Topic: Conditional Expected Returns on Individual Stockswith and without Intertemporal Hedging

Speaker: Assistant professor Gang Li (李罡 助理教授)

The Chinese University of Hong Kong (CUHK)

Abstract: We derive tractable lower and upper bounds on the conditional expected excess return of an individual stock in a dynamic multi-period economy with portfolio rebalancing. The bounds depend on higher-order risk-neutral joint moments of market and stock returns and are implementable ex ante using index and single-name option prices. Our framework nests a no-intertemporal-hedging benchmark, isolating and quantifying the role of hedging motives. Empirically, the bounds are economically tight and outperform leading one-period benchmarks in out-of-sample forecasts of stock returns. The significant gap between hedging and non-hedging bounds highlights the role of intertemporal hedging in expected returns on individual stocks.
