Thanks to NetGalley for this gifted audio book. All opinions are mine. Now yall, let’s get into the book. Stay Calm by David Booth is a financial advice book that is less about telling you exactly what to invest in and more about getting your head in the right place before you invest. 💰 Booth makes a strong case for practical optimism, patience, discipline, and accepting that uncertainty is simply part of the investing game. I really appreciated the professional stories and personal insights sprinkled throughout because they made the financial concepts feel much more relatable and less like somebody was throwing Wall Street alphabet soup at me. 😁 This is a book that can meet you wherever you are in your investing journey, whether you’re just getting started or you’ve been doing this for years and need a little reminder not to panic when the market gets dramatic. My biggest takeaway was that successful investing isn’t necessarily about having all the answers—it’s about having the right mindset and sticking with a thoughtful, long-term approach. If you’re looking for practical financial wisdom without a bunch of get-rich-quick nonsense, Stay Calm is definitely worth adding to your reading list.

A Theory Has to Make It Through Tuesday
David Booth’s “Stay Calm” is a book about what happens after elegant financial ideas meet payroll, panic, bad timing, human vanity, and the irritating refusal of the future to follow instructions.
By Demetris Papadimitropoulos | August 19th, 2026
David Booth’s most revealing investing story is about a strategy that had the good fortune to be killed. In the early 1970s, at Wells Fargo, Booth and his colleagues built Stagecoach, a leveraged attempt to turn the new science of markets into an investable product. It was clever, overengineered, expensive to run, and difficult to place with clients. Wells Fargo shut it down. Then the 1973–74 bear market arrived. Booth later calculated that Stagecoach might have lost at least three quarters of its value, enough to discredit indexing while indexing was still learning to walk. The plainer capitalization-weighted approach survived. “Stay Calm” spends pages warning against prediction, but this near miss teaches something harder to package: a system earns trust by remaining livable when its cleverest assumptions meet an uncooperative world.
Even the title understates Booth’s argument. The founder of Dimensional Fund Advisors is not chiefly asking readers to become calmer people. He wants them to build fewer situations in which panic gets a vote. Diversify. Plan instead of predict. Preserve options. Know which levers are actually yours. Decline to treat every urgent headline as an instruction. Calm, in Booth’s account, is not the moral prerequisite for good investing. It is one consequence of good design, and of a kind of agency that does not require foresight.
Most personal-finance books inherit their machinery without showing the factory. Booth remembers the factory floor. He arrives at the University of Chicago in 1969 from Kansas, studies under Eugene Fama, encounters the efficient-market hypothesis while its implications still sound subversive, and later helps build some of the earliest index portfolios. What now passes for common sense – benchmarks, broad diversification, suspicion of stock-picking prowess – appears here as the residue of arguments, datasets, computers, failed products, and years spent making theory survive contact with actual money. Booth’s advantage is not that he has discovered a new commandment. It is that he remembers when the old ones were still under construction.
Execution, more than serenity, is Booth’s hidden subject. As a teenager selling shoes in Lawrence, Kansas, he notices how commissions can tempt a salesman to push a pair that does not fit. He nearly does it once, dislikes himself for the minute, and adopts a rule that follows him into finance: do not sell shoes that do not fit. Decades later, the same ethic reappears in his discussions of advisers, incentives, portfolios, and trust. Booth likes simple conclusions, but he is unusually attentive to the engineering underneath them. A shoe has to fit. A portfolio has to fit. A theory has to make it through Tuesday.
The book’s three parts do more than sort the material. Part I, “The Science of Investing,” explains the research revolution Booth inherited and helped implement. Part II, “The Mindset to Stay Calm,” turns toward the person behind the account: flexibility, planning, control, noise. Part III, “True Wealth,” asks what a successful portfolio is supposed to buy besides another successful portfolio. Along the way, Booth changes the meaning of his own vocabulary. Risk becomes something to manage rather than defeat. Compounding migrates from capital to relationships. Wealth eventually means time, choice, generosity, and room to move.
Repetition is how Booth makes the rules portable, and it is also where the book starts to chafe. “Don’t predict, plan.” Control what you can. Preserve flexibility. Tune out the noise. These are distinct instructions, but they occupy neighboring rooms, and Part II walks the corridor more often than it needs to. The chapter-end takeaways and later Investor’s Guide make “Stay Calm” easy to reopen during a market tantrum. They also ensure that no principle leaves the premises without being frisked twice.
If Part I moves fastest, it is because Booth can tell financial history from inside the room. Mac McQuown haunts computer facilities trying to turn quantitative ideas into portfolios. Fama and other academics test assumptions against newly usable data. Booth leaves the doctoral track, joins practitioners, helps create Dimensional in 1981, and learns that research is only one ingredient in a firm. Trading, governance, incentives, client education, and the ability to do tomorrow what you promised yesterday matter just as much. The intellectual romance here is not genius descending from a mountain. It is the less cinematic pleasure of seeing an idea survive payroll.
Part II becomes better when biography stops behaving like a case study. Booth’s mother develops Alzheimer’s; his father has cancer and then dies suddenly after being struck by a car while directing traffic around an accident. After the funeral, Booth and his siblings open their father’s safe-deposit box and find $15,000 in cash. A child of the Depression, his father never entirely trusted banks. Booth understands the stash not as a forecast of catastrophe but as preparation for catastrophe without a name. Few episodes make “don’t predict, plan” feel less like advice and more like inheritance.
And yet the scene matters because it does not promise immunity. Preparation does not prevent cancer, bereavement, crashes, or layoffs. It changes the number of ways surprise can ruin you. In finance, diversification spreads exposure. In life, Booth is sensible enough to admit that the analogy breaks: nobody can diversify across a thousand bodies, spouses, children, or careers. Human beings make concentrated commitments because intimacy itself is concentrated. The useful translation is narrower – build enough savings, skills, relationships, and flexibility that one bad outcome is not automatically the whole outcome.
Plainness is Booth’s chosen register, and it suits him. He favors declarative sentences, direct address, ordinary nouns, and paired distinctions sturdy enough to survive a bad trading day: prediction and planning, signal and noise, control and management, skill and luck. He has little interest in displaying vocabulary for its own sake. The voice is genial, occasionally folksy, intentionally low-friction. One can almost hear the investment philosophy in the sentence design: remove unnecessary motion, keep the costs down, let the durable parts carry the weight.
