Thursday’s S&P 500 index futures session turned a weak overnight selloff into a convincing bullish reversal, with dip-buyers absorbing early pressure and powering a steady climb into the close and beyond.

Overnight, bears dominated, selling the post-Fed rally and Oracle Corp’s disappointing earnings, driving the index futures to a low of 6817.50 (double-bottom with last Wednesday) during European market hours. Dip-buyers gradually emerged, though the index stayed red into the regular-session open. Sellers tried one more push lower, but bulls firmly defended near yesterday’s low and quickly flipped momentum.

Morning chop gave way to a smooth afternoon uptrend after resistance cracked over lunch. Minor profit-taking hit into the bell, but buyers held the psychological 6900 level. The regular session closed near the intraday high at 6907.25, up 15.50 handles. After hours, Broadcom, Inc.’s (NASDAQ: AVGO) strong quarterly report helped send the index futures soaring to a high of 6928.75.

Friday offers a quiet day with no notable earnings on the calendar and some fedspeak throughout the day.

Among top index components, Walmart Inc (NYSE: WMT) emerged as the biggest gainer. The retail giant rose $2.34 or 2.07% to close at $115.52, carving out a fresh all-time closing high.

That performance was a neat nine times better than the cash index’s 0.23% advance.

On the other hand, the biggest loser was Alphabet Inc (NASDAQ: GOOGL). For the day, the tech giant fell $7.78 or 2.43% to close at $312.43.
