(Reuters) - Wall Street shed some of its early gains on Tuesday as U.S. crude prices fell, cutting short a rally inspired by raised hopes for more stimulus measures in China and earnings reports in the United States.
China's growth in 2015 was the slowest in 25 years, in line with expectations, as rattled investors continue to worry about Beijing's ability to manage the economy.
The slowdown in China has resulted in a rout in commodity prices, with oil sliding below 12-year lows.
Oil prices diverged on Tuesday - Brent was up, while U.S. crude was down, pulling down energy and materials stocks.
The market is being led by a combination of earnings reports and technical factors, said Jeff Powell, managing partner of Polaris Greystone Financial Group in California.
"From a technical perspective, we are at a level which if we don't hold, we're in big trouble and even decent earnings are probably going to be overlooked," Powell said.
The S&P 500 has fallen about 12 percent from its high in May, pushing it into what is generally considered "correction territory." On Friday, it sank to its lowest since October 2014.

Bank of America reversed course to trade down 2.8 percent at $14.05 despite beating fourth-quarter profit expectations, after it expressed concerns about weak oil prices.
Morgan Stanley barely held on to its gains, up 0.8 percent at $26.19, after reporting better-than-expected profit.
UnitedHealth was up 2.9 percent at $112.47, giving the biggest boost to the Dow, after the health insurer reported a 30 percent rise in quarterly revenue.
Macy's was up 4 percent at $39.35 after David Einhorn's Greenlight Capital reported a stake in the department store operator.
