For any set of investments, there are many ways to combine them (i.e. to allocate money between investments) and each combination (set of weights) will produce a different expectation of total portfolio return and a different portfolio volatility. This section shows the risk-return position for your total portfolio using its original asset allocation and many other potential portfolio positions. Some may give a higher or lower expectation of return; some may give a higher or lower risk.
You are the best person to decide where your portfolio should be to help you achieve your goals. Diversiview gives you insight and calculates that position.
