Buffett
Overview
'Buffett' generally refers to the American investor Warren Edward Buffett (born August 30, 1930). He leads the holding company Berkshire Hathaway and has recorded returns exceeding the market average for more than half a century, earning him the nickname the 'Oracle of Omaha.' He is regarded as a symbolic figure of value investing and one of the most influential philanthropists in the world.

Life and Background
Warren Buffett was born in 1930 in Omaha, Nebraska, USA. His father, Howard Buffett, was a stockbroker and later a U.S. Representative, and from an early age Warren naturally developed an interest in stocks and businesses. The anecdote that he bought his first stock at age 11 is well known. He studied under Benjamin Graham at Columbia Business School, and Graham's books 《Security Analysis》 and 《The Intelligent Investor》 became the roots of Buffett's investment philosophy. In 1956 he founded the 'Buffett Partnership' and gained recognition for his management performance, and in 1965, after securing control of Berkshire Hathaway—then a textile manufacturer—he transformed it into an investment holding company.
Berkshire Hathaway
Berkshire Hathaway is a conglomerate with a diverse range of subsidiaries in insurance (GEICO, General Re), railroads (BNSF), energy (Berkshire Hathaway Energy), and consumer goods, manufacturing, and services. Buffett perfected a structure in which he uses the 'float' generated by Berkshire's insurance business as low-cost capital to acquire and invest in high-quality companies. In August 2024, it surpassed a $1 trillion market capitalization, becoming the first non-tech American company to enter this territory.
Investment Philosophy
- Value Investing: Buys companies undervalued relative to their intrinsic value and is not swayed by short-term market fluctuations.
- Economic Moat: Prefers companies with sustainable competitive advantages such as brand, economies of scale, and switching costs.
- Long-Term Holding: As in the saying, "Our favorite holding period is forever," long-term holding is a principle.
- Circle of Competence: Does not invest in industries he does not understand. This is also why he long avoided investing in tech stocks.
- Contrarianism: Emphasizes the principle, "Be fearful when others are greedy, and greedy when others are fearful."
- Evaluation of Management: Values competence, honesty, and shareholder-friendliness, and shows an attitude of respecting management when making acquisitions.
Representative Investment Cases
- Coca-Cola (1988): A large-scale purchase based on brand power, which became a representative case of long-term holding thereafter.
- American Express, Wells Fargo: Achieved large profits through contrarian investments during crisis situations.
- Apple (after 2016): Changed his previous stance on tech stocks and made a large-scale investment, which at one point accounted for a significant portion of Berkshire's portfolio.
- Japan's five major general trading companies (2020~): Bought stakes in Itochu, Mitsubishi, Mitsui, Sumitomo, and Marubeni, and issued yen bonds to manage currency risk.
Writings and Quotes
Buffett is famous for the 'Shareholder Letter' he publishes every year, which is one of the most widely read investment primers among investors. It has also been compiled into works such as 《Warren Buffett's Shareholder Letters》. His partnership with Charlie Munger played a decisive role in completing Buffett's philosophy.
Philanthropy
In 2006, he announced that he would donate about 85% of his wealth to charitable organizations, and in 2010, together with Bill Gates, he co-founded 'The Giving Pledge' to encourage the world's wealthy to participate in philanthropy.
Latest Trends
The changes from 2024 to 2025 can be summarized as 'succession and securing cash.'
- Large-Scale Cash Assets: Buffett gradually reduced his Apple stake and increased cash-equivalent assets such as U.S. Treasuries to a record-high level (over about $330 billion as of the end of 2024). Market valuation burdens and the absence of large-scale acquisition opportunities are interpreted as the background.
- Formalization of CEO Succession: At the shareholders' meeting in May 2025, Buffett announced that he would hand over the CEO position to Greg Abel at the end of the year and remain as chairman. It is a turning point for a management system that has lasted for nearly 60 years.
- Changes in the Shareholders' Meeting: The 2025 meeting drew large-scale attention as the last meeting Buffett presided over as CEO.
- Continued Investment in Japan: He maintains a long-term investment stance, stating his intention to hold the general trading company stakes for 50 years.
- Market Influence: Buffett's remarks and Berkshire's quarterly reports still act as major variables in global stock markets, and the expansion of the cash ratio is sometimes interpreted as a signal of economic slowdown.
Despite these changes, Buffett's investment principles themselves have not changed significantly, and Berkshire Hathaway remains an organization that institutionalized his philosophy.
