Richard Thaler, Behavioral Economics and A.I.

Richard Thaler is the third Behavioral Economics giant to be awarded a Nobel Prize in Economics after Daniel Kahneman (2002) and Robert Schiller (2013). I found his intellectual autobiography very enlightening:

 Here's the 10/9/2017 Nobel Prize press release, from which I quote this fascinating tidbit:
Lack of self-control: Thaler has also shed new light on the old observation that New Year's resolutions can be hard to keep. He showed how to analyse self-control problems using a planner-doer model, which is similar to the frameworks psychologists and neuroscientists now use to describe the internal tension between long-term planning and short-term doing. Succumbing to shortterm temptation is an important reason why our plans to save for old age, or make healthier lifestyle choices, often fail. In his applied work, Thaler demonstrated how nudging – a term he coined – may help people exercise better self-control when saving for a pension, as well in other contexts.
and here's a quote from a New York Times article:
Professor Thaler has played a central role in pushing economists away from that assumption. He did not simply argue that humans are irrational, which has always been obvious but is not particularly helpful. Rather, he showed that people depart from rationality in consistent ways, so their behavior can still be anticipated and modeled.
Richard Thaler is one of the fathers of Behavioral Economics, whose basic assumption is that human beings, far from being the Homo Economicus of orthodox, neo-classical economics, can behave in irrational ways. Tangentially related is the subject of Artificial Intelligence. A commentator in the New York Times article mentioned above, Bey Melamed posted: "I wonder how Thaler's theories clash with / are supported by or commensurate with artificial intelligence. If / when AI has reached sufficient sophistication it should be able to (or even measured by the ability to) make human decisions with appropriate irrationality sprinkled in, no?"

My response to this comment is that alternatively, in a more sinister vision of the future, AI could be programmed to follow all the rules and behaviors of Homo Economicus, never showing the irrational idiosyncrasies exhibited by humans. Since we have a huge theoretical framework for just such creatures, it would make sense to replace human agents by algorithms across many domains. It is already the case in Financial Markets, where algorithmic, non-human traders have been taking over many tasks human traders used to perform. That would, of course, accelerate the replacement of humans by programs and algorithms, a pervasive process already under way. A failure to adapt to this trend will result in negative outcomes such as mass unemployment, community disintegration and social upheaval.

Here's another great New York Times article (from a 2001 NYT magazine profile) on Richard Thaler, written by Roger Lowenstein, the author of When Genius Failed, the definitive book on the saga of the hedge fund Long Term Capital Management (LTCM, 1994-1998):
Thaler spearheaded a simple but devastating dissent. Rejecting the narrow, mechanical homo economicus that serves as a basis for neoclassical theory, Thaler proposed that most people actually behave like . . . people! They are prone to error, irrationality and emotion, and they act in ways not always consistent with maximizing their own financial well being.

Michiko Kakutani

Michiko Kakutani, one of the most feared, respected and fearless book critics of our times is leaving her high priestess perch as the New York Times Chief Book Critic. I am sure she will keep reviewing books from wherever she lands next. As I am sure many writers are breathing a sigh of relief at the news of her stepping down. She will be greatly missed by book lovers. Here is a list of some of her more trenchant and prophetic reviews of the last 4 decades.

“Beloved.” “Infinite Jest.” “White Teeth.” “Team of Rivals.” Four decades of signature reviews and essays by The Times’s Pulitzer Prize-winning book critic.

Pity the Bear Chin

I wrote this last year on 3/2/2016. One year later and the Bears are still taking it on the chin. Only the S&P 500 is 450-point or about 20% higher!

The Bears are taking it on the chin this week, the S&P 500 Index having breezed through the 1950 level of resistance. It will however all be meaningless if it dips back below it by Friday's close. If the index closes above 1950 on a weekly basis, 2000 becomes the next big (huuuuuuuge) resistance level. Everything is still in play. I might (don't hold me to it) write up a more detailed analysis of the stock market this coming weekend.

What Have You Done For Me Lately?

Shameful. Unforgivable. I'm not big on soccer but this has to be the most cruel sacking in the history of sports.

