The Dominique Strauss-Kahn Case and Your Investments

By Brett Arends

There are some simple lessons from all this. The Dominique Strauss-Kahn case hammers them home.

We should never assume the crowd, or "everyone else," or the market is right or even rational. Five hundred ill-informed opinions don’t amount to a hill of beans.

We should always listen to what contrarians have to say especially when they sound most ridiculous, and especially when they are being shouted down. We should never trust any judgments reached quickly.

In reaching our own conclusions, we should fight the urge to join the crowd. We should take our time, do our own homework and make up our own minds. There is no hurry.

We should always be willing to change our minds if need be. This is the hardest thing to do. We constantly have to remind ourselves that we could be wrong.

A MONKEY ECONOMY AS IRRATIONAL AS OURS

Smiling Chimp

As markets have evolved over time and financial theories have progressed humans have become increasingly confident in the systems we create and the world we live in.  Entire generations of investors have become convinced that markets are stable and efficient. We have come to believe that computer models can accurately predict markets.  On the contrary I believe most of the systems we create are highly complex, inefficient and chaotic.  The markets are one of the last refuges of natural selection (see here):

“The investment world is the civilized version of natural selection. It cuts to the core of every emotion imaginable.  When Joe Schmo goes to work for 25 years straight in an attempt to create a better life for his family and suddenly sees his life’s savings going down the tube because Lehman Bros went bankrupt you can’t possibly expect him to react rationally in such an environment.  This is no different than the man whose family is attacked in the middle of the night.  Do you expect that man to react rationally when everything he lives for is suddenly in harms way?  Do human beings make rational and efficient decisions in chaotic scenarios?  Even more important, will 1 million humans working in tandem make efficient decisions all within the same system?  No, the majority of them will make highly inefficient decisions.  “Mistakes” as we like to call them.   We all make them.

If we have learned anything over the course of the greatest mean reversion in stock market history over the last 24 months it is that markets are HIGHLY inefficient.  Why? Because the humans that write the algorithms are using flawed theories and the emotions upon which these trades are placed are not psychologically efficient.”

Despite our evolutionary leaps and bounds I believe we are not so far removed from our animal brethren when it comes to survival instincts. When confronted with complex decisions we make mistakes, we panic, we turn to our animal instincts which scream: SURVIVE AT ANY COST.  And nowhere is this more apparent than it is in the most complex facets of our lives.  Markets are highly complex systems and have become directly tied to important facets of our lives.  In many regards it is the last place most human beings should be residing. …

Scientific Proof That High Frequency Trading Induces Adverse Changes In Market Microstructure And Dynamics, And Puts Market Fairness Under Question

Scientific Proof That High Frequency Trading Induces Adverse Changes In Market Microstructure And Dynamics, And Puts Market Fairness Under Question

Courtesy of Tyler Durden

Up until recently, any debate between proponents and opponents of High Frequency Trading would typically be represented by heated debates of high conviction on either side, with discussions rapidly deteriorating into ad hominem attacks and the producer screaming ‘cut to commercial’ to prevent fistfights. Luckily, all this is about to change. In a research paper by Reginald Smith of the Bouchet Franklin Institute in Rochester titled "Is high-frequency trading inducing changes in market microstructure and dynamics?" the author finds that he "can clearly demonstrate that HFT is having an increasingly large impact on the microstructure of equity trading dynamics. Traded value, and by extension trading volume, fluctuations are starting to show self-similarity at increasingly shorter timescales. Values which were once only present on the orders of several hours or days are now commonplace in the timescale of  seconds or minutes. It is important that the trading algorithms of HFT traders, as well as those who seek to understand, improve, or regulate HFT realize that the overall structure of trading is influenced in a measurable manner by HFT and that Gaussian noise  models of short term trading volume fluctuations likely are increasingly inapplicable."

