An investor is considering purchasing a share of stock. Earnings are expected to be $6 per share and the price next year is expected to be $100. Suppose risk-free interest rates fall and the required rate of return decreases from 7% to 6%. Nothing else changes. What is new price the investor is wiling to pay for the stock? Answer in dollars and do not enter a $ sign. Round to two decimal places.
please explain step by step
Momo, a fast-growing company, will make an earnings announcement three months from now. But you do not know whether it will be positive or negative (i.e., the stock price will go up or down). The current price of the stock is $30 per share. A three-month call with an exercise price of $30 costs $5. A put with the same exercise price and expiration date costs $5.
a. What would be a simple options strategy to bet on the stock price volatility?
You expect the price of a stock to increase by 20% in the following year, with a standard deviation of 30%. The stock currently trades at $50. You pursue a strategy of buying 100 shares of the stock on margin. The initial margin requirement is 50%. The annual interest on margin debt is 5% per year.
(a) What is the expected return and standard deviation of your strategy? (assume there is no margin call.)
(b) The maintenance margin is 30%. Six months after you establish your trade, you receive a margin call. What is the price of the stock when this happens?

Over the next 8 months, the stock that you shorted has a return of -23%. What is the EAR of your investment? The easiest way to do this one is to start with the multiplier, then apply it to the return on the asset to get the return on your equity, then annualize that return. The correct answer is: 1.20arrow_forward

- Stanton Company stock is trading for 50 in a two‑time period environment, so that each relevant time period is 6 months. The stock might increase by exactly 20% in just one period or perhaps in both periods. Of course, the stock might not increase in either period. If the stock price does not increase in a given period, it will decline by 16.67 percent in that particular period. One-year options with an exercise price equal to 60 are trading on this stock. The annual riskless rate of return equals 0. a. What is the value of a put in this environment? b.
