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 release 3.16% of the annualised excess return. Looking at an investment horizon of 10 to 20 years, this has a significant impact on wealth accumulation. The reasons for this include the following:
Access to unlisted companies
The number of companies available for investment on public markets is limited and each traded company is carefully scrutinised. Although public markets can never be truly "efficient", by the time a company goes public, its value will likely already be recognised, causing the price to skyrocket at that point. Private equity funds have access to the private market and therefore to a larger pool of unknown opportunities that are not subject to rigorous scrutiny. They have the resources to scrutinise these companies and identify which ones are suitable for investment.
Leverage effect
Private equity investments are often financed with debt. This practice allows the fund to deploy a smaller amount of cash, while at the same time allowing profits to be magnified 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-enhancing measures
Since the goal of private equity investments 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 organisation. Value creation initiatives can include reorganisations, cost reductions, technological improvements or the introduction of ESG frameworks, all of which are thoroughly planned before an investment is made.
