When people talk about legendary investors, two names almost always come up: Warren Buffett and Benjamin Graham. While they had different investment strategies, their philosophies are deeply connected and shaped how modern investing works today.
Warren Buffett: A Long-Term Mindset
Warren Buffett was born in 1930 in Omaha, Nebraska, and went on to become one of the most successful investors of all time. His disciplined investment decisions came from carefully studying a company’s financials, especially its assets, debt, and long-term stability, rather than following market trends or speculation.
He studied at the University of Nebraska and later at Columbia University, where he learned under Benjamin Graham. That education played a major role in shaping the principles he still follows today.
Building Berkshire Hathaway
In the 1960s, Buffett took control of a struggling textile company called Berkshire Hathaway and transformed it into his primary investment vehicle. Instead of focusing on short-term profits, he used the company to acquire strong businesses and hold them long-term.
From the 1960s to the 1990s, Berkshire Hathaway’s stock grew at an average annual rate of approximately 28%. This growth was a direct result of the consistent decision-making practices he used, patience, and a strict focus on investing in quality businesses with larger assets than debt.
Values Beyond Wealth
Despite his massive success, Buffett is known for living modestly and advocating for higher taxes on the wealthy. According to Britannica, he has committed to donating 99% of his wealth, much of it through foundations focused on global health, education, and social causes. His children now help run organizations that support similar missions.
During the 2007–2008 financial crisis, Buffett made several major investments that helped stabilize struggling companies and restore confidence in the market. While many investors panicked, he remained focused on long-term value.
Buffett’s Core Investment Beliefs
One of Buffett’s strongest beliefs is that investors should not try to time the market. One of his recommendations for value investing includes ignoring short-term market noise and focusing on owning strong businesses for the long run.
He also strongly warns against high-interest debt, especially credit cards. Paying 18–20% interest, as he’s pointed out, makes it extremely difficult to build long-term wealth. This advice has personally shaped how I think about spending, saving, and investing.
Benjamin Graham: The Foundation of Value Investing
Benjamin Graham is often called the “father of value investing.” He began his successful career on Wall Street before becoming a professor at Columbia University, where he later taught Warren Buffett.
Graham’s investment philosophy focused on protecting capital first and pursuing growth second. Having lived through multiple market crashes, he valued stability, strong balance sheets, and realistic expectations over speculation.
The Margin of Safety
One of Graham’s most important ideas is the margin of safety: buying a stock at a significant discount to its intrinsic value. This helps reduce downside risk and provides more protection to investors from lapses in judgment or unexpected market changes.
In Graham’s time, this sometimes meant buying companies whose liquid assets were worth more than their market value. Opportunities like the ones he had are rare today; however, the principle still applies. Buy quality assets at reasonable prices and leave room for error.
Understanding “Mr. Market”
Graham introduced the idea of Mr. Market, an imaginary business partner who offers to buy or sell shares every day at different prices depending on his mood. Some days he’s optimistic, other days he’s pessimistic, but the main idea is that his emotions shouldn’t dictate your decisions.
The lesson is simple: investors should rely on their own analysis rather than reacting to market swings or headlines.
Applying Their Ideas in Today’s Market
Although markets today move faster and are influenced by algorithms, news cycles, and social media, the principles of Buffett and Graham still apply.
Modern investors can apply their teachings by:
- Focusing on strong, financially stable companies
- Avoiding emotional decision-making
- Investing consistently instead of trying to time the market
- Diversifying to manage risk
- Thinking long-term rather than chasing short-term gains
While value investing looks different today than it did decades ago, the foundation remains the same: discipline, patience, and understanding what you own. You can read more about this in my post on How To Invest: Understanding Risk.
Final Thoughts
What stands out most about Warren Buffett and Benjamin Graham is their consistency. They focused on fundamentals, long-term thinking, and disciplined decision-making, not chasing trends or trying to read the market.
Their philosophies show that successful investing isn’t about predicting the future, but about making informed choices and sticking with them over time.
