US Tech Stocks: Thematic Trend or a Bubble?

18th October 2024
The Magnificent 7 - Nvidia, Apple, Tesla, and others - remain major players in the S&P 500, collectively representing over 33% of its market capitalisation. As of October 2024, Nvidia's stock has skyrocketed, thanks to its dominance in AI chips, while other tech leaders have delivered mixed results. For example, despite Nvidia’s overperformance, not all tech giants have shared in the same success, and some have shown signs of slowing momentum.
As investors, we must ask whether this concentrated success signals a long-term trend or is indicative of a bubble. History offers us lessons, particularly the dot-com bubble of the early 2000s. Back then, speculation drove tech stocks sky-high before a collapse wiped out nearly 80% of the Nasdaq's value. While today’s tech companies are highly profitable with real-world applications, their valuations—especially with price-to-earnings ratios as high as Nvidia's—raise questions about whether they can sustain this growth without correction​.
Brigantia's Perspective on Diversification and Risk

At Brigantia, we recognise the importance of understanding these market shifts, but we firmly believe that a well-diversified portfolio and regular rebalancing are critical. When one sector, like tech, dominates returns, rebalancing allows us to capture some gains and redistribute them across other assets, reducing risk if a correction comes. This isn’t about jumping between investments based on the latest headlines; it’s about having a long-term, disciplined plan.

Comparing Bubbles: Then vs. Now

The difference between the 2000s dot-com bubble and today’s tech boom is the maturity of the companies involved. Many of the Magnificent 7 are established, highly profitable companies with cash flows and real revenue. However, that doesn’t eliminate the potential for a correction, especially when valuations seem stretched.

Conclusion

Ultimately, we believe that long-term financial success comes from thoughtful planning and avoiding the short-term noise. While the tech sector might continue to perform well, having the discipline to rebalance portfolios and stay focused on long-term goals ensures smoother results, no matter the market's ups and downs. At Brigantia, this is where we can truly add value - guiding investors through volatile markets, maintaining focus on the long-term picture, and helping to realise consistent returns over time.
