How efficient is a given portfolio?

[letsgobobby]

How does one calculate the efficiency (is that the same thing as a Sharpe ratio) for his own portfolio? Swedroe illustrates this in one of his books. Ie, add some small stocks, add some value, add some REITs, etc., improve efficiency.

For example my portfolio is 60/40, but tilts small/value and half of fixed income is stable value. How do I take that info and calculate its efficiency compared to TSM/TBM in a 60/40 ratio?

The goal is to ensure the highest possible returns for a given level of volatility, or alternatively to maintain a given level of expected returns while ratcheting down volatility.

This may be far enough in left field as to be OT. I'm assuming you have an intellectual curiosity beyond the mere optimal MV calculation task. You may find this paper enlightening [regarding portfolio efficiency]. It may be beyond what you're looking for but contains methodology that is helpful to the task.

This isn't light reading....
