While private equity has delivered higher absolute returns than the S&P and Russell indexes, it also exhibits higher volatility and risk. The illiquid nature of private equity, combined with the leverage often used in buyouts, can amplify both gains and losses. This higher risk is reflected in the greater standard deviation of returns for private equity funds compared to the major indexes.
That said, when adjusted for risk, private equity often still shows a favorable performance profile. Measures such as the Sharpe ratio, which considers both returns and volatility, often indicate that private equity provides better risk-adjusted returns than public equities. This makes private equity an attractive option for investors seeking higher returns with an understanding of the associated risks.
Private equity tends to have a lower correlation with public markets. This lower correlation can make private equity an effective diversifier in a broader investment portfolio. During periods of market stress, such as the 2008 financial crisis, private equity funds often exhibited less dramatic declines than public markets, although they were not immune to downturns.
However, it's important to note that private equity valuations are often smoothed due to the infrequent pricing of private assets, which can understate the true volatility and risk during periods of market turbulence. As a result, the perceived lower correlation may be partially a reflection of the valuation methodologies rather than an inherent stability of the asset class.
Private equity has historically outperformed public market indexes, offering higher returns over the long term. However, this outperformance comes with increased risk, including higher volatility, illiquidity, and the potential for significant dispersion in fund performance. For investors willing to accept these risks, private equity can be a valuable component of a diversified investment portfolio, offering the potential for superior returns and lower correlation with public markets.
Comparing private equity with the public markets highlights the trade-offs between potential returns and associated risks. While private equity has the potential to deliver higher returns, it requires a long-term investment horizon, careful manager selection, and a tolerance for illiquidity and volatility. Investors should carefully consider these factors when deciding whether to allocate part of their portfolio to private equity.
