AI Chip Stocks Lead Nasdaq to New Highs: Can Big Tech Earnings Sustain the Rally?

Driven by the ongoing wave of artificial intelligence, the U.S. stock market has reached another historic moment. AI chip stocks, led by Nvidia (NVDA), have shown strong performance recently, propelling the Nasdaq Composite Index to repeated record highs. As Wall Street turns its attention to the upcoming earnings season for tech giants, market expectations for companies like Apple (AAPL) and Tesla (TSLA) are generally optimistic, but the potential risks amid high valuations cannot be ignored.

AI Chip Stocks Lead the Way: Nvidia's 'Compute Engine' Effect

As a core supplier of AI computing infrastructure, Nvidia's stock price has more than doubled in 2024, becoming a key barometer of market sentiment. According to multiple financial media reports, Nvidia's recently launched new-generation AI chip architecture has further solidified its leading position in the data center market, briefly pushing its market cap above $3 trillion. Meanwhile, competitors like AMD (AMD) and Intel (INTC) are accelerating their AI chip efforts, but Nvidia, with its CUDA ecosystem and first-mover advantage, still commands over 80% of the AI training chip market share.

This 'computing arms race' has not only boosted the overall chip sector but has also rippled through supply chains into areas like semiconductor equipment and memory chips. For example, TSMC (TSM), Nvidia's primary foundry, has seen its advanced process capacity fully utilized, with its stock price also hitting record highs. Market analysts point out that the rally in AI chip stocks has shifted from 'concept speculation' to 'earnings delivery,' providing solid fundamental support for the Nasdaq's rise.

Nasdaq Hits New Highs: Tech Stocks Show Significant 'Suction Effect'

The Nasdaq Composite Index has set multiple record highs in 2024, with a year-to-date gain of over 30% as of recent data. This performance is largely due to the 'suction effect' of large-cap tech stocks—capital continues to flow into AI-related fields, while traditional sectors face relative pressure. According to market research data, the top ten components of the Nasdaq 100 now account for nearly 60% of the index's weight, with AI beneficiaries like Apple, Microsoft (MSFT), Nvidia, and Google (GOOGL) contributing the bulk of the index's gains.

It's worth noting that the Nasdaq's rise is not broad-based. The Federal Reserve's repeated maintenance of high interest rates in 2024 has increased financing costs for small- and mid-cap tech stocks, while large tech companies, with ample cash flow and bargaining power, have instead gained an edge in AI investments. This divergence means the Nasdaq's rally is more of a 'structural bull market' than a full-blown boom.

Earnings Season Preview: Can Big Tech Deliver on High Expectations?

As the third-quarter earnings season approaches, Wall Street's expectations for tech giants like Apple and Tesla are at historic highs. Analysts generally predict that Apple's upcoming iPhone 16 series will integrate AI features for the first time, potentially boosting its services revenue; Tesla plans to launch a robotaxi service in 2025, which will continue to expand its AI training compute needs. Additionally, Microsoft and Google's cloud revenue are seen as key indicators of AI commercialization progress.

However, high expectations also mean high risk. If earnings data fall short, it could trigger sharp stock price corrections. For instance, Tesla saw a single-day drop of over 10% after its Q2 2024 earnings due to declining profit margins. Data from research firm FactSet shows that the average price-to-earnings ratio of Nasdaq 100 components is near 35x, at the high end of the past decade. This suggests that even with good earnings, valuation pressures could limit further upside.

Risks Amid High Valuations: Bubble or New Beginning?

Whether current valuations of AI chip stocks are reasonable has become a focal point of investor debate. Supporters argue that AI technology is at an 'iPhone moment,' where productivity gains will drive sustained earnings growth, justifying high valuations. Opponents point out that historically, tech bubbles burst when valuations become extremely disconnected from fundamentals, such as the 2000 dot-com bubble. Currently, Nvidia's forward P/E ratio exceeds 50x, well above its historical average, while some AI startups lack earnings support for their valuations.

Geopolitical risks also cannot be ignored. U.S. chip export controls on China could tighten further, impacting overseas revenues of companies like Nvidia. According to the Semiconductor Industry Association, China's market accounts for about one-third of global chip sales, and any policy changes could shock the industry.

Conclusion: Cautious Optimism

Overall, the rally in AI chip stocks and the Nasdaq's new highs reflect market optimism about a technological revolution. The upcoming earnings season for big tech will be a key test of this logic. While focusing on earnings growth, investors should also be wary of uncertainties from high valuations, interest rate policies, and geopolitics. As a Wall Street adage goes, 'Trees don't grow to the sky.' In chasing the AI frenzy, staying rational and diversifying risk may be the wiser choice.
