Warren Buffett Strategy: 7 Principles for Singapore Investors

Last updated: June 2026 | SeaMoneyTips

Who Is Warren Buffett?

Warren Buffett, often called the “Oracle of Omaha,” is one of the most successful investors in history. As chairman and CEO of Berkshire Hathaway, Buffett has delivered an average annual return of approximately 20% over more than five decades – a track record that turned a $10,000 investment in Berkshire in 1965 into over $300 million today.

But Buffett is not just a billionaire investor. He is also a teacher. Through his annual shareholder letters, interviews, and public talks, he has shared his warren buffett investment strategy with millions of everyday investors around the world – including right here in Singapore.

This guide breaks down Warren Buffett’s investment strategy into clear, actionable principles. More importantly, it shows you how to apply these principles as a Singapore investor – whether you are buying SGX stocks, REITs, or global ETFs through your brokerage account.

What Is Warren Buffett’s Investment Strategy? The Core Philosophy

At its heart, Warren Buffett’s investment strategy is value investing – a framework he learned from his mentor Benjamin Graham at Columbia University. The core idea is simple but powerful: buy stocks that are trading below their intrinsic value, and hold them for the long term.

Buffett famously described his approach as buying “wonderful companies at fair prices” rather than “fair companies at wonderful prices.” Unlike traders who try to time the market or chase short-term gains, Buffett invests in businesses he understands, with strong competitive advantages, excellent management, and predictable earnings.

His investment strategy rests on a few timeless principles that have worked across market cycles, economic crises, and technological disruptions. Let us break them down one by one.

Warren Buffett’s 7 Key Investment Principles

1. Margin of Safety – Buy Below Intrinsic Value

The margin of safety is Buffett’s most important rule. It means buying a stock only when its market price is significantly below what you calculate as its true or intrinsic value. If you estimate a company is worth $100 per share, you only buy when it trades at $60 or $70 – giving you a 30-40% cushion against errors in your analysis or unexpected bad news.

For Singapore investors, this principle applies directly. When you analyze a stock like DBS Bank or a blue-chip REIT like CapitaLand Integrated Commercial Trust, do not buy just because it is a household name. Calculate what you think it is worth first. Only pull the trigger when there is a meaningful gap between price and value.

2. Circle of Competence – Invest in What You Understand

Buffett only invests in businesses he truly understands. He calls this staying within your “circle of competence.” If you cannot explain how a company makes money in one or two sentences, do not invest in it. This discipline kept Buffett out of the dot-com bubble of the late 1990s – a decision that was criticized at the time but proven wise when the bubble burst.

As a Singapore investor, your circle of competence might include local banks like DBS, OCBC, and UOB, or REITs that own the malls and offices you visit every day. You might also understand the telecom sector through Singtel or the aviation industry through SIA. Start with what you know, and expand your circle over time through study and research.

3. Look for Economic Moats – Durable Competitive Advantages

An economic moat is a sustainable competitive advantage that protects a business from competitors – just like a moat protected a medieval castle. Buffett looks for companies with strong moats: powerful brands that can raise prices (like Coca-Cola), network effects where each new user adds value (like Visa or Mastercard), high switching costs (like enterprise software), or cost advantages that rivals cannot replicate.

In the Singapore market, you can find economic moats in companies like SingExchange (SGX itself), which benefits from a regulatory monopoly on securities trading in Singapore, or in a REIT like Mapletree Logistics Trust that owns irreplaceable logistics properties across Asia. Identify the moat before you invest – without it, competitors will eventually erode the company’s profits.

4. Focus on Long-Term Value, Not Market Fluctuations

Buffett famously said that the stock market is a device for transferring money from the impatient to the patient. He ignores daily price movements and focuses on the underlying business performance. His ideal holding period is “forever.”

This is especially important for Singapore investors who might check stock prices on their phone every few hours. Short-term volatility is noise. If you own a quality REIT with good management and growing rental income, a 5% price drop in one week does not change the value of the properties it owns. Stay focused on the business fundamentals, not the ticker price.

5. Management Quality – Invest with Trustworthy Leaders

Buffett places enormous weight on the quality and integrity of a company’s management team. He wants leaders who are honest, capable, and think like owners rather than employees looking for their next bonus. He reads annual reports carefully to gauge whether management is candid about mistakes and realistic about future prospects.

When researching Singapore-listed companies, read the CEO letter in the annual report. Does the management blame external factors for every problem, or do they take responsibility? Do they communicate clearly with shareholders? For REITs, look at the track record of the REIT manager in allocating capital and managing the property portfolio over multiple years.

6. Concentration Over Diversification

Buffett has said that diversification is “protection against ignorance.” If you truly understand a business and have high conviction in its future, there is no reason to spread your money across 50 stocks just to reduce risk. He recommends putting meaningful capital into your best ideas.

For most Singapore investors, this principle requires a balanced approach. While you may not want to put everything into one stock, owning 8-15 carefully researched positions is usually better than a scattered portfolio of 50 names you barely understand. Quality over quantity applies as much to your stock portfolio as it does to everything else in life.

