Summary
- The post describes how a brilliant fund manager (Leopold) turned $150M into $25B in 18 months but then blew up due to excessive leverage, margin calls, and a momentum drawdown, with Citadel as the counterparty.
- The author’s thesis is that even the best stock picker can be destroyed by poor risk management and overconfidence; the lesson is that margin and leverage are dangerous, especially when success leads to psychological delirium.
Quality assessment: Speculation / anecdotal analysis. The author provides no specific data or tickers, only a narrative about a known fund blow-up. It serves as a cautionary tale rather than a research-based DD.
