Evening Market Recap - Monday, 18-May

Why It Matters

Markets are vulnerable to headline-driven swings from Middle East tensions and to a near-term unwind in AI/MAG-7 positioning, while incoming Fed commentary, FOMC minutes and heavy earnings could amplify volatility and reprice risk across sectors and yields.

Summary

U.S. markets traded mixed on May 18 as breadth was positive but leadership rotated away from semiconductors and big tech, leaving the Dow modestly higher while the S&P 500 and Nasdaq closed lower. Memory names, Tesla and Nvidia weighed on sentiment, while software, energy, banks and consumer staples outperformed; small caps lagged. Treasuries were a touch firmer at the short end, the dollar softened and WTI crude jumped about 3.3% amid renewed U.S.-Iran headline volatility. Corporate headlines included NextEra’s ~$66.8 billion all-stock bid for Dominion, LiveRamp’s agreed takeover, a steep sell-off in Regeneron after clinical misses, and a busy earnings and Fed-speaker calendar ahead — including Nvidia after the close on Wednesday.

Original Description

Major US equity indexes were lower in Monday trading, though stocks ended well off worst levels. The US-Iran war narrative continues to offer a lot of headline volatility, with little progress toward a resolution. In macro news, the May NAHB housing market index beat, rebounding after falling to its lowest level since last September in April.
