c) A risk-neutral competitive market maker clears the market for trading in a stock after observing the incoming orders from a noise trader and an informed trader (who perfectly knows the true value of the stock). The noise trader buys and sells 1 share of the stock with equal probability, whereas the informed trader buys the stock if the value is $14 (high) and sells the stock if the value is $5 (low). The market maker believes initially that there is a 45% probability of high value and a 55% probability of low value. What profits can the informed trader expect to make in this market?

Over the long run will your strategy outperform, underperform, or have the same return as a buy and hold strategy of investing in the market portfolio? Would your answer to part (a) change if all traders in the market were equally well informed and were equally skilled?
You meet with two investors who have different expectations for stock CBD that can be addressed with various positions in puts, calls, and the underlying stock (or combination).

Investor A already holds CBD stock and wants to lock in gains if the stock drops below its current levels, while maintaining upside exposure. b. Investor B wants to profit if CBD’s upcoming earnings announcement is either unexpectedly good or disappointingly bad. c. Investor C already holds CBD stock and believes the stock will not increase much in the near term. As such, she wants to earn some extra income using options.

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?
