“…Yang, Zhou, and Wang (2009), by using a large time span that covers 150 years of data at a monthly frequency, recognize that higher stock–bond correlations tend to follow higher short rates or higher inflation rates. Aslanidis and Christiansen (2014) find that macroeconomic fundamentals are the most useful explanatory variables when the stock–bond correlation is largely negative, while Dimic et al (2016) argue that the most important factor influencing stock–bond correlation in the short‐term is the monetary policy; whereas in the long‐term, inflation and stock market uncertainty are the major drivers. Christopher, Kim, and Wu (2012) stress the importance of sovereign credit ratings on time‐varying stock and bond market correlations, while Chiang et al (2015) find evidence that stock–bond correlations are negatively correlated with stock market uncertainty, as measured by the conditional variance and the implied volatility of the S&P 500 index, but positively related to bond market uncertainty.…”
