Full summary and key takeaways →The 12 questions
- 1.
O'Shaughnessy's core argument is that mechanical rules beat discretionary judgment in investing. Do you find that convincing, and does it apply to other high-stakes decision domains?
- 2.
The book shows that many popular investment approaches underperform the market over long periods. Why do you think those approaches remain popular if the data against them is available?
- 3.
Back-testing has inherent limitations — survivorship bias, data mining, and the fact that past patterns may not repeat. How much should those limitations reduce your confidence in the conclusions?
- 4.
O'Shaughnessy argues that emotional and behavioral biases are the primary reason investors underperform. What specific biases do you think are most relevant to how you make financial decisions?
- 5.
The price-to-sales finding is counterintuitive for many readers — sales rather than earnings as the best valuation metric. What is the logic, and where do you think it breaks down?
- 6.
Factor investing has become mainstream in the years since this book was published, through 'smart beta' funds and factor ETFs. Does the democratization of factor investing reduce its edge?
- 7.
The book recommends a diversified portfolio of cheap, improving stocks rather than concentrated bets on a few great ideas. Is that approach satisfying intellectually, or does it feel like giving up on understanding individual businesses?
- 8.
O'Shaughnessy is both a researcher and a practitioner who manages money using his own methods. Does that combination increase or decrease your confidence in the research?
- 9.
The fourth edition adds data through the financial crisis of 2008-2009. How did the strategies perform during that period, and what does that tell you about the limits of back-testing?
- 10.
If you were constructing a personal investment approach from this book's findings, what would your portfolio look like?
- 11.
Value strategies have historically underperformed growth strategies for extended periods (the 2010s being the most prominent example). How should long-term investors handle multi-year underperformance of a strategy they believe in?
- 12.
What does O'Shaughnessy's evidence suggest about the value of active fund management, and what are the implications for how you should allocate money to the fund industry?
How to run the discussion
- Pick six to eight, not all of them. An hour of real discussion covers fewer questions than anyone expects, and racing the list is what makes a book club feel like homework.
- Open with what people noticed, not what they concluded. Asking for a verdict first hardens opinions before anyone has heard each other.
- Let the disagreement run. The questions below that split a room are the ones worth the time; the ones everyone answers the same way can be skipped.
- Ask the quiet person a specific question. A direct, narrow question is far easier to answer than an open invitation to contribute.
