Thursday’s S&P 500 index futures session brought another round of volatility, with early strength fading as sellers gradually gained control through the afternoon.

Overnight trading was mixed, with futures pushing to a high of 6,900.75 before reversing lower and sliding toward a session low of 6,777.00 ahead of the U.S. open. The regular session opened near 6,883 and initially held steady, but buying momentum quickly faded as sellers pressed the market lower through the morning.

Midday trading remained choppy, with brief stabilization attempts unable to build momentum. A selloff developed late morning, sending futures toward the lower end of the range before dip-buyers stepped in during the afternoon to recover part of the decline.

By the close, S&P 500 index futures settled at 6,835.25, down 40.75 handles or -0.59%, finishing below the day’s midpoint.

Among top index components, Broadcom Inc (NASDAQ: AVGO) led as the biggest gainer, rising 4.79% during the session.

The biggest loser ended up being Walmart Inc. (NYSE: WMT), which declined 3.52% amid broader weakness in consumer-focused stocks.
