📚 Common Sense About Mutual Funds — John C. Bogle's detailed introduction

Today, I'd like to introduce a landmark book in investment history : Common Sense on Mutual Funds: New Imperatives for the Intelligent Investor . Its author is none other than John C. Bogle, the founder of Vanguard Group and known as the "Father of Index Funds."

Originally published in 1999 , this book was revised after the 2009 financial crisis to address market changes. It is considered one of the most authoritative classics on mutual funds and long-term investing , and has had a profound impact on investors, financial advisors, and academia worldwide.

The core idea is simple but powerful: most actively managed mutual funds can't beat the market over the long term, and high fees erode returns. The smartest bet is a low-cost, diversified, long-term index fund.

📖 Book Core Concept

💡 Investing should be based on "common sense"

Wall Street often complicates investing, leading people to mistakenly believe that professional investment management is required to have a chance of success.
Bogle believes that the essence of investing is actually very simple - sharing in the long-term growth of companies and the economy.
Investors should avoid short-term speculation and focus on long-term holding and reducing costs.

👉 Editor's take: This book is like a lamp that breaks through the fog of finance, allowing people to see what real investment is.

🎯 Why do most mutual funds fail?

1. High fees : Management fees, handling fees, and transaction costs will eat into most of your returns over time.
2. Overtrading : Fund managers frequently buy and sell, which leads to higher costs and greater risk of mistakes.
3. Chasing short-term performance : Many funds chase hot stocks to attract investors, but long-term returns are unstable.
4. Market efficiency : The market already reflects most of the information, making it extremely difficult for professional managers to beat the market in the long run.

👉 Editor's comment: These problems are exactly why Bogle launched the "index fund".

📌 Important points in the book

1️⃣ Cost is the biggest enemy of return on investment💣

Investment return = market return − costs. Costs include management fees, transaction fees, and marketing expenses. The only thing ordinary investors can control is to choose low-cost tools.

👉 Editor’s take: This sentence has almost become the core of Bogle’s investment philosophy.

2️⃣ Long-term investment vs. short-term speculation⏳

Investing = Sharing in a company's long-term growth. Speculating = Trying to predict market fluctuations. Short-term fluctuations are uncontrollable, but long-term trends are reliable.

👉 Editor's comment: This reminds us "not to watch the market every day, but to focus on the next 20 years."

3️⃣ The power of index funds 🏆

Index funds have extremely low fees and track the overall market performance over the long term, outperforming most active funds. They are "the most extraordinary tool for ordinary investors."

👉 Editor’s take: Index funds are the most powerful weapon of the “lazy investing method.”

4️⃣ Investor’s psychological trap🧠

• Overconfidence: Believing you can pick the right fund or stock
• Chasing performance: often buying high and selling low
• Panic and Greed: Dancing with Market Sentiment
  Bogle emphasizes: Discipline and patience are the keys to victory

5️⃣ Investment Portfolio and Asset Allocation📊

Diversification is key to reducing risk. Build a balanced portfolio of stocks and bonds, adjusting it based on age and risk tolerance. Keep it simple and avoid over-diversifying into complex funds.

👉 Editor’s take: Asset allocation may sound old-fashioned, but it’s the foundation of successful investing.

5. Investment Psychology and Discipline: Avoiding Human Weaknesses

👉 Editor's opinion: This book contains both theory and practice, and has a complete structure. After reading it, you will be able to establish a complete investment perspective.

💡 Inspiration from the book

For individuals

Don't chase short-term performance, focus on long-term costs to determine your ultimate wealth gap. Discipline and patience are more important than talent.

For families

Family finance should focus on low-cost index funds. Parents should teach their children that investing is about sharing in economic growth, not gambling.

To society

Bogle's philosophy promotes the "democratization of investing," freeing ordinary people from being exploited by high-fee funds. By encouraging more people to adopt low-cost investing, he can reduce retirement poverty and financial anxiety.

👉 Editor's Thoughts: Bogle didn't just change the investment industry; he actually changed the financial destiny of society as a whole.
