As you want a rank, I suggest the use of -egen, rank()-. 

-egen, group()- is only going to produce an equivalent result if there
are no ties. 

You get rank of 1 for highest by negating the variable: 

drop rank 
egen rank = rank(-revenue) 

This point and related stuff are discussed in

I am trying to create 'rank' based on total revenues. I used the following 
command:

sort revenue
egen rank=group(revenue)

The result is that the smallest revenue is 1 and the highest revenue is 100, 
for example. How can I reverse the rank? I want the highest revenue to be 
number '1'.
