&P 500, Dow and Nasdaq are all up more than 20% in 2013, thanks to a slowly recovering economy and continued bond buying from the Fed.
Investors are fixated on one question: When will the Federal Reserve be ready to start slowing its stimulus program?
Stronger-than-expected reports on economic growth and the job market have led some economists to expect the Fed to announce it will slow its stimulus program at its next meeting in December.
"The market is basically doing pretty good, considering that tapering is back on the table," said Peter Cardillo, chief market economist at Rockwell Global Capital.
Investors previously thought the Fed may wait until the spring to taper. But now that some think the Fed could pull back as soon as next month, interest rates are rising again. The benchmark 10-year Treasury yield temporarily hit 2.78% Tuesday morning -- its highest level in about two months.
Minneapolis Fed President Narayana Kocherlakota and Atlanta Fed President Dennis Lockhart both argued in speeches Tuesday afternoon that the Fed still needs to do more to aid the job market.
"The labor market remains disturbingly weak," Kocherlakota said. "The good news is that, with low inflation, the FOMC has considerable monetary policy capacity at its disposal with which to address this problem."
Kocherlakota is scheduled to rotate into a voting role on the Fed's policymaking committee in January.
