How to create a peer group for valuation

tim-hahn — Thu, 30 Apr 2020 14:15:41 GMT

Thank you very much for taking time to read this post.

I have a column "ICBSUN" with industry classification codes and a separate column "EV/EBITDA" with an EBITDA multiple.

Now I would like to create a new column "Peer Multiple" that takes the Harmonic mean of the "EV/EBITDA" Coulomn of all Companies with the ICBSUC Code 452010 except the one company of the row itself.

So for example to get the first Value in the "Peer Multiple" Column for the table below it should take the Harmonic mean of the rows 2-12 from column "EV/EBITDA".

However the amount of companies companies in each industry varies and may not be sorted like this example.

Can anyone help? Thank you very much! 🙂

Re: How to create a peer group for valuation

So let's start by referring to this example at Wikipedia of the harmonic mean of three numbers.

Here's an outline of how to do this:

You want the sum of the reciprocals of all of the values. You can get this by groups, by first computing the inverse of the ev_ebitda in a SAS data step and them summing these inverses by group using PROC SUMMARY. This will give you the denominator of the entire group harmonic mean, the numerator is of course N for each group. Next, to adjust the harmonic mean by removing one row at a time, again in a SAS data set, you can compute the numerator as N-1 and the denominator as the denominator of the group harmonic mean computed above MINUS the inverse of ev_ebitda for this one row.

Thank you very much @PaigeMiller .

my code now looks like this.

data work.Sas_test;
set work.Sas_test;
EV/EBITDA=EV/EBITDA;
run;

data work.Sas_test;
set work.Sas_test;
KReciprocal=1/EV/EBITDA;
run;

However I am stuck at the point where I group the reciprocals by industry to get the denominator.

data work.Sas_test;
set work.Sas_test;
if ICBSUC = 201030 then NEW=....
run;

do you have any suggestions to finish the code?

Let's back up. You can't have code EV/EBITDA=EV/EBITDA; because variable names can't have a slash in the name (and even if you could, this statement is meaningless and doesn't do anything). Run the code, get it working, then show us where you get stuck.

its just a name as I named it in the excel file one could just call it Multiple

data work.Sas_test;
set work.Sas_test;
Multiple=EV/EBITDA;
run;

data work.Sas_test;
set work.Sas_test;
KReciprocal=1/Multiple;
run;

UNTESTED CODE, assumes sas_test is sorted by icbsuc

data work.Sas_test;
    set work.Sas_test;
    inverse=EBITDA/EV;
run;
proc summary data=sas_test nway;
    class icbsuc;
    var inverse;
    output out=sum_inverse sum=sum_inverse n=n;
run;
data want;
    merge sas_test sum_inverse;
    by icbsuc;
    peer_multiple = (n-1) / (sum_inverse - inverse);
run;
