Stock-Bond Return Dynamics and the Expected Country Stock Returns
研究发现，当国家特定风险上升时，股票和债券价格会同步变动，此时股票投资回报比两者负相关时每年高出7%至11%，对跨国投资者有参考价值。
Stock and bond prices of a country move together with increasing country-specific risk. Bonds effectively hedge growth expectation risk when country-specific risk is low, resulting in a negative stock-bond correlation. However, as country-specific risk increases, hedging is less effective because (1) rising domestic prices tend to reduce a country’s growth potential and (2) global growth expectation shocks are more persistent than country-specific ones. Consequently, countries with greater country-specific risk exhibit a relatively positive stock-bond correlation. Equity investments in these countries outperform those with negative relationships by 7%–11% annually. The superior performance is not driven by investing in a fixed set of countries.
