#分享美股交易赢英伟达股票 In 2026, U.S. AI stocks underperformed expectations and rose too quickly, with NVIDIA and TSMC showing the strongest certainty.

This article compiles the stock price increases, annual revenue growth expectations, and valuation data of core U.S. AI companies from January 2 to June 5, 2026, analyzing sector differentiation logic from fundamental and valuation perspectives. In an environment of overall market volatility and cautious investment sentiment, NVIDIA and TSMC, with solid fundamentals and low valuation levels, have become the most certain targets within the sector.

1. Sector Data Breakdown
(1) Four companies with the lowest interval gains: low growth, strong fundamentals, valuation with a safety margin
During the statistical period, NVIDIA, Broadcom, Google, and TSMC had the lowest stock price increases: NVIDIA up 10.13% (revenue growth 60%), Broadcom 11.66% (revenue growth 46%), Google 11.82% (revenue growth 14%), TSMC 37.04% (revenue growth 32%).
From the valuation distribution pattern, the lower the position, the lower the valuation level. Among them, NVIDIA boasts the top revenue growth in the entire sector but has a relatively low forward valuation; TSMC maintains high revenue prosperity, and its valuation also falls into the sector’s undervalued zone. Both are global leaders in AI chips and AI wafer foundry, respectively, with significant advantages in high growth and low valuation combinations.
(2) Targets with significantly overextended performance expectations: high valuation requires performance validation
Many listed companies’ stock price increases significantly outpace their revenue growth, relying on market optimistic expectations. Long-term performance realization is needed to digest high valuations. Once the market enters a correction phase, overly high expectations may become a downward trigger. These can be divided into three categories:
1. Semiconductor equipment companies: ASML, Lam Research, Applied Materials, KLA, etc., with annual revenue growth of only 10%–22%, but their stock prices generally increased by 54%–77%, far exceeding fundamental growth.
2. CPU sector stocks: Intel, ARM, AMD saw explosive stock price increases, several times their expected revenue growth, with current valuations at high levels. The market has assigned excessive premiums to their growth potential, and sustained earnings surprises are needed to validate growth logic.
3. Marvell: Driven by market sentiment such as endorsement from industry giants and the trillion-dollar market cap fantasy, stock prices surged sharply, showing emotional trading characteristics. High valuation also requires subsequent operational data to support.
2. Summary
NVIDIA and TSMC: As leaders in AI chips and wafer manufacturing, respectively, their growth certainty is maximized, and their valuations are at the sector’s low end. They are preferred assets for both defensive and growth-oriented strategies during panic markets.
Most high-gain targets face valuation digestion pressure: equipment, CPU chips, Marvell, and other stocks have surged based on market optimism, already overextending future performance expectations. When macro and industry uncertainties increase, high expectations can amplify stock volatility, requiring a long cycle of actual revenue realization to deflate bubbles. $NVDA $TSM ‌ ‌
