Problem 1610 Hedging with Options (LO3, CFA3) Suppose you have a stock market portfollo with a beta of 75 that is currently worth $754 million. You wish to hedge against a decline using index options. Describe how you might do so with puts and calls. Suppose you decide to use SPX calls. Calculate the number of contracts needed if the call option you pick has a delta of 50 , and the S\&P 500 index is at 1,270. (Do not round Intermediate calculations. A negative value should be indicated by a minus sign. Round your answer to the nearest whole number.)
