If we create a portfolio invested 50% in VDBA and 50% in VDGR we can simulate a 60/40 passive benchmark:
This requires monthly rebalancing of the portfolio. We ignore the costs of this rebalancing. Over this period, the benchmark portfolio had a compound annual return of 5.60% with a monthly standard deviation of 2.55% compared to Moom's compound return of 7.77% with a monthly standard deviation of 2.32%. Moom's beta to this portfolio was 0.8 with an annual alpha of 2.9%.
Note that our portfolio goes through three different "regimes" during this period. Up to October 2018 we had a portfolio that was about 60% long public equity. Then we received a large amount of cash, which we converted to bonds and then gradually invested in other assets. This phase lasted up to the end of 2020. Since then we have been close to the target portfolio.
