Some Pointers on Passive Investment in the
World Market Portfolio

This article
follows up on my previous
article. It clarifies some questions and provides more specifics.
My goal is, at low cost, to get the average investor into a reasonably
sensible investing ballpark. In my view, investors should not be
spending very much of their capital paying for portfolio construction
or portfolio management services. I have two reasons for saying
this. One is that a do-it-yourself approach is feasible. There are
many index funds that are easy to buy and sell on exchanges as ETFs
using a good discount broker, like Scottrade, or through no-load
mutual funds. Second, the fees that many portfolio management services
charge are too high. The market bears it because many investors
lack financial knowledge.
Investors vary
in age, income, occupation, tax status, risk preference, and other
personal variables. There is no one investment solution suitable
for everyone. But, with adjustment to one’s cash position, one portfolio
of risky securities can serve surprisingly well to achieve the investment
goals of preserving capital, obtaining some growth of capital, and
keeping risk to a minimum. That portfolio is the world market-value
weighted portfolio.
Suppose W is
this world portfolio. Suppose you have money to invest, say $1,000.
You can vary the risk of your portfolio by what fraction you place
in W and what you keep in short-term liquid securities like treasury
bills or a bank account. A risk-tolerant person might place $1,000
in W and none in t-bills. A person more risk-averse might place
$500 in each. The fact is, however, that W has rather low risk.
Many people will want to invest most of their investable funds in
it.
The proportions
that the values of major asset classes have within the world portfolio
are suitable for a passive investor to mimic. The world’s many investors
have an immense amount of information that you and I do not have.
If they think that all the stocks in the world should have twice
the value of all the bonds in the world, as shown by their market
values, then so should we. We should hold twice as much money in
stocks as in bonds. If we don’t, we are betting (speculating) against
the market and saying that the world is wrong. If we hold all bonds,
we are implicitly denying that stocks are worth what the world says.
The world market
portfolio is likely to be of moderate risk, and the return it might
provide of 7 percent will seem too low for some. But it will provide
the highest return for that level of risk that one is likely to
find. One can place a greater amount of funds into it to make up
for the moderate return. Over time, one will be able to stomach
placing a greater fraction of one’s wealth in the portfolio because
the fluctuations won’t be as large as if one held all stocks.
Some will want
to go for the 9 percent or more that stocks may deliver.
Someone asked me why they shouldn’t just hold all stocks and no
bonds if they had a long investing horizon, because stocks tend
to outperform bonds once the horizon is 20 years or more. The answer
is that this is feasible, but it has added risk because one is undiversifying.
It is a form of speculation. The fact that stocks have made 9 percent
or more in the past and outperformed bonds doesn’t mean they will
do it in the future. In fact, bonds did as well as stocks in the
80s and 90s as interest rates fell. You could place all your money
in stocks and be making 9 percent for many years. Then suddenly
you could run into that rare occasion when stocks decline by 90
percent and then do not recover for 20 years. Stocks are risky.
If you place all your eggs in the stock basket, you are speculating.
And then you’d better know the principles of speculation. I have
nothing against speculation. I speculate. Most of us will do some
speculation. I suggest keeping one’s speculations separate from
one’s passive investments. Management of them requires very different
knowledge and principles.
Now, debt.
If you want to build up wealth through investment, you must postpone
consumption. You must avoid going into debt to finance consumption.
$1,000 invested at 7% doubles in about 10 years. If you are 20 years
old, $1,000 invested now could become about $16,000 by age 60 or
so. If you borrow to buy something, not only will you not see that
$16,000, but you will be paying someone else interest. Your wealth
will not only not grow, you will be enduring something akin to slavery.
You will have sold off the rights to your future income from working.
You will have to work simply to pay the debt and interest on the
debt. You will lose control over your income and wealth. That is
the price you pay for borrowing to consume now.
When I speak
of real estate investment, I most definitely do not mean your home.
