While publicly traded stocks, bonds, and real estate have their prices constantly adjusted throughout the day, leading to lots of volatility<\/a>, private capital managers have significant discretion as to when and how they mark-to-market or mark-to-model their portfolios (typically valued quarterly). Because their valuations are less frequent, private equity returns appear smoother. If the \u201clagged betas\u201d are not considered, investors will underestimate the risks of private investments, leading to an over allocation.<\/p>\n\n\n\n

The Evidence<\/strong><\/p>\n\n\n\n

Nicolas Rabener, author of the 2020 study \u201cPrivate Equity Is Still Equity, Nothing Special Here,<\/a>\u201d found that the volatility of private equity returns is understated as a result of smoothing, and the risk-adjusted returns are comparable to those of public equities. An unsmoothing approach results in comparable standard deviations of returns for private equity. He also found that U.S. private equity returns could be replicated systematically through public equities, historically by selecting small, cheap and levered stocks. Since small value stocks are significantly more volatile than the overall stock market, the implication is that advisors including allocations to private equity in client portfolios should increase their volatility assumption to about 20% greater than for public equities.<\/p>\n\n\n\n

Underestimating risk by not considering lagged betas is not the only problem. Failure to consider what has been called \u201cvolatility laundering<\/a>\u201d also leads to underestimating the correlation of private investments to public ones, and overestimating the alphas of private assets.<\/p>\n\n\n\n

New Evidence<\/strong><\/p>\n\n\n\n

To analyze the impact of lagged betas on private assets, Mark Anson, author of the 2024 study \u201cAmortizing Volatility across Private Capital Investments<\/a>,\u201d published in The Journal of Portfolio Management (Volume 50, Issue 7), extended the research beyond private equity and venture capital to include secondary private equity, private credit, and private real estate investing. Anson expanded the examination of lagged betas to include not only systematic market risk, but also the full body of Fama\u2013French factors (market beta, size, value, momentum, investment, and profitability). His data sample spanned the period 1998 through 2022.<\/p>\n\n\n\n
