This is one of the proprietory processes developed by the investfit team. The process involves simulating the outcome of a large number of investment strategies (potentially up to 10,000) and simulating each strategy thousands of times. Each simulation represents a different but possible set of investment returns that might be expected based on the behaviour of investment markets. Investfit does this each time you regnerate a set of results for your client and each time identifies the strategy that leads to the best outcomes. This is the optimal investment strategy.
