    Is the 60/40 Portfolio Broken? AI, Hedge Funds & the Future of Investing | Dr. Philip Seager (Part 2)

    Is the traditional 60/40 portfolio still fit for purpose? What should investors look for in a systematic fund manager? And how is AI changing the careers of people working in finance? In Part 2 of The Most Important Thing, Alan O’Sullivan continues his conversation with Dr. Philip Seager, Head of Portfolio Strategy at Capital Fund Management (CFM). Beginning with the 2008 financial crisis, Philip explains why trend-following strategies stood out during a prolonged market downturn and how investors might think about allocations to genuinely diversifying strategies. They discuss the changing correlation between stocks and bonds, inflationary regimes, the limits of private equity as a diversifier, and why a manager’s investment process may be more revealing than a recent performance chart. The discussion then turns to CFM’s scientific research culture and the profound impact of artificial intelligence on quantitative finance. Philip describes how AI-assisted coding and prompt-based research are transforming daily workflows, while stressing the continuing importance of domain expertise, critical thinking and statistical judgement. To close, they explore the influence of physics on financial research, recommended reading, the wisdom of crowds and how market flows shape prices. Topics include managed futures, the 2008 crisis, portfolio construction, manager selection, inflation, stocks and bonds, AI in finance, scientific research and behavioural markets.

    Can AI Beat Fund Managers? Quant Investing, Market Luck & Crisis Protection | Dr. Philip Seager (Part 1)

    Can artificial intelligence outperform traditional fund managers? And how much of successful investing is genuine skill rather than market luck? In Part 1 of The Most Important Thing, Alan O’Sullivan speaks with Dr. Philip Seager, Head of Portfolio Strategy at Capital Fund Management (CFM), about the science behind quantitative investing and what it means for constructing more resilient portfolios. Drawing on his background in experimental particle physics and more than 25 years at CFM, Philip explains how systematic investors use large datasets, statistical testing and increasingly AI to identify investment opportunities. He also explores why impressive backtests can be misleading, how market beta can be mistaken for manager skill, and why traditional diversification may fail investors when they need it most. The conversation examines trend following as a potential source of genuine diversification, including its behaviour during prolonged equity drawdowns, the limitations exposed by rapid market reversals, and the difference between trend following and buying downside insurance. Topics include quantitative versus discretionary investing, alternative data, AI and neural networks, overfitting, active management, the 60/40 portfolio, trend following and crisis alpha.

    Will AI Replace White-Collar Jobs? The Future of Growth | Robert Gordon — Part 2

    Will artificial intelligence transform economic growth—or are expectations running far ahead of reality? And what does the rise of AI mean for graduates, white-collar professionals and the future of work? In Part 2 of his conversation with Dr Alan O’Sullivan, renowned economist and Northwestern University professor Robert J. Gordon challenges predictions of limitless AI-driven growth. He explains why many human-centred and physical jobs remain difficult to automate, while roles involving computer-based tasks could face significant disruption. The discussion also examines the economics behind the AI investment boom: who will ultimately generate the revenue needed to justify enormous spending on data centres, chips and electricity? Professor Gordon considers the implications for productivity, education and independent thinking, drawing on his experience teaching university students. Turning to the longer-term outlook, Gordon identifies population ageing and declining fertility as central challenges to economic growth. He discusses retirement ages, immigration, inequality and why the labour market may increasingly favour skilled trades over traditional graduate careers. They close with a recommendation of Brad DeLong’s Slouching Towards Utopia and Gordon’s advice to young people planning a career in an AI-driven economy. Topics discussedAI, automation and the future of white-collar employmentProductivity, technological progress and the return on AI investmentUniversity education, examinations and AI-generated courseworkDemographics, fertility, retirement and long-term economic growthImmigration, income inequality and skilled-trades shortagesCareer advice and book recommendationsFurther viewingRobert Gordon TED Talk — The death of innovation, the end of growth  https://www.youtube.com/watch?v=PYHd7rpOTe8&pp=0gcJCR0AztywvtLA Subscribe to The MOST Important Thing for conversations on economics, investing, wealth and the forces shaping our future.

    Gold, Commodities & the Coming Monetary Reset | Alan O’Sullivan and Ivan Yates

    Is gold the ultimate portfolio insurance — or has its extraordinary rise made it too risky? And could a changing global monetary order reshape how we invest? In this episode of The MOST Important Thing, Dr Alan O’Sullivan and Ivan Yates examine gold’s role in a diversified portfolio, the central-bank buying driving demand and the question of trust in the US dollar. They also discuss silver, copper, uranium, oil and other real assets, before weighing the opportunities and risks of Bitcoin.

    Robert Gordon: Why the Great Era of Economic Growth May Be Over | Part 1

    Professor Robert J. Gordon, one of the world’s leading economists on productivity and long-run economic growth, joins Alan O’Sullivan to examine why the extraordinary gains of the past two centuries may be becoming harder to repeat. In Part 1, Gordon explains the difference between economic growth and productivity, traces the three major industrial revolutions, and discusses why the period from 1920 to 1970 delivered such exceptional productivity growth. He also revisits the central thesis of The Rise and Fall of American Growth and explains why productivity growth has slowed since the mid-2000s. The conversation then turns to the major headwinds facing advanced economies: ageing populations, rising public debt, inequality and the diminishing contribution of education to productivity. Gordon also discusses the contrast between mature economies and faster-growing developing countries, as well as the role of energy, electrification and technology in future growth. Topics include: • Economic growth vs productivity • The three industrial revolutions • Why 1920–1970 was an exceptional period for productivity • The post-2005 productivity slowdown • Demographics and ageing populations • Government debt and interest rates • Inequality and living standards • Education and graduate underemployment • Growth in China, India and the developing world • Energy, electrification and the transition away from fossil fuels Part 2 continues the discussion with artificial intelligence, white-collar employment, education, demographics, retirement, immigration and advice for young people entering the labour market.

    The Long & Short Ep. 2 | Debt, Demographics & Sustainability

    In Episode 2 of The Long & Short, Ivan Yates and Dr. Alan O'Sullivan examine three of the major forces shaping economies, markets and long-term investment decisions: debt, demographics and sustainability. The discussion moves from the global sustainability challenge and the renewed debate around nuclear energy to rising government debt and the consequences of increasingly heavy debt burdens.

They then turn to demographics and pensions, including falling worker-to-retiree ratios, longer life expectancy and the pressure these trends place on state pension systems. The episode also looks at private credit and shadow banking, liquidity and underwriting risks, Ireland's deemed disposal rules, and the role of state savings and government bonds in a portfolio. Topics include: • Debt, deficits and diminishing economic returns • US government debt and the Treasury market • Climate, energy security and nuclear power • Ageing populations and pension sustainability • Private credit and shadow banking risks • Deemed disposal and long-term investing in Ireland • State savings, government bonds and inflation Featured clips from previous episodes: • Justin Huhn – Part 1: Is Uranium the Most Important Investment Story of the Next Decade? • Justin Huhn – Part 2: Uranium’s Long Runway: China, Scarcity & the Nuclear Investment Opportunity • Mike Bell, CFA – Part 1: How to Gain an Edge in Markets: History, Cycles & Bubbles • Mike Bell, CFA – Part 2: Gaining an Edge in Financial Markets • Dr. Lacy Hunt – The Debt Crisis Nobody Wants to Talk About • Prof. Brian O'Kelly – Banking Risk, Debt & the Future of Finance The Long & Short is part of The Most Important Thing, with Ivan Yates and Dr. Alan O'Sullivan, looking beyond the headlines at the forces driving markets, economies and investment portfolios.
