Nvidia Earnings Eve: Can the US Tech Sector Sustain Its Rally? A Nasdaq and S&P 500 Analysis

Nvidia Earnings Eve: Can the US Stock Tech Sector Sustain Its Rally?

As global investors focus on the upcoming Nvidia earnings report, the US tech sector once again serves as a barometer of market sentiment. As the undisputed leader in AI chips, Nvidia's performance not only directly affects its own stock price but is also seen as a key gauge for the health of the entire AI supply chain and the valuation of the Nasdaq and S&P 500 tech sectors. On the eve of the earnings release, the market is searching for clues from capital flows, technical indicators, and macroeconomic expectations to determine whether tech stocks can continue their recent rally.

Nvidia Earnings: A 'Stress Test' for the AI Boom

Nvidia's upcoming quarterly earnings are widely regarded by Wall Street analysts as a 'stress test' for the current AI investment boom. Over the past few quarters, the company has consistently delivered earnings beats, driven by explosive growth in its data center business, lifting chip stocks like AMD and Broadcom, as well as cloud giants like Microsoft and Google, to new highs. However, with growing skepticism about the pace of AI commercialization and valuation pressures, this report's revenue guidance and gross margin changes will be key variables. According to a consensus from FactSet, analysts generally expect Nvidia's revenue to maintain triple-digit year-over-year growth, but sequential growth may slow. If the report confirms sustained strong demand for AI computing power, the tech sector could gain new upward momentum. Conversely, if guidance disappoints, it could trigger short-term profit-taking and weigh on the Nasdaq index.

Nasdaq and S&P 500: The 'Resonance Effect' of Tech Heavyweights

Currently, tech stocks account for over 50% of the Nasdaq Composite Index and nearly 30% of the S&P 500. As one of the largest stocks by market cap, Nvidia's price movements have a significant leverage effect on both indices. Recently, the Nasdaq has strengthened on the back of tech stocks, but market breadth has narrowed—meaning the gains of a few leading stocks mask the weakness of the majority. This 'narrow rally' makes Nvidia's earnings a core variable determining the short-term direction of the indices. A positive report could drive capital back from defensive sectors (like utilities and healthcare) into tech growth stocks, pushing the Nasdaq to challenge historical highs. A disappointing report could trigger a broad tech sector pullback and drag the S&P 500 below key support levels. Notably, the Federal Reserve's monetary policy expectations are also influencing capital flows. Although the market generally expects a delayed rate cut cycle, if Nvidia's earnings show that corporate AI capital expenditure is unaffected by interest rates, tech stocks could still outperform the broader market.

Capital Flows: Divergence Between Institutional Rotation and Retail Sentiment

Capital flow data reveals a clear divergence between institutional and retail investors on the eve of the earnings. According to EPFR Global, US tech stock funds have seen net inflows for three consecutive weeks, but the pace has slowed, suggesting some institutions are adopting a wait-and-see approach or trimming positions to lock in profits. Meanwhile, call option volumes on retail trading platforms have surged, particularly for short-term out-of-the-money call options on Nvidia, reflecting retail investors' strong bets on an earnings beat. This divergence means that if the actual results deviate from retail expectations, it could trigger significant volatility in the options market, amplifying intraday price swings. Additionally, hedge funds' net long positions in the tech sector have risen to a one-year high, raising the risk of programmatic selling if earnings disappoint.

Technicals and Macro Backdrop: Opportunities and Risks Amid High-Level Consolidation

From a technical analysis perspective, Nvidia's stock is trading near historical highs ahead of earnings, with the Relative Strength Index (RSI) indicating overbought conditions, suggesting short-term pullback risks. However, the price-to-earnings ratio of the S&P 500 tech sector remains below its 2021 peak, leading some analysts to argue that current valuations are supported if AI profit expectations materialize. On the macro front, the US 10-year Treasury yield has recently fluctuated around 4.2%, without a significant uptick, providing a relatively favorable interest rate environment for tech stocks. However, geopolitical risks (such as changes in chip export controls) and policy uncertainties in the US election year remain potential factors dampening risk appetite for the tech sector. In summary, Nvidia's earnings are not just a test of the company's fundamentals but also a collective vote on the sustainability of the AI narrative.
