📚《The Four Pillars of Investing》—William J. Bernstein

Hello fellow investors! Today, I'd like to introduce a seminal work, "The Four Pillars of Investing: Lessons for Building a Winning Portfolio, " considered a "must-read financial classic" in the investment world. The author is William J. Bernstein , a neuroscientist-turned-investment researcher.

First published in 2002 and updated in 2023, this book is widely hailed as one of the best books for helping retail investors understand the essence of investing. Compared to his earlier work, The Intelligent Asset Allocator, this book is more comprehensive and practical, breaking down investing into four key areas, allowing readers to develop a comprehensive investment perspective from different perspectives.

🌟 Author Background: Who is William J. Bernstein?

• Medical background : Originally a clinical neuroscientist, not a professional financial background.
• Self-taught investment expert : Because of his interest in financial freedom, he studied financial history, asset allocation and market behavior in depth.
• Investment writer : Author of several classics, including "The Intelligent Asset Allocator" and "The Investor's Manifesto".
• Features : The difficult financial theories are written in a simple and clear way so that ordinary people can understand them.

📖 The meaning of the title

“ The Four Pillars of Investing” literally means “the four pillars of investment” .
👉 Bernstein believes that successful investing is not just about skills, but about mastering four aspects simultaneously:

1. Investment Theory
2. Investment History
3. Investing Psychology
4. Investing in Business

These four pillars constitute a complete investment knowledge system.

🔑 Core content of the book (edited by the editor)

1. The First Pillar: Investment Theory 📊

• Explain the relationship between risk and return based on Modern Portfolio Theory (MPT).
• Emphasize the importance of diversification and reduce volatility through different assets.
• Explain the source of "risk premium": Investment returns come from taking risks, not luck.
• Core concept: Asset allocation is more important than stock picking .

2. Second Pillar: Investment History📜

• Lead readers to review the market history of the past few hundred years.
• How assets like stocks, bonds, gold, etc. perform over time.
• Examples of financial bubbles and crashes (e.g., the Great Depression, the dot-com bubble).
• Core revelation: Although the market fluctuates, the long-term trend is upward.

3. The third pillar: investment psychology

• Investors are emotional creatures, constantly swinging between fear and greed.
• Biases in behavioral finance: overconfidence, herding, and loss aversion.
• The key to successful investing is not to find a "smart method", but to control your own mentality.
• Core reminder: The biggest enemy is not the market, but yourself .

4. The fourth pillar: Investing in business

• The business of Wall Street is to make money from investors, not to help investors make money.
• Active funds have high fees and unstable performance, and most cannot outperform the market in the long run.
• The financial industry earns fees through complexity and marketing, and retail investors should avoid falling into the trap.
• Core advice: Low-cost index funds are the best tools for retail investors .

🌱 Investment advice in the book

• Build a diversified investment portfolio (stocks, bonds, international markets).
• Use low-cost index funds or ETFs.
• Avoid trying to predict the market and short-term operations.
• Rebalance regularly to keep asset allocation stable.
• Persevere for a long time and let time and compound interest work their magic.

💡 Editor's opinion: The value of this book

• Comprehensiveness : Covering four major aspects: theory, history, psychology, and business, allowing readers to establish a "panoramic perspective."
• It is both in-depth and readable : it contains rigorous data as well as stories and cases, suitable for people who want to improve their investment literacy.
• Mindset building : Special emphasis is placed on psychological and behavioral biases, which is an aspect that many investment books ignore.

📌 Editor's Summary

The Four Pillars of Investing tells us:
👉 Investing does not rely solely on genius inspiration, but requires the support of four pillars: theory, history, psychology, and business .
