Excess Returns

This episode explores one of the most important debates in markets today: whether investors are underestimating the risk of higher inflation and overconcentrating in a narrow group of growth stocks.
Richard Bernstein of Janus Henderson Investors joins Excess Returns to explain why today’s environment may look more like the inflationary 1960s than the 1970s, what that means for portfolios, and why many investors may be disappointed with passive index returns over the next decade.
Richard walks through the implications of rising import prices, global conflict, and deglobalization, and how these forces could drive a structural shift toward higher inflation and shorter-duration investing. He also explains why market concentration, AI enthusiasm, and capital flows may be setting up a broadening opportunity across overlooked areas of the market.

This episode features David Rosenberg, founder of Rosenberg Research, breaking down why today’s market may be driven more by valuation excess and investor behavior than fundamentals. He explains why the biggest risks right now are not obvious in headline data, and why the probability distribution for markets may be far more fragile than investors assume.
Rosenberg walks through his framework for thinking in probabilities, how AI-driven productivity is distorting economic signals, why the equity market is now driving the economy, and what a “silent contraction” beneath the surface could mean for growth, inflation, and returns. He also outlines how he is positioning portfolios in response to these risks.
