NEW YORK, Jan 10 (Reuters) - U.S. stock index futures rose on Thursday, alongside other risk assets, as stronger-than-expected exports in China, the world's second-biggest economy, raised hopes for a more robust recovery in the global economy this year.
Data showed China's export growth rebounded sharply to a seven-month high in December, a strong finish to the year after seven straight quarters of slowdown, even as demand from Europe and the United States remained subdued.
Adding to the bullish sentiment, Spanish benchmark government bond yields fell below 5 percent to a 10-month low on the back of a strong bond auction that raised more than the target amount.
"The market's more positive and it owes a lot of that to the Chinese economic data," said Art Hogan, managing director of Lazard Capital Markets in New York, adding that the success of the Spanish auction was also of note.
S&P 500 futures rose 4.2 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 25 points, and Nasdaq 100 futures added 5 points.
