Problem: Write a memo that talks about the differences in buying a call option, selling a call option, buying a put option, and selling a put option. Please give an example of a business scenario that would be appropriate to use in each of the contracts (put and a call contract). If one were to choose to use the forward market and were to receive 100,000 Japanese yen in roughly six months, and the current exchange rate was 5 yen equalling 1 US dollar, then with that information, how many yen would one sell or buy in the forward market?
