1. Assume that CAPM holds. Suppose that the expected return of the market portfolio is 9% and the standard deviation of market return is 13%. Assume that the covariance of Walmart's stock return with the market is 0.00785 and the standard deviations of Walmart return is 8%. What proportion of Walmart's risk (variance) can be diversified away? 2. Suppose that a firm is considering investing $1M in a project with an expected return of 10%. The standard deviation of the project's return is 25%. The standard deviation of the market portfolio return is 20%. The correlation between the project's return with the market return is 0.4. The expected return of the market portfolio is 9% and the risk free rate is 4%. According to CAPM, should the firm invest in the project (is its expected return higher than the required rate of return according to CAPM)? 3. The current gold price is $2645 per ounce and the current yield of 6-month T-bill is 4.47%. Assume that the cost of storing gold is zero and owning gold does not provide additional income. What must be the futures price of gold in futures contracts maturing in 6 months? If you take a long position to agree to buy 100 ounces of gold at the futures price, what would be your profit/loss if gold price is $2450 per ounce. 4. Firm XYZ's stock is currently trading at $135. The put option on XYZ's stock with a strike price of $120 and an expiration date one year from today costs $8. The call option on XYZ's stock with a strike price of $145 and an expiration date one year from today costs $10. A. If you spent $9000 to purchase 900 of the call options mentioned above. What is your rate of return if XYZ's stock price rises to $150 one year later? B. If you purchased a share of stock and purchased a put option mentioned above. Calculate the payoff, profit, and rate of return of this investment when XYZ's share price is $100 and $150, respectively one year later. 5. Suppose that Apple stock is currently trading at $235 per share. A call option on the stock with a strike price of $230 and one year to expiration costs $5. Suppose that one year later, there is an 40% probability that the stock price will be less or equal to $230, 30% probability that it will increase to $235, and 30% probability that it will increase to $250. What is the expected return of buying a 1-year call option with a strike price of $230?

Problem 1: A rocket of mass $m$ is launched from the surface of the Earth. The rocket is subject only to the effects of gravity (there are no other forces acting on the rocket). Assuming that the rocket travels in a straight line away from the Earth as shown. (a) Write the equation of motion of the rocket. Take the mass of the Earth as $M_E$ and the radius of the earth to be $R_E$. The force of attraction from the earth can be expressed as a force acting on the rocket towards the center of the earth with magnitude $F_g = mg \left(\frac{R_E}{x}\right)^2$ where $g$ is the usual gravity acceleration. (b) The initial velocity with which the rocket must be launched from the surface of the earth (i.e., $x_0 = R_g$) so that it escapes the gravitational attraction of the earth. Note that this requires integration of the equation to find $v$ as a function of $x$ and then substituting $v = 0$ as $x \to \infty$. $\vec{r} = x\hat{i}$
