Long story short, Warren Buffett did not make his first million through diversification.
When did Warren Buffett start investing?
Warren Buffett was born on August 30, 1930, in Omaha, NE. He is considered one of the most successful investors in the world and has a net worth of over $150B as of 2026.
In 1954, at age 24, one of his first jobs was working at Benjamin Graham’s investment partnership for a salary of $12,000/year USD (Over $140,000/year in today’s dollars). Graham was one of Warren Buffett’s professors at Columbia Business School, and he wrote the popular investing book, The Intelligent Investor.
In 1956, Benjamin Graham retired and closed his partnership, and Warren Buffett established Buffett Partnership Ltd, which was a wealth management firm that invested in private companies as opposed to public companies (stocks).
In 1957, at age 27, Warren Buffett bought his five-bedroom stucco house in Omaha, NE, for $31,500 (Over $350,000 in today’s dollars). He still lives in the same house today.
In 1959, at age 29, he met his future business partner, Charlie Munger.
How does Warren Buffett make money?
Unlike today, where most wealth management firms charge approximately 1% – 2% AUM (Assets Under Management), Warren Buffett charged 0% AUM but charged 25% commission beyond a 6% cumulative return.
The firm’s average returns from 1957 through 1968 were 31.6%, with no negative years.
His strategy, as learned from Benjamin Graham, was to buy a small portfolio of 10 – 15 value stocks. In other words, a focused portfolio of financially strong businesses.
One key to finding value stocks is to calculate the Fair Value (intrinsic value) of a stock and make sure you buy that stock for 50% off, or in other words, a 50% Margin of Safety. Essentially, it’s like buying $10 bills for $5.

How did Warren Buffett make his first million?
So, how did Warren Buffett make his first million?
With Buffett Partnership Ltd, he owned a small, focused portfolio of about 10 businesses and kept investing in those same businesses over time. The keyword is “focused”. At this point in his life, he did not diversify.
By 1962, at age 32, his net worth exceeded $1 million (Over $10M in today’s dollars) because of a focused portfolio that earned over 30% per year.
The key to building his first million can be summarized in two steps:
Step 1) Own about 10 businesses
Step 2) Keep buying those businesses every month! Do not skip months.
How did Warren Buffett become a billionaire?
By this time, Warren Buffett’s momentum of wealth-building had just started.
In 1962, he began buying shares of Berkshire Hathaway, which at the time was a textile (fabric) manufacturing company founded in 1839.
In 1964, Berkshire Hathaway’s stock was dropping due to the textile industry decline. Warren Buffett decided to seize the opportunity and buy majority ownership of Berkshire Hathaway.
In 1969, at age 39, Warren Buffett closed down Buffett Partnership Ltd because he admitted to his investors that he had run out of good ideas to beat market returns. At this time, he decided to focus his attention on building the share price of one company, Berkshire Hathaway.
Fast forward to 1985, the last textile operation under Berkshire Hathaway was shut down; however, Warren Buffett kept the name Berkshire Hathaway. By this time, Berkshire Hathaway had a focused portfolio of less than 20 companies. By maintaining a focused portfolio and reinvesting capital into these same companies every month, he was able to achieve market-beating returns and significantly accelerate his wealth-building process.
In 1986, at age 56, Warren Buffett officially became a billionaire.
Berkshire Hathaway eventually turned into a conglomerate that would buy and hold private companies, including GEICO, Duracell, Dairy Queen, Fruit of the Loom, and Pampered Chef. Berkshire Hathaway also owns shares in public companies, including Kraft Heinz, American Express, Coca-Cola, Bank of America, and Apple. Today, you may purchase shares of Berkshire Hathaway under ticker symbols BRK-A or BRK-B.
A reflection on a big mistake (that could have made Warren Buffett more money)
In 2010, Warren Buffett claimed that purchasing Berkshire Hathaway was the biggest investment mistake he had ever made and said that it had denied him compounded investment returns of about $200 billion over the subsequent 45 years. Warren Buffett said that had he invested that money only in insurance businesses instead of buying out Berkshire Hathaway, those investments would have paid off several hundredfold.
In 2026, BRK-A trades at over $700,000 per share, and BRK-B trades at over $400 per share. Essentially, BRK-B allows you to invest in Berkshire Hathaway with a much lower barrier to entry.
Over time, Berkshire Hathaway continued to buy more stocks and transitioned from “wealth building” to “wealth protection.”
As of 2026, Berkshire Hathaway owns over 40 stocks and has a market cap of over $1 trillion.
As taught by Warren Buffett…
- Wealth building = Own a focused portfolio of 10 – 15 stocks
- Wealth protection = Own a diversified portfolio of 30 stocks
