The very word ‘risk’ evokes
different meanings for different people. It is perhaps to prove this point that
risk has many variants of its definition: Possibility of loss or injury; peril;
a dangerous element or factor; a chance of loss or the perils and the degree of
probability of such loss; a chance of injury, damage or loss; the possibility
of suffering harm or loss; danger; hazards; a factor, element or course
involving uncertain danger; the danger or probability of loss.
Risk
has Many Overtones
The basic concept of risk is very
simple: In financial terms, it is the potential change in the price of an asset
or commodity. Risk denotes both the upside and downside of the price movement.
But, we rarely consider the upside movement as risk. In routine life we always
use risk to denote the most “undesirable” and that is the “loss”. And this
commonsense dictum gets vindicated when we say that people are naturally risk averters,
which only means that people are in for gains but not for losses. This simply
means that risk is always used in a negative connotation.
Risk always rests in the future. It
is there in everything we do. It is all pervasive and has a profound impact on
mankind. Certain risks are known to have only downside but no chance of gain.
On the other hand, certain risks are diversifiable while certain others are
not. But none of them are said to be extinguishable; at best they can be
transferred. Risk retains its fullness, no matter who transfers to whom, who
buys from whom or how much of it is bought or sold, until at least it
extinguishes on its own.
Risk is dynamic. It is an abstract
parameter requiring a degree of intellect to measure it. Yet, it cannot be
measured directly. It can only be calibrated for it is not a naturally
occurring phenomenon. It requires the integration of at least two quantities
viz—the chance and the type of event. It is also said that risk cannot be
forecasted precisely for it is dynamic. To better appreciate its dynamic
nature, let us represent the probability and consequence of risk, which is a
direct function of these two factors, as coordinate axes in a common x-y plot
configuration. In mathematical terms, these variablesprobability (P) and
consequence (C) and the subsequent risk value can be represented by a point in
a two-dimensional Euclidean coordinate system. Every ordered pair of
probability value and its corresponding consequence value, (P,C) represents one
and only one point in this system (Figure 1).
Risk being a relative measure, it
matters less where an investor or an organization starts in the risk coordinate
system than how its risk changes over time and in what specific direction the
risk values move within the coordinate system (Figure 2).
In view of its dynamic nature, risk
would acquire a different dimension on a long-term scale.
Risk is also not straightforward for
there is another dimension to it: The risk of ‘opportunity losses’. This very
complexity and dynamism of all pervasive risk has perhaps made life more interesting
to live by eternally challenging one’s ability to fight it out, endurance to
withstand it and ingenuity to circumvent it.
Hedging:
Origins
Risk analysis is said to be natural
and an innate characteristic of human nature. True, everyday, we use
information to reduce our risks of perceived hazards by altering our style of
living such as regulating our eating habits, avoiding smoking, using smoke alarms
and so on for the purpose of reducing our risk of injury, disease or death. It
is amazing how people take the best possible decisions to deal with this kind
of inescapable trade-offs in life. They are perhaps well ingrained with the
concept of giving off something in return for more of something that they most
cherish to own. The pursuit of hedging is thus perhaps as old as civilization though
it has become a buzzword in the recent past.
One reason for the current hedging-mania
could be our improved mental faculties and consequently the “know” of more. The
more we know, the more evident risk is becoming. Indeed ‘risk’ has become a
shuddering word for any one to pronounce in today’s world. It has been our eternal
struggle: Men were longing to create an element of ‘certainty’ amidst
‘uncertainty’. One such classic example of man’s craving for certainty is the Bretton
Woods system of fixed exchange rates. However, it did not lost long. By 1970 it
became increasingly difficult to afford certainty to exchange rates and with
the result, Bretton Woods system collapsed paving the way for the ‘uncertainty’
to once again rule the roost.
This collapse and its aftermath
have only intensified men’s search for ‘certainty’ in the currency markets.
This resulted in the emergence of derivatives followed by other innovations and
stock features as tools to fight out ‘uncertainty’. During the last three
decades they have grown as effective risk management tools. It is said that by
using derivatives, companies or institutional investors can manage effectively
their portfolios of assets and liabilities. But ironically, during the course of
usage, the very derivatives that have taken birth as saviors of investors have
turned out to be very risky and highly leveraged instruments. This reminds us of
the proneness of men to certain systematic flaws of which the most prominent
being the simple overconfidence about our ability to infer, estimate, and predict
the character of unknown events.
Hedging
or Speculating?
In financial terms, hedging is said
to basically aim at reducing the variability of the corporate income/portfolio
income. Another reason why companies or investors go for hedging their exposure
to financial price risk is to improve or maintain their competitiveness in the
market/portfolio value intact.
To better appreciate this mechanism
let us take a deeper look at trading on individual stock derivatives: Assume
that the current portfolio of Ram consists ACC stock whose price he expects to
fall sharply in the near future. To hedge from this fall in price and the
consequent loss, assume Ram sold individual stock futures contract of NSE on
ACC at Rs. 162, expiry date being March 26, 2003 under the assumption that any
fall in the price and the consequent erosion in the value of ACC stock that he
is currently holding will be off-set by the gain he will make under the futures
contract on ACC that he sold. Now, Ram having achieved the objective of keeping
his portfolio intact by going short on individual stock derivatives, labels his
purchase of futures contract as an act of hedging.
But Ram’s example posits quite a
few disturbing questions, such as: When Ram anticipates a fall in ACC price,
why he has not opted for the outright sale of ACC stock ? Or is he not quite
sure of his view? Is selling of futures contract
then, a speculative move? Another most important question here is, what
prompted Ram’s buyer of the futures contract, to buy it? Is he speculating that
the price of ACC will rise? If so, what is he trying to hedge—his future
acquisition of ACC stock? Remember, all these questions merit examination in the
context of what we have seen earlier: No business wants to suffer losses and so
only goes for hedging.
Yet another question: Why Ram has
not gone for a put option on ACC? Why only futures contract? Is it because he
has to shell down premium upfront, if he had gone for option contract on ACC?
In fact, if one watches the volume statistics pertaining to derivatives trading
on Indian bourses one gets wonder struck as to why there is a big difference in
the trading volumes under futures on index and individual stocks and within individual
stocks between futures and options?
All this begets the next logical question:
Is it a speculative move? There is always a thin demarcation between speculation
and hedging. In fact speculation is often disguised as a trading for hedging
for after all speculation is nothing but a bet on the future direction of price
movements. Of course, it combines high risks with high potential rewards and
thus the urge for speculation. And what speculation also needs is conviction of
one’s view of the price movement and lots of guts to spare and lose money, no matter
borrowed or own.
We are back to where we started
off—who is hedging whom? And it is certainly pretty fuzzy! Or, is it that risk
being in the mind of the perceiver as “beauty is altogether in the eye of the
beholder” driving people crazy in different directions. One thing is however
certain: Risk is increasingly becoming bad.
