Who is Warren Buffett? A brief history
Warren Buffett was born on August 30, 1930, in Omaha, Nebraska. Since he was a child he showed a special nose for business: at the age of six he bought packets of chewing gum and sold them door to door.
At eleven he made his first investment in the stock market. The son of a congressman and stockbroker, he studied at Columbia University under the tutelage of Benjamin Graham, the father of value analysis. That experience forever marked his way of investing.
After working at Graham’s firm, Buffett returned to Omaha in 1956 and founded his own investment firms
In 1965 he took control of Berkshire Hathaway, a declining textile company, and turned it into a conglomerate that is now worth more than a trillion dollars.
Although on December 31, 2025, he officially left the position of CEO to Greg Abel, he remains chairman of the board and the intellectual soul of the company.
His net worth hovers around $150 billion, but he has donated more than $65 billion to charitable causes.
The Investment Philosophy: Timeless Principles
The key to Warren Buffett’s success is not algorithms or high-frequency trading, but a rock-solid philosophy. These pillars allow us to act even in an overvalued market such as the one we are currently experiencing. These are its five pillars:
- Invest in value with a margin of safety: buy solid companies below their intrinsic value, creating a cushion that protects even if forecasts fail.
- Operate in the “circle of competence“: never invest in a business that cannot be perfectly understood. That is why he has avoided technologies that he did not master for decades.
- Eternal horizon: “our favorite holding period is forever.” Compound interest only works if given time. It exemplifies its “buy and hold” strategy, allowing the power of compound interest to work its magic over the years
- Temperament over intelligence: the disciplined investor wins over the impulsive. Patience and cool-headedness are worth more than a high IQ.
- Remain calm: Knows how to take advantage of the volatility of others, being fearful when others are greedy and greedy when others are afraid
In his latest letter to shareholders, Buffett summed up his motto: “Adapt to reality, because reality will not adapt to your risk tolerance.”
The effectiveness of Warren Buffett’s management: numbers that speak for themselves
If anyone doubts the effectiveness of his method, just look at the figures.
From 1965 to 2024, Berkshire Hathaway achieved a compound annual return of 19.9%, while the S&P 500 barely reached 10.4%. That means an investment of $10,000 in 1965 would have turned into more than $550 million.
Although Berkshire’s profitability in 2025 was 10.9%, slightly below the index’s 16.4%, the company posted its tenth consecutive year in the red.
The Class A stock, which was worth about $19 when Buffett took control, closed 2025 near $750,000.
Under his leadership, Berkshire Hathaway transformed into a conglomerate valued at more than a trillion dollars, with stakes in iconic companies such as Coca-Cola, American Express and Apple
These numbers are not the result of luck, but of an iron discipline applied for six decades.
What We Can All Learn From Warren Buffett?
The story of Warren Buffett is not that of a lone genius, but that of a man who knew how to surround himself with the best (like Charlie Munger), stay calm when everyone lost their minds and never stop learning.
His philosophy, based on courage, patience and the circle of competence, is still as valid in 2026 as it was in the sixties. For Gustavo Mirabal Castro, Warren Buffett is an inspiration in the way of doing business and investing.
Even in the face of new challenges such as artificial intelligence or geopolitical volatility, its principles offer solid guidance: invest in what you understand, buy quality at a reasonable price, and think decades.
If the Oracle of Omaha has taught us anything, it is that true wealth is not built in haste, but with conviction and perseverance. Are you ready to apply these lessons in your own portfolio?
