A stock is priced at $30/share.  The interest rate is 7%/year.  A three-month European call option with a strike price of $35 has a Black-Scholes price of $.28

b. The delta of the call is .1515.  How would you make a synthetic call (i.e., how many shares and how many dollars in T-bills)?

c. What is the delta of an otherwise identical put?  How would you make a synthetic put?

d. If a trader sold 100 calls, what share position would he/she need to take to be delta neutral?

e. Suppose the gamma of the call is .0625. If the stock price increases by $1, how does the delta change?  If the stock price increases by $3, does the hedged position make money or lose money?
