3. (5 points) A stock selling at $100 will either go up at the rate of u = 10% or go down at the rate of d = -10% each month for the next two months. The constant risk-free rate is 1% per month. Use a two-period binomial model and the Risk-Neutral Valuation Relation to compute a European call and put on the stock with strike (exercise) price X = $95 and maturing in two months.

Step 1
The up stock price after one month = $100 * (1 + 10%) = $110 The down stock price after one month = $100 * (1 - 10%) = $90 The up stock price after two months = $110 * (1 + 10%) = $121 The down stock price after two months = $90 * (1 - 10%) = $81 Show more…

Consider pricing European options on a stock with an initial price of $142 and a strike price of $142. The options mature in 9 months, and the risk-free rate of interest is 4.50% per annum. The volatility is σ = 0.16. If a 70 period binomial tree is to be used, then the up move, u, in the stock price using the Jarrow-Rudd (JR) solution is: 1.01705 0.98357 0.98391 1.01670

A stock price is currently S = 100. Over the next year, it is expected to go up by 100% (u = 2) or down by 50% (d = 0.50). The risk-free interest rate is r = 20% per annum with continuous compounding. What is the value of a 12-month European Put option with a strike price K = 100? Select one: a. €22.50 b. €26.25 c. €21.25 d. €25.00 e. €23.75

A stock price is currently $$\$ 40 .$$ It is known that at the end of 3 months it will be either $$\$ 45$$ or $$\$ 35 $$ The risk-free rate of interest with quarterly compounding is $8 \%$ per annum. Calculate the value of a 3 -month European put option on the stock with an exercise price of $$\$ 40 .$$ Verify that no-arbitrage arguments and risk-neutral valuation arguments give the same answers.
