📚 Case Studies
1
Pershing Square’s COVID-19 Hedge Disclosure (2020)
In early 2020, Ackman publicly described Pershing Square’s massive credit hedges against COVID-19–related market turmoil, later fully detailing the structure, timing, and rationale in letters and interviews. After markets crashed and the hedges paid off, he explained how he redeployed profits into portfolio companies, openly discussing both the fear his comments caused and the fund’s decision-making.
✨ Outcome：Pershing Square earned billions on the hedge, then strong returns on redeployed capital. Transparent post‑mortems on a profitable but controversial trade reinforced credibility and investor trust.
2
Warren Buffett’s Dempster Mill Disaster (1962)
Buffett bought Dempster Mill, a windmill manufacturer, very cheaply, assuming mean reversion in earnings. Operations kept deteriorating; management was weak and the industry structurally challenged. The investment stagnated for years and consumed attention and capital before Buffett brought in new management and eventually liquidated/sold assets.
✨ Outcome：Buffett concluded that buying mediocre businesses just because they’re cheap is dangerous. He shifted toward “wonderful businesses at fair prices,” paving the way for Berkshire’s focus on quality franchises like See’s Candies and Coca‑Cola.
