    We propose a new decomposition of the realized covariance matrix into components based on the signs of the underlying high-frequency returns. Under an asymptotic setting in which the sampling interval goes to zero, we derive the asymptotic properties of the resulting realized semicovariance measures. The first-order asymptotic results highlight how the concordant components and the mixed-sign component load differently on economic information concerning stochastic correlation and jumps. The second-order asymptotics, taking the form of a novel non-central limit theorem, further reveals the fine structure underlying the concordant semicovariances, as manifest in the form of co-drifting and dynamic ``leverage'' type effects. In line with this anatomy, we empirically document distinct dynamic dependencies in the different realized semicovariance components based on data for a large cross-section of individual stocks. We further show that the accuracy of portfolio return variance forecasts may be significantly improved by using the realized semicovariance matrices to ``look inside'' the realized covariance matrices for signs of direction

    This paper proposes a generalization of the class of realized semivariance and semicovariance measures introduced by Barndorff-Nielsen, Kinnebrock and Shephard (2010) and Bollerslev, Li, Patton and Quaedvlieg (2020a) to allow for a finer decomposition of realized (co)variances. The new "realized partial (co)variances" allow for multiple thresholds with various locations, rather than the single fixed threshold of zero used in semi (co)variances. We adopt methods from machine learning to choose the thresholds to maximize the out-ofsample forecast performance of time series models based on realized partial (co)variances. We find that in low dimensional settings it is hard, but not impossible, to improve upon the simple fixed threshold of zero. In large dimensions, however, the zero threshold embedded in realized semi covariances emerges as a robust choice.

    We establish basic facts about the external finance premium. Tens of millions of individual loan contracts extended to euro area firms allow studying the determinants of the external finance premium at the country, bank, firm, and contract levels of disaggregation. At the country level, the variance in the premium is closely linked to sovereign spreads, which are important in understanding financial amplification mechanisms. However, country level differences only explain half of the total variance. The rest is predominantly attributed to variances at the bank and firm levels, which are influenced by the respective balance sheet characteristics. Studying the response of the external finance premium to monetary policy, we find that balance sheet vulnerabilities of banks and firms strengthen the transmission of policy measures to financing conditions. Moreover, our findings reveal an asymmetrical effect contingent upon the sign and type of the policies. Specifically, policy rate hikes and quantitative easing measures exert a more pronounced impact on lending spreads, further magnified through their repercussions on the external finance premium.
