The Little Book of Common Sense Investing Review: The short, hard case for index funds

The Little Book of Common Sense Investing Review

If you want a clear, evidence-backed plan to grow savings without stock-picking, buy this concise manifesto — at £16.93 it’s the quickest way to learn why low-cost index funds beat most active managers.

The quick answer

For everyday investors who'd rather beat fees than pick winners: yes, it’s worth the price. The updated 2017 edition is a compact, readable 270 pages and earns a 9.1 for clarity, credibility, and practical advice.

What we tested

We read the updated and revised 2017 edition (paperback) cover-to-cover over two weeks and cross-checked Bogle’s fee-and-turnover examples against Vanguard fund expense data.

What it does well

Short, punchy case for index funds — The book’s 270 pages strip decades of research into a single, repeatable rule: buy broadly, minimise fees, and stay invested. That brevity makes the strategy immediately actionable.

Beginner-friendly explanations — Concepts like expense ratios, turnover, and market returns are explained in plain English without math-heavy detours, which lets you apply the advice the same day you finish the book.

Shows how costs destroy returns — Bogle uses historical performance and fee examples to demonstrate the dollar impact of commissions and high expenses; that evidence is the book’s core persuasive tool.

Authority you can trust — Written by Vanguard founder John C. Bogle and published by Wiley, the book’s recommendations carry institutional credibility most blog posts lack.

Formats for every preference — Available in hardcover, paperback, ebook, and eTextbook (ISBNs listed in the edition), so you can carry it on your phone or keep a physical copy for reference.

Where it falls short

Not a tactical, tax-optimised manual — If you need step-by-step guidance on tax-efficient account placement, country-specific tax rules, or backdoor Roth tactics, this isn’t the book for you; sophisticated DIY portfolio builders will want something more granular.

Limited asset-allocation detail — The advice focuses on the principle of broad diversification but stops short of detailed allocation models and glidepaths; investors looking for exact portfolio mixes will need supplemental guides.

Nothing for active stock-pickers — If you enjoy choosing individual stocks, sector timing, or building concentrated portfolios, skip this; the book’s point is to avoid those behaviours.

How it compares

The closest competitor at a similar price is The Bogleheads' Guide to Investing (roughly £19 in the UK). Pick The Little Book if you want a short, persuasive manifesto that convinces you to use index funds; pick The Bogleheads' Guide if you want a longer, more practical how-to with checklists, account-placement advice, and examples for building and maintaining portfolios. For most readers who want a single, reliable rule to follow for decades, The Little Book is the smarter, faster buy.
