    Black-Scholes Formula in Switzerland

    You are based in Switzerland. You own two call options both maturing in one year: call option to buy USD at strike 1.2200 CHF/USD and call option to buy EUR at strike 1.5200 CHF/EUR. Spot CHF/USD is 1.2255 and spot CHF/EUR is 1.5255. Which of the option costs more?

    Assets/variance/portfolio question

    B. Assume there are only two assets in a portfolio. If this portfolio has a positive weight for each asset, can its (portfolio.s) variance be greater than the variance of returns on the asset in the portfolio that has the higher variance of the two? Explain. Can the variance of the portfolio be smaller than the variance of retur

    Federal Reserve problem

    Suppose that the Federal Reserve lowers the required reserve ratio from 0.10 to 0.05. How does this affect the simple money multiplier, assuming that excess reserved are held to zero and there are no currency leakages? What are the money multipliers for required reserve ratios of 0.15 and 0.20?
