原文是:For tax reasons, the stock price may go down by somewhat less than the cash amount of the dividend.
然后赫尔又举了一个例子:if a dividend of $1 per share is anticipated and the share price normally goes down by 80% of the dividend on the ex-dividend date。
我不理解的地方是:为什么税收会对除息后股票下跌的数量有影响呢?这里所说的税收是指对分派现金股息所征收的税吗?
