How the Magnificent 7 and AI Impact Your Portfolio
How the Magnificent 7 and AI Impact Your Portfolio
Preferred Resource Group | Sept 15, 2025
There's been a lot of talk in recent years about technology, artificial intelligence, and its impact on portfolios. This has only increased with the rising popularity of the so-called “Magnificent 7” and the growing adoption of AI in our everyday lives.
We'd like to share our perspective on this matter and how it impacts your financial planning. This is a big topic, so we'll cover this from the most important angles, including an update on the “Magnificent 7,” the economic impact of AI, and our approach to maintaining a balanced, long-term investment portfolio.
The key is finding the right balance between participating in technological growth while managing the risks that come with market concentration. We hope this helps deepen your understanding on the way we approach fast-growing industries, without taking unwanted risk.
The Role of Technology Companies in a Portfolio
The Magnificent 7 refers to seven large-cap technology-related companies that have driven significant market performance and captured investor attention in recent years: Alphabet, Apple, Amazon, Meta, Microsoft, Nvidia, and Tesla. These stocks have significantly outpaced broader market indices, as the accompanying chart shows. You may have also heard the term “hyperscalers” which refers to companies that are rapidly investing in AI infrastructure.
The technology sector now represents a substantial portion of the U.S. stock market, at about 35% of the S&P 500 index.1 This means that many investors hold more of these companies in their portfolios than they may realize.
The Acceleration of AI in Markets and the Economy
Artificial intelligence has moved beyond the hype stage and is now affecting the broader economy as companies adopt these technologies. The amount invested in AI infrastructure is now in the hundreds of billions, driven by the largest companies.
What makes these numbers meaningful is the transformation occurring across the technology sector. Companies like Microsoft, which recently became the second company to reach a $4 trillion market value alongside NVIDIA, aren't just benefiting from investor enthusiasm – they're creating broad access to AI capabilities.
Several Magnificent 7 companies have delivered strong earnings that exceeded expectations, driving the overall market higher. While these results are encouraging, they also raise important questions about sustainability and current valuation levels that we should carefully monitor. In fact, it was just a few months ago that investors were skeptical about the returns on these AI investments.
Managing Concentration Risk While Capturing Growth
While the performance of technology giants has been impressive, it also highlights what is known as “concentration risk” - a situation where a relatively small number of companies affect portfolio returns.
Concentration risk is the opposite of diversification, and should be taken seriously. On one hand, technology companies have demonstrated exceptional ability to generate growth. On the other hand, having a large portion of market returns dependent on a small group of companies can create volatility. Even the best companies experience challenging periods.
For long-term investors, this environment reinforces the importance of regular portfolio reviews. While it may be tempting to increase exposure to recent winners, a cornerstone of prudent investing is maintaining balance across sectors, company sizes, and geographic regions.
we're here to help you navigate these opportunities and ensure your investment strategy remains aligned with your long-term financial goals. Please don't hesitate to reach out if you'd like to discuss how these developments might affect your specific situation.
