The advance was led by a chip-driven surge, with Micron Technology (NASDAQ: MU) jumping over 19 percent and topping a $1 trillion Market Capitalisation after an aggressive UBS upgrade, while other AI-linked semiconductor stocks including Advanced Micro Devices (NASDAQ: AMD) and Qualcomm (NASDAQ: QCOM) also rose alongside mega-caps including Alphabet (NASDAQ: GOOGL).

What Drove the Rally

The session was defined by semiconductor strength anchored in AI infrastructure optimism. Leading the advance, Micron Technology jumped over 19% and topped a $1 trillion valuation during the day after an aggressive UBS upgrade. The move reinforced the narrative that AI-driven Demand for memory and advanced chips remains intact and is accelerating. NDX's 1.76 percent gain outpaced the broader COMP by 57 basis points, confirming that megacap technology names led the session. The NQUS500LC's 0.61 percent gain, while more modest, confirmed that buying interest extended beyond the largest technology names into the wider US large-cap universe.

What to Watch Next

The week's primary event is Salesforce (NYSE: CRM) reporting its fiscal Q1 FY2027 results after market close on May 27. Wall Street expects non-GAAP EPS of approximately $3.13 and Revenue of approximately $11.06 billion. Agentforce annual Recurring Revenue, which stood at $800 million as of Q4 FY2026 up 169 percent year over year, is the number investors are focused on. Options traders are pricing in an 8.7 percent post-earnings move in either direction. Federal Reserve speakers Logan, Cook and Jefferson are also scheduled during the week, with any commentary on rate expectations likely to influence growth stock valuations. The RIKU and BWGC IPOs price on May 27, adding two small-cap debuts to an already catalyst-heavy session.

Final Takeaway

The Nasdaq Composite's 1.19 percent gain and NDX's historic cross of 30,000 mark a constructive opening to a week packed with catalysts. Whether the advance extends depends primarily on Salesforce's Agentforce revenue numbers tonight and the tone from Fed speakers, with the broader chip rally providing momentum heading in.
