Wednesday’s S&P 500 index futures session saw a pullback amid ongoing earnings season, with bears driving a choppy decline before dip-buyers mitigated some losses.

Overnight, bulls hit resistance at Tuesday’s high, forming a double-top with a high of 6788.75. Bears took control at the opening bell, triggering a choppy sell-off that pushed futures deeper into the red. Over the lunch hour, reports of potential US curbs on China-bound exports made with US software seemed to spark a brief 30+ handle drop. Buyers quickly stepped in to pick up the dip, but the decline resumed. The selloff finally bottomed at 6690.75 where support held. 

In the final two hours, dip-buyers pared losses, lifting the index futures up from the lows. The session closed near the day’s midpoint at 6737, down 36.25 handles.

Thursday brings another wave of earnings reports in the morning and evening.

Among top index components, Walmart Inc (NYSE: WMT) led as the biggest gainer, rising $0.92 or 0.87% to close at $107.14.

That outperformed the cash index’s 0.52% decline by over one percent.

On the other hand, Amazon.com Inc (NASDAQ: AMZN) was the biggest loser, falling $4.08 or 1.84% to close at $217.95.
