Digesting FOREXS: Information Transmission Across Asset Classes and Return Predictability
研究发现股权投资者对货币冲击反应滞后，通过构建外汇操作相关冲击指标，预测企业未来现金流和股票回报，基于此策略年化超额收益达6.74%。
We provide novel evidence that equity investors react to currency shocks with a delay. Using the cross-section of currency returns and the relative presence of U.S. firms in foreign economies, we compute a foreign operations-related exchange shock (FOREXS) measure. We find FOREXS to predict firms’ future cash flows and stock returns, driving much of the previously documented underreaction to foreign information. An FOREXS-based long-short strategy yields a 6.74% annualized abnormal return. FOREXS predictive power comes from firms’ incomplete hedging and investors’ limited attention, highlighting the challenges involved when processing information from a different asset class.
