Hello: what is the best way to determine the 5-year average growth rate of a series of annual EPS numbers that are negative and become less negative with time? For example:

-79.23 -55.32 -47.29 -2.64 -1.72 -1.93 -0.39 -0.03

Some kind of CAGR is actually more what I am looking for but I’m unsure this can be done with negative numbers. My best haphazard guess of obtaining some kind of usable answer is: 1) determine the %-change between years, 2) determine average of the %-changes

Any help is appreciated! Thanks!
