Hi, just have a few questions on this chapter. Why is the vega of a share equal to zero? Do we need to know how to derive vega and theta? (This was examined a number of years ago though not sure if it is on the 2017 course?)

There have been no changes to the course that prevent a derivation of vega or theta being examined. As you say, this has been examined in the past, but it's been a number of years now since questions were set on this. The thread at the top of this forum (called "The Greeks"), has some useful information in it if you're looking at this material on deriving the Greeks.
