"They don't want to send the wrong signal. They don't want to spook the markets. I think they'll be a little more bullish on the labor markets but they'll pivot to inflation. They'll be more worried about inflation," said Diane Swonk, chief economist at Mesirow Financial. "The markets seem pretty well prepared. The Fed has prepared them for tapering."
The focus now will be the Fed's still long path toward raising the fed funds rate from zero, where it's been since 2008. But the Fed is not likely to give any clues Wednesday about when that could start even though its forecasts show a possible midyear start date, versus the market's expectations the first hike will not be until the fourth quarter of next year.
While the Fed is expected to attempt to be market neutral in its 2 p.m. statement Wednesday, it may be that some of the reaction to the end of QE already was thrashed out when markets reacted to global growth concerns and Ebola earlier this month. The stock market has been rebounding, recovering nearly all its losses, and the Dow and S&P 500 are both less than 2 percent from all-time highs. The S&P lost 9.8 percent from mid-September to mid-October.

Bond yields in October carved out a new lower range, and expectations for yields have been reset to lower levels across Wall Street. Besides keeping short-term rates low, Fed watchers say it hopes to suppress longer term rates with the huge amount of bonds it holds on its more than $4.4 trillion balance sheet. The 10-year yield was at 2.29 percent Tuesday.
Stocks rallied Tuesday, shrugging off weaker durable goods orders, and focused instead on better earnings and a sharp jump in consumer confidence. The Dow was up 187 points to 17,005 and the S&P 500 was up 23 at 1,985, above its 50-day moving average. The small-cap Russell 2000, which has been lagging, jumped 2.9 percent.
Swonk also expects the Fed to remain open to another round of quantitative easing even though it wants the program to end. "They have to leave the door open to QE4, but they really don't want to do it. One of the things they made clear is they want the balance sheet steady. Is it the flow or the stock? They made clear they want to keep the balance sheet steady until they start raising rates," Swonk said. The Fed currently purchases assets to make up for those that mature, and that practice is expected to continue.
Janney Montgomery chief investment strategist Mark Luschini said the markets will be looking to see if the comments made by St. Louis Fed President James Bullard earlier this month are reflected in the statement. Bullard, at a time when markets were wavering, said the Fed could move away more slowly from QE if there was too much market turbulence, a comment that sparked a stock rally.
While unlikely, "that would be a boost to equity prices," Luschini said, adding that the end of QE should not move the market, as it is expected. "That's got to be well discounted at this point in time. If they dropped the 'considerable time,' that would be a big deal and that would be interpreted as hawkish," he said.
