The authors study time-variation in the co-movements between daily stock and Treasury bond returns over 1986 to 2000. Their innovation is to examine whether variation in stock-bond return dynamics can be linked to non-return-based measures of stock market uncertainty, specifically the implied...

We study whether asset-class risk dynamics can help explain the predominantly negative stock-bond return relation and movements in the term-structure's slope over 1997-2011. Using option-derived implied volatilities to measure risk, we find: (1) the negative stock-bond return relation largely...

We show that equity volatility serves as a determinant of future Treasury term-structure volatility over the recent October 1997 to June 2013 period. We find that equity volatility contains incrementally reliable information for the subsequent volatility of: (1) 10-year and 30-year bond futures...

We show there is a much stronger negative dynamic relation between changes in economic uncertainty and Treasury yields over weaker-economic times since at least 1990. We document this economic-state variation in uncertainty-yield dynamics for weekly and monthly change horizons, for nominal...
