Reuters - U.S. stocks rebounded on Tuesday after Pfizer's upbeat results gave investors some relief from the pain of the Dow's five-day losing streak, and the market's focus turned to the Federal Reserve's next move on stimulus.

The market's advance, which also broke the S&P 500's three-day slide, came after heavy losses tied to concerns about the withdrawal of U.S. monetary stimulus as well as worries about emerging markets, including a slowdown in China's growth and political turmoil from Turkey to Thailand. Last week, the S&P 500 marked its worst percentage loss since June 2012.

After the close, U.S. stock index futures rallied after Turkey's central bank sharply raised its interest rates, giving further relief to investors. S&P 500 e-mini futures shot up 20 points on volume of 1.7 million contracts.

Bucking the day's trend, the stock of Apple Inc dropped 8 percent to close at $506.50 - its worst slide in a year - a day after holiday iPhone sales missed expectations. Apple's slide limited the gains of the S&P 500 and the Nasdaq.

Shares of Pfizer Inc jumped 2.6 percent to close at $30.42, boosting both the Dow and S&P 500 after the biggest U.S. drugmaker reported a better-than-expected quarterly profit.

"It's a reflex rally. It just technically looked deeply oversold, so it was bound for a small short relief rally," said Fred Dickson, chief market strategist at D.A. Davidson & Co. in Lake Oswego, Oregon.

The Dow Jones industrial average rose 90.68 points or 0.57 percent, to end at 15,928.56. The S&P 500 gained 10.94 points or 0.61 percent, to finish at 1,792.50. The Nasdaq Composite added 14.35 points or 0.35 percent, to close at 4,097.96.

The S&P 500 remains below its 50-day moving average, after closing below it on Friday for the first time since Oct. 9.

A bright spot in the day's economic data was a report showing U.S. consumer confidence rose in January. Consumers grew more optimistic about both business conditions and the job market, according to the Conference Board.

But orders for long-lasting U.S. manufactured goods unexpectedly fell 4.3 percent in December, and a gauge of planned business spending on capital goods also slid, which could cast a shadow on an otherwise bright economic outlook.

The data preceded the start of the Fed's two-day policy meeting. Investors are anxious to hear whether the Fed will cut another $10 billion from its monthly bond-buying program. In December, the central bank announced plans to scale back its stimulus.

Recent soft economic data coupled with equity selling in the United States and abroad may have some participants rethinking what the Fed will do next.

"Perhaps there is a growing collection of wisdom (that) the Fed may postpone its tapering," said Mark Luschini, chief investment strategist at Janney Montgomery Scott in Philadelphia.

Apple shares fell to their lowest since October. The tech bellwether's iPhone sales in the holiday shopping season missed lofty expectations and the company forecast weak revenue for the current quarter in its quarterly results.

After the bell, shares of audio chipmaker Cirrus Logic Inc , an Apple supplier, fell 4.6 percent to $17.87 as it forecast fourth-quarter revenue far below Wall Street's estimates. In the regular session, Cirrus shares declined 4.5 percent to end at $18.74.

During the regular session, activist investor Carl Icahn said he bought another half-billion dollars' worth of Apple stock, his third investment in the iPhone and iPad maker in less than a week. The purchase increases his stake to more than $4 billion.

In another snapshot of the economy, U.S. single-family home prices in November rose slightly more than expected from the previous month, while the increase from a year ago was the biggest in almost eight years, a closely watched survey showed.

Volume was slightly below average for the month. About 6.6 billion shares changed hands on U.S. exchanges, compared with the average of 6.9 billion so far this month, according to data from BATS Global Markets.

Advancers outnumbered decliners on the New York Stock Exchange by about 3 to 1. On the Nasdaq, two stocks rose for every one that fell.
