- Robert Macfarlane
Robert Macfarlane is an excellent writer who thinks a lot about words and places and how the interaction between them tells us about our or someone else’s culture. His quote above greatly impacted me when I sat down to write my first book “Seeking Wisdom: Thoughts on Value Investing.” Constant reading (or, as Charlie Munger’s family referred to him - “a book with legs.”) is essential not only to be able to write but also to continually develop and improve your investment process.
At the beginning of each new year, I frequently write about one of the top questions I receive in my daily mail call. This year, I received quite a few questions about my daily reading.
Before I discuss what books I highly recommend for individual or institutional investors, I thought I’d discuss what makes a book compelling (at least to me.) Before anything else, I find a book where the writing and use of words are precise and exceptionally lyric, a rare find. Beautiful writing is a craft and something to be sought out every day. As much as Warren Buffett’s writings seem to ring of folksy wisdom (which they are), his writing is crystal clear in its messages. It cuts through any confusion and brings immediate light to traditionally stuffy topics. Such writing is the foundation of brilliant thinking.
In addition to writing of such a nature, there are four additional ways a writer can provide the reader with long-standing – and applied – wisdom. These include the following:
- A clear articulation of evidence
- Bringing new evidence to light
- It uses a latticework model
- Changes the reader’s process of thinking
The first category is essential to making a strong case for your thesis. Jack Bogle’s books were outstanding in proving, time and again, that high fees were absolute killers when it comes to investor returns. The founding father of indexing used books such as “Common Sense on Mutual Funds” and “The Battle for the Soul of Capitalism” to provide irrefutable evidence that not only was it hard to beat the markets in general, but it was nigh impossible to beat them when you paid high management fees. His discussion of costs related to high portfolio turnover was an eye-opener on how managers see the long term as a disadvantage in their business model.
Another characteristic of a great investment book is how the writer brings new information to light. Benjamin Graham’s classic “Security Analysis” was brilliant in bringing forth an entirely new concept of understanding the value of an investment versus its price, which was critical to achieving excellent long-term results. His later book, “The Intelligent Investor,” was just as crucial in bringing the concept of margin of safety and Mr. Market to individual investors. The former became a handbook for professional investment managers, while the latter was written for private individual investors. Graham’s ability to bring forth new ideas in a simplified and easy-to-understand manner changed the dynamic entirely regarding investment management.
Combining multiple subject matters, some with no seeming connection with investing, is another form of outstanding investment writing. Classically referred to as consilience, Charlie Munger created the term “latticework of mental models.” There have been quite a few great books covering this, including the works of Michael Mauboussin (“More Than You Know” and “Think Twice”) and Robert Hagstrom (“Investing: The Last Liberal Art”). I would be remiss not to mention Shane Parrish’s “The Great Mental Models, v. 1-4, along with his outstanding website, Farnam Street.
Last but not least are books that can change the very process by which an investor looks at investing. I refer to it as how to invest rather than what to invest in. These books can have the most significant impact on your investment approach. The classics from Graham, Bogle, and Buffett are great examples. Switching from active investing to indexing and creating a value-based approach can completely change how investors allocate their capital. However, there are other examples by lesser-known authors that are equally important. These include “Excess Returns” by Frederik Vanhaverbeke, “Investing for Growth” by Terry Smith, and “The Manual of Ideas” by John Mihaljevic. All of these are excellent editions by which to learn all new strategies and measures to improve your investment returns.
While I’ve listed the criteria necessary for a great investment book, there are also some personal characteristics a successful value investor needs that complement whatever you might be reading.
Always Keep Learning
A good investor has a mind that constantly thirsts for new theories and facts. I read at least two hours daily and could use two more each day. A great investor is open to all kinds of content, no matter how far away it might seem from investing. The great thing about learning is that it never gets old and, over time, can give you a significant advantage over other investors. What other fields have such opportunities?
Always Question Your Hypothesis and Facts
At Nintai, we often use a process we refer to as breaking the case. In this process, we keep knocking down our assumptions (growth, free cash flow, competitive strength, etc.) until we reach a valuation that is wholly impaired. It is vital that investors be able to accept information and data that, no matter how unappealing, changes their business case or valuation.
What Didn’t Work Before Might Be Great in the Future
Just because something worked in the past doesn’t mean it will work forever. It’s equally important to understand the inversion of that is equally valid. Just because a business model wasn’t a great investment opportunity in the past, things like technology innovation or regulatory changes might make the business model a better investment in the future. A great case of this is Warren Buffett’s investment in railroads. It has become an outstanding investment with changes in regulations, modal transportation transformation, and operational improvements.
Keep Your Emotions in Check
Last, but most important, is the ability to keep your emotions under control. No matter what reading you do or the evolution of your investment approach, letting your emotions drive your decision-making will lead to truly awful results.
Conclusions
It’s surprising how often I get questioned about what I read. As a writer, it’s a surprising amount. There is so much to learn in this world of the internet, e-books, and online learning. For those starting on their investment journey, developing a daily reading regimen is an outstanding way to understand better how to achieve better results. You will be surprised how a “latticework of mental models” will help you better understand the financial world and also help you understand the world in its entirety. Very little knowledge that you acquire will go to waste. If nothing else, you’ll be the life of the cocktail circuit, and there are worse things than that.
