Private equity can offer exposure to companies and opportunities that are not available in the public markets. Let’s explore the role private equity can play in your portfolio and whether it aligns with your goals.

  • Private markets make up a growing part of the global investment landscape.
  • Vanguard’s research suggests that private equity funds, managed by top-tier investment teams at a reasonable cost, can enhance investor outcomes. The optimal allocation depends on your circumstances, risk tolerance, and individual goals.
  • Liquidity needs, investment horizon, manager selection, and tax considerations are important factors when evaluating the asset class.
  • Vanguard’s research evaluates private equity allocations as a share of total equity exposure rather than a percentage of an investor's overall portfolio.
  • Working with a financial professional can help determine whether private equity fits within a broader financial plan and how much exposure may be appropriate.

 

What about private markets has changed?

Private equity is a growing segment of the global equity markets and represents some of the fastest and most innovative companies in the world today. In fact, there’s a chance you work for a privately held company that otherwise isn’t investable for the average person.

As the private markets have expanded, investors now have access to a wider variety of investment options within the asset class. This makes it increasingly important to evaluate which structures, if any, best align with each investor’s goals, portfolio and liquidity needs, and risk tolerance.

How should I begin evaluating the asset class?

Private equity can be a valuable part of a portfolio for the right investor, offering the potential for higher long-term returns and exposure to opportunities beyond public markets. As interest in private markets continues to grow, more investors are exploring how private equity can complement their overall wealth strategy.

For many ultra-high-net-worth investors, private equity introduces considerations including longer investment horizons, varying liquidity profiles, less frequent valuations, and specialized tax reporting. Partnering with a financial professional can help you evaluate how private equity could fit into your portfolio and investment goals.

What are some key considerations to evaluate?

Evaluating private equity opportunities may require additional due diligence compared with traditional public market investments. Understanding these considerations can help determine the appropriate role private equity can play in building a diversified portfolio to achieve your investment and legacy goals.

Cash flow timing

  • Initial investment is committed up front but invested over years. Rather than investing all at once, capital is typically requested from investors as opportunities are identified over several years.
  • Liquidity is limited throughout the investment life cycle. Returns are generally realized through distributions when portfolio companies are sold, merge with another company, or become publicly traded. Because access to invested capital may be restricted for an extended period, you should ensure you have sufficient liquidity elsewhere in your portfolio to meet spending needs.

Costs and manager selection

  • Private equity investments often have higher costs than public investments, so it’s important to evaluate costs and expected returns.
  • Similar to public markets, not all managers and strategies are created equal; therefore, you should be able to perform due diligence on the firm or partner with a provider who has the appropriate expertise.

Taxes

  • Depending on the investment structure, investors may receive tax documents that differ from traditional 1099 forms and may require working with a tax professional.

What allocation might be best for me, and why?

There’s no one-size-fits-all approach. Private equity allocations are individualized based on factors like your risk tolerance, cash flow needs, investment goals, and desired allocations. Vanguard’s framework and methodology suggest a private equity allocation from 0% to 40% of one’s total equity allocation, not their overall portfolio allocation.

The chart below shows hypothetical private equity allocations and the considerations that might lead an investor to decide on a particular level of exposure:

0% allocation: Not a fit because they have higher liquidity needs, shorter time horizons, or discomfort with uneven outcomes.

5%-10% allocation: An exploratory approach because they are cautious about liquidity or want exposure to potential upside without reliance on results.

10%-25% allocation: Deliberate allocation because they have long time horizons or acceptance of irregular cash flows.

25% or more allocation: A significant allocation because they are comfortable having money tied up, strong manager access, and portfolios built to absorb outcomes that can vary widely.

Which allocation best represents your situation?

An advisor can help determine whether to invest and how much to allocate to ensure alignment with your goals, time horizon, liquidity needs, and portfolio risk to improve outcomes. Schedule time today.

With private equity ("PE") investments, there are five primary risk considerations: market, asset liquidity, funding liquidity, valuation, and selection. Certain risks are believed to be compensated risks in the form of higher long-term expected returns, with the possible exceptions being valuation risk and selection risk. For selection risk, excess returns would be the potential compensation, however, limited partners ("LPs") must perform robust diligence to identify and gain access to managers with the skill to outperform. PE investments are speculative in nature and may lose value.

Market risk: Private equity, as a form of equity capital, shares similar economic exposures as public equities. As such, investments in each can be expected to earn the equity risk premium, or compensation for assuming the nondiversifiable portion of equity risk. However, unlike public equity, private equity's sensitivity to public markets is likely greatest during the late stages of the fund's life because the level of equity markets around the time of portfolio company exits can negatively affect PE realizations. Though PE managers have the flexibility to potentially time portfolio company exits to complete transactions in more favorable market environments, there's still the risk of capital loss from adverse financial conditions.

Asset liquidity risk: Various attributes can influence a security's liquidity; specifically, the ability to buy and sell a security in a timely manner and at a fair price. Transaction costs, complexity, and the number of willing buyers and sellers are only a few examples of the factors that can affect liquidity. In the case of private equity, while secondary markets for PE fund interests exist and have matured, liquidity remains extremely limited and highly correlated with business conditions. LPs hoping to dispose of their fund interests early—especially during periods of market stress—are likely to do so at a discount.

Funding liquidity risk: The uncertainty of PE fund cash flows and the contractual obligation LPs have to meet their respective capital commitments—regardless of the market environment—make funding risk (also known as commitment risk) a key risk LPs must manage appropriately. LPs must be diligent about maintaining ample liquidity in other areas of the portfolio, or external sources, to meet capital calls upon request from the General Partners ("GPs").

Valuation risk: Relative to public equity, where company share prices are published throughout the day and are determined by market transactions, private equity NAVs are reported quarterly, or less frequently, and reflect GP and/or third-party valuation provider estimates of portfolio fair value. Though the private equity industry has improved its practices for estimating the current value of portfolio holdings, reported NAVs likely differ from what would be the current "market price," if holdings were transacted.

Selection risk: Whether making direct investments in private companies, PE funds, or outsourcing PE fund selection and portfolio construction to a third party, investors assume selection risk. This is because private equity doesn't have an investable index, or rather a passive implementation option for investors to select as a means to gain broad private equity exposure. While there are measures an investor can take to limit risk, such as broad diversification and robust manager diligence, this idiosyncratic risk can't be removed entirely or separated from other systematic drivers of return. Thus, in the absence of a passive alternative and significant performance dispersion, consistent access to top managers is essential for PE program success.

All investing is subject to risk, including the possible loss of the money you invest. Be aware that fluctuations in the financial markets and other factors may cause declines in the value of your account. There is no guarantee that any particular asset allocation or mix of funds will meet your investment objectives or provide you with a given level of income.

Private investments involve a high degree of risk, and therefore, should be undertaken only by prospective investors capable of evaluating and bearing the risks such an investment represents. Investors in private equity generally must meet certain minimum financial qualifications that may make it unsuitable for specific market participants.

Private equity is generally only accessible to ultra-high-net-worth investors, either through direct investment or partnership with a private equity firm, which invests in a private equity fund. Only accredited investors who meet specific qualifications outlined in federal securities laws qualify to invest in private equity funds. Certain private equity funds require investors to meet the definition of 'qualified purchaser’ in addition to being an accredited investor.
