What is the underlying assumption of the Black-Scholes-Merton model regarding the distribution of stock prices?
Lognormal distribution
What is the risk-neutral valuation approach used for in the Black-Scholes-Merton model?
To determine the expected return on an option
What is the cumulative normal distribution function used for in the Black-Scholes-Merton model?
To calculate the probability of the option expiring in the money
How does the volatility of the underlying asset affect the Black-Scholes-Merton option price?
It increases the option price
What is the purpose of the Black-Scholes-Merton differential equation?
To describe how the value of an option changes over time
How do dividends affect the Black-Scholes-Merton option price?
They decrease the option price
What is the key assumption underlying the pricing of forward contracts for investment assets, and how does it relate to the capital asset pricing model?
The key assumption is that the risk-free rate is equal to the expected return on the asset, implying that the asset's expected return is equal to the risk-free rate. This assumption is related to the capital asset pricing model, which states that the expected return on an asset is a function of its beta and the market risk premium.
How do futures prices on stock indices differ from forward prices, and what are the implications for investors?
Futures prices on stock indices are marked-to-market, whereas forward prices are not. This means that futures prices are adjusted daily to reflect changes in the underlying index, whereas forward prices are fixed at the time of contract inception. This has implications for investors, as they must post margin to cover potential losses on futures contracts.
What is the cost of carry, and how does it affect the pricing of forward and futures contracts on commodities?
The cost of carry refers to the storage, insurance, and other costs associated with holding a physical commodity. It affects the pricing of forward and futures contracts by increasing the forward price, as the buyer must compensate the seller for these costs.
Under what conditions are forward prices and futures prices equal, and what are the implications for investors?
Forward prices and futures prices are equal when the risk-free rate is equal to the expected return on the asset, and there are no arbitrage opportunities. This implies that investors can earn the same return from either a forward or a futures contract, and can switch between the two without incurring additional costs.
How do delivery options affect the pricing of forward and futures contracts, and what are the implications for investors?
Delivery options allow the buyer to choose the delivery date, location, or quality of the underlying asset. This can affect the pricing of forward and futures contracts by increasing the flexibility of the contract, and hence the value to the buyer.
What is the relationship between futures prices and expected future spot prices, and how does it relate to the efficient market hypothesis?
Futures prices reflect the market's expected future spot price, adjusted for the cost of carry and other factors. The efficient market hypothesis suggests that futures prices are unbiased estimates of the expected future spot price, and that any deviations from this estimate are quickly arbitraged away.
How does the concept of real options extend the traditional capital investment appraisal framework, and what are the implications for valuing a business?
Real options extend the traditional capital investment appraisal framework by considering the flexibility and uncertainty associated with investment decisions, allowing for the valuation of options to expand, contract, or abandon a project. This approach recognizes that investment opportunities have inherent value beyond the initial outlay, and can be used to estimate the market price of risk.
What are the key lessons that can be learned from derivatives mishaps, and how can they be applied to users of derivatives?
The key lessons from derivatives mishaps include the importance of understanding risk exposure, avoiding over-reliance on complex models, and maintaining adequate risk management practices. These lessons can be applied to all users of derivatives, including financial institutions and non-financial corporations, by promoting a culture of risk awareness and rigorous risk management.
How does the capital asset pricing model (CAPM) relate to the concept of market price of risk, and what are the implications for investment decisions?
The CAPM is a framework for estimating the market price of risk, which represents the expected return on an investment in excess of the risk-free rate. This price of risk is a key input in the valuation of investment opportunities, and can inform decisions about the allocation of capital and the management of risk.
What are the key differences between the risk-neutral valuation framework and the traditional capital investment appraisal framework, and how do they approach the valuation of investment opportunities?
The risk-neutral valuation framework approaches the valuation of investment opportunities by assuming that investors are risk-neutral, and that the expected return on an investment is equal to the risk-free rate. In contrast, the traditional capital investment appraisal framework approaches valuation by considering the expected cash flows and the cost of capital. The risk-neutral framework is more flexible and can handle more complex investment opportunities.
How can the concept of real options be used to evaluate options in an investment opportunity, and what are the key benefits of this approach?
The concept of real options can be used to evaluate options in an investment opportunity by recognizing the flexibility and uncertainty associated with investment decisions, and estimating the value of these options using techniques such as binomial models or simulation. The key benefits of this approach include the ability to capture the value of flexibility and uncertainty, and to make more informed investment decisions.
What are the implications of the capital asset pricing model (CAPM) for the valuation of a business, and how can it be used to estimate the cost of capital?
The CAPM implies that the expected return on an investment is a function of the risk-free rate, the market return, and the beta of the investment. This model can be used to estimate the cost of capital for a business, and to inform decisions about the allocation of capital and the management of risk.
