Whenever I
write on anything remotely connected to securities, people ask me
many questions. Why is M1 flat and gold rising? Should I follow
M1 or M2? Why did the Fed discontinue M3? When will the housing
market recover? What’s a good investment during a recession? They
are more than curious. They want to know what to do with their money.
I think that
most of these people are making a basic mistake. They are seeking
information in an attempt to speculate. I think they’d be better
off if they became passive investors and left the speculating to
speculators (or traders). Most traders lose money.
How should
one invest? The textbooks on investing run almost 1,000 pages. Such
a mass of material overwhelms and confuses many people. For example,
these texts distinguish between active and passive investing. They
use the term active investing to avoid using the term speculation.
But active investing, which is an attempt to beat the market, is
speculation. To my way of thinking, investment is passive investment.
This article
provides counsel on investing viewed solely as passive investing.
In this way, I answer many of those individuals whose queries I
have not answered. Naturally, no matter what I say, it will not
be enough.
Investment
and speculation in securities are two different things. They require
very different fundamental principles. One should not confuse them.
The investment
and speculation I discuss here both involve placing funds into securities
or asset-related securities. That is about all they have in common.
Speculation
is an attempt to profit, that is, earn an above-average rate of
return, by forecasting the future price movements of specific securities.
Investment aims for average returns without forecasting specific
price movements. It relies on general price movements. Speculation
typically involves moving in and out of securities based on the
evaluation of new information that is constantly occurring. The
time horizon may be anything from a few seconds to several years.
Investment positions are typically not altered simply because new
information has transpired, and the portfolio changes are likely
to be infrequent and related to basic matters such as portfolio
rebalancing, need for income, taxes, and risk preferences rather
than interpretations of new information. Speculation, even without
using borrowed funds which I am ignoring, involves greater risk
because the speculators typically concentrate their money in a few
securities. By contrast, investors diversify to reduce risk.
Speculation
is a business and a very difficult business. The number of people
who make a profit by starting and running businesses is relatively
small, especially in lines of business that are highly competitive.
Speculation is a highly competitive business. There are very few
highly successful people in any field of endeavor. The average person
who attempts to speculate is very likely to fail at it. Studies
of brokerage and commodity trading accounts show that upwards of
80 percent of traders who speculate lose money.
The reason
for this is that most amateur speculators do not follow sound fundamental
principles of speculation. They don’t know what these principles
are.
Engineers build
bridges (or should build bridges) based upon sound fundamental principles
of physics, engineering, geology, meteorology, geometry, and trigonometry,
to mention a few. Violin-makers craft violins (or should craft them)
based on sound fundamental principles, not all of which are in the
public domain. They include knowledge of acoustics, wood, aesthetics,
music theory, harmonics, and so on. What do economists do (or should
do)? They explain economic activity. Their explanations should be
based upon sound fundamental principles, such as the purposeful
behavior of individuals, choice among ends, and the scarcity of
time and means to achieve ends.
Similarly,
speculation and investment each has its own sound fundamental principles.
Buying a stock because it is low in price and selling a stock because
it is high in price is not a sound fundamental principle of speculation.
The reason is that a stock’s future price movements do not depend
on whether it is low or high in price. Low-priced stocks may just
as easily fall as rise in price, and the same goes for high-priced
stocks. Whatever the sound fundamental principles of speculation
are, they are based upon a knowledge of those factors that provide
an accurate guide to future stock price movements. Knowledge always
is the basis of true basic principles. You will not find revealed
here the fundamental principles of speculation. If you search for
them yourself, you will find many competing claims and little evidence
to back up most of them.
Warren Buffett
has sound principles. His wealth and success prove that. Is Warren
Buffett engaging in speculation, investment, or something else? Should
we look to what he does in order to find basic principles that we
can apply? Buffett is in large measure a businessman. He buys whole
companies after meeting the owners and managers. His holding company
has a structure for managing these purchased enterprises. This part
of Buffett’s procedure is not security investment. It is investing
in real assets. This is not our subject, which is investing in securities.
Buffett also
buys individual securities. His usual strategy is to buy first-rate
companies at prices that are at a discount to the values he perceives
them to have. Buffett concentrates wealth in a few of these securities
that he likes a great deal. This is a variant of what is called
value-investing, which I shall now argue is speculation.
