Wednesday’s S&P 500 index futures session extended the losing streak to four days, grinding to fresh monthly lows in persistent pre-holiday selling pressure.

Overnight, bulls attempted to lift from Tuesday’s dip, reaching an early high of 6882.50 before resistance pinned gains just below that level. As the open neared, bears and profit-takers emerged. The regular session saw bids erode steadily. After a brief pause near unchanged, selling accelerated post-first hour, pressing toward the psychological 6800 level where the decline temporarily slowed into chop.

Bears pushed on in the afternoon, edging slightly lower and culminating in late selling that marked the session low of 6775.50 just before the bell. The regular session closed near that low at 6778.50, down a hefty 77.75 handles.

Among top index components, Berkshire Hathaway Inc (NYSE: BRK.B) flipped its role from Tuesday and emerged as the biggest gainer. The holding company rose $4.49 or 0.90% to close at $504.27.

That performance was only two percent better than the cash index’s 1.10% decline.

Also flipping its role, the biggest loser was Tesla Inc (NASDAQ: TSLA). For the day, the AI/EV company plunged $22.62 or 4.62% to close at $467.26 as investors capitalized on its recent rally.
