The spot exchange rate of dollars per euro is 0.95.Dollar and euro interest rates are 7.0% and 6.0%,respectively.The price of a $0.93 strike 6-month call option is $0.08.What is the price of the put?

Rankin Corp.common stock is priced at $74.20 per share.The company just paid its $1.10 quarterly dividend.Interest rates are 6.0%.A $70.00 strike European call,maturing in 6 months,sells for $6.50.How much arbitrage profit/loss is made by shorting the European call,which is priced at $2.50?

Jillo,Inc.stock is selling for $54.70 per share.Calls and puts with a $55.00 strike and 40 days until expiration are selling for $1.65 and $1.23,respectively.Draw a profit and loss graph illustrating the arbitrage.

The 6-month call and put premiums are $0.114 and $0.098,respectively,with a $0.94 strike.Dollar and euro interest rates are 7.0% and 6.0%,respectively.What spot exchange rate is implied by this data?

Explain in simple terms why a call option on a non-dividend paying stock should never be exercised early.

The necessary condition for early exercise is that we prefer to receive something sooner rather than later.With a dividend paying call and a non-dividend paying put,what do we receive?

Put-call parity allows a discussion of option pricing relationships without actually pricing an option.Have the class list all the possible pricing relationships they can recall.Add to the list until reasonably complete.Follow up this exercise by listing puts and calls,while asking students to state if certain premiums are possible.

Jafee Corp.common stock is priced at $36.50 per share.The company just paid its $0.50 quarterly dividend.Interest rates are 6.0%.A $35.00 strike European call,maturing in 6 months,sells for $3.20.What is the price of a 6-month,$35.00 strike put option?

A company is forecasted to pay dividends of $0.90,$1.20,and $1.45 in 3,6,and 9 months,respectively.Given interest rates of 5.5%,how much dollar impact will dividends have on option prices? (Assume a 9-month option.)

The price of a stock is $52.00.Lacking additional information,what is your forecasted difference between a put option and a call option on this stock? Assume 38 days to expiration and 6.0% interest.
