[求助]关于financial services companies与price multiple

NOTES上有一句话：

A screen to identify firms with low P/E ratios will likely exclude growth companies from the sample.意思是说growth companies 一般都会有较大的P/E ratios吗？

下一句：A low P/B or high dividend screen will likely include an inordinate proportion of financial services companies. 想问的是，在这句话中金融服务业公司的特征是？这句话的意思是？

谢谢！
