comment Is Geometric Brownian Model suitable for long term price forecast?
The reason why GBM would be better short-term than not long-term is not obvious to me. Did your professor justify his claim by something? Besides, GBM models asset prices (not returns), were you expecting these to be stationary?

comment How to calculate the growth rate of a growing annuity?
Unfortunately, this is a basic finance question and this site is dedicated to professionals/academics in quantitative finance. You can try your luck in forums dedicated to the CFA curriculum, for example.

comment What does it mean to be “long or short in volatility”?
@emcor negative vega? I don't think that's possible, is it? I mean, the whole idea is that you can replicate an option payoff by holding a portion of the stock and that portion of the stock is determined among other things by volatility I understand. The more volatility the more of the Stock you need to hold and the more the option is worth then right?
