The effect of adding private equity to a portfolio depends - as always - on the portfolio itself. However, a Pantheon study from 2015* suggests that adding 20% private equity to an equity portfolio can unlock 3.16% of annualized excess return. Viewed over an investment horizon of 10 to 20 years, this has a significant impact on wealth accumulation.
Reasons for this include:
Access to unlisted companies
The number of companies available for investment in public markets is limited and each traded company is carefully screened. Although public markets can never be truly "efficient," the value of a company going public will likely already be recognized, causing the price to skyrocket at that point. Private equity funds have access to the private market, and thus to a larger pool of unknown opportunities that are not subject to rigorous vetting. They have the resources to viscerally vet these companies and figure out which ones are worthy of investment.
Leverage
Private equity investments are often financed with debt. This practice allows the fund to deploy a smaller amount of cash while simultaneously magnifying profits in the event of a sale. Of course, the opposite is also true: if the investment fails, there is a significant risk of loss.
Value Creation
Since the goal of private equity investing is to sell the stake in the company, there is a strong motivation to create value. Most modern private equity firms have clear value creation methodologies and often dedicated value creation teams within the firm. Value creation initiatives can include restructuring, cost reduction, technology improvements, or the introduction of ESG frameworks, all of which are thoroughly planned before an investment is made.
