Capacity, Benchmark Choice, and Diversification in Quantitative Funds
Summary
This report reviews the relative performance of Chinese quantitative equity funds and considers what rising assets under management mean for strategy design. It attributes the period’s advantage for index-enhanced and quantitative long products largely to opportunities in small- and mid-cap stocks, which outperformed large-cap benchmarks. It also reports changing correlations between some quantitative strategy indices and market or commodity momentum benchmarks, alongside drawdowns in excess returns when trading activity fell and style factors reversed.
The report argues that growing assets can make returns more dependent on broad market exposures, liquidity, and prevailing styles, while limiting capacity. It recommends assessing the stability of managers’ excess returns, considering benchmarks beyond broad indices, and developing allocations across strategies to reduce dependence on any single approach. It also highlights lower-crowding, valuation-supported index enhancement and long-short equity as areas to examine. The cited performance figures describe a particular period and sample; the report flags representativeness, survivorship bias, team changes, capacity constraints, and policy shocks as risks.
Key ideas
- Small- and mid-cap market structure helped quantitative index-enhancement funds outperform during the period discussed.
- Fund growth can increase capacity pressure and make strategy returns more correlated with market exposures.
- Excess returns may weaken when trading volume and liquidity decline or market styles reverse.
- Managers can reduce style dependence by improving benchmarks and allocating across strategies.
- Historical product samples may be affected by survivorship bias, team changes, capacity limits, and policy shocks.
