(Reuters) -U.S. stock index futures rose on Friday and put Wall Street on track for a higher close for the week, which was dominated by the Federal Reserve's signals on a possible end to rate hikes and mixed earnings reports from marquee tech companies. Chip stocks surged in premarket trading after Intel posted a surprise quarterly profit, while global stock markets eased following Japan's tweaks to its monetary policy. The Dow snapped its longest winning streak since 1987 in the previous session as U.S. Treasury yields pressured stocks lower after news that the Bank of Japan will allow long-term interest rates to rise.
