I'm creating portfolios in excel and I want to sort them by matching company numbers from Datastream. I want to sort them in upper and lower median of market value and another component which will create a matrix with six different portfolios. Do I have to "match" every company number by myself or is there an easier way to do this in excel, or in any other programme that Windows offers? With company number I mean the number that a company gets in Datastream which is converted into an excel-file.
