We propose a tractable framework for quantifying the impact of fire sales on the volatility and correlations of asset returns in a multi-asset setting. Our results enable to quantify the impact of fire sales on the covariance structure of asset returns and provide a quantitative explanation for...

We decompose volatility of a stock market index both in time and scale using wavelet filters and design a probabilistic indicator for valatilities, analogous to the Richter scale in geophysics. The peak-over-threshold method is used to fit the generalized Pareto probability distribution for the...

Stock market indices are today a vital and daily tool for both economists and actors in the financial world. The multiplication and the very importance given to these indices raise the question of their accuracy and of the reliability of the methods that are used to construct them. We begin an...
