The event led to over \$10 billion in losses across multiple major banks. *** ### Market Context Archegos built large positions in a small group of equities, including: * ViacomCBS * Discovery * Baidu * Tencent Music These positions were established using **total return swaps**, allowing Archegos to gain exposure without directly owning the shares.
*** ### The Core Mechanism The strategy relied on: * concentrated bets on a few stocks * significant leverage through derivatives * continued price stability or upward movement Because of the structure, actual exposure was much larger than visible capital. *** ### What Changed Several of the core positions began to decline: * negative price movement triggered losses * margin requirements increased * counterparties demanded additional collateral As positions moved against Archegos, pressure intensified rapidly. *** ### Why It Failed #### 1. Extreme Concentration The portfolio was heavily concentrated in a small number of equities. → losses were not diversified *** #### 2. Correlated Exposure Many positions were driven by similar market dynamics. → multiple assets declined simultaneously *** #### 3. High Leverage Use of swaps allowed Archegos to take positions far larger than its capital base. → small price changes had amplified effects *** #### 4. Lack of Transparency Positions were spread across multiple prime brokers. → no single counterparty had full visibility of total exposure *** ### Outcome As prices declined: * margin calls increased * positions were liquidated * forced selling accelerated the decline This created a feedback loop: → falling prices → forced selling → further price declines The portfolio collapsed within days. *** ### Key Insight > Leverage and concentration can transform moderate market moves into systemic failures. *** ### Structural Lesson The failure was not caused by a single trade. It resulted from: * excessive leverage * concentrated positions * correlated exposure * lack of risk visibility *** ### Connection to Risk Management This case illustrates that: * apparent diversification can be misleading * leverage amplifies both gains and losses * correlation increases under stress * hidden exposure can accumulate across positions *** ### Final Insight The relevant question is not: > “How large is each position?” But: > “How large is total exposure under stress?” *** ### Related Concepts → *Accounting for Correlated Risk in Trading*\ → *Blowing an Account with 5% Risk*\ → *Kelly vs Fixed Risk*
