Too Many Other Asset Classes?
SPONSOR: http://www.MarcinkoAssociates.com
[By Dr. David Edward Marcinko MBA MEd CMP™]
Some financial analysts believe that the focus on asset classes may have gone too far as physicians and other investors have sought to “over optimize” their portfolios.
In fact, colleague David Loeper, CEO of Wealthcare Capital Management, explained this concept as follows:
“Where things have really got off track has been the insistence on breaking asset classes into sub-classes by style, market capitalization, etc. The unpredictability of all the inputs into our optimizers, even over long periods of time, has been ignored. We have attempted to take efficient portfolios of stocks, bonds and cash and make them even more efficient by breaking the unpredictable asset classes into even less predictable sub-classes. This has all been done into the pursuit of “efficiency” as the proposal was validated by the Brinson & Beebower study, which purports to find that over 90% of the investment return variance is explained by asset allocation. The risk that you produce inefficient portfolios INCREASES if you increase the number of “asset classes” for which you must forecast not only the risk and returns but also each asset class’ correlation to the others.”
Assessment
If true, and I think it is a valid point, the results of the optimizer and your resulting portfolio’s efficiency is based on the accuracy of the inputs and NOT THE NUMBER OF THE INPUTS.
Or, is this like the TNTC situation in cell cultures and microbiology [Too Numerous To Count].
