Lockdown Learning: A Reading List for Behavioral Investing

If, like me, you find yourself with an unexpected amount of leisure time you may want to spend some of it catching up on your investing education. At the very least it’ll be a distraction from the chaos out in the real-world, and even if you don’t learn anything it’ll probably stop you from trading …

A Liberal Arts Investor’s Reading List

A Little Wisdom Goes A Long Way

These days it’s hard to actually see out of the thicket of new books on the topic behavioral finance, a deluge inversely proportional to the actual impact of behavioral economics on the real world, other than through the dubious delights of default choice. And, of course, I'm adding to the bonfire with my own review of the subject in Investing Psychology: The Effects of Behavioral Finance on Investment Choice and Bias.

If we think a bit wider, though, as a liberal arts investor, there are a few books people shouldn't die not having read. Following Charlie Munger’s dictum :
“Wisdom acquisition is a moral duty. It’s not something you do just to advance in life. As a corollary to that proposition which is very important, it means that you are hooked for lifetime learning. And without lifetime learning, you people are not going to do very well. You are not going to get very far in life based on what you already know.”
So here, in no particular order, are the books I go back to again and again.

Screwed: Fictional Profits, False Accounting and Financialization

Double Entry: How The Merchants of Venice Created Modern Finance by Jane Gleeson-White
 
"So it has come to this. The global biodiversity crisis is so severe that brilliant scientists, political leaders, eco-warriors, and religious gurus can no longer save us from ourselves. The military are powerless. But there may be one last hope for life on earth: accountants."
 
Back in the Thirteenth Century, when Venice ruled the waves, we can find the origins of modern capitalism.  Back then the portents were vague, but the invention of bookkeeping and the introduction of Arabic numerals foreshadowed a revolution based on the stunningly original idea of being able to figure out whether or not your business was making a profit.

Roll forward six hundred years and we find that those inventions, suitably adapted, have not just stood the test of time, but have insinuated themselves into every nook and cranny of modern life.  Welcome to the world of financialization where earnings per share is an imaginary number and money is the only objective measure of everything. Only it isn't.

Self-Organizing the Investment Blogosphere

"Investing is hard.  It is hard for everyone, including the most successful investors in the world.  Nevertheless, investing is one of those adult responsibilities we all need to come to terms with.”
Abnormal Returns: Winning Strategies from the Frontlines of the Investment Blogosphere by Tadas Viskanta

Trying to understand the amorphous creature that is the financial blogosphere is an exercise as hopeless – and as pointless – as the quest for the Holy Grail.  We don’t know what it is, we don’t know what it does and if we ever found it, we wouldn’t recognise it.

Yet, by some mysterious self-organising mechanism, the blogosphere is a system which manages to attain some form of order and structure.  In the midst of this mayhem is Tadas Viskanta’s Abnormal Returns, a “forecast free” daily compendium of the best and most lucid writings from around the web, interleaved with posts giving a sideways insight into the ideas that drive the site.  Combined, those ideas have now been integrated into a book which is probably the best definition of the challenges facing the modern investor now extant.

One Price To Rule Them All

Models. Behaving. Badly: Why Confusing Illusion With Reality Can Lead to Disaster, On Wall Street, And In Life by Emanuel Derman
"In physics there may one day be a Theory of Everything; in finance and the social sciences, you have to work hard to have a usable Theory of Anything."

The idea that the theories of physics are qualitatively different from the models of finance has been one of the longest running themes on the Psy-Fi Blog – all the way back to this post on Newton’s Financial Crisis. Now the polymathic ex-theoretical physicist, ex-quant for Goldman Sachs, Emanuel Derman, has written a book on this very subject; and very unusual it is too.

Being Derman this is no ordinary description of the problem, but one that roams widely across the realms of science, philosophy, autobiography and finance. At the heart of the discussion is a key idea, that the Law of One Price is a basis for most securities valuations and works not because it’s a deep law of nature but because it’s a simple rule of thumb that can’t be misused in any meaningful way.

When Incentives Go Bad

Strings Attached: Untangling the Ethics of Incentives by Ruth W. Grant


Way back in ’76, when heels were high, flares were wide and hair was long (for the men, at least) a couple of dudes called Michael Jensen and William Meckling proposed a solution to a problem that had vexed even the founders of economics. They attempted to resolve a puzzle that started with Adam Smith and which has ended in the crash to end all crashes; and as ever we’re looking at a set of consequences which was unforeseeable in advance but seems inevitable in retrospect.

The problem was how do you align the interests of the owners of corporations – the shareholders – with those of the managers of the companies? The solution was ingenious, but the chain of events it set off has exposed the nature of the concept of incentives. Because, it turns out, incentives are not neutral economic things, but strike at the very heart of what it means to be human.

100 Ways To Leave Your Lucre

Irrationality, The Enemy Within, by Stuart Sutherland

For those of us interested in how people manage to behave oddly in the face of anything to do with finance, these recent years have been good, as a range of intelligent books have been published on the topic. From Freakonomics and Predictably Irrational to The Undercover Economist and Nudge, plus a whole host of imitative single word follow-ons, we’ve been treated to real economists demonstrating a hitherto unforeseen talent for communicating with the unwashed masses. Nonetheless, despite this, there is still no better introduction to the subject of behavioral psychology than Irrationality, by Stuart Sutherland, even though it originally dates from 1992. 

Unsurpisingly, although the world has moved on, people haven’t; and the mistakes they made twenty years ago they still make today. We are still the enemy within.

Robert Cialdini and the Weapons of Influence

“Well here, again, Cialdini does a magnificent job at this, and you’re all going to be given a copy of Cialdini’s book. And if you have half as much sense as I think you do, you will immediately order copies for all of your children and several of your friends. You will never make a better investment.”; Charlie Munger on The Psychology of Human Misjudgement.
A World Too Complex

One of the recurring themes in behavioral economics is the concept of bounded rationality: the idea that we’re perfectly rational up to the point at which our limited brainpower stops out. Cialdini’s Influence turns this idea on its head, and argues that it’s our brainpower that’s created a world that’s too complex for us to understand: and that the result of this is that we take mental shortcuts, which then open us up to exploitation at the hands of any unscrupulous third-party. Which is pretty much everyone, these days.

We'd argue that these weaknesses are exposed directly in stockmarket investing when we're not so much fooled by other people as dumbfounded by our own brains.  Influence is not about investing, but about psychology: which makes it essential reading for everyone, but especially investors.

John Kay’s Obliquity

Oblique

Many of the great mistakes of history, including the problems financial markets have continualy re-experienced, have been caused by a basic error of judgement – the idea that it’s possible to define, plan and control the outcomes of the world around us despite the rampant uncertainty we daily take in our strides. So instead of relying on expert judgement and feeling our way carefully towards outcomes we’ve found ourselves traduced by people with tunnel vision and a strong but unjustified confidence in their ability to navigate unerringly to a correct solution, whatever that might be.

This is the argument presented in a new addition to the popular literature on human decision making by the economist John Kay. At the heart of this book, Obliquity, are many arguments readers here will find familiar, but perhaps the most notable is the idea that those economists who argue that people are irrational are wrong. It’s the economists who misunderstand the nature of human decision making, not their subjects,
