U.S. stock index futures edged lower on Friday, pausing after the previous session's rally set Wall Street's main indexes on track for weekly gains following the Federal Reserve's pivotal stance on monetary policy earlier in the week.

Wall Street saw a mixed open as investors reacted to a recent Fed rate cut and several corporate developments. The S&P 500 hit a record high, while the Dow surpassed 42,000 points. The Fed is expected to cut rates further in November and December amid steady economic growth.
