Abstract

Alternative assets have become as important as equities and fixed income in the
portfolios of major investors, and so their diversification properties are also
important. However, adding five alternative assets (real estate, commodities,
hedge funds, emerging markets and private equity) to equity and bond
portfolios is shown to be harmful for US investors. We use 19 portfolio models,
in conjunction with dummy variable regression, to demonstrate this harm over
the 1997–2015 period. This finding is robust to different estimation periods,
risk aversion levels, and the use of two regimes. Harmful diversification into
alternatives is not primarily due to transactions costs or non-normality, but to
estimation risk. This is larger for alternative assets, particularly during the credit
crisis which accounts for the harmful diversification of real estate, private equity
and emerging markets. Diversification into commodities, and to a lesser extent
hedge funds, remains harmful even when the credit crisis is excluded.
