The conversation also covers AI’s shift toward capital-intensive business models, GPU depreciation, intangible assets, and the importance of testing investment ideas rather than chasing impressive backtests. Topics covered: Why Rob Arnott sees a real AI revolution alongside risks in the prices of its leading stocks How AI customers could capture value beyond the infrastructure builders Valuation changes versus fundamental growth in large and smaller companies Tesla, SpaceX, and the price pressures surrounding index inclusion Hidden implementation costs that do not appear in an index fund’s expense ratio Selecting index members by business size rather than market value AI financing, customer economics, and the risk of rapid hardware obsolescence R&D, intangible assets, and what conventional book value can miss Competitive moats, leadership, and creating value for customers Using AI in research while resisting overfitting and performance chasing Research discussed: ⁠The Active Side of Indexing⁠ ⁠Fundamental Growth⁠ Learn more about ⁠Syzygy Asset Management⁠.

How can investors participate in powerful growth trends without making every holding a bet on the same outcome?

Colin McQueen of T. Rowe Price explains what is changing for international value stocks and how he separates cheap businesses from opportunities that can improve. Higher interest rates, industrial investment, and corporate reform are reshaping the opportunity set, but his process still starts with free cash flow and the price investors pay for it. Colin joins Justin Carbonneau and Jack Forehand to discuss his evolution from deep value investing to a broader approach that includes quality businesses and restructuring opportunities. We explore why value struggled in the 2010s, what has changed outside the US, and how he uses valuation signals and diversification to manage risk. The conversation also covers AI suppliers and disruption, governance changes in Japan and Korea, opportunities and risks in China, and the case for financial stocks. Colin shares examples involving Samsung, Hitachi, and Rolls-Royce, along with his experiments using AI to challenge investment theses and recognize when conviction has become stubbornness. Topics covered: The lessons Colin McQueen learned from deep value, quality investing, and a difficult decade for value How higher rates and spending on infrastructure, defense, and power can change the opportunity set AI supply-chain opportunities and the uncertainty around future winners and losers Valuing tangible and intangible businesses through normalized free cash flow Using AI as an alternative voice when deciding whether an investment thesis is broken The US-international valuation gap, earnings growth, and diversification beyond tech Japan's corporate reforms, Korea's value-up effort, and the importance of what is already priced in China's contrarian appeal and the governance risks that accompany it How restructuring, management changes, and better capital allocation can unlock value Building a diversified portfolio and looking beyond quarterly earnings and market narratives

Jim Paulsen sees a risk of a stock market correction as financial conditions tighten and investors grow comfortable with tech's long run of leadership. But his warning does not require a recession or the end of the bull market. In this month's Jim Paulsen Show, Jim joins Justin Carbonneau and Jack Forehand to walk through the charts behind his cautious outlook. He explains how rising yields, oil prices, and a firmer dollar can affect the economy with a lag, why favorable seasonality may offer less support than investors expect, and how a slowdown in technology spending could challenge market leadership. We also explore the signals Jim sees in retail, housing, employment, and Walmart's relative performance. He closes with a possible path through a correction: slowing growth, lower inflation and yields, and a recovery that could give the bull market another run. His seven lagging sectors, the "Modest Seven," are central to that case. Topics covered: Why Jim Paulsen is cautious without making a recession or full bear-market call His financial-conditions gauge and the risks of tightening into an already pressured economy How restrictive conditions can weaken the November-to-April seasonal advantage The delayed effects of bond yields, oil prices, and the dollar on economic surprises Technology spending relative to GDP and why slower growth could matter for tech stocks AI adoption, pricing, and the challenge of turning investment into profits How two decades of tech leadership may encourage complacency and crowded positioning The divide between AI, inflation-assisted sectors, and the "Modest Seven" What sector performance, bond yields, and the Walmart Recession Signal suggest about growth Why rate cuts may initially accompany falling stocks, and how a correction could set up another advance Follow Jim Paulsen: Paulsen Perspectives Jim Paulsen on X Timestamps: 00:00 Jim Paulsen's outlook: correction risk without a bear-market call 07:41 Restrictive conditions and the seasonal buying period 14:12 Why the Fed and investors interpret conditions differently 20:28 Oil, yields, the dollar, and their lagged effects 26:00 Technology spending relative to the economy 30:18 Can AI break the historical pattern? 35:00 Tech's long leadership cycle and investor complacency 42:00 AI, inflation-assisted sectors, and the Modest Seven 47:06 Market signals ahead of economic reports and bond pressure 53:00 Bond competition and the Walmart Recession Signal 58:11 How a correction could lead to another bull-market run Learn more about the Excess Returns podcast network: https://excessreturns.co No information discussed in this podcast should be construed as investment advice.
