AI Momentum Keeps Tech in Focus 27/05/2026

 HOT stories for today

Market wrap:

• Technology shares led Wall Street higher Tuesday, sending the S&P 500 and Nasdaq Composite to fresh intraday and closing records. The S&P 500 rose 0.6%, while the Nasdaq jumped 1.2%. The Dow Jones Industrial Average lagged, falling 118.02 points, or 0.2%. Micron Technology was a standout, surging 19% and briefly pushing its market value above $1 trillion for the first time as investors continued to chase AI-linked semiconductor names. Sentiment was also supported by signs of progress in U.S.-Iran talks.
• President Donald Trump said negotiations were “proceeding nicely,” while U.S. Central Command said early Tuesday strikes in southern Iran were conducted in self-defense and with restraint during the ongoing ceasefire. Bitcoin slipped below $77,000 as U.S.-Iran naval clashes added some caution across risk assets. Earnings remain in focus on Wednesday, with Bank of Montreal, Bath & Body Works, Capri, Dick’s Sporting Goods, Manchester United, and Abercrombie & Fitch due before the open.

Micron Joins the AI Trillion-Dollar Club

• Micron (MU) topped $1 trillion in market value for the first time Tuesday, with shares surging 19% as investors piled into memory-chip stocks tied to the next stage of the AI boom. The rally followed a major UBS upgrade, with the firm tripling its price target to $1,625 from $535. UBS pointed to long-term supply agreements, stronger pricing power and structural changes across the memory-chip market. 
• AI demand has triggered a global memory shortage, allowing Micron and rivals SK Hynix and Samsung to raise prices as customers race to secure chips for agentic AI workloads. The move also shows the AI trade broadening beyond Nvidia, with investors increasingly chasing CPUs, memory and other infrastructure names needed to power large-scale AI systems. Micron shares have now more than tripled this year, while Intel has also surged as investors bet on a wider semiconductor revival.

Stocks on the move:

• Box (BOX): Shares slipped 2% after full-year adjusted earnings guidance came in below expectations, despite a small first-quarter earnings and revenue beat.
• Zscaler (ZS): Shares tumbled 16% after current-quarter revenue guidance missed estimates, even as fiscal third-quarter earnings and revenue topped forecasts.
• Palo Alto Networks (PANW), CrowdStrike (CRWD): Shares fell 2% in sympathy with Zscaler’s weaker outlook.
• Semtech (SMTC): Shares jumped 8% after beating first-quarter estimates and issuing stronger-than-expected current-quarter guidance.
• Insulet (PODD): Shares dropped about 9% after announcing a voluntary correction for certain pod lots due to a manufacturing issue that could affect insulin delivery.
