And so the mean of this is the mean of a lognormal random variable with the log mean as $\ln S_0 + \mu T - \frac{1}{2}\sigma^2T$ and the log standard deviation as $\sigma \sqrt{T}$, and so the ...

The NYSE used to maintain a post for companies that did not trade weekly not so long ago. However, unless you have cause to believe there was a reason for it to ...
