The circle of competence describes a person’s natural competence in an area that matches their skills and abilities. Beyond this imaginary circle are skills and abilities that a person is naturally less competent at. The concept was popularised by Warren Buffett, who argued that investors should only invest in companies they know and understand. However, the circle of competence applies to any topic and indeed any individual.
| Aspect | Explanation |
|---|---|
| Circle of Competence | The Circle of Competence is a concept popularized by legendary investor Warren Buffett. It represents the boundary or scope of an individual’s or organization’s expertise and knowledge in a specific area or industry. |
| Warren Buffett’s Insight | Warren Buffett advises investors to stay within their Circle of Competence when making investment decisions. He suggests that investors should focus on industries and companies they understand deeply to make informed and successful investments. |
| Scope of Expertise | An individual or organization’s Circle of Competence defines the areas where they possess deep knowledge, skills, and experience. It encompasses industries, sectors, markets, or specific business activities where they excel and have a competitive advantage. |
| Importance | Recognizing and staying within one’s Circle of Competence is crucial for making informed decisions and avoiding costly mistakes. Straying outside of this circle can lead to poor judgment and investments that are based on incomplete information. |
| Expanding the Circle | While it’s essential to stay within one’s Circle of Competence, individuals and organizations can gradually expand their expertise through learning and experience. Buffett himself has expanded his circle over the years but emphasizes patience and caution. |
| Investment Analogy | In investment, the Circle of Competence is particularly relevant. Buffett suggests that investors should invest in businesses they understand thoroughly, assessing the company’s fundamentals, competitive position, and long-term prospects within their circle. |
| Risk Mitigation | Staying within the Circle of Competence helps mitigate risks associated with unfamiliar industries or activities. It reduces the likelihood of making poor investment decisions based on incomplete or inaccurate information. |
| Examples | Examples of the Circle of Competence in practice include a tech-savvy investor focusing on technology stocks, a healthcare professional investing in pharmaceutical companies, or a retail expert concentrating on the retail industry. |
| Business Application | Beyond investing, the Circle of Competence concept applies to business decisions. Companies should focus on their core competencies and industries where they have expertise to maintain a competitive edge and make sound strategic choices. |
Understanding the circle of competence
It is useful to think of the circle of competence as a small circle within a much larger circle.
The larger circle represents what an individual thinks they know but are far from an expert in.
Conversely, the smaller circle represents what they actually know and could be considered an expert in.
Buffet’s strategy for success in life using the circle of competence relatively simple.
Firstly, it is important that individuals know where the boundary of their inner circle is. Once the boundary has been established, it must not be crossed.
Buffet’s business partner Charlie Munger took the circle of competence one step further.
He argues that a person must clarify their individual strengths and then play to them to have a competitive advantage.
If a person not playing to their strengths comes up against a person who is, they will most likely lose.
However, it is a natural tendency for many individuals to deliberately step outside of their circles or attempt to broaden them.
The circle can be expanded to an extent, but skills are usually industry-specific and non-transferable to other industries.
In business, this is why some organizations divest or outsource operations that don’t align with their core business.
Examples of the circle of competence
In a 1991 lecture to university students, Buffet reflects on the circle of competence of a Russian immigrant who built the largest furniture store in Nebraska.
Buffet noted that this woman understood cash and furniture selling. Therefore, her circle of competence was furniture and specifically a talent for buying large amounts of furniture to turn a profit.
Despite also being a business partner of his, Buffet noted that this woman had no interest in the stock market.
The circle of competence explains why. She was disinterested because she did not understand how it worked.
Indeed, Buffet would later exclaim that “she wouldn’t buy 100 shares of General Motors if it was 50 cents a share.”
Furthermore, consider the Olympic athletes Michael Phelps and Hicham El Guerrouj.
The first is a gold medal-winning swimmer, the second a gold medal-winning runner.
Despite the athletes differing in height by 7 inches, the length of their legs is almost identical. Phelps with relatively short legs and a long torso that is perfect for moving through water.
El Guerrouj has relatively long legs and a short torso that is perfect for long-distance running.
Each man operates within his circle of competence, and each has been highly successful.
If the two were to switch sports and move beyond their circles, it would be highly unlikely that either would succeed to the extent they have.
