U.S. stock index futures held small gains Thursday following a batch of economic reports, but worries over the ongoing "fiscal cliff" negotiations kept investors cautious.
On the economic front, producer prices fell 0.8 percent in November, declining for the second month, according to the Labor Department, as the cost of energy dropped the most in over three years. Economists polled by Reuters had expected a decline of 0.5 percent.
Jobless claims fell for the fourth-straight week, dropping 29,000 to a seasonally adjusted 343,000, according to the Labor Department. Meanwhile, the four-week moving average for new claims fell 27,000 to 381,500.
Additionally, retail sales edged up 0.3 percent in November, according to the Commerce Department, but the gain was less than the increase of 0.5 percent economists had expected, according to a Reuters poll.
