Determinants of equity returns on ex-dividend dates in emerging capital markets
We study share price performance at ex-dividend date, and its relation to trading volume and a set of factors corresponding to different explanatory theories. Among the investigated factors that may have impact on ex-dividend date share price, are dividend yield, capital gains tax rate and dividends tax rate, transaction costs, market microstructure characteristics, market stock risk, and disposition effect. The research was conducted with the panel data of companies from BRIC zone for the period 2005-2015. According to obtained results, dividend capturing and disposition effect theories are likely to have explanatory power for ex-day phenomenon for our sample. Tax theory and dividend clientele theory have not found empirical support.
