The MOST Important Thing

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 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.

In this episode of The Long & Short, Ivan Yates and Dr Alan O’Sullivan revisit the Wall Street Crash of 1929, the 2008 global financial crisis and today’s concerns around AI valuations, defence stocks and changing investment regimes. From speculative bubbles to excessive private debt, they explore why crashes happen, what investors can learn from previous cycles, and whether the old investment playbook still works.
Featuring insights from previous conversations with financial historian Edward Chancellor, economist Professor Steve Keen and investor Jesse Felder, alongside an additional perspective from financial historian Professor Russell Napier.
Topics covered: historical bubbles and market psychology; the role of private debt in 2008; falling interest rates and the shift towards real assets; bull and bear markets; AI and dot-com comparisons; contrarian positioning; economic cycles; and lessons from Ireland’s financial history.

Are Bonds a Buy?
This episode explores whether bonds are becoming attractive again amid sticky inflation, rising fiscal concerns, and the AI spending boom. Alan argues that bond markets are pricing in deeper risks, but the best opportunity to buy may come after a significant sell-off in US stocks.
Key topics
Why Treasury yields have fallen despite hotter-than-expected inflation
How public debt, fiscal deficits, and bond-market volatility may affect equities
Why corporate bond yields could be an early warning for stocks
How falling real yields could make gold more attractive
Europe’s weak growth outlook and pressure on the euro
Inflation, interest rates, and the resilient US economy
Why Alan’s verdict on bonds is “not yet”—and what he’s watching next

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 discussed
AI, automation and the future of white-collar employment
Productivity, technological progress and the return on AI investment
University education, examinations and AI-generated coursework
Demographics, fertility, retirement and long-term economic growth
Immigration, income inequality and skilled-trades shortages
Career advice and book recommendations
