Warren Buffett, the legendary investor and CEO of Berkshire Hathaway, is known for his simple yet powerful investment principles. His success is due to a long-term vision, disciplined decision-making, and a deep understanding of companies and markets. After 80 years of investing, it earned him a place in the top 10 richest Americans. In this article, we list ten important Warren Buffett stock market wisdom that every investor should know. Of course, Value Square also uses these in the management of its funds.
Buffett sees investing not as buying stocks, but as acquiring part of a company. This means that you have to analyse a company as if you were buying the entire company. Look at the fundamentals, such as profitability, management quality and competitiveness, and don't be guided by short-term price fluctuations. A company with a strong brand, loyal customers and a proven business model will usually be more successful in the long term than companies that only focus on rapid growth without a solid basis.
Buffett stresses the importance of counterintuitive thinking: “Be anxious when others are greedy, and be greedy when others are anxious.” This means buying when the market is pessimistic and selling when the market is overly optimistic. Major crises often offer the best buying opportunities. During the 2008 financial crisis, for example, Buffett invested billions in companies like Goldman Sachs and Bank of America because he knew that these banks would recover in the long term.
Buffett would rather choose a great company at a reasonable price than a mediocre company at a low price. Although in his early years he was more focused on buying undervalued companies, he later realized that quality is more important than a low valuation in the long run. He compares this to buying a fantastic home at a fair price instead of buying a dilapidated house at a bargain price.
Buffett is a staunch believer in long-term investing. He believes that time is an investor's most powerful ally.” The stock market is a mechanism for transferring money from the impatient speculator to the patient investor.” This means that you should not try to time the market, but stick to quality investments for the long term. The magic of compound growth plays a major role here: the longer your investments pay off, the greater the final return.
Buffett prefers companies with an “economic moat” — a sustainable competitive advantage that peers find difficult to overcome. This can be due to, for example, brand strength, economies of scale or patents, or high switching costs for customers. Companies with a strong economic moat are more resistant to competition and economic setbacks. Think about companies like Coca-Cola and Apple, which have strong brands and loyal customers who don't easily switch to competitors.
Buffett not only looks at a company's financial figures, but also at the people who run it. He is looking for companies with honest, capable and visionary managers. But the integrity and shareholder orientation of management are especially crucial. He himself summarizes it with a typical one-liner: “You can't do good business with bad people”.
He avoids companies with a high turnover of employees in the management, and CEOs who pay themselves generous bonuses or option packages. He prefers to buy companies from entrepreneurs who invested money in the company themselves, or set up the company with their own money: they often have the best attitude to deal with the co-investors' money.
It should come as no surprise that investing in companies with a family or strong reference shareholder is also one of the cornerstones of Value Square's investment strategy.
Stock market hypes are dangerous because they tempt investors to make irrational decisions based on mass psychology rather than fundamental analysis. When a certain new technology comes on the scene, a particular stock, sector, or asset class can suddenly become popular at lightning speed due to excessive optimism. The price may rise far above its actual value.
This is a recurring phenomenon in financial history. Just think of the tulip bulb mania, the bicycle manufacturer hype of 1890, the radio boom of 1920 or the bowling bubble of 1950, where bowling centers were driven to crazy ratings.
Companies often trade at excessive valuations with minimal profits or even without a clear business model, simply because they see themselves as representing the future but overestimating it. This leads to the illusion that prices keep rising endlessly, but as soon as sentiment changes, a painful correction follows.
Hypes are reinforced by media attention, social pressure and the urge not to miss out on opportunities, so inexperienced investors are often at the pinnacle. At the time of writing, we are seeing the AI hype on the US stock markets partially deflate, while Europe is overly enthusiastic about demand for defense stocks.
However, hypes don't usually arise on things that have no value. In most cases, a few winners do emerge (just think of Amazon from the internet bubble, Dunlop from the bike bubble or Lucky Strike EC from the bowling era). But they do drive the price far beyond its intrinsic value and underestimate the effect of increasing competition on many of the emerging players. As a result, most of the hyped companies eventually disappear, leaving investors/speculators destitute.
A strong balance sheet is essential to a company's financial health and determines how well it can withstand economic shocks. Companies with a lot of debt and low cash reserves are at higher risk of financial problems, especially when interest rates rise or profits come under pressure. During the life of a company (or a person), this happens due to circumstances inside or outside of one's own will. A solid balance sheet means that a company has sufficient equity, generates stable cash flows and is not dependent on finding additional funding to survive. Important factors to analyse include the ratio between debt and profit, the interest coverage ratio and the amount of cash.
Too much debt can lead to the forced sale of assets or bankruptcy, while a healthy balance sheet offers financial flexibility to invest and bridge crises. There are many examples. Dexia and ING lost their asset management branch (now Candriam and NN). Umicore had to sell its mines. Vivendi had to divest the utilities sector after debt-financed purchases in the media sector. General Electric, once the best-known American conglomerate, is a shadow of its former self.
Limited debt purchases support growth, but too much can seriously damage financial health.
Profit can be manipulated by accounting tricks, but cash flow doesn't lie. A company can look profitable on paper when it actually has trouble paying the bills.
This is because the profit and loss account is subject to depreciation, tax benefits and other items that have no direct impact on liquidity. Cash flow, on the other hand, shows how much money is actually coming in and is used in daily operations.
A strong cash flow means that a company is able to pay off debt, pay dividends, buy back its own shares, and invest without relying on external funding.
Companies with weak cash flow, on the other hand, often have to issue new stocks or get into debt to survive, at the expense of shareholders. By focusing on cash flows instead of accounting profits, you avoid companies that are profitable on paper but are actually financially shaky.
A good example is Unibail-Rodamco-Westfield (URW), the French real estate giant. URW can show high paper profits through accounting revaluations, while actual cash flows are under pressure due to rising financing costs, constant investments and vacancy
Even Buffett makes mistakes, but he learns from them. He stresses the importance of continuous education and reflection: “The best thing you can do is to continuously train yourself.” This means reading annual reports, financial books and studying successful and failed investments. Buffett reads hundreds of pages a day and sees reading as the most important factor in his success.
Warren Buffett's stock market laws are timeless and applicable to every investor, from beginner to expert. By applying these principles, you can significantly increase your chances of a successful investment career. Investing isn't a sprint, it's a marathon.
