NEW YORK, Oct 13 (Reuters) - U.S. stock index futures fell on Thursday after earnings from JPMorgan Chase and weaker-than-expected economic data in China reawakened worry about a slowing global economy.

JPMorgan Chase & Co slipped 1.8 percent to $32.62 in premarket after the first major U.S. bank to announce results for the period reported lower third-quarter net income as the European debt crisis set back corporate dealmaking. For details, see [ID:nN1E7951DK]

China's trade surplus narrowed for a second straight month in September, as both imports and exports were lower than expected, reflecting global economic weakness and domestic cooling. [ID:nL3E7LD0GV]

"This is a news driven market, it is probably overly sensitive to China data. JP Morgan is a good indicator of what is happening in the banking industry and a little bit of an insight into where consumer banking is headed -- on the conference call we are going to find out how much exposure they have to Europe and that is a concern for a lot of the banking sector," said Kim Forrest, senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.

"That is kind of the news that would want you to make some money off the table"

The S&P 500 is up about 12 percent from its intraday low hit last week on Tuesday and had its largest seven-day rally since March 2009.

S&P 500 futures fell 6 points and were below 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 shed 35 points, and Nasdaq 100 futures lost 6.5 points.
