Discover the potential benefits of private investments for your diversified portfolio, their illiquidity premium, and the importance of a financial plan.
Incorporating private investments into your portfolio begins with a solid financial plan. Given their illiquid nature and the potential lack of early exit opportunities, careful planning is essential when considering private markets. Private investments can leverage the “illiquidity premium” to potentially achieve higher returns than public markets, if investors are comfortable with investment capital being locked up for the long term.
Public investments (stock, bonds, mutual funds, ETF’s) typically trade daily and are then available as cash the next day. Money market funds and higher-grade bonds that mature under twelve months generally have the benefit of lower volatility (or nearly none in the case of a money market fund), in addition to the liquidity to turn them into cash. Equity-based investments, directly or through an investment vehicle such as an ETF, should have at least a five-year time horizon in our view, but are available as cash the next business day after the sale. With many private investments, they do not trade daily or at all. Therefore, investors typically require an additional potential for return if they are locking up capital in a private investment that is not liquid. The additional return potential is referred to as the “illiquidity premium” and is the expected difference in return between a private investment and its corresponding public investment.
A discussion about a diversified investment portfolio would not be complete without considering private assets.
While some investors may prefer the liquidity provided by public securities, qualified investors willing to allocate a portion of their portfolio to illiquid securities can potentially benefit from an “illiquidity premium.” Including private investments offers an additional allocation choice that, when combined with effective cash flow management, can enhance diversification and/or returns. Historical data shows that private equity and private credit have outperformed their corresponding public counterparts (U.S. public equities versus private equity and private credit versus U.S. high-yield bonds).3,4
It is important to note that access to private markets is typically restricted to accredited investors, qualified clients, or qualified purchasers. This ensures that only those with sufficient financial resources can participate, given the higher risks and complexities involved in private investments.

Private investments are available through various asset classes:
Various investment vehicles provide access to private markets, each with distinct levels of liquidity:
Due to the risks and illiquidity associated with private investments, the Securities and Exchange Commission requires private investors to meet certain criteria:
While private investments can add diversification and potentially enhance returns, it is crucial to begin with a well-built financial plan to understand your net worth and cash flow needs. Unlike stocks, bonds, ETFs, and mutual funds, which offer daily liquidity and potential capital gains, private investments may require a commitment of up to 10 years. Therefore, planning for this time horizon is essential. Private investments should be considered as long-term vehicles rather than short-term income or growth options.
