what an interesting week

From the onset, let me say that I sure wish the volatility in the market would subside. I find myself tracking at either 2(ATR) or sometimes 3(ATR), which gives me the willys, for lack of a better term. Of course, the volatility is a double edged sword, if you are on the right side of the trade and the market accelerates, as it so often does, you get the momentary feeling that you are a genius. That illusion can easily dispelled on the very next trade however, and you can end up feeling just as foolish as you felt smart…all within five minutes.

And some rationality in the market might be nice, too. Granted, a new Treasury Secretary might turn out to be a wonderful thing. but his options are as limited as the current Treasury Secretary’s. We have the accelerator on interests pushed nearly to the firewall, and the next step will surely be a Fed. Funds rate of 0%, ala Japan for a good part of the last decade. For all the worry about inflation we have heard, I find myself much more concerned with deflation and demand destruction, which causes all sorts of problems in balancing money supply, interest rates and a host of other more subtle problems. The point is, the problems that were sending the market downward Friday morning did not change with the potential appointment of a new Treasury Secretary, regardless of how talented the man is…we have some serious problems at hand and no real remedy in sight.

And the credit problems are really what has been giving the market indigestion, if not a downright ulcer. The numbers on the CSO’s and accompanying credit default swaps are just plain staggering, and solution is not apparent to even the most gifted economists. My favorite economist, Paul Krugman, has a number of suggestions, but I have yet to see a solution. We are in a situation of treating the symptoms of the disease but are, so far, unable to cure the root problem. And I’m not so sure throwing a pile of money at the problem is the answer….but maybe it is.

That being said, we also find outselves bailing out just about every industry that is in any way related to finances….the automakers being the most prominent. The most important question that has to be asked is fairly simple….”are we chasing bad money with good money?” I don’t have a credible answer to the question either. And then there is real estate, and mortgages, and taxes….the problems are manifold with all the participants lining up to get a piece of the government hand out programs. Where does it end? I don’t know, nor does anyone else….but the implications for the entire scenario appear to be grave, and the patient is very ill.

There is some beauty in it all, though. As traders, we always have the chance to earn money, we always have a job. Just the same, I worry about our country and the direction we have taken in the last eight years. I pray we can find our way back home and rest on solid footing. What do you think?

Fundamental traders have no extra time for the technical traders, and technical traders battle with the Efficient Market rabble, who constitute the vast majority of market theoreticians, for coherent interpretation of the unruly and unpredictable beast we refer to as “the market”. Of course, reams of academically-sound market studies proclaim the inherent correctness of the Efficient Market Theory. Why…no less than the eminent Dr. Burton Malkiel trumpets the sheer futility in considering anything short of Efficient Market Theory. No, one cannot argue with facts laid bare in slick PowerPoint presentations with glossy charts and multi-colored tables, that’s for sure, and yet there is something missing, something so essentially important that no theorist dare utter the words...equity market theory seldom translates into profitable trading.

And that’s a real problem for me. If a market theory is irrefutably true on paper it ought to have some phenomenal performance in practice. Of course, this is seldom the case.

For those who might have missed it, we’ve put a team of astronauts on the moon. We have unravelled the the vagaries of the quantum mechanics with startling accuracy, and teased the destructive power of atomic structure to produce enough nuclear weapons to obliterate ourselves tenfold. Why, we have even sequenced the double helix structure of of our own DNA
molecule. We are talking about the very building block upon which life is based, a structure so complex that literally billions, not millions, but billions of gene strands comprise it’s makeup.

But we have failed miserably at predicting where the market is going to move at a given point in time.

Yet we argue on as to who is right and who is wrong. It seems to me that I learned in my college Argumentation class that something true at face value, and provide proofs to that end, before you can argue your point. So it would seem a bit imprudent to argue about which theory holds true when we have proven to ourselves, over and over, that no theory has predicted, with any accuracy, where the market is going to be at a given point in time.

My one-watt brain cell demands that a FACT has to hold up time after time to be true. One cannot argue the untrue into truth. For example, these are facts:

  • 1+1=2 (unless you’ve digested Liebnitz’s arguments)
  • The moon revolves around the earth in a given arc and is not made out of cheese.
  • George Bush is the President of the United States.
  • We will all die

I think you get my point here. It is impossible to argue untruth into truth through a sheer volume of words. So I’ve managed in 21 years of trading at the institutional and retail level to establish only one irrefutable FACT

  • We have an incomplete knowledge base about the market and there is not a method to predict, with 100% accuracy, what the market is going to be valued at a given point in time.

Which leaves me out there with the lunatic fringe scratching my head in bewilderment. Yet I am a consistently profitable trader. I live in the very uncertain world of fractals, strange attractors and chaos theory. Yes, you heard me say it….CHAOS THEORY

The real problem with all market theories, in my opinion. is that they are linear in nature. Of course, even a cursory observation of any equity chart exposes the distinct non-linear pattern typical of the equity markets. It is not possible to predict even from bar to bar where he market is headed. No, a binary outcome is after each bar is the best you can hope for. That is to say there is a probability from bar to bar whether the market will go up or down or stay the same. And when trading, probabilities are the best we can hope for…and careful observation of market fractal mini-structures can be teased from the charts. Which is not to say that fractal structures are the Holy Grail in trading, but they are reliable predictors in non-dynamic markets….that is, markets unaffected by catastrophic or peculiar outside occurrences.

Of course, this type of thinking turns the world inside out….after all, we linear thinkers and are programmed to see patterns in the world and formulate patterns based upon observation. I am 5’7″ and weight 210 pounds and have gray hair. My boss is also 5’7″ and weighs 210 pounds, and yes…he has gray hair. So it stands to reason that 5’7″ and 210 pound men must all have gray hair. Of course, that is a simplistic view of our linear thinking process, but it serves it’s purpose well enough…and that is correlating variables of an infinite set is, at best, a dicey endeavor.

No, I’ve learned that the secret to the market lies in thinking in a non-linear fashion, and blocking out what seem to be obvious correlations. There are no obvious correlations in a non linear world….only fractals. Are you with me?
