We consider the problem of ex-ante forecasting conditional correlation patterns using ultra high frequency data … correlation matrices and exogenous factors. The Fisher-z transformation guarantees robustness of correlation estimators under … prominent parametric and nonparametric alternatives to correlation modeling. Based on economic performance criteria, we …

It is well known that the correlation between financial series varies over time. Here, the forecasting performance of … different time-varying correlation models is compared for cross-country correlations of weekly G5 and daily European stock … market indices. In contrast to previous studies only the correlation and not the entire covariance matrix is forecasted and …

We study whether prices of traded options contain information about future extreme market events. Our option-implied conditional expectation of market loss due to tail events, or tail loss measure, predicts future market returns, magnitude, and probability of the market crashes, beyond and above...

This paper proposes a latent dynamic factor model for low- as well as high-dimensional realized covariance matrices of stock returns. The approach is based on the matrix logarithm and allows for flexible dynamic dependence patterns by combining common latent factors driven by HAR dynamics and...

Most pricing and hedging models rely on the long run temporal stability of a sample covariance matrix. Using a large dataset of equity prices from four countries, the US, UK, Japan and Germany, we test the rolling stability of realized sample covariance matrices using two complementary...

Asset return covariances at intra-day horizons are known to be biased towards zero due to market microstructure effects. Thus, traders who simply scale their daily covariance forecast to match their trading horizon, are likely to over-estimate the actual experienced asset dependence. In this...

We propose an ex ante measure of analysts' production of private information (PPI) based on the correlations between analysts' forecast revisions and prior stock price changes. We validate this measure by examining whether analysts with lower correlations (higher PPI) provide more information...