Art helps explain why Booth trusts that kind of restraint. He loves spare, large-scale work whose apparent simplicity conceals engineering, patience, and exact execution. “Stay Calm” wants a similar effect. Its advice sounds obvious only after a considerable amount of history has been compressed into it. Simplicity here is not ignorance with good branding. It is complexity that has learned which parts can be discarded. Booth is less distinctive when concrete memory gives way to broader language about purpose and progress; as the claims widen, the sentences become more interchangeable.
Don’t mistake the geniality for neutrality. Booth has little patience for stock-picking bravado, market timing, gurus, or the human habit of giving skill all the credit that luck would like to invoice for. The chapter built around Errol Morris and the documentary “Tune Out the Noise” makes that skepticism vivid. Morris once took his success investing in Apple as evidence that diligent research could help him identify exceptional companies. Interviews with Booth’s circle force him to entertain the less flattering possibility that a spectacular result can coexist with an unreliable method. Hindsight, “Stay Calm” reminds us, is an efficient publicist.
Inside that skepticism is the book’s most attractive revision of expertise. Financial culture likes expertise in costume: the hot call, the prescient warning, the analyst who knew before everyone else. Booth offers the drabber version. Expertise may consist of knowing where knowledge stops. “I do not know which company will win” can be a more sophisticated sentence than a twelve-point memo explaining why one surely will. Here Booth sits near Annie Duke’s “Thinking in Bets,” though he reaches uncertainty through public markets rather than poker.
Money, however, is not where Booth wants to leave us. Part III asks what “winning” means once the account has done what it was built to do. A Las Vegas loss can still purchase a cherished evening with a daughter. Philanthropy can return accumulated advantage to schools that formed you. Art can enrich a room without outperforming an index. Time with family requires no benchmark. The question shifts from how efficiently money compounds to what money is eventually allowed to become.
In Part III, compounding starts to behave less like a formula than a family resemblance. Capital compounds, but so do habits, knowledge, relationships, institutions, generosity, reputation, and love. The expansion works best when it gives money an exit route from finance. A portfolio has not completed its work when it merely produces a larger portfolio. It completes its work when capital reappears as time, education, choice, memory, care, or the ability to make somebody else’s future less narrow.
The metaphor also has ambitions beyond its jurisdiction. Markets offer deep datasets, measurable returns, repeated transactions, and literal diversification. Grief does not. Illness does not. Marriage does not. Booth often knows this, and his memoir is strongest when experience refuses to become tidy. Yet almost every hard event is eventually translated into a principle. His father’s death, his mother’s decline, his own cancer – each acquires explanatory labor. Now and then one wishes a sorrow could remain a sorrow for another page before it is asked to teach.
Read against the previous nine chapters, Booth’s optimism creates the book’s most revealing contradiction. His confidence is not foolish: he has watched research, technology, institutions, and ordinary ingenuity make strange ideas workable. He acknowledges that innovation destroys jobs, creates environmental costs, and can outrun society’s ability to absorb its consequences. Still, Chapter Ten leans toward the belief that human ingenuity will keep delivering better possibilities and reasons for faith in public markets. Earlier, Booth taught us to distrust historical patterns dressed as promises. Here history comes close to reassurance. Even the apostle of uncertainty would like a little certainty about uncertainty.
One reason this lands differently now is that the machinery of investing has become almost frictionless while the machinery of distraction has become industrious. Broad, inexpensive funds are easier to buy than at any point in Booth’s early career, and the investor’s attention is under near-continuous solicitation. A phone can deliver an index fund, a frightening headline, an influencer’s certainty, and the button needed to act before the coffee cools. Access has improved faster than self-command.
Perhaps the sharpest contemporary irony is that financial technology has lowered the cost of sensible investing and the cost of sabotaging it at the same time. Booth’s distinction between signal and noise therefore matters less as a complaint about media excess than as a rule for allocating attention. Information deserves authority only when it improves a decision. Much of what arrives dressed as an emergency merely improves somebody else’s business model.
One could shelve “Stay Calm” near Morgan Housel’s “The Psychology of Money” and trace its lineage through Burton G. Malkiel’s “A Random Walk Down Wall Street.” Booth’s advantage is historical proximity. He remembers when the philosophy now packaged as common sense had not yet earned the adjective. His best pages show that sensible restraint was not discovered by people doing nothing. It was built by people doing a formidable amount of work so future investors could do less.
Under the investment argument sits the larger and more durable claim: agency does not require certainty. You can save without knowing future returns, plan without knowing your future desires exactly, choose tolerable risk without knowing when the next crash will arrive, and build skills without knowing which crisis will suddenly make one valuable. The less control Booth demands from outcomes, the more useful forms of control he discovers in conduct. This idea survives even where the market metaphor does not, which is why it matters more than the book’s individual prescriptions.
Life is where Booth’s borrowed vocabulary finally meets resistance. His paired terms can make contested questions look tidier than they are, and the history of evidence-based investing sometimes narrows into the history of Dimensional, whose success can function at once as example, evidence, and victory lap. The disclosures are candid about professional relationships, but candor cannot manufacture the distance a founder memoir lacks. Booth is saved from marble-statue syndrome by his appetite for collaborators, wrong turns, and lucky escapes. He is best company when he lets those complications remain visible.
Only then does the score feel worth stating: “Stay Calm” earns 82/100, or 4/5 stars. Its investment advice is largely familiar; the lived history behind that advice is not. The middle repeats itself. The life analogies occasionally travel farther than their evidence. Yet the book has a rare vantage and one durable insight: calm can be engineered. A portfolio, a plan, an adviser relationship, even an information diet can be arranged so that uncertainty becomes less expensive to inhabit. That is more useful than being told to relax.
Still, the book’s finest final image is not a portfolio but a telescope. Booth helps fund one at the McDonald Observatory, returning to his comparison between astronomy and financial research: better instruments enlarge what can be observed without shrinking the universe to what can be known. A telescope does not reassure the astronomer that everything beyond the lens will turn out well. It makes the boundary between evidence and darkness more exact. “Stay Calm” is most persuasive at that boundary. The future does not have to cooperate. The point is to build, invest, choose, and care in ways that do not require it to.

