Seeing The Gorillas in the Middle of the Market

Laurence Gonzales, in his fascinating book "Deep Survival: Who Lives, Who Dies, and Why", describes a research study from Harvard psychologists. They showed people a film of basketball players passing the ball to each other. During the film, a man in a gorilla costume walks into the middle of the action and stays visible on the screen for about five seconds. One group of subjects is asked to count the number of passes among the players; the other group is simply asked to watch the film. Incredibly, 56% of the subjects who count the passes don't ever see the gorilla. Of course, everyone asked to simply watch the film notices the gorilla man on the basketball court.

The point is that the brain is a kind of search engine: a Googler of reality. If we program our search to look for passes among basketball players, that's the output we receive from the brain. What is extraneous to our search (gorillas) is eliminated. When we conduct a broad search, we receive a wider range of outputs. Focused searches work well if we're looking for a specific item, such as lost car keys. They don't work so well when we need to process all of the information needed to survive in an environment of risk and uncertainty.

It is very easy to approach the markets in focused search mode. We develop a hypothesis about the market (bullish or bearish) and we prime ourselves to look for certain chart patterns or indicator readings. In our haste to find what we're looking for, we can miss the gorillas in the middle of the market. Afterwords, we might look back on market action and think, "How in the *&#@ could I have missed that??!!"

Gonzales writes, "The practice of Zen teaches that it is impossible to add anything more to a cup that is already full. If you pour in more tea, it simply spills over and is wasted. The same is true of the mind. A closed attitude, an attitude that says, 'I already know', may cause you to miss important information. Zen teaches openness. Survival instructors refer to that quality of openness as 'humility'. In my experience, elite performers, such as high-angle rescue professionals, who risk their lives to save others, have an exceptional balance of boldness and humility..." (p. 91).

There is a concise formula for trading success: boldness and humility. The boldness to act on what you see with the conviction, and the humility to realize that what you see may not be all that is there.

Notice how so many of the excellent market bloggers--Charles Kirk and Trader Mike come readily to mind--track a variety of sectors and indices, examining the market from multiple angles. They're not just looking for the passes on the basketball court; they want to make sure they're not missing any gorillas in the picture.

It's those gorillas in the middle of the market that we don't see that can catch us when we're lacking Gonzales' humility.

Oh, and by the way, did you know that, in yesterday's market, 917 stocks trading above $10 a share made 20-day highs and only 258 made new lows? But, among stocks trading under $10 a share, 199 made new 20-day highs and 241 made new lows.

How easy it is to miss those gorillas.

I didn't know that but I did know that my method of tracking 20 day highs (which includes a volume component to weed out the spikes) shows 761 new 20 day highs and 254 20 day lows. And my historical analysis says that anytime either one is greater than 500 the market will go the other way shortly.

And the reason is equilibrium as best expressed by buy low and sell high. When there are more opportunities to sell guess what - folks sell. (Or maybe institutions sell I don't think "folks" understand the concept yet). I think that is human nature - regardless of whether they "saw" the gorilla in the room it was there and they "felt" it. It would be interesting to know how many get the number of passes correct when the gorilla is in the picture as when it is not - bet there's a difference.

Hi John,

Thanks for your observations. I have consistently found that modeling short term moves in the market using price change and new highs/lows as variables has led to worthwhile market tendencies.

Sorry to see that you picked 2 Blogs that by my standard are not very good examples to explain your point of view - on the contrary they have a very good track record as contrary indicators.

Hi Ceasar,

If Trader Mike or The Kirk Report have been wrong on market calls, that would not diminish my point. What they're doing is taking a look at the entire market, not just the narrow slice they might be trading at the time. They're also clearly reflecting on what they--and the market--are doing, which leads me to believe that they have a real shot to learn from whatever mistakes they make.

I'm looking at trading as process, because so often I've found that success follows once traders get the process right.

And it may well be that all of us bloggers will be contrary indicators of sorts! The weekly polls taken by Ticker Sense might answer that issue. In the end, there's a lot of room between what our stated opinions are between market hours and how we actually trade when the markets are open.

Thanks for your note--

Brett
