Diversification by asset class, sector, country, and currency is important when putting together a portfolio... It is better to choose a management company that will tell you where and how much money to invest. ISEC seems to be a good choice. My friends there were successfully started an investment portfolio, and now they get good profits here. it is possible to choose the type of account with the most suitable for your aims. One friend has chosen the most risky type of investment with the highest return, so far everything is going pretty well overall. Mine is giving lower returns but under current conditions it performs better than SnP500
