Publication Open Access Spillover dynamics effects between risk-neutral equity and treasury volatilities(Springer, 2022) González Urteaga, Ana; Nieto, Belén; Rubio, Gonzalo; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaMacro-finance asset pricing models provide a rationale for connectedness dynamics between equity and Treasury risk-neutral volatilities. In this paper, we study the total and directional connectedness, in the sense of spillover effects, between risk-neutral volatilities from the equity and Treasury markets. In addition, we analyze the economic and monetary drivers of connectedness dynamics. Most of the time, but especially during bad economic times, we find significant net spillovers from Treasury to equity risk-neutral volatility. The spillover channel between risk-neutral volatilities arises mainly through the government fixed income market.Publication Open Access Extracting expected stock risk premia from option prices and the information contained in non-parametric-out-of-sample stochastic discount factors(Routledge, 2020) González Urteaga, Ana; Nieto, Belén; Rubio Irigoyen, Gonzalo; Enpresen Kudeaketa; Institute for Advanced Research in Business and Economics - INARBE; Gestión de Empresas; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaThis paper analyzes the factor structure and cross-sectional variability of a set of expected excess returns extracted from option prices and a non-parametric and out-of-sample stochastic discount factor. We argue that the existing potential segmentation between the equity and option markets makes it advisable to avoid using only option prices to extract expected equity risk premia. This set of expected risk premia significantly forecasts future realized returns, and the first two principal components explain 94.1% of the variability of expected returns. A multi-factor model with the market, quality, funding illiquidity, the default premium and the market-wide variance risk premium as factors significantly explains the cross-sectional variability of expected excess returns. The (asymptotically) different from zero adjusted cross-sectional R-squared statistic is 83.6%.Publication Open Access A forecasting analysis of risk‐neutral equity and Treasury volatilities(Wiley, 2019) González Urteaga, Ana; Nieto, Belén; Rubio Irigoyen, Gonzalo; Gestión de Empresas; Enpresen Kudeaketa; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaThis paper employs equity (VIX) and Treasury (MOVE) risk‐neutral volatilities to assess their relative forecasting performance with respect to future real activity, stock and Treasury excess returns, and aggregate risk factors. The in‐sample evidence suggests that the square of VIX tends to dominate the square of MOVE. Out‐of‐sample predictive analysis, performed as a horse race between equity and Treasury risk‐neutral volatilities, shows that, contrary to earlier results, the square of VIX and MOVE tend to complement each other.
