Unmasking the VooDoo: Trends

When discussing technical analysis and trends, the erudite snoots among us, which unfortunately can include me, like to talk about physics. Objects, or trends, in motion will stay in motion unless acted upon by an outside force. That's inertia and yes, markets have it. How else do we explain momentum stocks, let alone bubbles?

As the old Faberge Organics shampoo (with wheat germ oil and honey) commercial used to say, "If you tell two friends, then they'll tell two friends, and so on and so on and so on." The same goes for the markets. It's the ultimate expression of keeping up withe the Joneses. Everyone covets everyone else's profit-making assets

Trends exist because investor B wants in on the action of investor A. But why?

My reasoning is that trends exist because information flows around the market imperfectly. Some people get it sooner and others later. Some people act aggressively and some not at all. Eventually, everyone assimilates the information but guess what, the market is already way up by then. But that's another topic.

If not for this fact, stocks would only trade the bid-ask spread until the next news or earnings report. They would then jump or fall, in one fell swoop, to the next price level where they would trade around the new bid-ask. It is the imperfect flow of information, either lagging or leading when someone figures out the news before it is releases, that allows smooth trending.

Nowhere but in the financial and commodity markets do people want to buy more as the price goes higher. My economics 1a professor, Barney "guns and butter" Schwalberg would not approve. Yet, in the markets, the more people that want it, the higher the demand and higher the price, and (drum roll) the more other people want it.

Talk about FOMO!

With that said, there is still a bit of sanity left here. If prices rise too fast - and that is clearly subjective - then some people wake up and realize they should probably cash some of this windfall in. Supply increases and sure enough price action heads a bit lower.

This could happen a few times and the market establishes a sustainable trend with a velocity that makes sense for that market at that particular time in history.

Right now, Bitcoin merits an insanely steep trend. It's new and, as far as a concept can be, really shiny. Maybe next year, when $30 million simply vanishes as it did just this month in competing crypto-currency ethereum, we'll see the market's invisible hand show itself. 
Here is the headline "A coding error led to $30 million in ethereum being stolen." That is absolutely frightening, but I digress, as I always do.
The real question for most markets most of the time is what do you do with trends. The answer is, "ride them."

The next question is how you tell when they end. The answer is, "the market will tell you."

Huh? So they will ring a bell at the top? or the bottom?

Well, not exactly. It is durn near impossible (yeah, I speak hillbilly) to know when the peak or bottom in any market is happening as it happens. Chances are you will have to give up a bit before the signal becomes somewhat clear. But that's the whole point of stops. They let you ride the trend until it changes.

Now, you may have other constraints such as scaling out of a position after X% and Y% moves. Or maybe you see better opportunities in other markets in trends that are not quite so old. Or your funnymentals change. Whatever your reason, you decide to get out. But that does not mean the trend is over. Only the market knows that.

The old saw, "the trend is your friend" is absolutely, positively true. However, you cannot forget about the second part of that, "until the end."  How may people go broke NOT realizing the trend changed and they continue to BFTD? Can you say Internet bust?

Bonus thought: We usually like to lambast the little guy for being in the wrong place at the wrong time. It is the crux of COT (commitments of traders) analysis saying that when the little speculator gets massively long the bullish trend is about to end.

The thing is that the little guy is right during the meat of the trend. Elliott Wavers cleverly call that "wave 3." They may be slow at the start of the trend and overly enthused at the end but the middle of the trend needs the masses to really get going with size and power.

So, you still have to know a little bit about the trend you are in. Identifying that is more than half the battle when you make your buy, sell or hold decisions. Everything else is gravy.

Unmasking the VooDoo: Chart Patterns

If you are not a charting aficionado you might think that trying to predict future price movements from past price movements is pure folly. And guess what? You would be right.

What? Did I just say that? Well, yes I did but there is more to it than the simple answer. We cannot predict price movements but we can assign porbabilities to what might happen based on what already happened.

"What's the difference?" you ask.

It's a big difference. If you say you can predict what will happen you are gazing into an orbuculum. That's a crystal ball, for you lay folk.

What technical analysts do is gauge future possibilities based on the footprints the elephants leave in the butter. Here is the phrase that pays:

People tend to act in a similar manner when faced with similar situations.

