November 30th anniversary
On November 30, 1958, Phillip Fisher published Common Stocks and Uncommon Profits, an investment guide that is still relevant today and helped none other than Warren Buffett in his early days. Let's see what we can learn from this magnificent book.
Common Shares and Extraordinary Profits Philip Fisher's The Book of Investing is one of the classic investment texts that has influenced generations of investors, including Warren Buffett. In this book, Fisher presents his unique approach to selecting stocks based on a qualitative analysis of companies, rather than focusing solely on financial data. The most important practical lessons from the book are summarized below.
1. The Importance of the Qualitative Approach
Fisher emphasizes that successful investing isn't based solely on numbers or financial analysis, but on a deep understanding of the company and its intangible qualities. A qualitative analysis can help identify whether a company has characteristics that allow it to grow over the long term and generate extraordinary profits. These qualities include the capacity for innovation, the quality of management, the effectiveness of operations, and the relationship with employees and customers.

2. The 15 Points for Evaluating an Action
One of the book's most valuable contributions is the list of 15 criteria Fisher suggests using to evaluate stocks, which can be divided into areas such as sales generation capacity, operational efficiency, management, and innovation. Some of the most important are highlighted below:
- Sales growth potential: Fisher looks for companies that are in an industry with significant growth potential, or that have the capacity to develop new products or services that can significantly expand their sales.
- Management capacity: Good management must be able to adapt to market changes, and management must demonstrate integrity and competence. Fisher also values a corporate culture that encourages experimentation and continuous improvement.
- Profit margin: Not only sales growth should be considered, but also the company's ability to maintain or improve its profit margins. A company with high margins is better able to withstand adverse economic cycles.
- Employee Relations and Hiring Policy: A company that invests in its people and has a hiring policy that encourages talent retention and development can be more resilient and efficient in the long term.
- Quality of products and services: Companies with products or services that have a clear advantage over the competition can achieve higher margins and sustainable growth.
- Analysis of profit and dividend history: Fisher maintains that a history of solid, growing profits is a good indicator, but not necessarily a determining factor. He prefers companies that reinvest their profits to generate further growth rather than distributing high dividends.
3. The "Buy and Hold" Philosophy
Fisher advocates a long-term "buy and hold" strategy rather than trying to time the market. For him, the best investment opportunities are found in companies with long-term growth potential, and investors must have the patience to allow that growth to materialize. Short-term volatility shouldn't be a concern if a solid company with good growth potential has been selected.
4. The Scuttlebutt Technique
One of Fisher's most distinctive techniques is what he calls "scuttlebutt," which involves thoroughly investigating a company through conversations with people who have knowledge of it. This can include current or former employees, competitors, customers, suppliers, and even industry experts. The idea is to gather information about the quality of management, products, and the company's situation that is not easily accessible through financial reports.
5. The Importance of Innovation and Research
Fisher places great emphasis on a company's capacity for innovation. Companies that consistently invest in research and development (R&D) to improve their products or create new ones are better candidates for generating extraordinary profits over the long term. However, he cautions that R&D investment must be selective and effectively targeted, as not all innovations generate real value.

6. Avoid Excessive Diversification
Fisher is critical of excessive diversification, believing it dilutes the deep knowledge an investor may have about a company. He believes it's better to concentrate investments in a few well-selected companies with high growth potential than to disperse capital across many companies with little in-depth analysis. The key is to select quality companies and hold them for the long term.
7. Don't Fear High Stock Prices
Unlike many investors who seek out "cheap" stocks, Fisher maintains that there's no need to be afraid of paying high prices for shares of exceptional companies, as long as the potential for future growth justifies the current price. He prefers to invest in companies with high market prices if he believes their fundamental qualities can generate significant future growth. It's more profitable to pay a fair price for an excellent company than a low price for a mediocre one.
8. Learn from Mistakes
Fisher admits that even the best investors make mistakes and that it's important to learn from them to improve in the future. By analyzing investments that have gone wrong, you can identify patterns of behavior or signals that were overlooked and avoid making the same mistakes in the future.
9. Patience is Key
The book emphasizes the importance of patience in investing. According to Fisher, most investors fail because they aren't patient enough to allow investments to mature. Sticking to the "buy and hold" approach is essential to capturing long-term growth from well-selected companies.
10. Analyze the Competition
Fisher argues that competitive analysis is critical to assessing a company's position in its industry. A company with enduring competitive advantages, such as a strong brand, low production costs, or an efficient distribution network, is better positioned to face market pressures. Competitive advantage acts as a barrier to entry for other competitors and can protect long-term profitability.
11. Evaluate Leadership Effectiveness
The effectiveness of a company's leadership is a crucial factor for Fisher. He emphasizes that good leadership is reflected not only in the company's financial management, but also in the ability to inspire and manage teams, adapt to market changes, and make sound strategic decisions. For him, management that demonstrates long-term vision and responsible decision-making is indicative of a solid company.
12. Importance of Adaptability
Fisher emphasizes the importance of a company's adaptability to survive and thrive in a changing business environment. Companies that are too rigid and fail to adapt to new technologies, changes in demand, or regulations are more likely to fail. The ability to continually evolve and improve is essential for long-term success.
In summary
In "Common Stocks and Outstanding Profits," Philip Fisher provides an investment approach based on quality and in-depth analysis of companies, rather than focusing solely on numbers. His lessons include the importance of seeking value in companies with strong growth potential, the need for thorough research (scuttlebutt), and the patience to maintain long-term investments. He also highlights the importance of innovation, effective leadership, and adaptability in business, as well as the need to avoid excessive diversification and not be afraid to pay high prices for quality stocks.
These lessons remain relevant for investors today, as they provide a guide to identifying companies that are not only performing well today but also have the potential to generate extraordinary returns in the future.
