Nvidia Achieves $5 Trillion Market Cap Amid AI Surge

Nvidia made history on March 13, 2024, by surpassing a market capitalization of $5 trillion during intraday trading, marking a significant milestone for publicly traded companies. This achievement is fueled by an unprecedented investor enthusiasm for artificial intelligence (AI) technologies. Over the past three years, tech stocks have doubled the returns of the broader market, reflecting a growing appetite for companies at the forefront of AI advancements.

The semiconductor giant, known for its critical role in AI processes, has seen its stock price soar following various strategic partnerships with influential firms such as OpenAI, Intel, and Oracle. The recent GPU Technology Conference provided fresh insights into Nvidia’s robust revenue prospects, further energizing investor confidence. According to Brian Colello, a senior equity analyst at Morningstar, “AI demand doesn’t appear to be slowing at all,” suggesting that the expansion of the AI supply chain is accelerating.

Market Dynamics and Risks

On March 12, Nvidia’s stock gained an impressive 5%, boosting its market cap by approximately $250 billion. This increase alone surpassed the total market capitalization of all but 31 publicly traded companies in the United States. The surge in Nvidia’s stock is part of a broader trend, as other tech giants like Microsoft and Apple also reached significant milestones, with both surpassing a $4 trillion market cap on the same day Nvidia achieved its record.

Despite this exhilarating growth, concerns are emerging regarding potential overvaluation in the tech sector. The Morningstar US Technology Index has dramatically outperformed the broader market, rising 167% since the beginning of the bull market three years ago. This contrasts sharply with the Morningstar US Market Index, which has only doubled its gains during the same period.

Investors are now paying a premium for leading tech stocks, which raises questions about sustainability. After a market selloff earlier this spring, tech stocks rebounded strongly, and the sector is currently trading at a premium of 5%. Dave Sekera, chief US market strategist at Morningstar, noted that many AI mega-cap stocks are trading near or above their fair value estimates, leaving little room for error should AI growth slow.

Concentration and Outlook

The rapid ascension of tech stocks has led to an increased concentration in major market indexes. In the Morningstar US Large-Mid Index, the top five companies, all heavily involved in AI, account for over a quarter of the index’s total weight. This concentration can significantly influence the index’s returns; for instance, Nvidia contributed 1.2 percentage points to the index’s 8.1% return in the third quarter of 2023, while Apple added 1.4 points to the total.

While the current momentum presents opportunities for investors, it also poses risks. Dominic Pappalardo, chief multi-asset strategist for Morningstar Wealth, highlighted that if the market dynamics shift and tech stocks begin to lag, investors may experience a disproportionate downturn.

As the tech sector continues to evolve, the interplay between innovation, market sentiment, and valuation will be critical in determining the sustainability of these remarkable gains. Investors are advised to remain vigilant, balancing enthusiasm for AI advancements with caution over potential market corrections.
