Michael Merlin: Understanding Business Models is Key to Sound Investing

In a recent LinkedIn post, Michael Merlin shares a foundational principle for smart investing: the absolute necessity of understanding the businesses one invests in. Merlin emphasizes that superficial factors like market hype or a charismatic CEO are poor substitutes for genuine comprehension of a company’s operations and revenue streams.

Merlin’s core message revolves around the idea that true investment success stems from knowledge, not just excitement. He writes:

Never invest in a business you cannot understand. A great story does not make a great investment.

The post systematically breaks down common pitfalls that can lead investors astray, arguing that a lack of understanding significantly increases risk. Merlin highlights several factors that should never be the sole basis for an investment decision:

• A rising stock price
• Market hype
• A popular CEO
• Widespread discussion about the company

The Importance of Business Model Comprehension

Merlin argues that if an investor cannot clearly explain how a company generates its revenue, they are ill-equipped to assess its potential risks and rewards. He outlines a series of critical questions potential investors should ask themselves before committing capital:

1. What does the company sell?
2. Who pays for it?
3. Why do customers choose it?
4. How does it generate cash?
5. What gives it a competitive advantage?
6. What could seriously hurt the business?

According to Merlin, while deep technical expertise isn’t always required, a solid grasp of the business model is non-negotiable. He cautions against the allure of exciting prospects, stating:

The mistake is investing because something looks exciting. Excitement can attract attention. Understanding helps protect capital.

Adhering to the Circle of Competence

Merlin draws a direct parallel to Warren Buffett’s well-known philosophy of investing within one’s “circle of competence.” This principle, as explained by Merlin, is straightforward: if an investment cannot be articulated in simple terms, further research is warranted. He stresses that the investment landscape is vast and opportunities are plentiful, negating the need to invest in every trending company.

“You don’t need to invest in everything. You need to understand what you own,” Merlin asserts, reinforcing the idea that informed ownership is paramount. His concluding advice is unequivocal: “Know the business before you buy the stock.” This focus on fundamental understanding, Merlin suggests, is the most reliable path to protecting invested capital and achieving long-term financial goals.
