Nvidia, CrowdStrike Results Spark Fresh Tech Rally

Nvidia and CrowdStrike delivered standout post-earnings moves this week, refocusing market attention on AI infrastructure buildout and cybersecurity budgets. Nvidia shares rose about 6% after another sizable beat, while CrowdStrike jumped roughly 15% on record net new annual recurring revenue (ARR) and a higher full-year outlook. Nvidia said fiscal second-quarter revenue climbed 106% year over year to $96.2 billion, topping Wall Street expectations around $92.2 billion. Adjusted earnings came in at $2.22 per share. Data Center revenue surged 117% to $89 billion. The company also guided fiscal third-quarter revenue to $108 billion, ahead of consensus estimates. The guidance adds weight to the view that the AI infrastructure cycle still has further runway. Nvidia expects revenue growth of about 70% in fiscal 2028 and said demand remains strong enough that supply constraints persist. Nvidia remains the dominant name in AI chip stocks, reinforcing the broader growth narrative tied to the expanding AI ecosystem. Margins are emerging as a key watch item. Higher memory and component costs are expected to weigh on gross margin, and Nvidia's Q3 outlook assumes no Data Center compute revenue from China. Reuters has flagged China restrictions and supply limitations as ongoing uncertainties, even as global AI demand accelerates. The rally also comes after an unusual pullback: Nvidia entered the report with six straight down sessions, its longest losing streak since 2022. CrowdStrike's results offered a separate growth signal for cybersecurity. Revenue increased 26% to $1.47 billion, including 27% growth in subscription revenue to $1.40 billion. Net new ARR hit a record $333 million, up 51% year over year, lifting ending ARR to $5.84 billion. The company raised its fiscal 2027 outlook and now expects net new ARR growth of about 34% at the midpoint. Investors had been closely tracking CRWD following its four-for-one stock split and concerns that its premium valuation leaves little room for missteps. [CHART 2 — PLACE HERE: Nvidia vs. CrowdStrike earnings snapshot. Table with revenue, YoY growth, key growth metric and post-earnings stock move: NVDA $96.2B / +106% / Data Center +117% / ~+6%; CRWD $1.47B / +26% / net new ARR +51% / ~+15%.] Taken together, the moves suggest the market is still willing to pay up for high-growth technology names when results materially exceed expectations. For Nvidia, the central question remains how long extraordinary AI infrastructure spending can persist. For CrowdStrike, attention turns to whether faster ARR growth can support the valuation. For investors looking beyond individual stocks, the rallies also underscore the value of diversification as growth-stock valuations expand.
