Monday’s S&P 500 index futures session saw a split second of red but still ended in the green, with sellers curbing weekend gains amid late geopolitical jitters.

Overnight, traders bid futures up steadily, hitting a high of 6736 by early morning. Premarket attempts to breach this level fizzled as sellers took charge. A small sell-off kicked in just before the regular session, leading to choppy action post-open. The first hour saw bulls and bears locked in a stalemate, but bears gained traction before lunch, pushing a choppy decline. Bulls eventually found footing near the psychological 6700 level, stabilizing the slide.

Late in the session, reports of Israel’s prime minister taking a “critical step” toward ending the Gaza war seemed to spook market participants, driving futures to a fresh low of 6696.25. Buy-the-dippers rallied in the final hour, lifting the index back from unchanged. The session closed below the day’s midpoint at 6713.50, up 17 handles.

Tuesday, the last day of the month and quarter, brings more fedspeak in the morning and afternoon, alongside minor macro data.

Among top index components, NVIDIA Corp (NASDAQ: NVDA) led as the biggest gainer, rising $3.69 or 2.07% to close at $181.88

That outperformed the cash index’s 0.28% gain by a magnificent seven times. 

Broadcom Inc (NASDAQ: AVGO) was the biggest loser, falling $6.63 or 1.98% to close at $327.90.
