What is four m's?
The four M's are a stock-picking checklist used by value investors to judge a company before buying. They stand for meaning, moat, management, and margin of safety. Warren Buffett's rule don't lose money guides the whole process.
You use the four M's to avoid bad buys. Each M forces you to ask a hard question. If you can't answer all four, you walk away. That discipline keeps your capital safe.
The Meaning of Each M
The first M is meaning. You must understand what the company does and why it exists. If you can't explain its purpose in one sentence, skip it. You need a business you can grasp.
The second M is moat. A moat is a durable competitive advantage. Think of a brand, patent, or network that keeps rivals out. Without a moat, profits get competed away fast.
The third M is management. You need honest, capable leaders who think like owners. Check their track record and how they allocate cash. Bad management can destroy a good business.
The fourth M is margin of safety. You buy only when the price is well below your estimate of value. That gap protects you from mistakes and bad luck. It's your cushion.
