Weather influence on speculation on stock markets
 Horáček, Jan ; Pánková, Václava (advisor) ; Křepelová, Marika (referee)
Topic of this master thesis is to examine whether weather related mood changes are in correlation with price of stocks. Thesis focuses on middle Europe stock market indexes PX, SAX, ATX and DAX. Research is based on relationship between daily cloud cover and development of the indexes form 1995 to 2012. It also focuses on comparison of several different models, especially models of seemingly unrelated regressions. It shows that indexes PX and ATX are significantly negatively correlated with local cloud cover. Use of seemingly unrelated regressions offers slightly better results. The relation between cloud cover and stock indexes is not strong enough to be used for weather based speculations
