P-E RATIO: Also termed the price-earnings ratio, this is the ratio of the current price for one share of corporate stock to the earnings (profit) per share of stock. This is used by many financial analysts and investors as an indicator of a company's performance and potential for future growth.

CONCENTRATION RATIOS

A family of measures of the proportion of total output in an industry that is produced by a given number of the largest firms in the industry. The two most common concentration ratios are for the four largest firms and the eight largest firms. The four-firm concentration ratio is the proportion of total output produced by the four largest firms in the industry and the eight-firm concentration ratio is proportion of total output produced by the eight largest firms in the industry. Concentration ratios are commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control of the largest firms in the industry. A related measure is the Herfindahl index.
