The Nature of Markets
Globalization, the trade of
natural resources, labor, and capital around the world, is a universalizing
force. Economics is the study of universally rational human behavior. But
economic logic, the study of equilibrium, requires no markets. The following
essay introduces the reality of markets into the investment discussion and
discusses navigating the 2008 environment.
Take for instance the simple
economic tradeoff between two goods, in this case the classic consumer tradeoff
between wine and bread. Behind this simple graph are significant assumptions
about rational human behavior:
The neoclassical theory of choice assumes that a consumer
has full information on every product and its effect on his welfare. In other
words, he knows the world and himself perfectly.
A consumer is able to calculate an ordinal measure of his
welfare, utility, and to maximize his satisfaction by consuming an optimal
combination of goods within budget constraints, represented by the line ab. At current prices, he could buy
eight bottles of wine or eight loaves of bread; however the consumer will
maximize his utility by consuming an optimal bundle of wine and bread, in this
example four bottles and four loaves.
This graph can also illustrate the increase of consumer
welfare by improvements in the means of production and distribution. Increased
productivity will lower the prices of wine and bread, resulting in more
utility. If you meet an economist, call him a hedonist. A recent Brookings
Institute study
reports that absolute levels of increased GDP per capita are related to
increased levels of happiness.
Whether applied to profit maximizing firms on the supply
side or to utility maximizing individuals on the demand side, economics makes
these key assumptions of rationality. The following discusses the personal
dimensions of value investing and suggests the conditions that are conducive to
rational 1 markets.

Value investors are concerned with the principle of
rationally calculated investment value, purchasing stock at a discount from its
intrinsic value. What does being concerned with principle require? (At this
point, our readers will probably note.) Being concerned with principle, one
author states, requires a certain maturity and a knowledge of one’s
long-term interests. That states perfectly, on the personal level, what value
investing is all about. Think about Warren Buffet. How then does a value
investor cope with turbulent markets? Falling markets unearth investment
opportunities; it’s just that simple.
Our discussion about financial markets however proceeds
further to the current credit crisis as an example. Real markets respond to
events and swing (error-correct) around a valid, econometrically determined and
rational equilibrium point. Thus, MIT economist Charles Kindleberger writes in Manias, Panics, and Crashes (2000 ed.),
“It is much easier to agree that most markets behave rationally most of the
time than that all markets do so all the time.” 2 We have shown that the U.S. stock market,
the result of group behavior, error corrects moderately around a rational
equilibrium when events are predictable. It can, however, respond wildly to
large and unique events whose quantitative import is unclear, either good like
the invention of the Internet or bad like large OPEC price hikes or present
credit and foreign policy problems. People impute meanings to events,
sometimes excessively under uncertainty.
At the level of society, what causes market turbulence?
How to deal with it? Whereas societies are based upon values that are generally
(we’re being very careful about this point) similar, markets are based upon
values, perceptions, wants – an economist would say parameters – that are
different. As an example, lenders rushing for liquidity. Markets can be highly
turbulent when rapid change occurs. Our reasoning at this point necessarily goes
beyond the quantitative into the analogical. Kindleberger writes in the
language of medicine: describing the fever of speculation, contagion, and the
pathology of high leverage. In a recent book, Richard Bookstaber (2007)
uses the language of physics. Describing the panic of 1987, he writes:
The huge volatility of the market broke down all but
the most fundamental relationships between the market securities. The usual
day-to-day world where investors cared about subtleties like corporate
earnings or analyst forecasts dissolved as the energy of the market was
turned up. All stocks moved together; if it was a stock, it was sold. The
market hardly differentiated between domestic and foreign, small cap or
large. It was like plasma physics. As matter becomes hotter it becomes less
differentiated…just a seething white-hot blur of matter. 3
No rationality and stable asset correlation factors
there.
Although each economic downturn has its differences, Kindleberger
elucidates certain stages in the pathology of crashing markets. We paraphrase
and repeat from an earlier article.
Speculation begins when:
1)
There is an exogenous shock to the macroeconomic system such as
the outbreak or
the end of a war, a bumper harvest, a crop failure,
adoption of an invention with
widespread effects... .
2) The monetary means of payment is expanded
by the banking system,
the development of new credit
instruments.
3) Euphoria results in the
overestimation of future profits, or we would
say the underestimation of risk.
4) Excessive gearing (leverage)
arises from cash requirements that
are low relative to the price of
the asset.
5)
As the number of firms and households involved grow large,
speculation for profit leads
away from normal rational behavior
to what has been described as
"manias."
6) The speculation detaches itself
from really valuable objects
and turns toward delusive ones.
7) At some stage, a few insiders
decide to take profits and sell
out. At the market top, there is hesitation as the purchases of
new
speculators are balanced by
insider sales.
8) There ensues a period of
financial distress, as it is perceived
that there is
risk to the overestimated profits and that markets
cannot go higher. For the
economy as a whole, there is the
perception that a rush for liquidity
may develop. The next
stages may or may not happen.
9) Prices decline as the race is on
to be out of real
or long term financial assets
and into cash.
10) Prices fall to the point that
people are again tempted
to move back into less liquid
assets, markets simply
cease, or a lender of last resort such as the Fed succeeds
in convincing the market that
there will be enough money
made available to meet the
increased demand for liquidity. 4
This model allows us to put the current subprime mortgage
crisis in the context of previous crises. For step 5, fill in the originating
subprime lenders’ failure to do the most elementary credit verifications that
might “kill the deal,” as they shoveled money out the door 5. For
step 6, fill in the funding creations of structured finance: the SIVs, CDOs,
CDO2, CDO3, and so on. However, all
crises have their differences. The scope of this credit crisis is different
from those previously because it now extends around the world from a town in
Norway that invested in subprime CDOs to the canyons of Wall Street, involving
the largest economy in the world, accounting for nearly 25% of the world’s
GDP. When people are uncertain of the
values in markets, they simply cease to trade. Forget about return on
investment when return of
investment is the major concern, and so on. Needless to say, seized up
financial markets are not good for the real economy because of restricted
credit flows.
In this environment, what is a value investor to do. The
prescription of value investing is simple. When a stock has a high margin of
safety (that is a current price sufficiently below the calculated equilibrium
price) hold your nose and buy. Due to the many moving parts in this current
financial crisis – deleveraging, globalization, government policy, developing
recession in the real economy – that’s not what we’re going to do, exclusively.
When adding stocks, we’re going to establish initial
stock positions during difficult market moments and then phase in when we think
the general market has bottomed and is beginning to recover. That is how we’re
going to apply the principle of value investing to present economic
realities.
