Binary Options: When investment becomes gambling
Introduction to derivatives
A derivative is a financial instrument whose value
is derived from an underlying asset or group
of assets. They are a contract between two or
more parties. The value of this contract depends
on changes in the value of the asset that the
derivative’s value is derived from. Derivatives can
also be thought of as bets on a change in price,
or as insurance. Examples of underlying assets
are stocks, bonds, and commodities. These
derivatives are linked to a specific financial
instrument or indicator or commodity, and
through which specific financial risks can be
traded in financial markets in their own right.
Transactions in derivatives should be treated
as separate transactions rather than as integral
parts of the value of underlying transactions
to which they may be linked. Unlike debt
instruments, no principal amount is advanced
to be repaid and no investment income accrues.
Derivatives are used for a number of purposes
such as risk management, hedging, arbitrage
between markets, and speculation.
Derivatives enable parties to trade specific
financial risks - such as interest rate risk,
currency, equity, commodity price risk, and
credit risk - to other entities who are more
willing, or better suited, to take or manage these
risks, typically, but not always, without trading
in a primary asset or commodity. The risk
embodied in a derivative contract can be traded
either by trading the contract itself, such as with
options, or by creating a new contract which
embodies risk characteristics that match, in a
countervailing manner, those of the
existing contract owned.
Derivatives contracts are usually settled by
net payments of cash, often before maturity
for exchange traded contracts such as
commodity futures. Cash settlement is a logical
consequence of the use of derivatives to trade
risk independently of ownership of an underlying
item. However, some derivative contracts,
particularly involving foreign currency, are
associated with transactions in the
underlying item.
The value of the derivative derives from the
price of the underlying item: the reference
price. Because the future reference price is not
known with certainty, the value of the financial
derivative at maturity can only be anticipated
or estimated. The reference price may relate to a
commodity, a financial instrument, an interest
rate, an exchange rate, another derivative, a
spread between two prices, an index or basket of
prices. An observable market price or index for
the underlying item is essential for calculating
the value of any financial derivative. If there
is no observable prevailing market price for
the underlying item, it cannot be regarded as a
financial asset
.
Derivative products initially emerged as hedging
devices against fluctuations in commodity prices,
and commodity-linked derivatives remained
the sole form of such products for almost three
hundred years. Derivatives came into spotlight
in the post-1970 period due to growing instability
in the financial markets. However, since their
emergence, these products have become very
popular and by 1990s, they accounted for about
two-thirds of total transactions in derivative
products. In recent years, the market for financial
derivatives has grown tremendously in terms
of their variety, complexity and turnover. In the
class of equity derivatives, futures and options
on stock indices have gained more popularity
than on individual stocks, especially among
institutional investors, who are major users of
index-linked derivatives. Even small investors
find these useful due to high correlation of the
popular indexes with various portfolios and ease
of use. The lower costs associated with index
derivatives vis–a–vis derivative products based
on individual securities is another reason for
their growing use.
Recently, the dangers and risks embedded in
derivatives have come to the forefront. A major
reason for this is because of counter-party risk.
Most derivatives are based on the person or
institution on the other side of the trade being
able to live up to the deal that was struck. If
society allows people to use borrowed money
to enter into all sorts of complex derivative
arrangements, we could find ourselves in
a scenario where everybody carries these
derivative positions on their books at large
values only to find that, when it’s all unravelled,
there’s very little money to circulate because
a single failure or two along the way wipes
everybody out with it. The problem becomes
exacerbated because many privately written
derivative contracts have built-in collateral calls
that require a counterparty to put up more cash
or collateral at the very time they are likely to
need all the money they can get, accelerating
the risk of bankruptcy
.
The following three broad categories of
participants - hedgers, speculators, and
arbitrageurs trade in the derivatives market.
Hedgers face risk associated with the price of
an asset. They use futures or options markets to
reduce or eliminate this risk. Speculators wish
to bet on future movements in the price of an
asset. Futures and options contracts can give
them an extra leverage; that is, they can increase
both the potential gains and potential losses in a
speculative venture. Arbitrageurs are in business
to take advantage of a discrepancy between
prices in two different markets. If, for example,
they see the futures price of an asset getting
out of line with the cash price, they will take
offsetting positions in the two markets to
lock in a profit.
