Understanding the
difference between square off and exercising an option
Options trading is
a significant part of the financial markets, offering flexibility and
opportunity for both hedging and speculation. Within options trading, two
important concepts that traders frequently encounter are “square off” and
“exercise.” While both actions involve closing an open options position, they
are fundamentally different in nature and purpose. In this article, we will
explore these concepts in detail to understand how they work, when traders use
them, and the risks and rewards associated with each.
1. Overview of
options trading
Options are
financial derivatives that give the holder the right, but not the obligation,
to buy (call option) or sell (put option) an underlying asset at a
predetermined price (strike price) before or on a specified date (expiration
date). The buyer of the option pays a premium for this right, while the seller
(writer) of the option is obligated to fulfill the contract if the buyer
chooses to exercise the option.
Options can be used
in several strategies, including speculation, hedging, and income generation.
There are two types of options:
Call option: This gives the buyer the right to purchase the
underlying asset at a specified strike price.
Put option: This gives the buyer the right to sell the
underlying asset at a specified strike price.
Within the
lifecycle of an options contract, traders can choose to "square off"
or "exercise" their options, depending on their goals and market
conditions. Let’s delve into what each term means.
2. What Does
"Square Off" Mean in Options Trading?
Square off refers
to closing an existing options position before the expiration of the contract.
In simpler terms, it means selling or buying back an option to nullify an open
position. If a trader initially buys an option, squaring off would involve
selling the same option contract in the market. Conversely, if a trader sells
(writes) an option, squaring off involves buying back the option contract.
When you square off
an options position, you are not exercising the contract; instead, you are
settling the position by taking the opposite action. Squaring off is common for
traders who do not intend to hold the option until expiration and are looking
to either lock in profits or cut losses before the contract expires.
3. Benefits and uses
of squaring off
Profit taking: Traders often square off their options to lock
in profits when the market moves in their favor. For instance, if you bought a
call option and the price of the underlying asset increases, you can square off
the call option at a higher premium to book your profits.
Limiting losses: Squaring off is also used as a strategy to
limit potential losses. If the market moves against your position, squaring off
allows you to exit the trade before further losses accumulate.
Avoiding expiry: By squaring off, traders can avoid the
complexities of dealing with the actual exercise or expiry of the options
contract. This is particularly useful for traders who are speculating on
short-term price movements and do not want to hold an option until maturity.
Cash settlement: In some markets, especially where options are
cash-settled, squaring off is a common practice as it enables traders to exit
without involving physical delivery of the underlying asset.
4. What Does
"Exercise an Option" Mean?
Exercising an
option refers to the process of enforcing the rights granted by the options
contract. When a trader exercises an option, they are choosing to either buy
(in the case of a call option) or sell (in the case of a put option) the
underlying asset at the strike price. This is only relevant if the option is
"in the money," meaning the strike price is favorable compared to the
current market price of the underlying asset.
For example:
Call option: If you hold a call option with a strike price
of Rs.50 and the underlying asset is trading at Rs.60, you would exercise your
option to buy the asset at Rs.50, which is below the market price.
Put option: If you hold a put option with a strike price of
Rs.70 and the underlying asset is trading at Rs.60, you would exercise your
option to sell the asset at Rs.70, which is above the market price.
Exercising an
option leads to a direct transaction involving the underlying asset. For
American-style options, the option holder can exercise at any time before
expiration. For European-style options, exercise is only possible at
expiration.
5. Benefits and uses
of exercising an option
Ownership transfer:
Exercising a call option results in the
ownership of the underlying asset, which could be beneficial if the asset’s
price is expected to rise further. Conversely, exercising a put option allows
the trader to sell the asset at a higher strike price than the market value,
locking in profits.
Realizing profits
from intrinsic value: Exercising an
option allows traders to capitalize on the intrinsic value of the option, which
is the difference between the strike price and the underlying asset's market
price. If the option is significantly in the money, exercising could yield
considerable profits.
Hedging purposes:
Investors might exercise options as part
of a broader hedging strategy to protect their portfolios. For instance,
exercising put options can be a defensive move to protect against downside risk
in a falling market.
6. Key differences
between squaring off and exercising an option
Feature Square Off Exercise
Nature Closing the
position by taking the opposite trade Enforcing
the right to buy/sell the underlying asset
Market Role Speculative,
used by traders who do not want delivery of the asset More strategic, used by investors wanting to own or sell
the asset
Time of Action Can be
done anytime during the life of the option For
American options, can be exercised anytime; for European, only at expiry
Involvement of Underlying Asset No direct involvement with the underlying asset Direct involvement, leading to purchase or sale
of the asset
Profit Realization Through
the premium difference between buying and selling Through the intrinsic value at the time of exercise
Execution Complexity Simple,
just a reversal of the existing position More
complex, involves transferring ownership of assets
7. Scenarios when
traders square off vs. exercise
Squaring off: A trader buys a call option on a stock with a
strike price of Rs.100, and the premium paid is Rs.5. Later, the stock price
increases to Rs.110, pushing the premium of the option to Rs.10. Instead of
exercising the option, the trader squares off by selling the option at the
current premium, making a profit of Rs.5 (Rs.10 – Rs.5).
Exercising the option:
An investor buys a call option with a
strike price of Rs.50, and the underlying asset rises to Rs.70. The investor
exercises the option, buying the asset at Rs.50 and gaining immediate ownership
of an asset worth Rs.70, securing a Rs.20 profit per share (minus the premium
paid).
8. Which is Better:
Squaring Off or Exercising?
The decision to
square off or exercise depends on the trader’s objectives and market
conditions. Traders looking for short-term profits typically prefer to square
off, while investors who want to take ownership or sell the underlying asset
might choose to exercise the option.
For speculators: Squaring off is generally more efficient,
especially for traders who are primarily interested in short-term price
movements.
For long-term investors:
Exercising is beneficial when they want
to own the underlying asset, particularly when it’s trading significantly in
the money.
Conclusion
Both squaring off
and exercising an option are essential strategies in options trading, each
serving different purposes. Squaring off is commonly used by traders to lock in
profits or cut losses without involving the underlying asset, whereas
exercising is for those looking to either acquire or sell the asset itself.
Understanding the right time to employ each strategy is key to maximizing
returns and minimizing risks in the dynamic world of options trading.