7. Be Fearful When Others Are Greedy, and Greedy When Others Are Fearful

This is perhaps Buffett’s most famous quote. When the market is euphoric and everyone is buying, be cautious. When panic sets in and stocks are crashing, that is when the best bargains appear. During the 2008 financial crisis, Buffett invested billions in Goldman Sachs and General Electric – moves that generated huge returns once the market recovered.

The COVID-19 crash of March 2020 was another example. Singapore stocks like the STI ETF dropped over 30% in weeks. Investors who bought during that panic – when others were fearful – were rewarded handsomely as markets recovered over the following months. The next market downturn will create similar opportunities for disciplined investors.

How Warren Buffett Picks Stocks – His Checklist

Buffett does not use complex algorithms or trading software. He uses a simple but rigorous mental checklist. Here are the key factors he evaluates:

Quantitative Factors (the numbers):

• Consistent Earnings Growth – Look for companies that have grown earnings per share (EPS) at a steady rate for 5-10 years, not one-off spikes.
• High Return on Equity (ROE) – Buffett prefers ROE above 15% consistently over multiple years. It shows the company generates strong profits from shareholder capital.
• Low Debt Levels – A company should be able to pay off all its long-term debt with 3-4 years of earnings. High debt makes a company vulnerable in a downturn.
• Good Profit Margins – Buffett likes companies with gross margins above 40% and net margins above 15%. Strong margins indicate pricing power and operational efficiency.
• Owner Earnings – Buffett calculates “owner earnings” (operating cash flow minus maintenance capex) rather than relying on reported net income. This gives a truer picture of the cash the business actually generates.

Qualitative Factors (the story):

• Simple Business Model – If you need a PhD to understand the business, Buffett skips it. The best businesses are often the simplest.
• Brand Power and Customer Loyalty – Can the company raise prices without losing customers? That is a sign of a strong brand moat.
• Recurring Revenue – Does the company sell products customers need to buy repeatedly, or is it a one-time purchase? Subscription models and consumables are more predictable.
• Aligned Management – Does the CEO own significant shares? Is management compensation tied to long-term performance? Skin in the game matters.

Buffett’s 90/10 Portfolio Strategy – His Advice for Everyday Investors

In his 2013 annual letter to Berkshire shareholders, Buffett revealed the investment instructions he left for his wife’s inheritance: put 90% into a low-cost S&P 500 index fund and 10% into short-term government bonds. This is his recommended strategy for most people who do not have the time or expertise to pick individual stocks.

Why does one of the greatest stock pickers of all time recommend index funds? Because Buffett understands that most investors – including professionals – cannot beat the market consistently over long periods. The S&P 500 has returned about 10% annually on average over the last century. By simply buying and holding a low-cost index fund, you capture that return without paying high fees, without making emotional mistakes, and without spending hours researching individual stocks.

Singapore Equivalent of the 90/10 Portfolio:

• 90% – STI ETF (ES3 or G3B) or a global ETF like VWRA (Vanguard FTSE All-World) or CSPX (iShares Core S&P 500) listed on the London Stock Exchange for tax efficiency.
• 10% – Singapore Savings Bonds (SSB) or T-bills – both offer competitive interest rates, are backed by the Singapore government, and have zero default risk.

This simple two-asset portfolio is incredibly effective. Combine this with dollar cost averaging – investing a fixed amount every month regardless of market conditions – and you have a Buffett-approved approach that works for any Singapore investor.

You get global diversification through the ETF, and a safe cash buffer through Singapore government bonds. Rebalance once a year and let compounding do the rest.

How to Apply Warren Buffett’s Strategy in Singapore

Singapore Stocks That Fit Buffett’s Criteria

Let us apply Buffett’s checklist to a few well-known Singapore companies. These are not buy recommendations – they are examples of how to think like Buffett when evaluating SGX stocks.

DBS Group – Singapore’s largest bank has delivered consistent ROE above 12% for years, has a strong deposit base (low-cost funding), a dominant position in Singapore and growing presence across Asia, and a management team widely respected for capital allocation. Its digital banking investments position it well for the future. Key Buffett boxes ticked: consistent earnings, strong moat (regulatory and scale), aligned management.

Sheng Siong Group – This supermarket chain is exactly the kind of simple, understandable business Buffett loves. It sells everyday groceries – a recurring, non-discretionary purchase. It has a cost advantage over competitors through efficient operations, negative cash conversion cycle (it collects cash from customers before paying suppliers), and consistent revenue growth. High ROE, zero debt, simple business model – classic Buffett characteristics.

Using Buffett Principles to Pick Singapore REITs

Singapore REITs (S-REITs) are a unique asset class that fits well with Buffett’s framework. Here is how to apply his principles:

Margin of Safety in REITs: Look at Price-to-Book (P/B) ratio. When a REIT trades below its net asset value (NAV), you are buying the underlying properties at a discount. As of mid-2026, several Singapore REITs trade below NAV, offering a potential margin of safety.

Moat in REITs: The moat comes from the quality and location of the properties. A REIT that owns prime Orchard Road retail space or Grade A CBD office buildings has a moat that a REIT owning suburban industrial properties may not. Irreplaceable locations are a powerful competitive advantage.

