S&P 500 index futures dip 0.25 percent

SAN FRANCISCO, Feb 7 (Reuters) - S&P 500 stock index e-mini futures dipped 0.25 percent late on Wednesday after the regular trading session, suggesting U.S. stocks might lose ground at the beginning of the next trading session.

Earlier on Wednesday, the S&P 500 index ended down 0.50 percent, with Wall Street spooked about a recent retreat in stock prices as U.S. Treasury bond yields resumed their rise. (Reporting by Noel Randewich)
