Eric Purington, portfolio manager and infrastructure specialist at abrdn, says that middle-market private investments are a path to profitability and outperformance now due to a supply-demand imbalance that has large-cap operators -- working with an 'ocean of capital' looking to do more acquisitions and pay a premium for them. Purington, who is responsible for private-market investments for the abrdn Global Infrastructure Income Fund, says that while infrastructure provides services and assets for the community and predictable cash flows for investors, the premiums being paid for middle-market assets could generate roughly '200 basis points of outsized returns' moving forward.