You should not consider your home as an investment no matter how
economists define the term. It’s better to think of it as a consumption
item. You are buying a bundle of future housing services when you
buy a home. Any price change in it is incidental. Sure, there are
people who speculate on houses. There are people who buy them, fix
them up, and sell them. There are people who buy land lots and speculate.
People do lots of things. Let them. Unless you intend to specialize
in homes as a speculative business, forget it as an investment.
A home usually requires a mortgage, so you are in debt. It requires
tax payments and maintenance. Buying and selling it is very costly.
A home eats money. This is not what you want in an investment.
By real estate,
I mean commercial real estate. This includes such things as office
buildings, warehouse and commercial space, malls, and apartment
rentals. It means that you are the landlord. You collect the rents.
Now, you are not going to do this yourself. You will do it by buying
shares in companies that own and manage commercial properties. A
few decades ago, this market began to open up to individual investors,
but the arrangements were quite bad. There were limited partnerships
governed by horrendously long and complex agreements. Many investors
got burned. Today, the real estate investment trusts provide a stock
investment that serves the purpose.
By bonds, I
mean corporate bonds. I do not include government bonds in the market
portfolio. The market portfolio contains securities behind which
are real assets that produce income. Behind corporate bonds are
the company assets, which provide net wealth. Behind government
bonds are future tax payments that come out of taxpayer income.
There is no net wealth in these bonds.
It is difficult
to submit to the market’s pricing and not have a speculative view
of our own. One might be reluctant to place funds in bonds if interest
rates are low. But if one avoids bonds, one is betting on a rise
in interest rates over some period of time that will make capital
losses offset the interest income. This again is speculation. If
you have strong views about the pricing of some sector and you still
want to hold the world portfolio, consider phasing in your investment
over time. If you think bonds are too high in price, select some
horizon, like 1218 months. Then gradually buy into the bond
market. You will be mixing in a moderate amount of speculation into
your investment decision. This may satisfy your urge to act upon
your own views.
The world portfolio
involves a global asset allocation. Investment results hinge primarily
on the asset allocation proportions. Managers that advertise tactical
asset allocation are speculating on the pricing of various sectors.
Passive investment avoids this. Its asset allocation depends on
the market value weights.
I have two
different methods to estimate market value weights. Both are rough,
but they come out close. If the numbers do not all add up, don’t
worry about it. I’ve had several classes look into this over the
years, and the results always come out about the same. They are
approximate, but good enough for practical purposes. We are not
sending a rocket to the moon here.
First, for
high
net worth investors, who hold most of the world’s wealth, these
weights in risky securities (disregarding cash assets) are about
as follows:
- 35 percent
in stocks
- 24 percent
in bonds
- 18 percent
in real estate
- 23 percent
in other assets
The other assets
include all sorts of real assets like gold, timber, art, and commodities.
They include foreign currencies, hedge funds, venture capital, private
equity, and managed funds. The average investor will not be concerned
with many of these things, but we reserve some allocation for real
assets below. If and when these assets prove themselves and can
be bought by individual investors at a reasonable fee and if they
are diversified, then some part of the portfolio could be allocated
to them.
The second
method uses all sorts of estimates. The amount of real estate in
the market portfolio is unknown. By one
estimate, there is $14.5 trillion in commercial properties available
for investment. One-third is in the U.S. and two-thirds overseas.
By other estimates,
bonds are worth $45 trillion. Non-government bonds are worth some
$32 trillion and stocks worth about $35 trillion. The S&P 500
is worth about $15 trillion. One estimate
places world investable wealth at $123 trillion (including government
debt). Foreign debt securities are about equal in value to U.S.
domestic debt securities. The U.S. stock market, if it is worth
$20 trillion in total, would be 20/55 = 0.36 or 36 percent of the
world total.
