Josh Duitz, head of global income at Abrdn -- manager of the Aberdeen Global Infrastructure Income Fund -- says that private infrastructure investments have attracted so much money that valuations have gotten off-kilter, creating an 'illiquidity premium' that 'makes no sense.' Duitz explains that publicly listed companies should have higher valuations -- because investors value the liquidity and ability to trade them easily -- meaning that current conditions are making public infrastructure investments particularly attractive right now. Duitz -- who says that politics isn't likely to impact infrastructure as much as headlines suggest -- makes a broad case for infrastructure investing now, but particularly likes the renewable space.
