1. The Little Book of Common Sense Investing — John C. Bogle (2007)

Overview

John Bogle — founder of Vanguard and the pioneer of index funds — wrote this concise manifesto to argue that low-cost index investing beats active management over the long run. It’s part philosophy, part practical playbook.

Chapter highlights (condensed)

• Why indexing works: Explains the arithmetic of fees and net performance.
• The cost of active management: Demonstrates how fees, turnover, and taxes erode returns.
• Practical allocation advice: Simple index allocation guidelines for balanced portfolios.
• Behavioral reminders: Why patience and low turnover are investor superpowers.

Key lessons to apply

1. Minimize costs: Fees are the single biggest long-term performance killer. Prefer index funds and ETFs with low expense ratios.
2. Compounding patience: Long-term holding beats frequent trading.

Who should read it?

• Beginners and long-term investors seeking a low-maintenance, high-probability approach.
