[Super Introduction] Learn from the World's 3 Greatest Investors! The Wisdom and Philosophy of Warren Buffett, George Soros, and Jim Rogers

When you start trying to invest, you will inevitably hear the term “World’s 3 Greatest Investors.” Do you think, “Stories about geniuses sound too difficult” or “That has nothing to do with me”?

Their investment methods are all different and unique. However, the basic philosophies and ways of thinking they have built serve as a compass that will be useful for a lifetime, even for beginners who have just started with New NISA or index investing.

In this article, we will explain three people in a way that is easy for beginners to understand: Warren Buffett, who stepped down as Chairman on September 18, 2026; George Soros, who created a legend by taking on the Bank of England; and Jim Rogers, who travels the world to identify real value.

1. Warren Buffett: The God of Long-Term Investing and Compound Interest

The “Sage of Omaha” who made time his ally more than anyone else

Warren Buffett is a legendary investor who has led Berkshire Hathaway, the world’s largest investment holding company. On September 18, 2026, having reached the age of 96, Buffett officially stepped down as Chairman of the Board of Berkshire and became Chairman Emeritus. It was a moment that marked a milestone in his history as a top active leader for over 60 years.

His hallmarks are “value investing” and “ultra-long-term holding.” He built immense wealth by buying good companies at fair (or undervalued) prices and holding them for decades.

Buffett’s core: The sense of “buying a business”

Buffett does not follow stock charts or daily price movements. This is because he believes that “buying a stock is owning a piece of that business.”

• Choose companies with a strong “Moat”: He prefers companies like Coca-Cola or Apple that have brand power or a customer base that others cannot easily imitate.

• Only invest in businesses you can understand: He maintained strict discipline, never touching trendy high-tech companies or opaque financial products, even when others were enthusiastic.

Lessons for beginners

• Do not panic during a crash: “Be fearful when others are greedy, and greedy when others are fearful.” When the market drops sharply, it is the perfect opportunity to acquire high-quality assets at a low price.

• Believe in the power of compound interest: Over 99% of Buffett’s wealth was built after the age of 50. Starting early and staying in the market for a long time is the greatest weapon in asset formation.

2. George Soros: The “King of Macro Investing” who exploits market distortions

George Soros is a pioneer of the “Global Macro” method, which involves analyzing major economic trends (interest rates, exchange rates, and national financial policies) and investing massive amounts of capital.

It was the “Black Wednesday” of 1992 that propelled his name to global fame. Recognizing that the British pound was overvalued at the time, Soros launched a massive short-selling campaign against the currency. The Bank of England (the UK’s central bank) fought desperately to support its currency, but it could not hold the line and was ultimately forced to withdraw from the European Exchange Rate Mechanism (ERM). As a result, Soros made over $1 billion in just a few days and was etched into history as “the man who broke the Bank of England.”

The Core of Soros: “Reflexivity Theory”

Soros, who once aspired to be a philosopher, brought his unique “Reflexivity Theory” into the market.

• The market is always wrong (biased): A cycle is created where the expectations and assumptions of market participants move actual prices, and those moved prices further influence people’s psychology.

• Exploiting the birth and collapse of bubbles: He identifies the process by which unrealistic prices (bubbles) are created by people’s biases and eventually corrected, then takes bold positions.

Lessons for Beginners

• Admit mistakes flexibly: Soros’s true strength is not “getting predictions right,” but “being able to cut losses immediately the moment he realizes he is wrong.” Only investors who can discard their pride and admit their own faults can survive in the market.

• Do not get caught up in herd mentality: It is important to know that the frenzy of “it must be going up because everyone is buying” is often inflated by bias (assumptions) rather than objective reality.

3. Jim Rogers: The “Adventure Investor” who travels the world on his own feet

A unique career of traveling the globe by motorcycle and car

Jim Rogers is a genius who once co-founded the “Quantum Fund” with George Soros and achieved a staggering return of 4,200% (about 42 times) over 10 years.

After retiring from the fund at age 37, he set off on a trip around the world by motorcycle and a custom-made Mercedes-Benz. This journey, which was also recognized by the Guinness World Records, was not just sightseeing, but “field research to verify the situation in each country with his own eyes.”

The Core of Rogers: “Fieldwork” and “Commodities”

Rogers’ investment philosophy is extremely simple. It is an approach of “seeing with your own eyes, learning history, and finding undervalued targets that the masses are pessimistic about.”

• Trust primary information from the field: Instead of taking news and analyst reports at face value, he judges investment targets by directly observing the inventory of local shops, people’s clothing, and currency exchange conditions.

• Focus on commodities (real assets): He emphasizes the supply and demand cycles of resources such as oil, agricultural products, and precious metals, and has continued to advocate for the strength of real assets that maintain their value even when financial assets are eroded by inflation.

• Reading historical cycles: He is also known for having early on identified the shift in civilizational and economic hegemony from the British Empire to America and then to Asia, and for actually moving his residence to Singapore.

Lessons for Beginners

• Pick up hints in your own living environment: The attitude of “not investing in things you don’t know well” and “observing what is trending around you and what is falling out of use” is the approach that individual investors can most easily emulate.

• Learn from history: Economic booms and busts repeat themselves over and over in different forms. By learning from history, you can acquire a long-term perspective that prevents you from being swayed by short-term news.

Comparing the characteristics of the three at a glance

The common essence: ‘3 iron rules’ that beginners should adopt starting today

At first glance, the methods of Buffett, who holds for the long term, Soros, who exploits distortions in the short to medium term, and Rogers, who emphasizes on-the-ground reality and commodities, seem like opposites. However, there are common ‘winner’s rules’ shared by these three who reached the pinnacle of the world.

1. Stay within your ‘circle of competence’

None of the three will ever touch anything they cannot analyze or logic they do not understand. Jumping into stocks that are surging due to social media hype or products with mechanisms you don’t understand just because you ‘don’t want to miss out’ is the exact opposite of their philosophy.

2. ‘Independent thinking’ that is not swayed by the opinions of others

They share a common stance of being cautious when the masses are frantically buying, and calmly looking for opportunities during market crashes when no one else is paying attention. If you act the same as the majority, you will neither be able to outperform the market average nor protect yourself from market crashes.

3. Risk management (survival) is the top priority

The most important thing in the world of investing is not ‘winning big,’ but ‘not being forced out of the game.’ Buffett keeps a large amount of surplus cash on hand, Soros closes his positions immediately if he realizes he has made a mistake, and Rogers moves only after confirming historical cycles and supply and demand.

Instead of viewing these ‘investment geniuses’ merely as historical figures, try applying their discipline and their approach to failure to your own accumulation investments and asset management.