Chart patterns are those similar situations. The "forecast" is the similar manner of action. Nowhere does it say "will" or "must." 

Let me pull a large quote from my favorite author with that phrase embedded.

"Chart patterns are formed by the buying and selling actions of people and people tend to act in a similar manner when faced with similar situations. Some blame this on a self-fulfilling prophecy: if enough investors believe in the significance of a chart pattern ending then they will act, and thus their actions will assure that the assumed result will occur. "

- A Beginner's Guide to Charting Financial Markets: A practical introduction to technical analysis for investors by Michael Kahn.

Wow, that guy makes sense!  Let's continue:

"But investors may not act the same way this time and the charts will tell us when that is the case quickly before losses begin to mount." 

That implies that technical analysis does not expect to be right all the time. If it did, then probabilities would be 100%.  Therefore, trying rate the efficacy of technical calls just by the success rate is a failed methodology.  I challenge you to show me the price/earnings ratio at which a buy signal will always result in profits. Or a percentage of orders or inventory that is 100% right when making a buy or sell call on a stock.

Any single technical analysis-based call can fail. However, string enough of them together with stop losses and re-evaluation at achieved price targets and the Cajun chef will ga-ron-tee a nice positive rate of return.  

What is a pattern, anyway?

Charts are just graphical representations of the tape. They show us how price changes over time and the forms they take actually do tell us a bit about what was going on in the market when they formed. Does the shape of an EKG tell the doctor about what is going on in your heart right now? And can the doctor then "predict" whether you will have heart issues in the future? 

Charts form based on the buying and selling actions of people. And, they really only have three flavors:
  1. They can be pauses for rest in an ongoing trend
  2. They can be pauses as the market decides it wants to go the other way
  3. They can be pauses when the market just has no clue which way it wants to go
Number 1 is called a continuation pattern. Number 2 is a reversal pattern. And number 3 can be a trading range or just a directionless market filled with either uncertainty or apathy.

Patterns have tops and bottoms and they are indeed called resistance and support. Typically, when prices move through one or the other the trend continues in that direction. Something happened to trigger a mood change from the rest or uncertainty of a pattern to the conviction and movement of a trend.

Fortunately, markets have inertia, just as in physics. If they are in motion (trending) they tend to stay in motion. And if they are at rest they tend to stay at rest - both until acted upon by a force.

That force can be truly from the outside, such as news, earnings and legal matters. Or it can be inside the market when sentiment changes or a related stock or index breaks out from a pattern. In either case, pattern becomes trend and it will stay that way until something makes trend turn into pattern.

How do patterns form?

I am not going to get into the nuances of all the things that happen in patterns with volume, momentum and the shapes of various patterns here. Those things give us additional clues as to which way the market can break out but they are not needed to understand just how a pattern forms.

When a pattern first starts to form, the trend hits an insurmountable speed bump. Keeping it simple with a rising trend, it pulls back, finds a new support and rallies again. But it is stopped at the top of the pattern, which now for the first time starts to actually appear. The cycle happens a few more times.

What is happening now is the bulls see a cheap price at the pattern bottom. The bears see an expensive price at the top. Both act accordingly. Nobody has enough nerve to do anything else.

In the case of a triangle or any other pattern with sloping tops of bottoms, the bulls tend to sell out earlier within the pattern. The bears tend to close shorts earlier. Uncertainty builds as neither side is willing to let the market move to their desired prices. They take action earlier and earlier.

Finally, one side finds a reason to push their agenda. For an upside breakout, the bulls no longer sell out at the pattern top. In fact, they buy more. And away we go!

Different pattern shapes are just theme and variation. It is the same dynamic going on in all of them. However, pattern shapes do give us more clues as the eventual resolution.


Chart patterns help us decide what to do based on subjective probabilities that the market will do something somewhat specific once the patterns are broken. The market does not do X just because it broke out. The pattern breaks because the market decided it was time to move. And it lets us know about how far it will go be the way it formed the pattern in the first place.

It is our job to read these signals and do one of the only three things we can do - buy, sell or hold. We do not know exactly where the market will go and how long it will take to get there. However, based on the signs, we will get a very good idea if we should ride that tiger with a lot of money or with a little or forget about it completely.

Nobody cares if you predicted a market target. Only your wallet cares that you made it fat.
