Determinace cen akcií komoditních společností cenami produkovaných komodit

The thesis deals with the relationship between the stock prices of commodity companies and commodity prices produced by these companies. Each commo-dity was testing with three related companies. In this thesis was used various methods for testing. Namely Engle-Granger test of cointegration, the correlation analysis, Granger causality test and VAR-GARCH model for testing volatility spilloves between markets. Empirical results show that effect of commodity to shares is different for each group of commodities. The most evident effect appears at the impact of industrial and precious metals on mining companies and the effect of oil prices on the shares of the oil companies. In contrast, the prices of gas and agricultural commodities did not influence the prices of those commodities shares significantly
