The average annual yield is calculated as the geometric average of gross returns for individual years of the investment period. This figure accounts for compound interest rates (i.e. a reinvestment of portfolio returns) as well as possible fluctuations of returns over the investment period, therefore is suitable to represent a portfolio performance.

The overall yield is an actual (gross) rate of return on investment over the investment period. The overall yield accounts for compound interest, capital gains and dividends.

A benchmark is generally an index against which a performance of a comparable fund or a portfolio is compared to. Hence benchmarks for individual WEM portfolios differ based on their specifications, risk level and geographical focus.
After selecting a benchmark from a dropdown list, the bottom performance chart will show you an overview of the alpha - the portfolio outperformance over a selected benchmark over a selected investment period.
Portfolios with no available benchmark will only have the "NONE" option available.

Gross performance is calculated as the total return on an investment before fees, commissions and taxes and includes compound interest, capital gains and dividends.
Net performance is gross performance net of fees, commissions, and taxes.

Current performance shows gross performance for the selected investment period.

The upper chart shows the performance of the portfolio for the selected investment period. The bottom chart shows the performance of the portfolio since its inception.
You can also see the current performance on the graph. Please note that the value of current yield on the graphs and the overall yield might not match, as the overall yield is calculated based on a specific and predefined period.
