Dancing with the Trend

Markets do Trend!

For the last couple of decades, I have classified myself as a trend follower.  Mind you, this is not market timing.  Market timing involves guessing at tops and bottoms.  A trend follower will NEVER get in at the bottom or out at the top.  It depends on how quickly his/her trend measures identify a trend that determines when to go long after a bottom and exit after a top.  I need to quickly clarify that I do not participate in the downside, only long positions, with cash being such a position in down markets.  Why double the risk of whipsaws?


Let’s first talk about some things about the market that I see misunderstood by many.  One is the frequent mention that is often heard in the financial media that when the market is up they say there are more buyers than sellers and when it is down they say there are more sellers than buyers.  This is total nonsense and a clear message that they do not understand how the secondary market works.  The secondary market is the market that you trade in, whereas, the primary market is capital raising through IPOs and secondary offerings.  They call them secondary offerings just to help confuse you.  Let me explain this more buyers than seller nonsense.

When you buy a stock, I assume most of you believe that it is bought with the hope of selling it sometime in the future at a higher price; sometimes referred to as the greater fool theory.  Not a bad idea.  Someone had to sell you that stock.  There is no stock sitting on a shelf somewhere.  You might assume also that whomever sells you the stock might have an opposite view about the future of that stock.  This may be true, but in reality, you have no idea why the stock was sold to you or who sold it.  They might have already made a nice gain in it and you are their greater fool.  The bottom line is that it is an auction market made up of buyers and sellers and in effect a zero-sum game.  A proper way to describe an up market would be to say there is more buying enthusiasm than selling enthusiasm.  Markets trend because as it moves up, buyers understand they will have to bid more for the stock and sellers know they can ask more for it.  This continues until that supply and demand event dissipates.  This is also the real beauty of technical analysis as that price is an instantaneous view of supply and demand.

Another comment from the media, gurus, experts, etc. is the comment that there is cash on the sidelines.  Absolutely total nonsense!  While an individual or institution can move to cash, they can only do so if someone buys their stock, so the blanket statement that investors are moving to or holding cash is wrong.  What would be important is to know WHO is going to cash, but again that is difficult to find out.  If you watch financial television pay attention to how many make these foolish comments.  And then ask yourself, if they have that misconception of the how the market works, what else is it they say that is wrong.  Eventually, you will turn off the noise.

Okay, back to trend following.  If you are going to be a trend follower, the first thing you must decide is what the minimum length trend you want to follow is.  Often, I see this important first step ignored.  I do not know how one can create indicators or set indicator parameters without answering this critical first step.  Maybe they just say they are trend followers just to be cool and don’t actually trade.  Let’s say you want to invest based upon daily data and trade only once or twice per month.  There are an average of 21 trading days each month, so you would set the parameters on your trend indicators in the 15 to 18 period range, or anyway that is how I would do it.  So, let’s walk through a scenario, the market starts to rise and after a week or so your trend measures start to pick it up and you begin to commit assets to the market.  I’m not going to get into the money management of this process as it has been covered in my “Building a Rules-Based Trend Following Model” series of articles.  The market continues to rise, you are invested; so, what tells you when to get out?  Either you use trailing stops, or you let your trend measures determine it.  Stops will generally get you out sooner but often can result in whipsaws, which however are usually not as painful as waiting for your trend measures to reverse.  These rules come under the money management process.

There is an additional element to trend following that is often ignored and that is trend duration.  How long does a market remain in an uptrend?  What determines that?  There are many ways to do this, but I prefer to use a simple process.  If a market is in an uptrend, then it is considered an uptrend as long as there are no pullbacks greater than a certain percentage, in my case about 6 percent.  The opposite is true for down trends, but again, I’m long only.  In my book, Investing with the Trend,” I beat this concept to death.  So, let’s review.  A trend, once in place, as determined by your trend measures, will remain in place as long as there is not a pullback greater than X percentage (6% for me).  We have now covered the philosophical aspect of trend following, putting it into action is a completely different subject. Chart A shows the Nasdaq Composite and the 6% trend length (zig-zag).  You can see that the 2016-17 rise lasted from July 2016 to January 2018 without a 6% pullback.

Chart A

Chart B shows the Nasdaq Composite with up and down 6% or greater trends back to 1982.  There have been many good tradable trends since 1970; often in the 150-day in length area.  A trend that lasts 150 days is a really good trend; that is about 7 months.  You can see how the giant up trend since the summer of 2016 fairs in comparison.  The last time was from the end of 1975 until mid- 1977.

This type of analysis can also help you determine which markets to trade as a trend follower and which to avoid.  One can easily look at a chart of any issue and probably see whether it trends or not.   Hopefully I have whetted your appetite to do your own research into trend analysis.  You will find that the learning process is rewarding and if you come up with something that seems to work well, it will be much easier for you to trade it, instead of using someone else’s work.  Isaac Newton was a trend follower.

Thanks to those who have served in our military.  Happy Independence Day!