Starting from
$123 trillion, subtract $13 trillion for government bonds. That
leaves $110 trillion, of which $32 trillion is bonds, $35 trillion
stocks, and $43 trillion is other, mainly real estate. The proportions
are
- 32 percent
stocks
- 29 percent
bonds
- 39 percent
real estate and other.
These numbers
are close to those found for high net worth investors. It’s not
worth getting too fussy about all this. If other real assets are
10 percent, that leaves 29 percent for real estate, which is $32
trillion. This is inconsistent with the one estimate of $14.5 trillion,
which I think is too low.
The precious
metals, art, timber, commodities and such are not as large as one
might think in contributing to overall world investable wealth.
Without going through an elaborate calculation, they add up to 10
percent at most. I allocate 10 percent. That is generous. One might
make it 5 percent.
Putting all
this together, I suggest these approximate proportions for the world
market portfolio.
- 35 percent
in stocks
- 25 percent
in bonds
- 30 percent
in real estate
- 10 percent
in gold
Then I suggest
dividing the bonds into half domestic and half foreign bonds. The
real estate may be divided into 1/3 domestic and 2/3 foreign. However,
I could not argue with a 50-50 split. The stocks can be divided
as 40 percent domestic and 60 percent foreign, based on estimates
above.
We then have
- 14 percent
U.S. stocks
- 21 percent
foreign stocks
- 12.5 percent
U.S. bonds
- 12.5 percent
foreign bonds
- 10 percent
U.S. real estate
- 20 percent
foreign real estate
- 10 percent
gold
This portfolio
definitely avoids the "home bias" that is typical of many
investors who stick too heavily to their own countries. Furthermore,
it leans toward the faster growing and less socialistically constrained
corners of the globe.
The next step
is to choose mutual funds for these categories. I can do that in
many ways. Whatever selections I might make will be merely suggestive.
I have not done a thorough study of all the available indexes and
what they contain. I haven’t broken down the above classes into
finer categories. There is a great deal I have not done. It’s not
clear that it pays to do a great deal more. This is where you can
do your homework. You also can subdivide some of the categories
still further if you like. My job is done. I have shown you what
the passive investing ball game is about.
For U.S. stocks,
there is VTSMX, Vanguard’s total stock market index. Also look for
their exchange-traded fund that may avoid some costs, which is VTI.
For foreign
stocks, there is VGTSX, Vanguard’s total international stock index.
See also their VEU.
For U.S. bonds,
a mix of maturities is best or else a duration of about 5 years.
One may wish to avoid bond funds that have mortgage-backed securities
and stick with traditional bonds. One may wish to avoid high-yield
bond funds. Keep it simple. One might want tax-exempt bonds. Many
bond funds contain government bonds. This won’t matter much. The
fund VBMFX is a possible choice. Also see BIV.
For foreign
bond index funds, a possibility is EMB.
One might choose
RWR for domestic real estate and RWX for foreign real estate.
There are plenty
of advisors on how to hold gold. I make no suggestion.
In sum, with
about 6 mutual funds and/or ETFs in the proportions suggested, plus
a commitment in gold, one can attain an overall portfolio that will
be about as worry-free as one can make it. Not only has one diversified
very well across sectors and the world, but also within each fund
are hundreds and sometimes thousands of securities. Your bet is
on the world economy. You cannot make it any more basic than that.
You are not speculating on any individual sector, country, company,
or type of security. You are so well diversified that a catastrophe
in one area should leave you almost unscathed. If the world survives
and grows, you will earn a normal rate of return on your investment.
There
will be taxes to pay. This is very disturbing. Having paid taxes
on your income, you will then pay taxes on what you save. When you
die, there will be more taxes. You will wonder why you bothered
building up wealth. The government encourages us to be wastrels.
It’s a wonder that some of us still save. In America, the official
saving rate is zero or negative.
Perhaps your
best investment is in travel. You can find another place in the
world to live, one that doesn’t tax investments the way the U.S.A.
does.
