The Little Book of Common Sense Investing: The Only Way to Guarantee Your Fair Share of Stock Market Returns
v1.0.0John C. Bogle's "The Little Book of Common Sense Investing" — an executable toolkit for understanding why low-cost index funds are the only way to guarantee your fair share of stock market returns, and why the relentless rules of humble arithmetic make active investing a loser's game. Covers 7 use cases: ① Index Fund Basics — why owning the whole market beats picking stocks ("Why do index funds outperform most active funds?") ② The Cost Problem — how fees destroy wealth ("How much am I actually paying in fees?") ③ The Gotrocks Parable — understanding the Helper problem ("Who is taking my money and how do I stop it?") ④ Reversion to the Mean — why past performance is a trap ("Why did my fund stop outperforming?") ⑤ Asset Allocation — stocks vs bonds by age ("How should I split my portfolio between stocks and bonds?") ⑥ Tax Efficiency — minimizing what the government takes ("How do I pay less in investment taxes?") ⑦ Building a Portfolio — the three-fund solution ("What's the simplest portfolio that actually works?")
