Consider a European call and a European put with the same strike price and time to maturity. Show that they change in value by the same amount when the volatility increases from a level ₁ to a new level 2 within a short period of time. (Hint: Use put-call parity.)
i)identify, analyze and discuss the following characteristics of an American put option: maximum value, intrinsic value, time value, lower bound, and payoff at expiration. ii) analyze and discuss the following factors on an American put option: time to expiration, exercise price, interest rate, volatility, and dividends. iii) identify, analyze, and discuss the following characteristics of a European call option: maximum value, intrinsic value, time value, lower bound, and payoff at expiration. iv) analyze and discuss the following factors on a European call option: time to expiration, exercise price, interest rate,
Wich of the following Statement about the bionominal Option pricing model by Cox and Ross ist false I)the model uses a recombining tree ii)the martingale probability is constant III)The martingale probability equal 0.5 to Provider a fair Game iv) the model uses a multiplicative process rather thatba additive process
Which of the following is correct? O A. Common stock valuation usually treats the common stock as a perpetuity. OB. The appropriate measure for risk according to the capital asset pricing model is beta. OC. The present value of a $100 perpetuity discounted at 5% is $2,000. OD. The incremental cost is the cost of making a choice defined in terms of the next best alternative that is foregone. OE. Both B and C.
Which of the following statements about European option contracts is TRUE? a. Typically American options are cheaper than otherwise similar European options due to the uncertainty regarding the date of exercise. b. One can synthesise a long forward position in the underlying by being long a call and short a put c. A long call position and a short put position both involve buying the underlying and so are equivalent d. The price of an option can be obtained by computing the true probabilities of each state of nature, working out the expected option payoff across those states and then discounting back to the present.
Consider the following two scenarios whereby the cost-of-carry model is violated. You are required to select appropriate missing words and fill in question 1. a. long b. spot c. over priced d. short arbitrage e. under priced f. long arbitrage g. futures h. short Question 1 a. If ft >S0 (1 + rf - d)^t, then the( ) is ( )relative to ( ) or equivalently, the quoted futures price is higher than what it should be. Thus, the correct arbitrage strategy should be: ( ) the futures contract and ( )the spot market. This strategy is also known as ( ). b. If ft <S0 (1 + rf - d)^t, then the( ) is ( )relative to ( ) or equivalently, the quoted futures price is lower than what it should be. Thus, the correct arbitrage strategy should be: ( ) the futures contract and ( )the spot market. This strategy is also known as ( ).
We believe that the single factor model can predict any individual asset’s realized rate of return well. Both Portfolio A and Portfolio B are well-diversified: ri = E(ri) + βiF + Ei, where E(ei) = 0 and Cov(F, i) = 0 A B β 1.2 0.8 E(r) 0.1 0.08 (1) What is the rate of return of the risk-free asset? (2) What is the expected rate of return of the well-diversified portfolio C with βC = 1.6, which also exists in the market? (3) A fund constructs a well-diversified portfolio D. Studies show that βD = 0.6. The expected rate of return of D is 0.06. Is there an arbitrage opportunity? If so, construct a trading strategy to earn profits with no risk. If not, why?
Figure 2 (a) Financial engineering deals with the design of new assets. Draw the payoff (at t=1) of the following butterfly spread: payoff of portfolio Purchase 1 call with exercise price a Sell 2 calls with exercise price (atb)/2 Purchase 1 call with exercise price b as a function of the underlying stock price S at t=1 where a=120 and b=140. (b) An individual agent thinks that there is a high probability that the Dow Jones will have a payoff (or points) between a=34,000 and b-36,000 at t=1. 1=nd Design a digital option (see Figure 1) as a sequence of calls on the Dow that converges to a pure bet on getting $1 on the interval [34,000, 36,000]. ie, if the Dow lies between SE[34,000, 36,000] at t=1, then the portfolio of calls pays off exactly $1. The payoff is 0 otherwise. a+8 Figure 1 (Digital option) payoff a=34,000 b-36,000 S. Hint: You have to modify the sell strategies of a butterfly spread to obtain a payoff as given in Figure 2 and then adjust n and 8 appropriately.
4d) Price the European call having strike 60 GBP. Use the two-periods binomial model with u = 1.1, d = 0.9 and ∆t = 1. Assume that the risk free rate is 5%, and the current price of the underlying asset is 50 GBP.
The premium on a call option is primarily a function of the difference in spot price S relative to the strike price X, the length of time until expiration T, and the volatility of the currency o. C = f(S-X, T, o) For each characteristic of a call option, use the table to indicate whether that would lead to a higher call option premium or a low call option premium (all else equal). Characteristic A lower spot price relative to the strike price A shorter time before expiration A higher level of volatility for the currency Higher Call Option Premium O Lower Call Option Premium When using a call option to hedge payables in an international currency, a U.S. based MNC can lock in the to obtain the needed foreign currency. maximum minimum amount of dollars needed
What is the expected return on asset A if the expected return on the market is 8%, the risk-free rate is 4%, and the Beta of asset A is 2? You want to use Capital Asset Pricing Model (CAPM) Group of answer choices A) 12% B) 20% C) 16%
For each of the following option positions state the risk profile, draw the profit and loss area and show the breakeven price on each graph. a) Long 7.00 call @ 0.30 b) Short 7.00 call @ 0.30 Risk profile: Risk profile: c) Long 7.00 put @ 0.20 d) Short 7.00 put @ 0.20 Risk profile: Risk profile:
