U.S. stock index futures were little changed on Thursday as higher oil prices and the prospect of an escalating Middle East war offset support from strong corporate results. The latest military strikes between the U.S. and Iran have added uncertainty to markets, although Invesco’s Benjamin Jones said investors had absorbed significant disruption better than expected. Brent crude was up 0.23% after trading lower earlier, while Goldman Sachs analysts said market adaptability to the conflict could limit oil’s upside even during prolonged regional disruptions. Treasury yields eased as a bond-market selloff slowed, reducing one recent pressure on equities. Broadcom fell 2.29% in premarket trading after its fourth-quarter revenue forecast missed Wall Street expectations, while Snowflake surged 23.76% after issuing a strong annual revenue forecast. Investors were expected to scrutinize Friday’s nonfarm payrolls report for indications about the Federal Reserve’s interest-rate outlook.
