ENVISION METHODOLOGY: Based on accepted statistical methods, the Envision tool uses a simulation model to test your Ideal, Acceptable and Recommended Investment Plans. The simulation model uses assumptions about inflation, financial market returns and the relationships among these variables. These assumptions were derived from analysis of historical data. Using Monte Carlo simulation the Envision tool simulates, different potential outcomes over a lifetime of investing varying historical risk, return, and correlation amongst the assets. Some of these scenarios will assume strong financial market returns, similar to the best periods of history for investors. Other will be similar to the worst periods in investing history. Most scenarios will fall somewhere in between.
