3. Consider a call on the same underlier (Cisco).
The strike is $50.85, which is the forward price.
The owner of the call has the choice or option to buy at the strike.
They get to see the market price S1 before they decide.
We assume they are rational.
What is the payoff from owning (also known as being long) the call?
