U.S. stock index futures slipped slightly Thursday as investors hunkered down ahead of key consumer inflation data that is likely to factor into the outlook for interest rates. 

At 05:50 ET (09:50 GMT), Dow Jones Futures were 45 points, or 0.1%, lower, S&P 500 Futures fell 10 points, or 0.2%, and Nasdaq 100 Futures dropped 39 points, or 0.2%.

The main indices registered a positive session on Wall Street on Wednesday, after the minutes of the Federal Reserve’s September meeting showed a substantial number of policymakers backed its 50 basis point cut. 

But the minutes also showed policymakers not committing to any particular pace of cuts in the future, which kept investors skittish over just how much rates will fall this year. 

The broad-based S&P 500 rose 0.7%, the Dow Jones Industrial Average surged 1% to a new record closing high, and the NASDAQ Composite gained 0.6%.
