Finding Tenbaggers

🌿 Intermediate★★★★★

Your best investment ideas come from your own daily experience as a consumer and professional.

💬

In my experience, the best stocks to buy are the ones you already know.

— *One Up On Wall Street*，1989

🏠 Everyday Analogy

Just like shopping for groceries at your familiar market, you know which vendor has the freshest produce, which stall owner is the most honest, and what vegetables are in season. The same principle applies to investing: the companies you encounter in your daily life often hold the greatest opportunities, because you can be the first to notice changes in them.

📖 Core Interpretation

Ten-bagger stocks typically emerge from the rapid-growth category, characterized by high growth rates, low valuations, and large market potential.
💎 Key Insight：Lynch found some of his biggest winners — Dunkin' Donuts, Hanes, Taco Bell — by observing what products people loved. By the time Wall Street discovers a great consumer company, the stock has often already doubled. Your advantage as an individual is spotting trends at ground level: the restaurant that always has a line, the product everyone at work uses. Start your research there.