Management Quality: Look at the REIT manager’s track record in acquiring properties at good prices, managing occupancy rates, and controlling costs. Compare Distribution Per Unit (DPU) growth over 5+ years – consistent growth signals capable management.

Debt Levels: Check the aggregate leverage ratio. Singapore regulations cap S-REIT leverage at 45-50%, but the best-managed REITs stay well below that limit. High leverage means higher risk when interest rates rise. For Singapore investors planning for retirement, combining REIT income with CPF LIFE payouts can create a reliable retirement income stream.

Value Investing Through CPFIS and SRS

Singapore investors have two powerful tax-advantaged accounts that can be used for Buffett-style investing: the CPF Investment Scheme (CPFIS) and the Supplementary Retirement Scheme (SRS).

CPFIS: You can invest your CPF Ordinary Account (OA) savings above $20,000 in a range of approved investments including stocks, ETFs, and REITs listed on SGX. The key advantage is that CPF OA earns a guaranteed 2.5% interest, so your hurdle rate is low – any long-term return above 2.5% is a win. Use CPFIS for the “forever” part of your Buffett-style portfolio: blue-chip Singapore stocks and STI ETF that you intend to hold for decades.

SRS: Contributions to your SRS account are tax-deductible (up to $15,300 for Singapore citizens), and investment gains grow tax-free until withdrawal. You can invest SRS funds in stocks, ETFs, REITs, and bonds through any SRS-approved bank (DBS, OCBC, UOB). This makes SRS ideal for a Buffett-style buy-and-hold strategy since you are not paying taxes on dividends or capital gains along the way.

Tools and Resources for Buffett-Style Investing in Singapore

Stock Screeners: To find Singapore stocks that meet Buffett’s criteria, use screeners like SGX Stock Screener (free on sgx.com), Investing.com stock screener for SGX, or paid services like ShareInvestor. Set filters for ROE above 15%, debt-to-equity below 0.5, and consistent earnings growth.

Brokerages for Long-Term Investors: For a Buffett-style buy-and-hold approach in Singapore, consider these platforms:

• Interactive Brokers (IBKR SG) – Lowest commissions for both SGX and global markets, ideal for buying and holding ETFs like CSPX or VWRA
• Tiger Brokers / Moomoo – User-friendly platforms with low fees, good for Singapore and US market access
• DBS Vickers – Integrated with DBS accounts, good for CPFIS and SRS investing through DBS

Essential Reading: Buffett’s annual shareholder letters (available free at berkshirehathaway.com), “The Intelligent Investor” by Benjamin Graham (Buffett’s mentor), and “The Essays of Warren Buffett” by Lawrence Cunningham. These are better investments of your time than any stock-picking course.

Common Mistakes When Trying to Invest Like Warren Buffett

Mistake 1: Blindly Copying Berkshire’s Portfolio. Every quarter, Berkshire Hathaway publishes its 13F filing showing its stock holdings. Many retail investors immediately copy those positions. But you are buying months after Buffett bought, often at higher prices, and without his full context. You also do not know which positions he might be selling at that very moment. By the time you see his portfolio, the opportunity may have passed.

Mistake 2: Ignoring Position Sizing and Portfolio Context. When Buffett buys a stock, it may represent 1-2% of Berkshire’s massive portfolio. When you buy the same stock with your S$10,000 portfolio at 20% allocation, your risk profile is completely different. Always size your positions based on your own portfolio and risk tolerance.

Mistake 3: Overpaying for Quality. Even the best company in the world can be a bad investment if you pay too much for it. Many investors hear “buy wonderful companies” and ignore the “at fair prices” part. A good company trading at 50 times earnings is unlikely to deliver good long-term returns regardless of how wonderful the business is.

Mistake 4: Selling During Market Drops. Buffett used the 2008 crisis to buy, while many investors panic-sold. The next time the STI drops 20%, your instinct will tell you to sell and “wait until things calm down.” That instinct is wrong. If you own quality assets, market crashes are buying opportunities, not reasons to exit.

Is Warren Buffett’s Strategy Still Relevant in 2026?

Some critics argue that Buffett’s value investing approach is outdated. They point to the rise of technology stocks that trade at high multiples, the speed of information in the digital age (making mispriced stocks harder to find), and the growth of passive investing. Are they right?

The short answer is no. The principles of value investing – buying assets below their intrinsic worth, demanding a margin of safety, and thinking long-term – are timeless. What has changed is the toolkit. Today, intangible assets like data, network effects, and brand ecosystems are as important as physical factories and real estate. Buffett himself adapted by investing heavily in Apple starting in 2016 – a company he once avoided as “too tech.” He recognized that Apple’s ecosystem and brand loyalty created an economic moat as powerful as any traditional business.

For Singapore investors in 2026, Buffett’s principles are arguably more relevant than ever. In a world of meme stocks, cryptocurrency speculation, and TikTok investment “gurus,” the discipline to buy quality assets at reasonable prices and hold them for years is a genuine competitive advantage. The market rewards patience, and patience remains in short supply.
