Compare Vanguard Portfolios
Visually comparing past performance of popular model portfolios is only a few clicks away. You can select an entire group of portfolios to backtest, or simply select the individual portfolios you are interested in and click the Compare button at the bottom. Since the backtest program runs in JavaScript on your web browser, the more portfolios you select, the longer it takes to get results. Your mileage may vary.
Past performance is no guarantee of future returns. Increased risk provides no guarantee of return.
