When investfit projects future outcomes it uses a stochastic engine instead of a deterministic engine as in a spreadsheet model. The deterministic approach means the adviser or dealer group “determines” the investment market returns assumptions to forecast future outcomes. The problem with this approach is that these assumptions are static and this can lead to overly optimistic projections that underpin advice.
However a stochastic engine allows us to factor in the fact that markets go up and down and so market returns also go up and down. This gives us a far more robust projection and quality of advice. We can also measure how certain we can be of a particular outcome. Stochastic routines are used in many industries.
