IMPORTANT - Referencing 2 files in the same formula

["Luigi Rolando Baldoni" <baldoni@xxxxxxxxxxxx>]

I don't understand why nobody be in a position to 
solve my problem of referencing 2 files in the same formula. I see that usually 
all of us manage very complicate problems. I think that the question I have 
asked is rather usual and important. How to compare for instance 50-100 stocks 
with Nasdaq or Dow. I think that we have to reference 2 files in each comparison 
and the solution to turn to composite files is absolutelY inadequate. Can some 
friend of our Group help me in this interesting problem? Thanks.
