Hudson Bay seeks research opportunities with academia, through which we can share our unique portfolio construction philosophy.

Hudson Bay has co-authored a series of white papers with Dr. Harry Markowitz, winner of the Nobel Memorial Prize in Economic Sciences, in connection with his pioneering work in Modern Portfolio Theory. This collaboration reflects our belief that Hudson Bay’s investment process is an enhanced application of Dr. Markowitz’s framework in a multi-asset, multi-strategy alpha portfolio hedge fund environment.

No, Stocks Aren’t in a Valuation Bubble — Not Even Close

Jason Cuttler

One common refrain in markets and media is that “stocks are expensive” with some even calling today’s market a speculative bubble. While we agree that the P/E multiple is elevated relative to history, we don’t see high P/E as a binding constraint against valuation expanding further. Rather, AI-related technological progress and resulting broadbased productivity gains could lead to renewed market optimism and a commensurate “sentiment premium” in the market, along the lines of the 1985-2001 period. Such optimism, combined with current levels of interest rates, could justify an S&P 500 level of $9,000 (+34% relative to S&P trading at $6,7001) or more over time. Investors who myopically focus instead on the recent history of P/E multiples risk missing out on such generational upside. Moreover, the options market prices a mere ~8% probability of the S&P reaching that lofty level in the next two years. We think the true probability is much higher. At Hudson Bay, we invest holistically, question the experts, and remain aware of macro trends. With this paper, and its companion published by Hudson Bay Senior Economic Strategist Nouriel Roubini, we invite readers to join us in this approach.

Tech Trumps Tariffs: US Exceptionalism and the AI Productivity Boom

Dr. Nouriel Roubini

While the consensus market outlook since the April 2nd “Liberation Day” tariff shock has been pessimistic about the US economic outlook, this pessimism ignores how market discipline, institutional guardrails, and the scale of AI-led investment — spanning advanced semiconductors, automation, and the data-center build-out — are likely to outweigh any stagflationary drag.
