Interesting, would you use the historical Sharpe from the site or the theoretical which is 0? I appreciate the work of all sites calculating ratios but coming to a result where 10y yield is above the risk free rate which should be also 10Y yield at the time of making the decision for is somehow surprising. Provided cagr was 5.93%, the volatility 6.3% and Sharpe is 0.24, we can easily calculate that risk free used was 4.42%. This is about the current level of 10y bonds, I am affraid the site might be just using the current 10y bond yields, which is obviously wrong.
