Wednesday’s action in the S&P 500 index futures stayed true to recent form, with headlines (notably, tariff concerns) steering the ship. This time, sellers took nearly full control during the regular session. 

Overnight, the index futures wobbled around unchanged, peaking at 5836.50. The open saw buyers make a quick run at that overnight high, but resistance stood firm. Sellers swooped in shortly after, breaching the premarket low with ease. Early support flickered at Tuesday’s low in the 5800 area, but once bears punched through, they didn’t glance back. Tech and growth names spearheaded the slide all day, with bulls struggling to muster a bid.

Support finally kicked in at Monday’s low, around the 5740 area. Bulls clawed back some losses last minute, but the session still wrapped up somewhat near the day’s low at 5759.50, shedding 67 handles. Among macro news, more fedspeak is expected Thursday, plus February retail data and US trade balance dropping at 8:30 AM ET.

Among the index’s top components, Berkshire Hathaway Inc Class B (NYSE: BRK.B) stood tall as the biggest gainer. The holding company climbed $4.36, or 0.82%, to close at $533.21, notching new all-time and all-time closing highs. 

That resilience beat the cash index’s 1.19% drop by over two percent.

On the flip side, NVIDIA Corp (NASDAQ: NVDA) took the hardest hit. The chip designer tumbled $6.93, or 5.74%, closing at $113.76, dragged down amid the growth rout.
