Institutional Investors, Heterogeneous Benchmarks and the Comovement of Asset Prices

Thursday, April 19, 2018

Andrea Buffa, Assistant Professor of Finance, Boston University

We study the equilibrium implications of a multi-asset economy in which asset managers are each subject to a different benchmark. We demonstrate how heterogeneous benchmarking endogenously generates a mechanism through which fundamental shocks propagate across assets. Asset managers' capital invested for benchmarking purposes enters the pricing kernel and fluctuations in this capital induce price pressure that can result in negative spillovers across asset returns. We study the equilibrium properties of benchmarking-induced negative spillovers by analyzing shock elasticities and cross-elasticities of price-dividend ratios and asset managers' market shares. Our results, which are obtained in closed-form, are also in line with the weakened correlation across industry-sector portfolios and investment styles over short horizons, and provide new testable implications on the established asset-class" effect. An asset that is included in a benchmark may not only comove negatively with assets included in a different benchmark, but also with assets belonging to the same benchmark.
