giving percentages to (overall negative) revenue growth performance
I have a sampling problem, for an analysis i have to calculate a revenue growth share. I found an article about sampling with negative numbers very helpfull since i have to work with a sum of revenues that is negative. The article suggests to make all the number absolute, but unfortunately this does not solve my problem. Since i am looking at revenue growth shares i want to punish the companies that score 'bad' and reward the companies that score 'good'. therefore it would not make sense for me to gives the same growth percentages (50%) to a score of +1 and -1 in revenue growth.

Simplified; the problem looks as follow;
sample (revenue growth)= 2, -3, -4, -1

sum=-6

scenario 1 calculated percentages;

2/abs(-6)

-3/abs(-6)

-4/abs(-6)

-1/abs(-6)

is this correct or should i take this approach;

2/10

-3/10

-4/10

-1/10


I have the problem that both scenario's do not add up to 100%. I need the growth share to calculate z scores. I hope you have a suggestion.

Thank you very much in advance,

Kind regards,
