A company's price/earnings (P/E) ratio can be calculated by dividing the current market price of a share by the earnings per share (EPS). A high P/E ratio means the company is highly-rated by the stock market, suggesting that investors think its prospects are good.
More extensive explanations of these terms are provided by a number of books in our collection, including The Financial Times Guide to Investing and The Financial Times Guide to using the Financial Pages.
The Financial Times publishes P/E ratios for companies and industry sectors in its 'Companies and Markets' section.
The FT Data Archive (subscription required) provides scans of the relevant tables for the last five years. Select the date you need and the reports London Share Service, World Markets at a Glance or FT 500.
The Library & Information Service also holds the FT on microfilm from 1975 to the end of 2016.
The Risk Measurement Service is a quarterly publication from London Business School. It provides data on the yield and earnings multiple (including the net yield and P/E ratio) for 3,000 UK shares, including every UK stock with a full listing on the London Stock Exchange and all AIM listed stocks. The listings of companies are arranged alphabetically and by sector, with tables for the highest and lowest P/E ratios.
The Library & Information Service holds the Risk Measurement Service from 2008 onwards.
