❓ Why It Matters
Ignoring cycles repeats the same mistakes: excessive optimism at peaks and excessive pessimism near troughs. Context matters for position sizing.

Treating short rebounds as full cycle turns
Extrapolating peak conditions indefinitely
Becoming maximally defensive near valuation troughs
📚 Case Studies
1
Ray Dalio’s European Debt Crisis Hedges (2011)
As Europe’s sovereign debt crisis escalated, Bridgewater Associates, led by Ray Dalio, reportedly used macro hedges like options on bonds, currencies, and equity indexes to guard against tail risks such as euro fragmentation, banking stress, and deflationary shocks that could ripple globally.
✨ Outcome：Bridgewater navigated the period with relatively strong performance versus many peers. The case underlined the value of systematic, options-based macro hedging to cushion portfolios during unpredictable, low-probability macro events.

Ackman’s Public Short of Herbalife (2012)
In December 2012, Bill Ackman’s Pershing Square disclosed a $1 billion short position in Herbalife, presenting a detailed, public, multi-hour thesis claiming it was a pyramid scheme. Ackman released research, slide decks, and media appearances explaining his rationale and maintained regular public updates as the highly controversial battle with the company and rival investors unfolded.
✨ Outcome：The short ultimately lost money as Herbalife settled with regulators but survived. The episode showed that radical transparency can build a following and trust in process, even when the investment is wrong.
