Low multiples such as earnings multiples or book multiples generally represent good values. While this may not be always true, it is true enough that they make for a great screen to shortlist stocks for further review. In this screen we go after the traditional trifecta of low price/book, low price/earnings and low price/sales. At the same time, we are look for some history of sales and earnings growth.
This gives us a good shortlist of stocks from which we can further narrow down our focus by quick review of other fundamental data.
