US stock futures wavered as investors watched for updates on negotiations between the US and Iran.

Futures attached to the Dow Jones Industrial Average (YM=F), the benchmark S&P 500 (ES=F), and the tech-heavy Nasdaq 100 (NQ=F) slipped roughly 0.1%.

In day trading on Tuesday, the S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) both rose to record highs. Optimism that the US and Iran could reach a lasting peace agreement somewhat soon, as well as confidence in the chip trade, lifted markets.

A conclusive end to the US-Iran war, however, remains murky, with Secretary of State Marco Rubio cautioning that any deal would likely take a few days to formalize. In the meantime, the Strait of Hormuz remains mostly shut to commercial traffic.

Earnings season continues to wrap up this week, with Marvell Technology (MRVL), Salesforce (CRM), Snowflake (SNOW), and Abercrombie & Fitch (ANF) set to report their results Wednesday.
