Q

Q

What is a butterfly spread portfolio?

A

Long on 2 Call options with differing strike prices, and short two Call options with K = average strike prices of the first 2 Call options.

52
Q

What is a protective put?

A

Long position on the stock plus a long position on a put over the same stock

53
Q

What happens when we combine a long position in the stock and in a put held on the stock?

A

We eliminate the risk that the stock price decreases and we preserve the possibility to make money if the stock price increases.

54
Q

What do we mean by relative valuation of an option?

A

We price a financial asset as a function of other assets. We use the Put-Call Parity.

55
Q

What do we mean by absolute valuation methods?

A

We price a financial asset by itself. We use the Binomial Model and the Black-Scholes Model.

56
Q

Why does computing the value of an option through the present value of all future cash flows doesn’t work?

A

Because the expected return and risk of an option change (nonlinearly) every time the underlying asset price moves.

57
Q

What are the conditions to use Put-Call Parity?

A

1) Both options (Call and Put) need to be European style.
2) Both options (Call and Put) need to have the same underlying asset.
3) Both options (Call and Put) need to have the same strike price (K).
4) Both options (Call and Put) need to have the same expiration date.

58
Q

True or false: we can use the Put-Call Parity to calculate the price of american options.

A

False

59
Q

True or false: we can use the Put-Call Parity to calculate the price of european options.

A

True

60
Q

True or false: when we use the Put-Call Parity, the options can have different underlying assets.

A

False

61
Q

True or false: when we use the Put-Call Parity, the options can have different strike prices.

A

False

62
Q

True or false: when we use the Put-Call Parity, the options can have different expiration dates.

A

False

63
Q

True or false: when we use the Put-Call Parity, the options need to have the same expiration date.

A

True

64
Q

True or false: when we use the Put-Call Parity, the options need to have the same strike price.

A

True

65
Q

True or false: when we use the Put-Call Parity, the options need to have the same underlying asset.

A

True

66
Q

In the Put-Call Parity, what does it mean if a value is positive?

A

We are selling the respective component.

67
Q

In the Put-Call Parity, what does it mean if a value is negative?

A

We are buying the respective component.

68
Q

What is equivalent to selling a call today?

A

Selling a put today, shorting the underlying asset and depositing the PV(K).

69
Q

What is equivalent to buying a call today?

A

Buying a put today, buying the underlying asset and borrowing the PV(K)

70
Q

What is the same as borrowing the PV(K)?

A

Shorting the PV(K) in a risk-free zero-coupon bonds.

71
Q

What is the same as depositing the PV(K)?

A

Buying the PV(K) in risk-free zero-coupon bonds

72
Q

True or false: dividends always matter when using the Put-Call Parity.

A

False

73
Q

When do dividends matter in the Put-Call Parity?

A

When they’re paid before the expiration date.

74
Q

True or false: we have to consider the same time for PV(K) and PV(DPS).

A

False

75
Q

What maturity should you consider for the PV(K)?

A

Same as options (expiration date)

76
Q

What is the assumption of the Binomial Model?

A

The binomial model has the assumption the underlying asset price evolves throughout time according to a binomial distribution (at each point in time you only have two options: up or down).

77
Q

Which techniques can we use to solve the Binomial Model?

A

Replicating Portfolio and the Risk-neutral probabilities.

78
Q

How do we use the technique of replicating portfolio?

A

We set up an option equivalent by combining the stock (underlying asset) and a risk-free bond with the same payoffs and therefore same value (Law of One Price).

79
Q

How do we use the technique of risk-neutral probabilities?

A

We create risk-adjusted probabilities and apply present value formula with these artificial probabilities.

80
Q

What is the difference between the Binomial Model and the Black-Scholes model?

A

While the Binomial Model assumes discrete changes in stock prices, the Black-Scholes assumes stock prices change continuously. The Black-Scholes Model is a continuous-time version of the Binomial Model: instead of assuming that the underlying asset follows a binomial distribution it assumes that it follows a standard normal distribution.

81
Q

True or false: we can use the Black-Scholes Model to price european options.

A

True

82
Q

True or false: we can use the Black-Scholes Model to price american options.

A

False

83
Q

True or false: we can use the Binomial Model to price american options.

A

True

84
Q

True or false: the Black-Scholes Model can be derived from the Binomial Model.

A

True

85
Q

How can we derive the Black-Scholes Model from the Binomial Model?

A

The Black-Scholes Model can be derived from the Binomial Option Pricing Model by allowing the length of each period to shrink to zero and letting the number of periods grow infinitely large.

86
Q

Which inputs do we need to use the Black-Scholes Model?

A

Current Stock Price, Strike Price, Exercise date, Risk-free rate and the Volatility of the stock.

87
Q

How is the exercise date measured?

A

In volatility’s frequency.

88
Q

True or false: the T in d1 and d2 are the same.

A

False

89
Q

Why is the T different in d1 and d2?

A

Because the periods are always counted in the same frequency as the discount rate.

108
Q

What happens to the call option’s price when the maturity increases?

A

109
Q

A

True

A

False

114
Q

Of the five inputs needed in the Black-Scholes formula, which isn’t observed directly?

A

Volatility

115
Q

What is implied volatility?

A

The volatility of an asset’s returns that is consistent with the quoted price of an option on the asset.

116
Q

How can we estimate the volatility?

A

Use historical data.

117
Q

True or false: The short position in a Call option might have the obligation to buy the underlying asset (e.g., stock) at the strike price.

A

False

118
Q

True or false: The intrinsic value of a Put option is given by the market price of the underlying asset (e.g., stock) minus the strike price

A

False

119
Q

True or false: Consider that the current market price of the underlying asset (e.g., stock) is greater than the strike price of a given Put. That Put option is currently traded out-of-the-money.

A

True

120
Q

True or false: The CAPM model assumes that markets should provide a premium for holding stocks that present higher levels of idiosyncratic risk.

A

False. The CAPM model states that only systematic risk determines the equilibrium return for any security or portfolio. The level of systematic risk is captured through the beta.

121
Q

True or false: According to the CAPM model, two portfolios with the same beta have the same total risk.

A

False. According to the CAPM model two portfolios with the same beta have the same exposure to systematic risk. This does not imply that the idiosyncratic risk presented in each of the two portfolios is the same, and hence it does not imply that the total risk is the same.

122
Q

True or false: . The short position in a Call option might have the obligation to sell the underlying asset (e.g., stock) at the strike price.

A

True

123
Q

True or false: The intrinsic value of a Put option is given by the strike price minus the market price of the underlying asset (e.g., stock).

A

True

124
Q

True or false: The price of an American Call is always higher or equal than the value of an identical European Call (the remaining conditions are the same).

A

True

125
Q

What is a bullish vertical spread?

A

A bull vertical spread is an options strategy used when the investor expects a moderate rise in the price of the underlying asset. Bull vertical spreads involve simultaneously buying and selling options with the same expiration date on the same asset but at different strike prices.

126
Q

When does an investor create a bull vertical spread?

A

When the investor expects a moderate rise in the price of the underlying asset.

127
Q

What is a bearish vertical spread?

A

A bearish vertical call spread is created when the investor sells a call option and buys a higher strike call option with the same expiration date. Bearish vertical call spreads are entered for a credit and are also called call credit spreads. The strategy profits from a decrease in the underlying asset’s price.
