Market Overview: Nvidia and Semiconductors Extend AI Leadership
The S&P 500 finished nearly flat for the week, up just 0.00049%, but the market narrative was anything but quiet. Once again, semiconductors took center stage as Nvidia extended its rally and AI infrastructure names broadly climbed. In contrast, software, telecom, and green tech posted steep losses. Investors continued rotating into earnings-backed themes, with memory and compute outperforming, while traditional defensives and speculative plays saw fresh selling.
The divergence within tech sharpened. While Nvidia and AMD soared, companies like Oracle and Alphabet faced profit-taking. Inflation expectations, ongoing rate debates, and positioning ahead of PMI data drove caution. The result: a market that is still bullish on AI but quick to punish valuation excess.
On the downside, healthcare dropped 2.19%—the worst-performing sector of the week—amid rising political scrutiny of drug prices and weak biotech sentiment. Utilities and telecoms also fell, likely reflecting investor de-risking in response to upcoming policy uncertainty. This divergence suggests the market is preparing for binary outcomes heading into Q2 earnings season, with a pronounced tilt toward capital spending and AI-related upside in tech versus margin compression risks elsewhere.
Sector Performance – 7-Day Returns
According to Chart 1, the strongest sectors this week were Technology (+0.92%), Tech Hardware (+2.41%), and Electronic Equipment (+2.15%). Semiconductors were again one of the top contributors, rising 1.60%. In contrast, Software dropped 0.29%, and Communications fell 0.25%. Despite the broader tech sector posting gains, performance was driven almost entirely by semiconductors and hardware, while services and software lagged.
