U.S. stocks closed modestly higher on Monday as investors weighed signs of a potential diplomatic breakthrough in the Iran conflict against lingering uncertainty over the scope and duration of hostilities. Reports that U.S. allies were pressing for a last-minute ceasefire agreement offered a measure of relief, though retaliatory rhetoric from Tehran and President Trump’s threat of intensified strikes kept a floor under volatility. The result was a cautiously positive session, with buyers favoring technology, defense, and infrastructure names.
Index Closing Levels
The Dow Jones Industrial Average rose 165.21 points, or 0.36%, to close at 46,669.88. The S&P 500 added 29.14 points, or 0.44%, finishing at 6,611.83. The Nasdaq Composite led the way with a gain of 117.16 points, or 0.54%, ending the session at 21,996.34. All three benchmarks built on last week’s jobs report, which showed the economy added 178,000 positions in March — well above the roughly 50,000 that forecasters had expected — easing some of the recession anxiety that had crept into recent trading sessions.
Notable Movers
Kratos Defense & Security Solutions (KTOS) surged roughly 10% after Jefferies upgraded the stock to Buy, citing the company’s dominant position in hypersonic testing and a projected 31% compound annual growth rate through 2028. The analyst note highlighted a $14 billion opportunity pipeline and expectations that Kratos’ hypersonic segment could double its revenue this year alone.
Boot Barn (BOOT) also rallied over 10% on the session, extending a streak of strong performance in specialty retail. Lumentum (LITE) climbed 6.6% to a fresh all-time high, benefiting from continued capital flows into AI and data-center infrastructure. Seagate Technology (STX) rose 5.5% and likewise reached a 52-week high, as investors rotated into companies supplying the storage backbone for artificial intelligence workloads.
On the losing side, Tesla (TSLA) slipped about 2%, still nursing wounds from last week’s disappointing first-quarter delivery report. The electric-vehicle maker shipped 358,023 vehicles in Q1, missing the 365,645 consensus estimate, while production exceeded deliveries by over 50,000 units — a gap that raised fresh concerns about softening demand. The stock is now down roughly 20% on the year.
In the crypto-adjacent space, MicroStrategy (MSTR) jumped 6.6% as Bitcoin approached $70,000 on the back of institutional buying, including MicroStrategy’s own $330 million purchase announced over the weekend.
Looking Ahead
Investors face a data-heavy week that could set the tone for the rest of April. Delta Air Lines (DAL) and Constellation Brands (STZ) report earnings on Wednesday, offering a read on consumer travel and spending. Thursday brings the fourth-quarter GDP revision and February PCE price data — the Federal Reserve’s preferred inflation gauge. The week culminates Friday with the March consumer price index, which will be closely watched for signs that the recent jobs strength is feeding through into prices. With geopolitics still fluid and inflation data on deck, traders will likely keep one eye on headlines and the other on the economic calendar.