Review of advance copy received from NetGalley
When I started listening to the audiobook of Stay Calm, I was really interested in it. The information was easy to understand and digest, and it kept me interested and engaged. In fact, I was enjoying it so much that I recommended it to a friend that's just getting start with investing. But then somewhere around the 25% mark, it started getting really detailed regarding the history of the stock market, index funds, investment firms, etc. I can appreciate why the author wanted to share that information with readers and I think some people will find it fascinating, but it definitely got more detailed and went on longer than what I would have preferred. I believe there's a faction of people that will love this section, because understanding the history and how the stock market came to be can help people make informed decisions about their own investment strategies. Even if that section was a little long and boring for me, I can appreciate the value in it - but it was also a way to set up the next part of the book, which was about how he got involved in this world and the career path he's been on since then.
That being said, as the book meandered into the territory of more recent history, it started to feel like an ad for the author's firm. Detailed explanations of how and why they do things the way they do, what they learned along the way, experts they worked with and learned from, how honest they are with their clients, anecdotes about how they met with and acquired certain clients, etc. As the founder of an investment firm, he has every right to talk about it in his book, but it just started to feel heavy-handed to me. I was here for the practical advice and mindset shifts that I should apply when it comes to investing, not the 50-page ad for his company (I'm completely estimating the page count based on audiobook percentages - this is not a hard-and-fast page count).
I believe it was somewhere around the 60% mark that I felt I was finally getting to content I was hoping for, based on the synopsis. There was definitely some practical advice in there, though like with most self-help/financial/health/self-improvement/business books, the message started to feel a little repetitive. When it started to feel that way, I admittedly found myself losing focus and having to back up and listen to certain parts again.
As much as I wasn't necessarily wowed by this book, and definitely could've done with less advertising of the author's firm, I do think there was some good, practical advice in this book, particularly for people like me who are more conservative or risk-adverse. Having a better understanding of the market will definitely give me more confidence moving forward, and having faith in human ingenuity and the market's ability to bounce back will give me peace of mind with my investments.
There is one quote in the book about optimism that I really liked. Since the book is still in pre-publication, I'm not permitted to share it here at this time, but when you get to it (near the end of the book), perhaps it will strike you, too.
Thank you to AE Titles/Simon & Schuster Audio and NetGalley for the audiobook in exchange for my honest review.

