Answer: Some rules to help remember the way the graphs look: Long calls (graph 4) and long puts (graph 1) have a zero or positive payoff at maturity, so their graphs are always above the x-axis (the axis representing the underlying asset's spot price at maturity, S T ST ). The short option graphs are the symmetric opposite, the graphs are reflected in the x-axis. The payoff is always zero or negative. This makes sense since options, like all derivatives, are a zero sum game: one trader's win is her counterparty's loss. The long call graph has a positive payoff if the underlying asset price goes up. It has a positive slope. The long put graph has a positive payoff if the underlying asset price goes down. It has a negative slope. Question 2 (123) option Below are 4 option graphs. Note that the y-axis is payoff at maturity (T). What options do they depict? List them in the order that they are numbered

(d) 1: long put, 2: short put, 3: long call, 4: short call. (e) 1: short call, 2: long put, 3: long call, 4: short put. Answer: Some rules to help remember the way the graphs look: Long calls (graph 3) and long puts (graph 2) have a zero or positive payoff at maturity, so their graphs are always above the x-axis (the axis representing the share price at maturity, S T ST ). The short option graphs are the symmetric opposite, the graphs are reflected in the x-axis. The payoff is always zero or negative. This makes sense since options, like all derivatives, are a zero sum game: one trader's win is her counterparty's loss. The long call graph has a positive payoff if the underlying share price goes up. It has a positive slope. The long put graph has a positive payoff if the underlying share price goes down. It has a negative slope. Question 3 (387) real option , option

One of the reasons why firms may not begin projects with relatively small positive net present values (NPV's) is because they wish to maximise the value of their: (a) Expansion option.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
