Introduction
If we were more
confident, we would commit. The lack of confidence is what prevents us to
committing to another person, a political view and an investment of time,
effort, or money. Animals as well as
humans over-rely on our or others' memory as a guide for our next committed
actions. The difference between humans and animals is that out of bitter experience
we have been disappointed that in particular cases the past was not repeated
exactly as believed.
To protect ourselves
from disappointment we search for systematic ways to predict the future. Often
not finding the magic formula, we rely on so-called "experts."
Another Lesson from
"The Track"
While at the track
after I concluded either I couldn't find the next winner or in my opinion the
betting odds were too low to make a sound bet, I began a life-long exercise. I
listened to those around me in their conversations as to why they thought a
particular choice was the correct one. In an over-simplification, these views
generally fell into two camps. The first very much focused on especially current
information about various horses, jockeys, trainers, times of prior winners,
and track conditions. The second camp used various numerical inputs such as
past speed records for the race, the weight the horse was carrying, whether
horses that were favorites that day were winning at the expected rate, etc, etc.
This second group was slavishly following a systematic procedure or as it was
known at the track, they had a system.
The post-race reactions after members of each camp that did not win was most instructive. First both blamed
various "experts" for not producing winners for them. Those in the
first camp restudied the information they had before the race to see what
critical insight that they missed that they should apply to future races. The second
camp’s followers rechecked their data for accuracy and if their math was
correct they would begin the search for a new system and a new set of
"experts."
The first camp were my
first exposure to the arts of analysis. They searched the very present
competitive conditions. The second group were in effect statisticians who
believed the future could be determined from the numbers.
Years later I
recognized that these two camps exist today in guessing which way various
elections will go and what is the most successful way to manage money.
Statisticians
As a career securities analyst
I have never seen a number from which I didn't want more information and data.
However, I am not a card carrying member of the statistical clan. The reason I
do not claim membership is that I do not think the numbers by themselves provide
the answers that I need to generate confidence.
There are two other
reasons that I don't wish to fit under the statistician label. The first is
historical. In the era when the Dow Jones Industrial Average was being
constructed, those hard working clerks in brokerage firms who produced
recommendations for investors and whose main source of corporate information
were the very thin reports published by companies. These clerks were unable to
visit companies or third party sources and were called statisticians. My guess is
that my Grandfather's firm had one or more. It was not until the era when
Benjamin Graham was going beyond the ratio analyses of annual reports that the
term securities analyst evolved.
The second reason I do
not want to march under the statistician banner goes further back in history,
but is equally important today. Another Benjamin, Benjamin Disraeli the Prime
Minister of the United Kingdom in the 19th century is quoted (most often in the
US by Mark Twain) as saying "Liars, Damn Liars, and Statisticians" were
the source of bad information and
conclusions. I am afraid, particularly this remains true in the political world
today. Part of this tarnished label attached to statisticians has to do with
polling. Not only did the Brexit polling not capture the true intentions of
those in Northern England but that it was followed in Colombia. There were
three pre-referendum polls that showed that the no vote in Colombia was between
34 and 38%. The final vote was the "No" vote carried 50.2%. Again the
issue has a geographic focus. Most of the No vote was largely rural, which is
more difficult and expensive to gather. I am guessing many of the current US
polls are similarly flawed.
One of the mistakes
some British made is crediting the bookies with analytical inputs. A similar
mistake, I believe, is being made on this side of the pond. The believers in
the efficacy of these inputs, do not understand that both measures are
similar to the pari-mutuel system at the racetracks where the odds are not
judged mentally but are calculated by the amount of money bet. Further, my
guess is that the northern English farmers and most Republicans in the US are
not by nature gamblers, so the weight of money is not representative of the
voters.
Turning to our
investment world, those that believe in factor investing or other asset
allocation dictates are essentially statisticians looking for their
"system" as some of their brethren did at the track. Recently JP
Morgan Asset Management published a 72 page
"Guide to the Markets®". An analysis of
some of its data is as follows:
It has identified seven major
factors; including High Dividend Yield, Small Cap, Minimum
Volatility, Cyclical Sectors, and Momentum. The two best factor portfolios in 2015 were
the last and next to last in the first nine months of this year.
Asset allocation funds may
have many adherents, however since 2006 in a performance array of ten different
types of Fixed Income funds on average they ranked fifth out of ten with two
years in fourth place and three in sixth place.
In a similar selection of
ten major asset classes from 2000, asset allocation returns were again in the middle
on average, with the best in one year getting up to third place and five times
in seventh place.
There is a problem with
the statistical-only approach. When will the creators of the factors or asset
classes recognize the changes in our dynamic markets? If those changes are
perceived too late, much of the growth in value will not be achieved. For
example, when the four largest global companies in terms of current market cap are
recognized with appropriate weights they are all relatively young companies
that are still in their first to third
generation of management. The
four are Apple, Alphabet (Google), Microsoft, and Amazon.
Analytical Approaches
A good analyst examines
the past statistics to see what items are likely to be absent going forward
and/or deserve a different weighting going forward because of a change of
conditions. In projecting the future it is also wise to assume some level of
intellectual or financial fraud as well as less than perfect executions of
plans. In addition one should expect that technology will both help and hurt
people's efforts. At one point, it was good analytical practice to calculate
eventual scrap value from written off plant and equipment. Today it may actually
cost a company to close down and get rid of plant and equipment without a
tangible scrap value. In today's fast moving world useful lives may be shorter
than the depreciation schedules.
Beyond the analysis of
the past what can the analyst use to project the future? To an important extent
demographics is destiny. However, the raw numbers have to be modified by
changes in social structure and education. The answers may be quite different
from work force and consumer market applications. These trends are not just
national but global in implications. In turn this suggests that any US investor
that does not have approximately half of his or her earnings coming from beyond our
borders is not appropriately hedged. However, we already live in a global world
where almost every company large or small is benefiting or suffering from
multi-national influences. Thus no matter where you pay your taxes, locally
based multi-nationals are diversifying the national sources of your investment
income without your instruction.
Investment Implications
One of the lessons from
the racetrack is that short races are more difficult to get right. The first
one out of the gate has a tremendous advantage over the slightly slower. In
investing I have noted a similar phenomenon. Catching up is difficult. Thus, at
the track and in terms of portfolio management I prefer the longer races where
there is time to recover. Therefore, at this point in our history I would like
to focus a couple years after the next series of US elections which may not end
until 2019. At that point demographics from today's level and mix will be
playing out. There will be some major technological changes, hopefully
positive.
I am more confident in
the run up to my preferred investment horizon, I will rely on the past pattern
of periodic and relatively painful declines followed by much longer
periods of gains which in total produce a reasonable rate of return for those
who are in for the long-term. This philosophy will work until it becomes
dangerous because of “fellow travelers’ enthusiasm.”