Having a better understanding of the market will definitely give me more confidence moving forward, and having faith in human ingenuity and the market's ability to bounce back will give me peace of mind with my investments.
There is one quote in the book about optimism that I really liked. Since the book is still in pre-publication, I'm not permitted to share it here at this time, but when you get to it (near the end of the book), perhaps it will strike you, too.
Thank you to AE Titles/Simon & Schuster Audio and NetGalley for the audiobook in exchange for my honest review.

Know what you are getting. This is a light autobiography of David Booth (author) and his time creating and running Dimensional Fund Advisors/Dimensional as well as a smattering of simple strategy for investing. The autobiography gives context for his strategy for how to diversify, hold, and look away from the investment when things are challenging.
Does it work? Yes, in a way. The strategy boils down to buying broadly in the market, trust in the human ability to innovate, and keep the course even when the market crashes because it has repeatedly rebounded and produced 10ish percent gains year over year throughout the past century. He heavily discourages day trading and trying to beat the market. This has been generally proven to be the best strategy for the vast majority of people investing in the American stock market over the past 40 years.
One note, he does NOT say that you should never make the occasional gamble on a company that you specifically believe in. He also does not say much about the risk of pulling out when things are looking way UP to invest in something else, such as your own business. He also barely mentions rebalancing your portfolio.
What he DOES say is that stock picking, investing with someone who does not match your long term goals, constantly looking at the market, and panicking when the market tanks are great ways to fail in your investment strategy.
The final chapters, especially the chapter titled Investor's Guide is where the meat of the investment strategy lies. This is the chapter that warrants repeated review to identify sound, calm, and safe investment strategies. If you want to skip the history lesson on Small Cap investing, the autobiography, and the many anecdotes, you can go straight to the last section or to that chapter specifically.
All this being said, the book seems excessively long for the main bit of advice to stay calm when investing and not making emotionally driven choices. This final chapter is worth your time if you are new to or are an amateur investor.
Narration was good, smooth, and has clear enunciation without overemphasis. I felt that Matt Godfrey was a perfect choice for the narrator based on content.
Writing 2.5/5
Narration 5/5
Overall 3/5 for the audiobook.

