Bill Fawkner-Corbett, Head of SIGnet, takes us through his journey of discovering Compounders and the reasons for investing in them. He gives one example of a mistake he made selling Microsoft, which made him realise he had no effective tool for valuing Compounders. In his subsequent reading, he discovered the Graham Formula, which gave him a method for calculating the PE ratio for a company based on growth. This set him on a search for alternative methods that would take account of other metrics (e.g. return on capital) in the PE calculation; his explanation of what he found is fascinating. Although all the examples he gives in the presentation are US shares, the majority of Bill's portfolio is in UK shares – he stresses that more than a few of these he considers to be Compounders. This is a presentation Bill gave to his SIGnet group and is an example of the material that might be covered by your local SIGnet - Serious Investor Group Network.
