Professor Simon Gervais explains how active managers can grow the economy, even when they don’t beat the market

Many investors are told that active funds rarely outperform passive index funds after fees. So why bother paying for them?

In this episode of Duke Fuqua Insights podcast, Professor Simon Gervais, a financial economist at Duke University’s Fuqua School of Business, challenges the narrow way we evaluate active money management. Drawing on his paper, “Money Management and Real Investment”, Gervais argues that focusing only on fund returns misses a critical role active managers play in the economy: improving how capital is allocated across firms and industries. Rather than acting as passive observers, active managers influence real corporate investment decisions through the information embedded in stock prices.

The central insight of Gervais’s research is that active money managers can create economic value even if their funds generate negative net returns after fees. By trading on information about industries, competition, and macroeconomic trends, active managers help direct capital toward more productive uses. The result is a “bigger economic pie,” even if investors receive a slightly smaller slice of it.

Active managers trade on information that corporate executives may not fully have, pushing stock prices up or down. Firms then learn from these price movements and adjust investment decisions accordingly. As Gervais puts it, if a firm announces a merger and its stock went down, maybe that is the signal that the merger was a bad idea.

For MBA students and business leaders, the takeaway is a broader view of value creation. Passive investors may benefit indirectly from better capital allocation, but unlike active managers, they don’t automatically adjust as the economy changes. The research calls into question how regulators, investors, and institutions evaluate asset managers. If active management improves productivity and risk allocation, then traditional performance metrics like alpha may be incomplete. As Gervais suggests, the real challenge is learning how to measure not just who captures value, but who creates it.
