Call option:
A call option is an agreement where the buyer is entitled to a right to buy a stock at a pre-specified price (known as exercise price or strike price) within a pre-specified period. The stock on which the call option is provided is called the underlying asset.
Put option:
It is an agreement where the buyer is entitled to a right to sell a stock at a pre-specified price (known as exercise price or strike price) within a pre-specified period. The stock on which the put option is provided is called the underlying asset.
Hedge ratio:
A hedge ratio indicates the level of exposure of an investment to risk. For example, if a hedge ratio for an investment is 0.60 or 60%, it means 60% of that investment is protected from risk and remaining 40% of the investment is exposed to risk. A hedge ratio is calculated by dividing the option price range by the stock price range.
To compute:
The hedge ratio when the exercise price is
- $120
Determine the impact of more in the money on hedge ratio.
Answer to Problem 7PS
The hedge ratio is
When the option becomes progressively more in the money, the value of the hedge ratio increases. It indicates that it is possible to protect the investment more, when the option becomes progressively more in the money.

- Which of the following is true: The BSM model combined with the put call parity can be used to give the theoretical price of an American put option. One of the variables that influences the price of the option is the expected return on the stock. Since dividends could trigger an early exercise of an American call, the BSM formula dividend adjustment will provide the correct price of an American call. The BSM formula requires cumulative probabilities from the lognormal distribution. The BSM model may be used with currency options by replacing the dividend yield with the foreign interest rate.arrow_forwardAn option is trading at $3.45.
