Examples of Exercise Price

Let’s see some simple to advanced examples of the exercise price to understand it better.

Example #1

If, for example, an investor purchased a call option of 1000 shares of an XYZ company at a strike price of $ 20, then say he has the right to purchase 1000 shares at the price of $ 20 till the date of expiration of the call option period no matter what the market price is. Now, if the market price of the shares rises to $ 40, then the holder of the option to purchase the shares at the rate of $ 20 and can book a profit of $ 20,000 as it allows him to sell the shares at the rate of $ 40 per share getting $ 40,000 after buying it at the rate of $ 20 per share spending $ 20,000.

Example #2

In the derivative marketDerivative MarketThe derivatives market is that financial market which facilitates hedgers, margin traders, arbitrageurs and speculators in trading the futures and options that track the performance of their underlying assets.read more, the exercise price determines whether the money can be made by the investor or not.

Let’s take the different scenarios of Intel Corporation, where the underlying stock is trading at $50 per share, and the investor has purchased a call option contract of Intel Corporation at a premium of $5 per contract. The lot of each option contract is 50 shares; therefore, the actual cost of the call option is $250 (50 shares* $5).

Now the situation of the investor in different scenarios:

  •  At the expiration of the Contract, Intel Corporation Stock is Trading at $60.

In this scenario, the investor has the right to purchase the call option at $50, and then he can immediately sell the same at $60. Here the exercise price is below the market price; the option is said to be in the money. Now the investor will purchase the shares at $50 per share, spending a total of $2500 ($50*50), and then sell them at $60 per share getting $3500 ($60*50), making a profit of $1000. Hence, the net profit for the above transaction is $750, as a premium of $250 premium was paid while purchasing the option contractOption ContractAn option contract provides the option holder the right to buy or sell the underlying asset on a specific date at a prespecified price. In contrast, the seller or writer of the option has no choice but obligated to deliver or buy the underlying asset if the option is exercised.read more.

  • At the expiration of the contract, the Stock is Trading at $52.

Using a similar analysis done above, the worth of the call option will be $2 per share or $100 in totality. Here, the exercise price is very near to the stock market price. As the investor has paid a premium of $250 so he has to book a loss of $150 ($250 – $100).

  • At the expiration of the contract, the Stock is Trading at $50.

Here the market price of the stock is at par with the strike price. So the investor has a loss equal to the option premium paid by him, i.e., $250.If the price of the stock is at or out of the money, then the loss is always limited to the option premium paid.

Important Points

  1. While trading in options, the buyer of the option contract needs to pay the cost of buying the option, which is known as premium. If the buyer uses the right, then they are said to be exercising the option.
  2. It is beneficial to exercise the option if the strike price is below the underlying security market price in case of the call option or if the strike price is above the market price, then one should exercise the option in case of a put option.
  3. When the person is trading in options, he can choose out of the different strike price ranges that are predetermined by the exchange. With time the entire range of strike prices may expand beyond initially listed boundaries because of the large market movements.

Conclusion

Thus the exercise price or strike price is the key variable between two parties in a derivative contract. It is the price where the person dealing in option has control of the underlying stock in case if he chooses to exercise the option. In the call option, the strike price is the price that the buyer of an option must pay to the writer of the option, and the input option strike price is the price that the writer of an option must pay to the holder of the option. The same does not change and remains the same even if the price of the underlying security changes, i.e., regardless of the price at which underlying security is, the exercise price is remains fixed when one buys an option contract.
