摘要

我们的研究首次考察了美国贸易政策不确定性(TPU)对中国股票的定价影响。我们估计了美国TPU贝塔,它衡量的是中国股票对美国TPU指数的敞口。投资组合分析和横截面回归都表明,美国TPU beta与预期回报之间存在显著的负相关关系,这无法用其他定价因素来解释。与TPU贝塔值最高的股票相比,美国TPU贝塔值最低的股票的年回报率可以高出3.48%。此外,我们使用向量自回归模型提供了两种潜在的机制,包括实体经济渠道和行为金融渠道。我们的研究结果表明,负溢价可以通过要求更多的高TPU贝塔股票来对冲TPU的不利影响,以及由于噪音交易者的悲观信念而卖出更多的低TPU贝塔股票来解释。

U.S. Trade Policy Uncertainty and Expected Stock Returns of Chinese Listed Companies
Our study is the first to examine the pricing effect of U.S. trade policy uncertainty (TPU) on Chinese stocks. We estimate the U.S. TPU beta, which measures Chinese stock exposure to the U.S. TPU index. Both portfolio analyses and cross-sectional regressions suggest a significantly negative relation between the U.S. TPU beta and expected returns, which cannot be explained by other pricing factors. The stocks in the lowest U.S. TPU beta quintile can generate 3.48% higher annual returns compared to stocks in the highest U.S. TPU beta quintile. Furthermore, we provide two potential mechanisms that include a real economy channel and a behavioral finance channel using vector autoregression models. Our results indicate that the negative premium can be explained by both demanding more of high TPU beta stocks in hedging against adverse effects from TPU and selling more of low TPU beta stocks due to pessimistic beliefs of noise trader.
