(*) Swensen specifically calls for 15% TIPS as part of the bond portion of the portfolio. I don’t have good data for that asset, so I added it to the overall ITB allocation. Be sure to read Swensen’s explanation for why he chooses the assets he does.
Because verified data is not available, this portfolio includes estimated returns prior to 1972. Data for those years is highlighted on each chart.