Review of advance copy received from NetGalley
Great book to remind folks of the timeless advice on how to be long-term successful. Focus on the time in the market, revisit your goals, and managing uncertainty. Great read for folks to be reminded as we close out 2026. I also appreciated that the author put key takeaways at the end of each chapter that I will copy and reference again.
A few quotes that stuck out to me
Investing is fundamentally about managing uncertainty, and so is life. Which means that you may have spent your life developing your skill set for investing, without even realizing it. Because you already have this foundation, developing a mindset that will give you the patience and discipline to stay invested, even when things feel uncertain, should come naturally. I hope over time you may come to love uncertainty for all that it can give.
Planning and predicting are not the same thing. Predicting is about trying to foresee a specific future outcome, while planning is about preparing for a range of possible outcomes
We waste so much energy trying to control things that can’t be controlled, instead of focusing on what we can actually manage.
Perhaps the hardest part of compounding is staying the course when progress seems invisible

Review of advance copy
I acquired this book pre release through Dimensional. This book is a fantastic read for anyone curious about investing, mutual funds, the founding of Dimensional and its core philosophy of investing. This book makes it very clear to all investors that diversifying, investing for long term, staying true to your values, and trusting the market are the most important factors for investing. As a 20 year old man studying finance at university, this book was my entry into discovering, learning and developing my own personal philosophies on life long investing. This book provides practical knowledge to any investors, as well as Booth sharing his own personal experiences growing up, his relationships with his parents, friends, and professors that go beyond investing and urge us to be mindful of what really matters in life. Overall this was a great, inspiring read and the writing was exceptional. Bravo.

Thank you to NetGalley for the advanced audio copy of this book.
There are probably thousands of books out there trying to tell you how to work investments and get rich in a hurry. David Booth's book is more of a philosophical piece about what kind of attitude you should have when investing. As someone fairly new to the subject, I found this to be an informative read with plenty of good advice. The end of the book contains a helpful guide for people who are just getting started or starting over again.

Review of advance copy received from Goodreads Giveaways
Got this as a goodreads giveaway. I was trying to expand my book reading beyond fantasy and won this. It was an enjoyable easy read about cautious investing. Half memoir, half strategy, this book explains the perils of chasing individual stocks and instead success is all about the long game. In the end it made me review my 401k. Def a good read if you need some motivation to do some adulting better.

Quick read around the origin of index investing, and could see it being a very helpful guidebook for someone just starting to get into personal finance.
However, I’d guess most people reading this type of book already know why passive investing has become so popular and don’t need as much explanation of its benefits.
Also read like a sales pitch for his firm at times (honestly it probably is hard not to be biased in something like this).

A bit of a slog
The author rambles on a bit too long about his company.
Sometimes a bit more memoir than financial advice. However if you're
brand new to investing it will be time well spent. After forty years of investing for me though it was a bit tedious at times.

September 17, 2026This wisdom in this book is outstanding. I intend to give a copy to each of my children and grandchildren. I put it up there with John Bogle's The Little Red Book on Investing as a must read, especially for young people starting out in life and investing.

A book on the history of the stock market as well on DAVID'S story of his way to invest.

Interesting insight into the history of Dimensional. Good blend of Booth's story and his investing beliefs. I should watch Tune out the Noise again.
