What amount of companies or what $ size of your portfolio did you get to until you started buying overseas shares to diversify a bit and benefit from other economies other than Australia?
eg. Porfolio size got to 50k. You had invested in 3 ASX companies and then decided to buy 20k worth of shares in US or UK markets.
Just saying that ASX is heavily weighted in mining and financials and companies in overseas markets have exposure to a lot of different industries.
