The article discusses the advantages and challenges of private equity co-investment for limited partners. While co-investments promise lower fees and more control over portfolio construction, direct co-investments have actually underperformed private equity funds over the past decade. Sourcing good co-investment deals is difficult for most LPs, as the best opportunities are often restricted to large deals syndicated by top-tier GPs. Even for giant LPs, achieving co-investment targets can be a challenge given the resources required to put capital to work through smaller deals. Overall, while attractive in theory, co-investing does not guarantee better returns or control in practice for many investors.
