Hi

I wanted some help regarding earnings per share forecasting. I have a assignment about Britsh American Tobacco and their fiscal year is from 1 jan to 31 december and has it headquarters in UK. In this assignment I am looking at random walk and if it is as good as other forecasting methods. So I am comparing Random Walk to Money Supply m4 (broad money) model and looking at which one of these models is better or can give more accurate forecast. My question is that I have been given money supply model numbers in Pounds . And in uk money supply models fiscal year is from may to april.

British American Tobacco fiscal year is from january to 31st december. Should I also use January and december number for money supply model or should I take the companys number from may to april so that the companys fiscal year will be the same as money supply model when I calculate the yearly earnings per share forecast?
