Thanks for your comments Cazzex, 3500, J8 and GoSouth.
At the moment the spreadsheet just picks the top well correlated stocks of each sector. To help remove the bias this may cause I am looking at dividing up the sectors. Maybe someone can offer a better split up of the below
An example:
Mining Services divided into "
Drilling ASL IMD SWK Campbell Bros
Build,Own and Manage
Sedgeman Decmill Monadelphous
Engineering and Consultancy
Cardno Lycopodium Skilled group Programmed Campbell Bros
Construction
Leighton MacMahon NRW Austin Boom
Logistics
Bradken Mermaid Miclyn Express
Gosouth, I can easily change the graphite companies and when I get back to my other computer with the excel spreadsheet I will post the new results.
