In Episode 12 of Markets and Mindsets, the team are joined by Rich, a former international athlete and professional trader with two decades of experience across market-making, hedge funds and emerging markets. Rich reflects on the physical and psychological toll of trading through major market events, including the financial crisis, the Swiss franc de-pegging and periods of extreme volatility. The conversation explores the difference between short, sharp bursts of adrenaline and the longer-lasting build-up of cortisol, and how both can influence decision-making, focus, sleep and behaviour. The team also discusses when stress can improve performance, why routine and a documented process can reduce pressure, and the practical warning signs that trading may be taking over your life. From diet, exercise and sleep to position sizing, time away from the screen and stress-testing your portfolio, the episode examines how traders can protect their health while continuing to engage with the markets they love.
