Depreciation = value originally with the year (opening harmony) + buys while in the yr − value at the conclusion of the yr (closing stability)
You can even analyse the skewness and kurtosis with the interval PnL by having 3rd and 4th moments of $Y_t$ respectively. Presumably you'll conclude that for two series with identical expectation and variance, you are going to choose the just one with beneficial skew or decreased kurtosis, but maybe not according to the self-assurance of the marketplace check out, and many others..