In other words, the author finds ample evidence that during the past decade (on the NASDAQ) and especially since the 2005 revision of Reg NMS (on the NYSE), stock trading increasingly demonstrates "self similar" fractal patterns, resulting in volatility surges, recursive feedback loops, and a market structure which is increasingly becoming a product of the actual trading mechanism. In the process, as demonstrated by a Hurst Exponent gravitating increasingly further away from 0.5 (i.e., Brown Noise territory), the Markov Process nature of stock trading is put under question, and thus the whole premise of an efficient market has to be reevaluated. Simply said: HFT has been shown to affect the fairness of trading.

The paper is, needless to say, a must read for everyone who has an even passing interest in stock trading and market regulation (alas, yes, that would mean the SEC, and Congress). And while one of the key qualities of the paper is presenting the history and implications of High Frequency Trading, and its rise to market dominance primarily as a result of the revision…

THE UNCORRELATED RETURN MYTH?

THE UNCORRELATED RETURN MYTH?

Courtesy of The Pragmatic Capitalist

Dragon painting

I came across this interesting paper (which can be found in its entirety below) the other day, while perusing Paul Kedrosky’s website, regarding uncorrelated returns.  The basic premise of the paper was that there is no such thing as uncorrelated assets. The author conveniently cherry picks the last 36 months to prove his point. Of course the last 36 months can easily be described as unique if not an outlier. Many have been quick to come to the conclusion that the last 36 months not only disprove the efficient market hypothesis, but also disprove the theory of uncorrelated assets.  This is highly flawed in my opinion.

Let me begin to dissect this issue from the beginning (without getting bogged down in too much mundane theory).  Anyone who is a regular reader has likely taken the time to read the “about us” section on the site.  If so, you know that my investment theories aren’t just some cookie cutter “fill the  Morningstar box” approach.  I believe the efficient market hypothesis is one of the greatest tricks ever played on the investment community.  Any market is nothing more than the summation of the decisions of its participants.   Markets, by definition are highly complex dynamic systems that are susceptible to chaos.  To assume that the summation of these decisions is somehow efficient would mean that the decision makers as a whole are efficient.   While this might be true to some extent, human beings (and even the algorithms written by humans) are guaranteed to be inefficient decision makers in a chaotic system.

The investment world is the civilized version of natural selection.  It cuts to the core of every emotion imaginable.  When Joe Schmo goes to work for 25 years straight in an attempt to create a better life for his family and suddenly sees his life’s savings going down the tube because Lehman Bros went bankrupt you can’t possibly expect him to react rationally in such an environment.  This is no different than the man whose family is attacked in the middle of the night.  Do you expect that man to react rationally when everything he lives for is suddenly in harms way? Do human beings make rational and efficient decisions in chaotic scenarios? Even more important, will 1 million humans working…

The environment has been changing but it’s only really become part of the investor consciousness within the last two weeks: Suddenly, cash has a cost. Money isn’t free. Not every business model makes sense. Not every hurdle for investment is sitting an inch or so off the ground.

It’s this normalization of interest rates which, despite it being in effect for three years now, that has all of a sudden gotten some attention.

Stock Market Crash Deja Vu? Keep An Eye On This Pattern!

Courtesy of Chris Kimble.

Just over 3 weeks ago, I shared a chart looking at the divergence that has been brewing under the surface of the S&P 500 (NYSEARCA:SPY). Since that post, the S&P 500 finds itself in a deep pullback, with other key stock market indices hitting correction territory at their lows.

Today we provide another look at the divergence and highlight why it’s time for investors to pay closer attention. In the chart below, we compare today’s setup to 2000 and 2007 and the market crashes that followed.  Note, though, that we have NOT broken trend support yet.

Similar to today, in 2000 and 2007 the S&P 500 made a...

The Vilas Fund, LP letter for the third quarter ended September 30, 2018; titled, “A Bull Market in Bearish Forecasts.”

Ever since the financial crisis, there has been a huge fascination with predictions of the next “big crash” right around the next corner. Whether it is Greece, Italy, Chinese debt, the “overvalued” stock market, the Shiller Ratio, Puerto Rico, underfunded pensions in Illinois and New Jersey, the Fed (both for QE a few years ago and now for removing QE), rising interest rates, Federal budget deficits, peaking profit margins, etc...

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
