Expected return: Expected return of the market refers to the return earned from the market over and above the risk-free rate of return . Risk-free rate of return, is the return that an investor must demand for inflation and the time-value of money, even when there is hardly any risk of any financial loss. Risk premium varies with the systematic risk in an investment. It is the market risk premium multiplied by the beta (ß) of a security. It is determined as the market risk premium multiplied by the beta of the security. The market risk premium is equal to the expected market return less the return earned from risk-free security. The expected return can be calculated using the formula given below. Where, is the expected return. is the risk free rate of return. is the beta of the asset. is the expected return of the market.

Summary Introduction

Expected return:

Expected return of the market refers to the return earned from the market over and above the risk-free rate of return. Risk-free rate of return, is the return that an investor must demand for inflation and the time-value of money, even when there is hardly any risk of any financial loss. Risk premium varies with the systematic risk in an investment. It is the market risk premium multiplied by the beta (ß) of a security. It is determined as the market risk premium multiplied by the beta of the security. The market risk premium is equal to the expected market return less the return earned from risk-free security.

The expected return can be calculated using the formula given below.

Where,

is the expected return.

is the beta of the asset.

is the expected return of the market.

Beta:

Beta measures the change in percentage in the excess return of a particular security for 1% change in the excess return of a market portfolio or a benchmark portfolio. The beta of a market portfolio is always 1. However, the securities may have either higher or lower betas as compared to the beta of the market portfolio. The primary reason for this difference is the sensitivity of the individual industries to the economy.

The beta of a portfolio is the weighted average beta of the overall stocks in a portfolio.

The beta of a portfolio with three stocks, Stock E, Stock C, and Stock K can be calculated using the formula given below.

Where,

is the beta of a portfolio.

is the weight of a stock.

(a)

To determine:

The beta needed for the expectation to be consistent with the CAPM.

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.
