The $[K]-strike put with [d] days until expiration has a premium of $[P]. The underlying currently trades at $[S]. What is the maximum loss a trader can suffer if they hold a long position in option until expiration? Enter your answer as a dollar amount, rounded to the nearest $0.01. Assume 252 trading days in a year. If the option’s net payoff is unbounded, enter 1,000,000.

A trader takes a long position in 2 call option contracts on NFLX, each with a premium of $5.00 and a contract size of 100 shares. The trader pays $1,000 in initial capital.

Challenge The option margin requirement we’ve used this semester (see the equation sheet) is just one of two formulas that brokers may use to determine how much margin a trader must post to open a short position. Brokers calculate both requirements and then require the trader to post the greater of the two. To see why this matters, consider the following situation that arises with our margin requirement formula. You are in bearish on the volatility, but bullish on the price of McDonald’s stock (ticker: MCD), whose current spot price of MCD is $[S]. Under our option margin requirement, what strike price should you choose such that you would not have to post any margin (beyond the option’s price)? Enter your answer as a number of dollars per share, rounded to the nearest $0.01.

Consider a [K]-strike call that expires in [days] days whose price is currently $[C]. The underlying’s current spot price is $[S] and the risk-free rate is [r0] percent per year, continuously compounded. The underlying does not pay a dividend. Before any time can pass, the risk-free rate falls by 1 percent. If the underlying’s spot price does not react to the fall, what is the new call price immediately after the interest rate fall? (Hint: the risk-free rate only affects the option’s time value.) Enter your answer as a number of dollars, rounded to the nearest $0.01. Assume a year has 252 days.
