Warrants are long-term call options that have value because holders can buy the firm’s common stock at the exercise price regardless of how high the stock’s price has risen. explain
A) Assume that you have some shares of stock in ABC Inc. Why do we say that if you also purchase a put option on the same stock, the price paid to buy the put option is like paying an insurance premium?
B) We understand standard deviation of returns as a measure of risk and rational investors would like to minimize risk. Notwithstanding this, you may have read that as the standard deviation of returns of the underlying asset increases the value of an option rises. If standard deviation is a measure of risk and investors do not particularly like it, why does it lead to an increase in an option's value?

- Select all that are true with respect to the Black Scholes Option Pricing Model (OPM) in practice): Group of answer choices BSOPM assumes that the volatility of the underlying stock returns is constant over time. BSOPM assumes that the underlying stock can be traded continuously. BSOPM assumes that there are no transaction costs. There is only one input to the BSOPM that is not observable at the time you are valuing a stock option, and that input is volatility. Implied volatility is estimated by calculating the daily volatility of the underlying stock’s return that occurred over the prior six months.arrow_forwardMy question is for a synthetic call option why do we need to borrow the present value of the strike price and what does it mean in a simple language explanation. Similarly why do we need to lend the present value of the stock at risk-free rate and what does it mean in simple language explanation? Please also clarify the significance of risk free rate? Why is it used in put call parity. Synthetic Call Option: If an investor believes that a call option is over-priced, then he/she can sell the call on the market and replicate a synthetic call. Borrow the present value of the strike price at the risk free rate and purchase the underlying stock and a put. Synthetic Put Option: Similar to the synthetic call option. A synthetic put can be created by re-arranging the put-call parity relationship, if the trader believes the put is overvalued. Synthetic Stock: A synthetic stock can also be created by rearranging the put-call parity identity. In this case, the investor will buy the…arrow_forward2. Call Options A.

Assume that FBN's stock is currently selling for $20 and that over the coming year the price will either rise to $81 or fall to $11. Also assume that the one-year rate of interest is 10 percent.

- Do derivatives markets give participants the beneficial opportunity to adjust risk exposures to desired levels, generate returns proportional to movements in the underlying and/or simultaneously take long positions in multiple highly liquid fixed-income treasury bonds? Explain why one or more of the options above are correct and explain why, if any of the remaining options are incorrect.arrow_forwardTick all those statements on options that are correct (and don't tick those statements that are incorrect). B a. The Black-Scholes formula is based on the assumption that the share price follows a geometric Brownian motion. b. If interest is compounded continuously then the put-call parity formula is P+ S(0) = C + Ker where T is the expiry time. An American put option should never be exercised before the expiry time. d. In general the equation S(T) +(K-S(T)) = (S(T)-K)+ +K is valid. e. The put-call parity formula necessarily requires the assumption that the share price follows a geometric Brownain motion.

- You are given the following information on some company's stock, as well as the risk- free asset. Use it to calculate the price of the call option written on that stock, as well as the price of the put option. (HINT: You should use the Black-Scholes formula!) (Do not round intermediate calculations and round your final answers to 2 decimal places, e.g., 32.16.) Today's stock = $74 price Exercise price = $70 Risk-free rate = Option maturity = 4 months Standard deviation of annual stock returns 4.4% per year, compounded continuously Call price Put price = 62% per yeararrow_forwardProblem 4d: State whether the following statements are true or false. In each case, provide a brief explanation. d. In a binomial world, if a stock is more likely to go up in price than to go down, an increase in volatility would increase the price of a call option and reduce the price of a put option.
