Snapshots of Not So Smart Alphas

Quickly apply original, key PMR-published papers with Snapshots—a short article companion that distills PMR research into compressed, digestible takeaways, so you can put the paper’s core ideas to work in your investment process—fast. This Snapshot article is based on research arguing that alpha estimates for active funds are highly sensitive to model choice, benchmark selection, omitted factors, and timing assumptions, so those alpha estimates should be treated as model-based, uncertain signals rather than clear proof of manager ability.
