Index Funds

🌱 Beginner★★★★★

Index funds offer the best risk-adjusted returns for investors who cannot dedicate time to individual stock analysis.

💬

An index fund is the best choice for the investor who cannot or does not want to devote time to security selection.

— _The Intelligent Investor_，1949

🏠 Everyday Analogy

Just like buying a mixed nuts gift box at the supermarket instead of picking walnuts, almonds, and cashews one by one. Index funds allow you to purchase high-quality stocks across the entire market in one go, saving you the trouble of selection while ensuring balanced "nutrition." The overall quality won’t be compromised by the spoilage of any single type of nut.

📖 Core Interpretation

For investors who do not wish to spend time selecting individual stocks, index funds are the optimal choice.
💎 Key Insight：Graham endorsed index investing before it became mainstream. Most active managers underperform the index after fees over time. For investors without the skill, temperament, or time for security analysis, a low-cost index fund delivers market returns with minimal effort and maximum diversification.
