In 2007, Merrill Lynch, Goldman Sachs, Credit Suisse, and Morgan Stanley each moved to introduce investable hedge fund replication products. Academics had first studied replication in the early 2000s while building performance benchmarks for hedge funds. These initiatives renewed a hard question: how much of a hedge fund's return is repeatable beta you can buy cheaply, and how much is manager skill you must pay for?
An overview of replication products. Hedge fund replication products (also called clones or trackers) are built to capture the traditional and alternative betas underlying the expected return and risk of a hedge fund benchmark. Alternative betas are exposures to risk, risk premiums, and sources of return not normally available through traditional assets, or that come bundled with other risks. Examples include volatility, commodity, and currency risk, arbitrage strategies such as merger arb or convertible arb, and momentum or trend-following.
You may benefit from replication products even without allocating to them. They help you understand the underlying risks of hedge funds and build better benchmarks.
Common mistakes
- Treating replication as "hedge funds minus fees." Research confirms perfect replication is not possible. Factor-based replication tracks monthly returns reasonably (correlation near 0.80) but misses the mean, standard deviation, and higher moments. Trap answer: "replication delivers hedge fund returns minus the fee savings." Correct: it delivers an approximate, mostly systematic return profile.
- Listing SMAs or replication as access modes. The curriculum names exactly three approaches: direct, delegated (funds of hedge funds), and indexed. Separately managed accounts are a liquidity and transparency tool within the direct approach, not a fourth mode. Trap: a question offering "five access modes."
- Confusing the factor-based and payoff-distribution approaches. The factor-based approach aims to match returns. The payoff-distribution approach (Amin and Kat 2003) aims only to match the return distribution. Trap: assuming a high correlation product also matches skewness and kurtosis, or that a distribution-matching product tracks monthly returns.
Bottom line
- Replication products (clones or trackers) capture the traditional and alternative betas of a hedge fund benchmark using factor-based, algorithmic (bottom-up), or payoff-distribution approaches.
- There are exactly three approaches to accessing hedge funds: direct, delegated (funds of hedge funds), and indexed. SMAs and replication products are not separate curriculum access modes.
- The delegated (FoHF) approach provides five services: sourcing managers, due diligence, strategy and fund selection, portfolio construction, and risk management and monitoring.
- Replication products pass more gross return to investors: 83.33% versus 62.78% for hedge funds and 50.47% for funds of funds.
Exam shortcut
CAIA Level II vignettes on access will test whether you know there are exactly three approaches. If an answer choice presents SMAs or replication products as standalone "access modes" alongside direct, delegated, and indexed, it is wrong. Anchor on the curriculum's three.
