最近股票跌了，分红不变，所以才显得很多

现在7.5%是因为2016年底股票跌了很多。

再看2015年的新闻：

High-yield energy stocks are everywhere. One of the best is Royal Dutch Shell plc(NYSE:RDS-A) (NYSE:RDS-B), a European oil major with a 5.5% dividend yield. Shell's dividend yield is unusually high right now because its share price has fallen approximately 25% over the past six months.
