Chemistry and Markets

Since the topic of chemistry/market analogies has come up, I’m reminded of something I noticed while studying economics. Anyone else notice some resemblance between stoichiometry and the Cobb-Douglas production function?

Stoichiometry and the reaction rate equation: r = k(T) * A^n * B^m

And the Cobb-Douglas production function: Y=AL^{\beta}K^\alpha

What kind of “chemical” reactions can we find in the markets?

Something like this?

Trader-Cash_p + Stock <-> Trader-Stock + Cash_p

An important difference with this “reaction” is that _p, which is price, fluctuates; whereas chemical reactions always have the same stoichiometry. So, are there any useful analogies?

Fascinating Insights From Nobel Prize-Winner Robert Shiller

On why so many experts missed the 2008 financial crisis: “Experts have always missed big events like this. If you look at the record of statistical forecasting models, they tend to get to the recession when it’s starting to come. A casual observer might start to worry about it. Forecasting it years out, they don’t get; in particular, if you look at the Great Depression of the 1930s, nobody forecasted that. Zero. Nobody. Now there were, of course, some guys who were saying the stock market is overpriced and it would come down, but if you look at what they said, did that mean a depression is coming? A decade-long depression? That was never said.”

On short-term thinking: “I think that there’s too much faith in analysis of short-term data. You see some pattern, and you can do a statistical test and prove that will prove that it is significant or passes the smell test to a statistician. But the problem is, the world is always changing. It’s not a stable thing. The underlying human parameters may be stable, but you can see that there is institutional and cultural evolution, and it’s not something that you can quantify.”

World’s Oldest Trader

World’s oldest Value Investor. Duly noted (hat tip to Mr. Melvin) that Irving Kahn is a former Ben Graham assistant and likes to buy and hold for long time– and not really a “trader” per se.

From the WSJ:


Discipline has been a key for Mr. Kahn. He still works five days a week, slacking off only on the occasional Friday. He reads voraciously, including at least two newspapers every day and numerous magazines and books, especially about science. His abiding goal, he told me, is “to know much more about the stock I’m buying than the man who’s selling does.” What has enabled him to live so long? “No secret,” he said. “Just nature’s way.” He added, speaking of unwholesome lifestyles: “Millions of people die every year of something they could cure themselves: lack of wisdom and lack of ability to control their impulses.”

Here is a link to his current portfolio (he includes a land-based driller). 

Reaction in Your Brain When Your Market View Is Completely Wrong

Eric Barker has a new article (link here) on how to win every argument. The article had a point which made me think whether the same situation happens in trading.

brainSo it quoted an experiment by psychologist Drew Westen, which showed to supporters, footage of their favorite candidates completely contradicting himself. The experiment found that as soon as the people realized that the information contradicted their world view, the parts of the brain that handle reason and logic went dormant, while the parts of the brain that handle hostile attacks – the fight-or-flight response – lit up. Essentially logic gets thrown out the window, and it just becomes a fight where you do anything to win.

A similar situation occurs in trading, when you have a certain expectation of how the market should behave. E.g. you might for various reasons, think that the market will go up. So when the market does not follow what you expect, you might initially make up excuses for it. However when the market continues to go completely in the opposite direction of what you expect, your logic and reasoning centers would shut down, your fight-or-flight response kicks in, you treat it like a hostile attack on you, and you would do anything to win (or not lose), e.g. keep averaging down. I’m sure this sequence of events led to many traders blowing up their accounts. It is pretty interesting that the experiment showed this as a ‘natural expected’ behavior.

As always, trade what you see, not what you think.

THE BEST TRADERS ARE HUMBLE

When an ordinary man attains knowledge, he is a sage; when a sage attains understanding, he is an ordinary man.

– Anonymous

With some technical trading knowledge and experience, you become a trader.

But when you become consistent and profitable, you feel ordinary again. This is because you’ve grown aware of the great uncertainty you face in the markets.

You’ve gained a strong appreciation of risk. In fact, your respect for risk is so deep that you would feel humble. And in that sense, you will feel ordinary.

Observation, Experience, Memory and Mathematics

“Observation, experience, memory and mathematics – these are what the successful trader must depend on. He must not only observe but remember at all times what he has observed. He cannot bet on the unreasonable or the unexpected, however strong his personal convictions may be about man’s unreasonableness or however certain he may feel that the unexpected happens very frequently. He must bet always on probabilities – that is, try to anticipate them. Years of practice at the game, of constant study, of always remembering, enable the trader to act on the instant when the unexpected happens as well as when the expected comes to pass.

“A man can have great mathematical ability and an unusual power of accurate observation and yet fail in speculation unless he also possesses the experience and the memory. And then, like the physician who keeps up with the advances of science, the wise trader never ceases to study general conditions, to keep track of developments everywhere that are likely to affect or influence the course of the various markets. After years of the game it becomes a habit to keep posted. He acts almost automatically. He acquires the invaluable professional attitude that enables him to beat the game – at times! This difference between the professional and the amateur or occasional trader cannot be overemphasized. I find, for instance, that memory and mathematics help me very much. Wall Street makes its money on a mathematical basis. I mean, it makes its money by dealing with facts and figures.” (more…)

HOW TO MAKE BETTER DECISIONS

When you have the time make a decision to watch the following program on making better decisions.  You may find that you made the right decision to do so.
FROM THE INTRODUCTION:According to science: We are bad at making decisions. Our decisions are based on oversimplification, laziness and prejudice. And that’s assuming that we haven’t already been hijacked by our surroundings or led astray by our subconscious!
Featuring exclusive footage of experiments that show how our choices can be confounded by temperature, warped by post-rationalisation and even manipulated by the future, Horizon presents a guide to better decision making, and introduces you to Mathematician Garth Sundem, who is convinced that conclusions can best be reached using simple maths and a pencil!

Our Favorite Non-Investing Books About Investing

A few people have asked me over the past couple of weeks to share some of my favorite books outside of finance that are applicable to investing. The majority of these books are based on psychology because it plays such an important role in making better investment decisions. Here’s my list:

Mindless Eating: Why We Eat More Than We Think by Brian Wansink
The analogy between your finances and losing weight has been used over and over again throughout the years. It’s a useful analogy because the decisions in both activities are mainly affected by people’s behavior (or a lack of behavioral change). A couple of my favorites stats from this book: (1) People make an average of over 200 food-related decisions each day and (2) It’s estimated that 95% of all people who lose weight on a diet gain it all back.

Influence: The Psychology of Persuasion by Robert Cialdini
This one has been recommended by Charlie Munger on a number of occasions so I finally read it this year. It’s one of the best psychology books I’ve ever read. This book really helps you step into the shoes of the mind of a marketer or sales-person trying to get you interested in their product. These people are masters at getting into people’s heads to get them to act. Cialdini also touches on the social proof theory, which states that most people look to see what others are doing to figure out acceptable behavior. (more…)

Mastering the Art…

“You have all these people trying to come up with formulas to beat the market. The market is not a science. The science may help increase the probabilities, but to excel you need to master the art of trading.”  
– Mark Minervini, Stock Market Wizards
“After a certain high level of technical skill is achieved, science and art tend to coalesce in aesthetics, plasticity, and form. The greatest scientists are artists as well.”

– Albert Einstein

To achieve trading greatness, one must first become an artist. To become a true artist, one must first master the art.
What does it mean to “master the art” of trading? What kind of nuances and subtleties are involved?  What range of experiences, processes, and deep situational knowledge is required?
