Backtest Portfolio Asset Class Allocation

This portfolio backtesting tool allows you to construct one or more portfolios based on the selected asset class level allocations in order to analyze and backtest portfolio returns, risk characteristics, drawdowns, and rolling returns. You can compare up to three different portfolios against the selected benchmark, and you can also specify any periodic contribution or withdrawal cashflows and the preferred portfolio rebalancing strategy.

You can also use the portfolio backtesting tool to build and compare portfolios based on specific mutual funds, ETFs, and stocks.

  • The results do not constitute investment advice or recommendation, are provided solely for informational purposes, and are not an offer to buy or sell any securities.
  • The results are based on the total return of assets and assume that all received dividends and distributions are reinvested.
  • CAGR = Compound Annual Growth Rate
  • TWRR = Annualized time weighted rate of return
  • MWRR = Annualized money weighted rate of return (internal rate of return) taking into account the periodic cashflows
  • Stdev = Annualized standard deviation of monthly returns
  • Sharpe and Sortino ratios are calculated and annualized from monthly excess returns over risk free rate (3-month treasury bill)
  • Stock market correlation is based on the correlation of monthly returns
  • Drawdown analysis is calculated based on monthly returns excluding cashflows
