Courtesy of I appeared last Friday on a the PBS program WealthTrack, where the topic was asset allocation, in particular, as host Consuelo Mack put it, how to build an all weather portfolio. I was the skeptic of the group. I don’t think there is some magic asset allocation that protects you from the buffetings of financial storms without it also trimming your sails during fair weather. Here is an encapsulation of my views from the program.
Asset allocation and risk appetite
One of the participants, asset allocation guru David Darst of Morgan Stanley, proposed various portfolios to protect against a 100-year flood, 30 to 70-year flood, a 25-year flood, etc. Those portfolios boiled down to putting less in risky assets and more in bonds; the more severe the flood you anticipate, the less risk you take. Of course, that will do the trick. If by asset allocation you mean determining where to set your risk tolerance dial, we’re all on board.
Asset allocation is like clapping with one hand
But the discussion of risk tolerance highlights that we can only go so far with asset allocation if we only look at assets. What matters is assets versus liabilities, because the liabilities determine our risk tolerance and, related to that, our demand for liquidity. It is impossible to formulate an ideal asset allocation strategy without knowing the liability stream those assets are intended to meet. There is no one-size-fits-all for asset allocation. This reminds me of an FAJ article I did back in the 1980s with pension actuary Jeremy Gold entitled “In Search of the Liability Asset”.
Diversification works well, except when it really matters
We all know the argument from Finance 101: If you hold 16 uncorrelated assets, your risk will drop by a factor of four. Well good luck with that.
During a crisis, when diversification really matters, correlations aren’t near zero (as if they ever are). All that people care about is risk and liquidity. All assets that are highly risky drop, all assets that are less liquid drop. No one cares about the subtlety of earnings streams. It is like high energy physics. When the heat gets turned up high enough, matter is just matter, the distinctions between the elements is blurred away.
This is not to say