There is disagreement
on sound fundamental principles of investment just as there is disagreement
on how to build violins. Many so-called investment strategies are
actually speculation. Consider value-investing. The investor seeks
securities whose prices appear to be relatively low compared to
some measure of value, such as book value or cash flow. The investor
must monitor many securities to determine the value measure for
each of them. As individual securities change in price, so do the
value measures. The investor then changes the portfolio over time
to maintain its value orientation. All of this requires monitoring,
assessing new information, a steady stream of buying and selling,
ongoing transaction costs, and taxes. These are the same kinds of
things one encounters when one speculates. Of course, there are
variants of value-investing in which the holding period is lengthy;
but that doesn’t matter much because the basic idea of value-investing
is speculative. One is forecasting that the value securities will
outperform other securities if and when the market recognizes their
value quickly and bids the prices back up so that the buyers get
an above-average return. But seeking profit is what speculation
is about. Speculators are not content with average returns. Another
speculative aspect of value-investing is that, in order to gain
the benefit, the buyers unbalance or concentrate their portfolios
in favor of the value securities. This adds risk to the procedure.
Value-investing is actually not investment. It is active investment,
which is speculation.
I am definitely
in a class of one to call value-investing speculation. One need
not be too concerned over this. Properly executed, value-investing
is a good way to speculate. My only reason for explaining it and
calling it speculation is to steer the average investors toward
passive investment and not let them detour to any of these alluring
side streets. If you insist on detours, then what you should do
is divide your money into two piles. One pile will be for passive
investment, the other for speculation. One will be for money you
do not want to lose, the other for money you can afford to lose.
Keep them absolutely separate and you will have fewer regrets. Mix
up the two and you will find yourself getting nowhere as the years
pass.
What then is
involved in investment? Various states-of-the-world can happen in
the future, in fact, an infinite number of possibilities. The investor
makes no effort to discern what these will be and which ones are
more likely to occur. He makes no attempt to speculate on the future.
The first sound fundamental principle of investment is not to speculate
in any way, shape, manner, or form. The investor swears off trying
to forecast the future. This means he pays no attention to the investment
markets, to changing prices, to the news, to economic data, to political
events, etc. He does not let any of those things influence his investment
policies. He will not be wasting his time trying to decipher M1,
M2, and MZM. He will not be Fed-watching. He will not be constantly
on edge about the markets. He will not constantly be in a state
of confusion wondering why stocks fell when he thinks they should
have risen.
The second
sound fundamental principle of investment is to buy and hold a value-weighted,
highly diversified or market portfolio. One may rebalance that portfolio
on occasion as new securities become available, but low turnover
will be a hallmark of a portfolio that is following sound fundamental
principles. Investing will be a boring sideline, requiring very
little of one’s time and effort. One will not be doing much buying
and selling, and this will keep both transactions costs and taxes
low. The effort will go into finding out what one’s asset allocation
should be, that is, finding appropriate value-weights and diversifying
properly. Diversifying properly means really diversifying.
This goes well beyond merely buying the major stock index of one’s
country.
Those two principles
are the main ones that you need to get you into the investment ball
game in good shape. A third sound fundamental principle is to start
investing as early in life as possible. This means saving and not
consuming. It means not going into debt.
If there is
one thing that the finance literature shows definitively, it is
that diversification pays. The gains of a portfolio rise relative
to the losses as one diversifies into more and more different kinds
of securities. This means that the average return rises compared
to the possible loss or risk, or the ratio of return to risk rises.
There is absolutely no question that diversification pays. To diversify
as broadly as possible, the idea is to hold the world market portfolio
of all securities. This is an unattainable ideal, but today’s mutual
and exchange-traded funds allow one to get close to this very quickly
and at very low cost. Today’s investment products are a tremendous
improvement over what was available 50 years ago.
You may disregard
those who laugh at diversification because it is merely average
investing. These giants of active investing all claim that by focusing
on a few well-chosen securities, they can do far better than average.
They are speculating, however. That is for your other pile of money,
the money that most people lose. The speculators who do not boast
do not let you inspect their sorry brokerage trading records.
How shall you
diversify? Very, very, very broadly; the more broadly the better.
There are many asset classes. The ones that provide most of the
market value are domestic securities, foreign securities, stocks,
bonds, real estate, and real assets. These are the mainstream investments.
Stay with them. There are some potentially attractive classes that
the average investor will find it difficult to get into, such as
venture capital. There are some securities that one should simply
avoid, like hedge funds. One may avoid abstruse derivative-based
securities.
