Major U.S. indices — the S&P 500, Nasdaq, and Dow — all closed at record highs in a session where technology strength overwhelmed geopolitical noise from US-Iran tensions. The rally was anchored by names with genuine fundamental momentum: Microsoft posted $281.7B in FY2025 revenue (+14.9% YoY) with best-in-class 68.8% gross margins and $13.64 diluted EPS, while Marvell Technology delivered a sharper 42.1% revenue surge to $8.2B with 51% gross margins, reflecting booming AI-chip demand. Uber rounded out the focus list with $52B in revenue (+18.3% YoY) and a 19.4% net margin, a meaningful profitability milestone for a platform once defined by losses.

The geopolitical backdrop — US-Iran war uncertainty — has historically been an oil-price and risk-sentiment shock, yet equity markets absorbed it with apparent ease. This divergence is notable: either markets are pricing a contained, low-probability conflict escalation, or the tech earnings wave is providing enough fundamental cover to suppress volatility. MRVL's 42% growth rate is the most extreme of the group and likely the sharpest catalyst driver, given its direct AI-infrastructure exposure.

The tension in this setup is straightforward: record highs on geopolitical uncertainty is a classic late-rally condition. Bulls point to accelerating fundamentals — MRVL's AI-chip tailwinds, MSFT's Azure cloud compound growth, and UBER's first full year of real profitability. Bears note that record-high indices with war risk in the background create asymmetric downside if the geopolitical situation deteriorates or if any of these earnings prints disappoint relative to elevated expectations.

What to watch: any escalation in US-Iran tensions that spikes oil above $90-$95/bbl would likely reprice risk across the board regardless of tech fundamentals. On the bull side, continued AI capex commitments from hyperscalers (which feed MRVL directly) and MSFT's Azure growth rate in the next print would be the confirming signals.
