Sharpe Ratio: A measure that indicates the average return minus the risk-free return divided by the standard deviation of return on investment.Max Drawdown: A maximum drawdown (MDD) is the maximum observed loss from a peak to a trough of a portfolio before a new peak is attained. Maximum drawdown is an indicator of downside risk over a specified time period.Sortino Ratio: The Sortino ratio is a variation of the Sharpe ratio that differentiates harmful volatility from total overall volatility by using the asset's standard deviation of negative portfolio returns—downside deviation—instead of the total standard deviation of portfolio returns. The Sortino ratio takes an asset or portfolio's return and subtracts the risk-free rate, and then divides that amount by the asset's downside deviation.Upside Risk: This is the maximum upside scenario outcome taken from selected scenarios.Downside Risk: This is the maximum downside scenario outcome taken from selected scenarios.5-Year Expected Return: The system first calculates the expected return for the portfolio by calculating the one-year weighted average return across all expected scenarios. Then, the one-year expected return is compounded to obtain a 5-year return estimate. Historically, major downside events occur roughly twice a decade, so this is an appropriate timeframe for comparison of long-term returns and downside scenario risk. Correlation Risk: The number at center is a measure of both correlation and concentration risk, computed based on the portfolio's full correlation matrix. The metric ranges between 0 and 1, with 0 representing an infinite number of perfectly uncorrelated positions and 1 being any number of perfectly correlated positions. Single position portfolios receive no scores, as there are no positions to compare against.
