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

1. Asset allocation is more important than stock picking 🎯

• Citing multiple studies, Gibson argues that more than 90% of portfolio performance is determined by asset allocation , not stock picking or market timing.
• Instead of spending time picking stocks, focus on how to diversify your money across different asset classes.

2. Diversified asset classes 📊

The book provides an in-depth analysis of the following key assets:

• Stocks (U.S. and International) : High risk, high reward, source of long-term value growth.
• Bonds : Stable returns, low volatility, and balanced stock market risks.
• Real estate and REITs : provide a different source of return than stocks and bonds.
• Cash and short-term instruments : High liquidity, but low long-term returns.

3. The power of decentralization 🌍

• When the correlation between different assets is low, it can effectively reduce the volatility of the investment portfolio.
• For example: Bonds often provide a buffer when the stock market falls.
• Gibson uses a large amount of historical data to demonstrate that cross-asset diversification can significantly improve "risk-adjusted returns."

4. Efficient Frontier

• The book applies Modern Portfolio Theory (MPT) to show how to find the optimal balance between risk and return.
• The "efficient front" is a curve that represents the optimal investment portfolio, and investors should choose a position on this curve that suits their risk tolerance.

5. The importance of rebalancing 🔄

• Even if an ideal configuration is designed, the proportions will shift as the market changes.
• Regular rebalancing (e.g. annually) can help maintain risk levels and avoid portfolio imbalance.

6. Investors’ psychological challenges

• Most investors will panic sell when the market falls sharply, or chase highs when the market rises sharply.
• Gibson emphasized that discipline and patience are more important than intelligence .
• The value of asset allocation lies in allowing investors to "sleep well" and avoid emotional operations.

7. Long-term perspective ⏳

• The short-term market is difficult to predict, but in the long run, diversified allocation can provide stable returns.
• Investing should be a "marathon" rather than a "sprint".
