Market Portfolio: A market portfolio refers to a kind of portfolio that comprises of several risky investments, with each individual investment in portfolio weighted in proportion to its value. Such portfolios consist of all outstanding shares of all the risky securities. A market portfolio can also be referred to as a theoretical bundle of investments comprising of all the assets available in the financial market. The expected return of a market portfolio is same as the expected return of a market as a whole. The market portfolios for the stocks are value-weighted portfolios as each individual security is held in proportion to its market capitalization. To determine: The trade necessary to keep the portfolio value weighted.

Use the binomial method to determine the value of an American Put option at time t = 0. The option expires at time t = T = 1/2 and has exercise price E = 55. The current value of the underlying is S(0) = 50 with the underlying paying continuous dividends at the rate D = 0.05. The interest rate is r = 0.3. Use a time step of St = 1/6. Consider the case of p = 1/2 and suppose the volatility is σ = 0.3. Perform all calculations using a minimum of 4 decimal places of accuracy. =

Consider a European chooser option with exercise price E₁ and expiry date T₁ where the relevant put and call options, which depend on the value of the same underlying asset S, have the same exercise price E2 and expiry date T₂. Determine, in terms of other elementary options, the value of the chooser option for the special case when T₁ = T2. Clearly define all notation that you use.

The continuous conditional probability density function pc(S, t; S', t') for a risk neutral lognormal random walk is given by Pc(S, t; S', t') = 1 σS'√2π(t' - t) - (log(S/S) (ro²)(t − t)] exp 202 (t't) In the binomial method, the value of the underlying is Sm at time step môt and the value of the underlying at time step (m + 1)St is Sm+1. For this case evaluate Ec[(Sm+1)k|Sm] = [°° (S')*pc(S™, mdt; S', (m + 1)8t)dS' showing all steps, where k is a positive integer with k ≥ 1. You may assume that 1 e (x-n)2 2s2dx = 1 for all real numbers n and s with s > 0.
