We stress the importance of distinguishing between realized volatility and … implied volatility, and find that implied volatilities are essential for assessing the volatility feedback effect. The … leverage hypothesis asserts that return shocks lead to changes in conditional volatility, while the volatility feedback effect …

We propose a jump robust positive semidefinite rank-based estimator for the daily covariance matrix based on high-frequency intraday returns. It disentangles covariance estimation into variance and correlation components. This allows to estimate correlations over lower sampling frequencies, to...

The theory of cost of capital (long-term) assets [Sharpe, 1964, Lintner, 1965, Mossin, 1966] based on G. Markovits's model [Markovitz, 1952,1059], for many years forms base for estimated calculations in the investment analysis and corporate finance. But it implicitly means an assumption that the...