I will explain
next the basic idea. It will seem foreign to some and complicated
to others. But, in the end, it is rather simple to accomplish a
highly diversified passive portfolio. With a few of the Vanguard
portfolios, for example, one can in a few minutes time own a portfolio
that has thousands of domestic stocks, thousands of foreign stocks,
thousands of bonds, gold and precious metals stocks, and participation
in hundreds of real estate investment trusts. One can then fine-tune
the process if one wants to hold gold as bullion or break down the
asset classes into finer sub-divisions.
The basic idea
is to buy a value-weighted market portfolio of these assets. The
reason for the value-weighting is as follows. There are many thousands
of securities that investors and speculators are valuing. Their
valuations are better than yours. They have more information and
more money that they are hazarding. You cannot possibly keep up
with all the new information and how it affects security values.
The market will sometimes be valuing various securities too richly
and others too poorly, but you don’t know which is which and neither
does the market. But it is doing the best that it can, and its valuations
are reflecting huge amounts of information that you have no access
to or knowledge of. The market’s valuations across all these securities
are more likely to be accurate than for any one security. If you
buy the entire market in value-weighted proportions, you will be
mimicking the actions of all investors collectively in all their
assessments, using all the available information. You cannot do
better than that if you tried. If you try, do so with your speculative
pile.
The reason
for the market portfolio is that it, by definition, includes every
existing security in the world. This gives the maximum diversification
and the maximum gain/loss ratio.
Suppose that
there are only three asset classes: bonds, stocks, and real estate.
If the market values all the bonds in the world at $50 trillion
and all the stocks in the world at $75 trillion and all the real
estate in the world at $125 trillion, those relative valuations
are likely to be as good as any can be, given the information packed
into them. In this case, the total value is $250 trillion. Then
one should place 50/250 = 20 percent of one’s funds in the bonds,
75/250 = 30 percent in the stocks, and 125/250 = 50 percent in the
real estate. Once that is accomplished, you will hardly ever have
to change the portfolio. No matter how the relative values change,
you will always be holding something close to the market portfolio.
When new assets come along or new ways to participate in the existing
assets, some re-allocations may be in order.
The problem
of passive investing comes down to determining appropriate market-value
weights and then determining appropriate securities that match the
asset classes. Obviously one cannot buy every single security everywhere,
so one must find index funds that mimic these assets. The passive
investor of today is extremely fortunate! There is an ample number
of exchange-traded and mutual funds that provide very low-cost access
to a portfolio that approximates the world value-weighted market
portfolio.
Harry Browne
in his little book Fail-Safe Investing explains and justifies
a similar passive investment approach. If it will make you feel
more comfortable, read his book. It will supplement what I am saying
even though it is saying different things. Browne ends up recommending
a four portfolio worry-less investment policy. He has equal proportions
in long-term bonds, short-term bonds, gold, and stocks.
No one knows,
including me, what the world market portfolio’s asset proportions
are. You can search the internet as well as I can. I believe that
the proportions are roughly 40 percent real estate, 25 percent bonds,
and 25 percent stocks. Gold and other real assets such as timber
may account for 510 percent of total assets at most. Hence, one
might think about a portfolio like 25 percent bonds, 25 percent
stocks, 40 percent real estate, and 10 percent gold. If one alters
these proportions, it will not make much difference.
The main idea
is to apply sound fundamental investment principles. They are: do
not speculate, and buy and hold a highly diversified value-weighted
portfolio. If one has 20 percent bonds, 30 percent stocks, 40 percent
real estate, and 10 percent gold, you will not fail the course.
Within the
relevant categories, one should diversify further. Suppose one has
30 percent stocks. Find out how much market value that American
stocks have compared to foreign stocks. Then adjust the portfolio
to those proportions. One might split the portfolio as 20 percent
American stocks and 10 percent foreign stocks. Similarly, one can
diversify the bond and real estate portions over domestic and international
securities.
This kind of
portfolio will be as worry-free as one can make it. It will have
the lowest risk for the highest return. In absolute terms, its return
will probably be something like 68 percent a year. The bond and
real estate portions will cause its return to be lower than if you
held an all-stock portfolio, but the risk will be a lot less. You
will not endure the sharp fluctuations that stocks quite often deliver.
The
risk of investing is not always easily observed until it is too
late and the investor discovers to his dismay, after his stocks
or bonds have fallen drastically, that his investment portfolio
was risky. I cannot too strongly stress that a highly diversified
portfolio of this kind has far lower risk than investing in any
single asset class and far, far lower risk than investing in a handful
of securities as speculators do. The goal of such a portfolio is
to preserve and grow capital, earning an average return, with a
minimum of risk.
