One of the things I enjoy most about producing videos and educational content is the thoughtful feedback and questions from viewers. Often, the comments themselves highlight areas where investors are seeking a deeper understanding of value investing principles. In this article and accompanying video, I respond to several of those comments while also analyzing a group of stocks that currently dominate the S&P 500 Index.
Today, a relatively small number of mega-cap companies account for a very large percentage of the index. Companies such as Apple, Microsoft, NVIDIA, Amazon, Alphabet, Meta, Tesla, Broadcom, Berkshire Hathaway, and UnitedHealth collectively represent a substantial portion of the market’s value. These are undoubtedly great businesses, but the key question for investors is not simply whether a company is great. The real question is:
Are they great investments at today’s valuations?
In this video Chuck will cover Apple Inc (AAPL), Nvidia Corp (NVDA), Amazon (AMZN), BroadcomInc (AVGO), Berkshire Hathaway Inc (BRK.B), Alphabet (GOOGL), Meta Platforms(META), Microsoft Corp (MSFT), Tesla (TSLA), UnitedHealth Group (UNH), KraftHeinz (KHC)
A concept I stress frequently is that a great company does not automatically equal a great investment. Investors must always consider the relationship between price and value.
Valuation ultimately determines the rate of return an investor can reasonably expect. When prices become disconnected from underlying fundamentals such as earnings and cash flows, future returns may fall short of expectations—even if the business itself continues to perform well.
This is why valuation matters.
Understanding Earnings Yield
One of the most useful ways to think about valuation is through earnings yield, which is simply the inverse of the price-to-earnings (P/E) ratio.
If you bought the entire company, earnings yield represents the percentage return you would theoretically receive on your investment based on current earnings.
For example:
A P/E ratio of 20 equals a 5% earnings yield
A P/E ratio of 30 equals roughly a 3.3% earnings yield
When earnings yields become very low, investors are effectively paying a high price for future growth. That may work if growth remains extraordinary, but it can also create significant risk if growth slows.
The Impact of Slowing Growth
Many of today’s largest companies achieved exceptional growth in earlier stages of their development. However, as businesses become extremely large—often worth trillions of dollars—it becomes increasingly difficult to maintain the same growth rates.
This phenomenon is sometimes referred to as the law of large numbers.
For example, a company that previously grew earnings at 25% annually may eventually see growth slow to 10–15%. While that is still impressive for a large company, it often does not justify extremely high valuation multiples.
When growth slows but valuations remain elevated, future returns may decline.
The Relationship Between Growth and Valuation
Historically, many investors have used a simple concept popularized by Peter Lynch: A company’s fair valuation often approximates its growth rate.
In other words:
Faster growth can justify higher valuation multiples
Moderate growth generally warrants more moderate valuations
If investors pay far above that relationship, they may not fully participate in the company’s future growth because the starting valuation is simply too high.
Understanding the FAST Graphs Score
Another topic raised by viewers involves the FAST Graphs Score, which evaluates companies across several key categories:
Profitability
Predictability
Financial strength
Growth
Cash flow generation
These factors combine to provide a snapshot of overall business quality. However, it is important to remember that no single score should replace deeper analysis. Investors should always explore the underlying fundamentals behind any rating.
FAST Graphs allows investors to drill into these metrics in detail and see how a company’s performance has evolved over time.
Market Efficiency and Investor Discipline
One common misconception in investing is that the market always prices stocks correctly. In reality, markets can become overly optimistic or pessimistic for extended periods.
Investor enthusiasm can drive valuations well above fundamental value, especially when a company captures public attention or becomes associated with a powerful trend such as artificial intelligence or technological disruption.
While this momentum can persist for years, eventually the relationship between price and fundamentals tends to reassert itself.
Final Thoughts
The key takeaway from this discussion is simple but critically important:
Investors should focus not on what a company “deserves,” but on what they deserve as investors when committing their capital.
Even the best companies in the world can become risky investments if purchased at excessive valuations. Conversely, solid businesses purchased at reasonable prices can produce attractive long-term returns.
By focusing on earnings, growth, and valuation, investors can better position themselves to participate in the long-term wealth creation that successful businesses generate.
