We now have enough data to compute the rate of return over 8 years on Moominmama's portfolio. This table compares it to the MSCI World Index:
All rates are annualised. In general the portfolio has about half the performance of the MSCI World Index. This isn't surprising given the conservative nature of the portfolio. I estimate beta at 0.47 and alpha at -2.31%. The latter is not very good. The standard deviation of monthly returns is 5.91% for the MSCI for the months for which we have data on the portfolio and 3.3% for the portfolio. So it seems there is a bit over half the risk for less than half the average return and, therefore, a worse Sharpe ratio. So we have sacrificed return for a less than proportionate reduction in risk. Obviously, we could be doing worse than this too. I guess it depends on what your expectations are.
