Book Review: The Joys of Compounding

The Joys of Compounding: The Passionate Pursuit of Lifelong Learning. 2020. Gautam Baid, CFA. Columbia Business School Publishing.

In The Joys of Compounding: The Passionate Pursuit of Lifelong Learning, Gautam Baid, CFA, a value investor and portfolio manager at Summit Global Investments, offers new opportunities to learn and re-learn critical lessons that will make us better investors and individuals. The author’s pursuit of lifelong learning through constant reading, reflection, and thinking will inspire investors to enhance their skills.

For Baid, value investing provides not only an investing strategy but also an intellectual toolkit for achieving a deeper understanding of the world around us, including ourselves. He presents a holistic approach to value investing and philosophy from his wide-ranging reading, combining practical approaches, self-cultivation, and business wisdom. He integrates the strategies and wisdom of renowned investors whose teachings have stood the test of time, such as Ben Graham and Charlie Munger, by distilling investment and life lessons into a comprehensive guide. Baid successfully demonstrates the practical applications of their ideas in business, investing, and decision making, while also showing that these concepts can be applied to one’s personal life with just as much benefit.

The author reminds us of the importance of being a learning machine and that the best investment we can make is an investment in ourselves. He firmly believes that being a lifelong learner has made him a better investor. Self-improvement is the best way to spend some time every day, Baid maintains, and carving out just an hour each day to read is easier than people think. Instead of indulging in adrenaline-laced rushes of emails and social posts while multitasking, one can dedicate the time to deliberate practice, which entails focused attention on a specific goal of improving performance.

My own experience has taught me that studying for and passing examinations for financial and real estate designations is an effective form of deliberate practice and deep work, which consists of non-distracted focus on a cognitively demanding task. The exam preparation process provides critical feedback similar to that of a coach or a trainer, a vital component of deliberate practice.

Compound knowledge building will create a repository of knowledge or a “latticework of mental models” that will allow individuals to draw on their own and others’ instincts, judgments, and experiences. Baid points out that reading just 25 pages per day equates to 9,000 pages per year, which would enable one to read Robert Caro’s 1,336-page book The Power Broker nearly seven times in one year. Time, the currency of life, is a non-renewable resource that becomes increasingly scarce for everyone as each day passes.

The author provides practical examples of placing a high value on time, such as avoiding a long daily commute to work and outsourcing all non-core, time-consuming menial tasks. Although Baid does not present personal return data to demonstrate market outperformance, he notes that he has achieved financial freedom through his passionate pursuit of lifelong learning. This has allowed him to pursue work that he wants to do for self-fulfillment rather than out of necessity.

Baid offers strategies for successful common stock investing, including using checklists to improve decision making and keeping a journal to enhance self-reflection. Checklists are a systematic means of engaging the rational brain, which protects investors from the “cocaine brain” that can push them into greed mode. It makes better sense to take actions based on pre-established rules and checklists rather than out of pure emotion. Good checklists, in Baid’s opinion, are brief, precise, efficient, and easy to use even under difficult conditions. They do not try to spell out everything, instead providing reminders of only the critical steps.

Because people are not rational animals but rather rationalizing animals, journaling offers us an essential tool for self-awareness, self-reflection, and successful investing. The vast majority of investors do not keep a journal. Baid recommends maintaining a journal that contains the original investment thesis at the time of the stock’s purchase, as well as the rationale for the sale of the shares.

A journal is the most objective way to remain true to principles and avoid hindsight bias. It also helps investors continuously learn from their mistakes. The resulting insights are some of the greatest teachers in life, business, and investing. Learning from one’s mistakes, as well as vicariously learning about others’ mistakes through voracious reading, offers significant benefits over an investing lifetime, which is typically a long span.

Regarding strategies for improving investment decision making, I wholeheartedly agree with the author’s advice to read more financial history and fewer “expert” financial forecasts. Having a solid understanding of financial history is vital to develop the “nerves of steel” and poise required during the inevitable periodic disruptions in financial markets. Studying history creates awareness of certain possibilities that would otherwise not be considered and facilitates a medium- and long-term, rather than a short-term, approach.

As an example of the value of maintaining a long-term perspective despite political noise, Baid cites the strong performance of India’s major stock market (Sensex) during 1984–2019, a period that witnessed nine different prime ministers or forms of government (majority versus minority). In India, a significant amount of uncertainty and apprehension surrounds government formation during election years. Throughout an electoral campaign, investors fear the market will drop precipitously if a coalition government comes to power.

During the nine episodes examined by Baid, however, the Sensex’s compound annual growth rate (CAGR) was negative in only one case (–5.3% in 1996–1998). The other eight periods’ positive CAGRs ranged from 4.0% in 1999–2004 to 48.6% in 1989–1991. The author also details the maximum drawdowns under different political regimes in India’s Nifty 50 index since 1991 and the United States’ S&P 500 Index since the late 1920s. The substantial interim stock price volatility had no material impact on either country’s long-term equity market performance.

Finally, picking up on the popular characterization of compound interest as the most powerful force in the universe, this book forces readers to think about compounding in terms of human traits such as positive thoughts, good health, good habits, wealth, knowledge, and goodwill. As with the financial benefits of interest compounding over decades, individuals should focus on these traits at a young age. Doing so enables the powerful force of compounding to work its magic over very long periods.
