In 2005, Harry Markopolos, a portfolio manager at Rampart Investment Management, sent a 21-page report to the SEC's New York office explaining why Bernard Madoff was running "the world's largest Ponzi scheme." He had modeled Madoff's split-strike conversion strategy and found no realistic source of consistently high returns. He had managed a similar strategy himself and could not reproduce the smooth, predictable performance Madoff claimed cycle after cycle. The SEC did not act.
Problems driven by market losses. When a fund collapses during market stress, the collapse usually combines external pressure with internal flaws that predate the stress, like a poorly built structure failing in a storm.
Amaranth Advisors (2006). Amaranth was a self-described multi-strategy hedge fund, but by 2006 it had devoted roughly half its capital to natural gas, generating about 75% of profits. Star trader Brian Hunter, based in Calgary far from the Greenwich head office, established long winter delivery contracts and short nonwinter contracts.
Long-Term Capital Management (1998). LTCM, founded in 1994 by Salomon Brothers executives with two Nobel laureates on its board, pursued relative value (fixed-income arbitrage) trades expecting spreads between similar securities...
Common mistakes
- Treating red flags individually instead of as clusters. One isolated flag with a satisfactory explanation rarely disqualifies a manager. A cluster (manipulated-return signatures plus related-party auditor plus non-independent administrator plus refused transparency) is the fraud signature. Trap: choosing "decline" on a single recent auditor change when the correct answer is "investigate further."
- Letting the CIO also serve as CRO. Risk management must function independently from investment management. Trap: a scenario where the chief investment officer "also oversees risk" should be flagged as a control failure, not accepted as efficient.
- Confusing a qualified custodian with a prime broker. A custodian holds assets for the fund's benefit; a prime broker provides financing and execution and creates counterparty risk. Trap: treating "prime broker at a name-brand bank" as evidence of safe custody.
Bottom line
- Market-loss collapses (Amaranth, LTCM, Carlyle Capital, XIV) each paired external market stress with a distinct internal flaw.
- The leverage-return identity is ; confirmation bias and anchoring push managers toward leverage and concentration as opportunities shrink.
- Large-loss probability is nonlinear in leverage: a 3:1 fund's odds of a given equity loss rise far faster than .
- Trading-technology failures are the Quant Meltdown (unwind hypothesis), the Flash Crash (spoofing, circuit breakers), and Knight Capital ($460M).
Exam shortcut
Before scoring any DD scenario, count red flags. One isolated flag with a credible explanation means investigate and proceed with monitoring. Two or more clustered flags, or any resistance to standard DD, means decline. Refused third-party custody, a related-party or self-audit, and a non-independent administrator are automatic declines regardless of reputation, because each directly enables fraud concealment.
