As I set out when explaining my Investment Policy Statement, I am a big believer in diversification. But I also know that you should only invest in what you know, and you can’t know everything; as Warren Buffet put it, “Wide diversification is only required when investors do not understand what they are doing.“. How to strike a balance between having enough skin in the game when I have conviction, and having enough diversification to allow me to sleep at night?
An investment here, an investment there, and pretty soon you’re talking a lot of holdings
My own investment portfolio, which is a mixture of ETFs and direct holdings, and which covers a range of countries, contains more than 200 underlying holdings (see graph below). (Note: I say underlying holdings because I hold some securities in multiple accounts. I consolidate my overall picture every month into one spreadsheet which aggregates by underlying holding).
