Passive Investing & Index Funds

The most counter-intuitive idea in investing is that doing less wins. Decades of evidence show that low-cost, broadly diversified index funds outperform the overwhelming majority of active managers — over five-year windows, ten-year windows, and especially across full market cycles. This book is the playbook for capturing that edge: how indexing works, why it works, the tools that implement it, and the discipline required to leave it alone.

Who this book is for

You're new to investing or you've been picking individual stocks and your results aren't keeping up with the S&P 500. You've heard "just buy an index fund" but want to understand why — the math, the structure, the historical record, and the cases where indexing falls short. You want a portfolio you can hold for thirty years without second-guessing every quarter. This book is for you.

What you walk away with

• The full Bogle story — how a former mutual-fund executive built the world's largest asset manager around the radical idea of charging less and matching the market.
• What an index actually is — the S&P 500, total market, MSCI World, FTSE All-World, and the construction rules that decide what's in and what's out.
• The mechanics of index funds and ETFs — creation/redemption, in-kind transfers, sampling vs full replication, and where tracking error comes from.
• The data on active vs passive — SPIVA scorecards, persistence studies, the survivorship-bias trap, and why "above-average managers" stay above average less often than coin flips would predict.
• A complete tour of costs: expense ratio, transaction costs, bid-ask spreads, tracking error, tax efficiency, and the fee drag that decides multi-decade outcomes.
• The major index providers — S&P Dow Jones, MSCI, FTSE Russell, Bloomberg, CRSP — and how their methodology differences ripple through your portfolio.
• Weighting schemes beyond market-cap: equal-weighted, fundamental-weighted, cap-weighted dividends, and where each makes sense.
• Smart beta and factor investing — value, size, momentum, quality, low-volatility — and a sober look at what the evidence supports vs what's marketing.
• A complete walkthrough of building a 3-fund portfolio (US, international, bonds) including allocation tables, account placement, and rebalancing.
• The All-Weather, Permanent, Boglehead, and Lazy portfolios — what each was designed to survive, and the trade-offs of each.
• Asset allocation glide paths — target-date funds, age-based equity allocation, sequence-of-returns risk, and how to think about decumulation.
• Disciplined rebalancing rules — calendar vs threshold, taxable-account considerations, and the behavioural value of rebalancing beyond the math.
• A clear-eyed catalogue of common passive-investing mistakes — chasing recent winners, abandoning the strategy in drawdowns, layering complexity that doesn't help, and the index-fund traps that catch even disciplined investors.

How to read this book

Chapters 1–4 are foundational and best read in order: Bogle, indexes, index-fund mechanics, ETFs vs mutual funds. Chapter 5 (the data on active vs passive) is the empirical case for the whole approach. Chapters 6–9 build the toolkit (costs, providers, weighting, factors). Chapters 10–13 turn theory into practice (3-fund portfolio, lazy portfolios, glide paths, rebalancing). Chapter 14 (mistakes) is best read after the rest, when you have the framework to recognise the traps. Chapter 15 is the consolidated glossary — keep it open while reading.
