$YANKUANG ENERGY(01171.HK) Tomorrow is the ex-dividend date, and today's trend has the flavor of buying in anticipation of the dividend, pushing up the stock price. The closing price minus the dividend of HKD 0.5886 is the corresponding ex-dividend price. Considering the 20% dividend tax for Stock Connect investors and the 10% dividend tax for Hong Kong investors, for those holding positions at today's close, Stock Connect investors need the stock to rise by HKD 0.12 and Hong Kong investors by HKD 0.06 tomorrow to offset the tax impact. Long-term investors need not worry about the ex-dividend date, but short-term investors should know that buying stocks before the ex-dividend date to capture dividends is irrational.
