Estimation of the interdependence of time series of stocks prices based on copula



The relationships in the stock markets, the impact on them of the structural changes in the economy, the ability to adequately forecast for a certain period are investigated. The analysis of the interdependence of stock prices by using copula functions is carried out. The statistical estimations of copulas on a lattice with a step 0.1 are constructed. The distances in the metric L1 from the empirical copula to the maximum (comonotonic), minimum (countermonotonic) and independent copulas are compared
