Index futures down as trading resumes

NEW YORK (Reuters) - U.S. stock index futures were down slightly late Wednesday after they resumed trading for the overnight session.

S&P 500 e-mini futures and Nasdaq futures were both down 0.1 percent.

During the regular session, the S&P 500 marked its biggest daily percentage fall since Feb. 8 - 3.3 percent - and Nasdaq registered its biggest fall since June 24, 2016 - 4.1 percent - as rising U.S. Treasury yields sent investors fleeing from risky assets.
