Avoid Hot Stocks

🌱 Beginner★★★★★

The most dangerous stocks are popular ones in trendy industries where everyone is already invested.

💬

Avoid hot stocks in hot industries.

— *One Up On Wall Street*，1989

🏠 Everyday Analogy

Just like queuing up for trendy bubble tea, the higher the popularity, the more expensive it gets. By the time you finally buy it, the hype has already faded. It’s better to choose those time-honored brands with great flavor but no queues—they’re both affordable and reliable.

📖 Core Interpretation

Popular stocks are often overvalued and subject to intense competition.
💎 Key Insight：Hot stocks carry a double risk: overvaluation and competition. When an industry is hot, dozens of companies rush in, margins compress, and most fail. Meanwhile, investor enthusiasm pushes valuations to levels where even the winners cannot deliver satisfactory returns. Lynch found his best stocks in boring, ignored industries. By the time a stock is hot, the easy money has already been made.

❓ Why It Matters

🎯 How to Practice

🎙️ Master's Voice

Owning stocks is like having children—don't get involved with more than you can handle.
Lynch limited his active positions to what he could follow closely. Too many stocks meant too little attention to each.
