We often confuse luck with skill, especially in the stock market.  In fact, Michael J. Mauboussin has written a worthy read on separating the two in his newest book The Success Equation:  Untangling Skill and Luck in Business, Sports, and Investing.  But long before the contemporary discussions of luck versus skill, ancient speculators were enthralled by luck’s deceptive ways of making mere mortals feel godlike.  However, that sense of omniscience, just like a string of luck, is fleeting and continues to lure modern speculators into a trap today just like it did Saxon-les-Bains, a man of culture, almost 150 years ago.  In a 1873 letter to The Spectator entitled “A Study in the Psychology of Gambling” Saxon-les-Bains describes his gambling experience in Monte Carlo.

And what was my experience?  This chiefly, that I was distinctly conscious of partially attributing to some defect of stupidity in my own mind, every venture on an issue that proved a failure; that I groped about within me something in me like an anticipation or warning (which of course was not to be found) of what the next event was to be, and generally hit upon some vague impulse in my own mind which determined me: that when I succeeded I raked up my gains, with a half impression that I had been a clever fellow, and had made a judicious stake, just as if I had really moved skillfully as in chess; and that when I failed, I thought to myself, ‘Ah, I knew all the time I was going wrong in selecting that number, and yet I was fool enough to stick to it,’ which was, of course, a pure illusion, for all that I did know the chance was even, or much more than even, against me.  But this illusion followed me throughout.  I had a sense ofdeserving success when I succeeded, or of having failed through my own willfulness, or wrong-headed caprice, when I failed.  When, as not infrequently happened, I put a coin on the corner between four numbers, receiving eight times my stake, if any of the four numbers turned up, I was conscious of an honest glow of self-applause… (more…)

Artificial Intelligence, Chess, and the Stock Market

In 1997 chess grandmaster Gary Kasparov met the Singularity. And the Singularity won.

In 1985 Kasparov easily beat a chess-playing computer, even though he resorted to a trick to out-Kasparov the machine’s Kasparov program. Eleven years later, though, the chess legend struggled with Deep Blue, a computer with even more powerful processing power. But even Kasparov couldn’t compete with Deep Blue once its development team doubled the processing power a few years later.

Kasparov was beat, but he drew new lessons from the run-in that he details in New York Review of Books. These lessons might help you become a smarter–and less anxious–trader.
According to Kasparov, the exponential gain in technology didn’t ruin the game; it actually had some surprising aftershocks. 

First, the game became more global. With access to computer programs that could train students available anywhere and everywhere, students far from the chess epicenter of Russia began to crop up.

Kasparov says:

“With the introduction of super-powerful software it became possible for a youngster to have a top- level opponent at home instead of need ing a professional trainer from an early age. Countries with little by way of chess tradition and few available coaches can now produce prodigies.” (more…)

Three Myths of Trading Psychology

  
  Education
#  #  #  #  #  #  #  #  #  #  #  #  #  #  #  #  #  #  #  #

Myth #1: Emotions are at the root of trading problems. Yes, emotions can interfere with concentration and performance, but that doesn’t mean that they are a primary cause. Indeed, emotional distress is as often the result of poor trading as the cause. When traders fail to manage risk properly, trading size that is too large for their accounts, they invite outsized emotional responses to their swings in P/L. Similarly, when traders trade untested patterns that possess no objective edge in the marketplace, they are going to lose money over time and experience an understandable degree of emotional frustration. I know many successful traders who are fiercely competitive and highly emotional. I also know many successful traders who are highly analytical and not at all emotional. Trading is a performance field, no less than athletics or the performing arts.Success is a function of talents (inborn abilities) and skills (acquired competencies). No amount of emotional self-control can turn a person into a successful musician, football player, or trader. Once individuals possess the requisite talents and skills for success, however, then psychological factors become important. Psychology dictates how consistent you are with the skills and talents you have; it cannot replace those skills and talents.

 Myth #2: Anyone, with dedicated effort, can get to the point of trading for a living. That is nonsense. How many people make their living from acting or musical performance? What proportion of people playing sports can actually make their livelihood from athletics? Many people play chess or poker, but how many can sustain a living from it?Quite simply, to make a living from any performance activity means that you are consistently good at what you do. Not everyone has the talent, skill, or drive to be that successful—in any field. Across the many traders I’ve met in various settings, from home-based, independent traders to professional ones in firms, the best predictors of trading success have been the size of the trader’s account and the resources available to the trader. If a person were to make 30% per year on their accounts year after year, they would be among the world’s most successful money managers. Most money managers of mutual funds, hedge funds, and pension funds cannot sustain such performance. This leads the trader to accept huge leverage and court a risk of ruin when an inevitable string of losing trades occurs. Indeed, such excess leverage is a main cause of emotional distress in trading. Take a look at how the Turtles made their money: they learned a trading method, learned to be consistent with that method, and were given enough money by Richard Dennis that they could trade multiple markets with enough size to scale into positions in each. Even with those resources, not all of the Turtle students could succeed. Talent, skill, and opportunity are the ingredients of success, and these are relatively normally distributed in the trading population, just as they are relatively normally distributed in the population at large.

John Hussman writes:

I’ve long been fascinated by the parallels between Chess and finance. Years ago, I asked Tsagaan Battsetseg, a highly ranked world chess champion, what runs through her mind most frequently during matches. She answered with two questions – “What is the opportunity?” and “What is threatened?”

He adds:

The final minutes of a Chess game often go something like this – each side has exhausted most of its pieces, and many pieces that have great latitude for movement have been captured, leaving grand moves off the table. At that point, the game is often decided as a result of some seemingly small threat that was overlooked. Maybe a pawn, incorrectly dismissed as insignificant, has passed to the other side of the board, where it stands to become a Queen. Maybe one player has brought the King forward a bit earlier than seemed necessary, chipping away at the opponent’s strength and quietly shifting the balance of power. Within a few moves, one of the players discovers that one of those overlooked, easily dismissed threats creates a situation from which it is impossible to escape or recover.

Hussman lays out a great case for trend following–even though that is not his intent.
