20 percent. 3, the fund’s total volatility then depends on the chosen β-value. 20 percent α-risk. As the target β-value rises, the total volatility increases, but the incremental role of the α-risk declines. 9, the α-risk drops to less than 10 percent of the total risk. S. equities. Under these simplified conditions, the portfolio’s total volatility is determined by the α-risk and the target β-value. In turn, the basic α-risk itself is a function of how many independent asset classes are represented in the 60 percent nonstandard allocation.
Once again, the unconstrained optimizer assigns no weight to standard assets. Even more, changes to the asset weights relative to Portfolio C are difficult to understand without deeper analysis. In sum, neither B , C , nor C would make sense in most institutional settings, nor would they be easy to explain to an investment committee. As we will see in subsequent chapters, one way to deal with the challenges of asset-class inputs, portfolio stability, and other issues is to torture the modeling process by imposing piecemeal constraints, adjusting inputs, and other fixes that make the resulting portfolios more palatable.

S. institutional market. S. equities, a value that lurks hidden within virtually every asset class, and that, in aggregate, accumulates to become the portfolio’s overall exposure to the equity market. Once these underlying beta values are uncovered, it becomes clear that many portfolios that appear quite different on the surface in fact share common risk characteristics.
