Futures fluctuate after budget deal; Costco dips

U.S. stock index futures wavered on either side of neutral Wednesday after U.S. lawmakers reached a deal to fund the government past mid-January added to expectations the Federal Reserve will start cutting back its stimulus program.

Late Tuesday in the U.S., Senate Democrats and Republicans reached a deal to reduce automatic spending cuts and the deficit levels by $23 billion over two years.

Analysts told CNBC they believed the deal would be passed with policymakers looking to avert another damaging government shutdown like the one seen in October.

Investors have also been focused over the timing of a reduction in the U.S. Federal Reserve's stimulus program and will be looking ahead to the Federal Open Market Committee's (FOMC) last policy meeting of the year, next Tuesday and Wednesday.
