This episode explores the severe market volatility and hedge fund losses of October and early November, driven by crowded trades and the unwinding of the artificial intelligence narrative. Hosts Tracy Alloway and Joe Weisenthal speak with Bloomberg News hedge fund correspondent Nishant Kumar and macro strategist Michael Ball about how major multi-strategy funds like Millennium, Balyasny, and Point 72 suffered historic declines simultaneously. The discussion details how intense leverage, correlated positioning in AI stocks, and mechanical factors like negative gamma and volatility control selling created a cascading market washout.

- Multi-strats employ ruthless risk management systems that cut capital allocations or fire portfolio managers after specific percentage losses. 21:22

About this episode
Even before the US midterms, the AI trade was weakening. Just look at all the headlines from October in the hedge fund world https://www.bloomberg.com/news/articles/2026-11-06/crowded-hedge-fund-trades-are-unwinding-fast-after-ugly-october — it was one of the bloodiest periods the industry has faced in recent memory. Now, after the blue wave, things continue to look uncertain. So what's going to happen with the AI buildout now? And what about the big Anthropic IPO? Today's episode is a two-parter, one that examines both the hedge fund carnage of the last few weeks and the broader macro conditions we find ourselves in after the midterm elections. We speak with two of our Bloomberg News colleagues — Nishant Kumar, chief correspondent for hedge funds, and macro strategist Michael Ball — and they help lay out why October was a historic month for hedge funds and what they are paying attention to now as jitters from the AI trade continue to work their way through the market.
