Can anyone explain what the examiners' report means by "standard interpolation"?
I would have approached this question by calculating two values for the call option price, first using sigma=0.2, and then increasing or decreasing appropriately, and then interpolating. But mark allocation for this seems to be very stingy - only 2 marks! Implying that I should be able to do all this in around 3.6 minutes!!!
In previous papers there was usually around 5 marks for this type of question.
Is there a quicker way of doing this? Any ideas?
Thanks!
