Mistakes are inevitable and no one avoids them. How you react to them is more important. Fisher made them. They were concentrated at the beginning and end of his investing career. Early mistakes are inevitable. Most investors learn nothing, but the best ones learn even more. They have learned more from mistakes than from success, and successful investors are no exception. Fisher's late-career mistakes, according to his son, were largely due to his poor health.
Fisher was also a victim of the great stock market crash that began in 1929. He thought stock prices were expensive, but he still put his money in three stocks that seemed cheap with low P/E ratios. He lost almost all of his investments by 1932. He put his money in a locomotive manufacturer, a roadside advertising company, and a taxi company. From this he learned that a seemingly cheap price does not guarantee a successful investment. It can be a sign of weakness. Fisher also tried market timing three times. Each time, he made profits, but found them too small for his time, so he stopped the business when it was unprofitable. In addition, he struggled in the early days to set a suitable purchase price. As a result, he often missed out on stocks that would have brought him big profits.
It is not easy to expose errors in thinking, but I think Fisher’s belief in the importance of top management in good investments is excessive. To quote Buffett, “when a company with a bad reputation meets a company with a good reputation, the company’s reputation is what remains.” I think Fisher never understood that human irrationality can lead to a lasting competitive advantage. This is one reason why he was not good at investing in companies that sell consumer goods. On the other hand, he was good at focusing on the companies that he understood best.
Constantly worrying about everything bad was a characteristic of Fisher. It made him feel more secure. Even small details could make him worry about the risks associated with an investment. This made him abandon many investments because he did not dare to take even small risks associated with them. His returns were lower due to this character trait. He did not dare to take as calculated risks as many other top investors.
Summary
Fisher was the father of qualitative thinking. His process was long and demanding. It is not for everyone. It is easier to implement if you are extroverted and ready to talk. For introverts, it is difficult and perhaps too demanding. I do not recommend it for them. Fisher succeeded well at it for one reason or another, so it is not impossible for those who do not care about other people. Fisher believed that luck equals in the long run, so for him, continued investment success depends on skill and sound principles. Fisher's book Developing An Investment Philosophy contains eight principles that he used, which crystallize his investment philosophy:
1. Buy stocks of companies that have disciplined plans for long-term profit growth and the inherent qualities to let others enjoy their profits.
2. Focus on the above-mentioned companies when they are not popular in the market.
3. Hold the shares until the company undergoes significant changes or has grown to a point where it cannot be expected to grow faster than the general economic situation.
4. Investors focused on appreciation should downplay the importance of dividends, because the best opportunities for returns are found in profitable companies that pay little or no dividends.
5. Making mistakes is a necessary price to pay for large investment profits.
6. There are a limited number of great companies. Their shares are usually not available at attractive prices, so the investments must be large when the opportunities arise. Investments should be concentrated only in the best targets. Owning more than 20 shares indicates incompetence.
7. The basic ingredient of investment management is not to directly accept the views of investors or to oppose them without understanding reality.
8. Success in stock investing depends on hard work, intelligence and honesty.
