When I calculated it on excel, my p$/$e ratio was $5\mathrm{.}764809$ and my p$/$sps ratio was$-1\mathrm{.}18986.$ This is apparently incorrect because the question says $"($Exclude negative annual PE and P$/$CFPS ratios from the average PE and average P$/$CFPS ratio calculations. When computing annual growth rates, use a positive sign on the annual rate of change if the per share value increased in value and use a negative sign on the annual rate of change if the per share value deceased in value.$)\text{'}.$ I do not know how to do this which is why I$\text{'}$m asking this question.