In soccer, as in life these days, you're as good as your last performance. As they say in the financial markets, past performance is in no way indicative/predictive of future performance. In other words, "what have you done for me lately?" is the only question that matters in this brave new world. Is it good or bad? I think this is no longer a moral issue, it's just the zeitgeist. Get used to it.

The Other Wall (No Politics, I Swear, Read On)

There's a Wall Street saying that goes like this:

A bull market climbs a wall of worries.

As many other Wall Street sayings, it reflects a true phenomenon. When the stock market is bullish, as it has been since 2009, every piece of bad news is absorbed by each and every market participant, chewed a little (i.e. the market goes down a bit) and then fully digested. And then, a few days (or weeks at most) later, the market soldiers on and makes new highs.

What this means is that, in a bull market (which is nothing else than a rising market), the fundamentals, the technicals and the sentiment are so good that one or two pieces of short-term bad news can only be but a temporary setback, a soft, very climbable "Wall of Worries". And the supply of stocks that suddenly materializes (often at a lower, thus more interesting price) as a result of those worries is gladly devoured by the market participants and provides fuel for the next leg up.

And I believe we've basically been in this configuration since the horrendous low reached in the doldrums of the "Great Recession" of 2008-2009, namely the infamous 666 level reached by the S&P 500 Index in early 2009.

This bull market is still going on strong 8 years later, which makes it one of the longest bull markets of all time ("all time" sounds impressive but it only means since people have been studying these things, which is about 100-odd years ago).

This is what I wrote exactly one year ago:

It looks like the 1810-1830 support band for the S&P 500 has been tested successfully again. 
That's the 5th time since April 2014, which reinforces it as support. The Bears have to decisively pierce this 1800-ish support level to have their views vindicated. The onus is on them.
Granted the Bulls have a lot of resistance levels above too (More on this in future posts), but don't let yourself be scared out of your long-term investments by the voices of doom. They're always loudest near significant bottoms.
To add meat to my analysis, I'll make a probabilistic prediction (which should be the only kind of prediction when it comes to markets, as they are dynamic and chaotic): I give the S&P 500 a 65% chance of rebounding from here.

Which brings me back to the Wall of Worries. Well, it looks like we keep climbing it. So much has happened since last year, much of which would very much qualify as proverbial walls of worry. Yet, the market keeps climbing and climbing. It's up about 25% (yesterday, the S&P 500 closed above 2300 for the first time "in the history of the universe" 😃) since I wrote the paragraph above and will keep climbing until it doesn't! When would that be? I can't tell you, I'm just a Technical Analyst, not a fortune teller!

See, like I promised, no politics! Have a great day.

Food for Thought

“The inherent irony of the efficient market theory is that the more people believe in it and correspondingly shun active management, the more inefficient the market is likely to become.” 

Seth Klarman, who manages the $30-billion hedge fund Baupost Group.

The More You Store (In Your Brain), the More Additional Storage Room You Have!

"Memory storage [in the brain] creates capacity for more storage" Bob Bjork, UCLA. 

In other words, contrary to what one may think, the more you know, the more room for additional knowledge you have in your brain. 

Put yet another way, your brain, far from being a finite box (or a hard drive), is infinitely elastic and the more information and knowledge you put in it, the more you CAN put in it.

Best MOOC Ever

If you have time to take only one MOOC, I would very very very strongly recommend the really really really awesome EdX Course on The Science of Everyday Thinking given by the University of Queensland, Australia
Psychology is one of my favourite subjects (Technical Analysis is basically the Psychology of Stock Trading) but this class was such a revelation. It basically catches you up on all the Social Psychology, Cognitive Biases Studies and Behavioral Psychology advances of the past 50 years in an engaging, fun and immersive way. You'll hear from all the grandees of the discipline (Daniel Kahneman, Nisbett and Ross, Elisabeth Loftus, etc... ; even the guys from the MythBusters TV show and more). I believe it's been rated as one of the best MOOCs (Massive Open Online Course) of all time. 

Learn how to think better, argue better, and choose better.
