The broad index inched up 0.1% to 4,405.80. The Nasdaq Composite added 0.1% to 14,541.79. The Dow Jones Industrial Average shed 66.57 points, or nearly 0.2%, to 34,894.12.
The S&P 500 snapped a two-day losing streak while the Dow logged its third-straight losing session. Meeting minutes released Wednesday from the Fed's gathering in July showed the central bank has started eyeing tapering its $120 billion in monthly bond purchases before the year-end.
For the week, the three major indexes are in the red.
