The Price to Earnings Ratio (also known as PER and P/E Ratio) is calculated as the price of a share divided by the Earnings per Share (aka EPS). The price to earnings ratio is the inverse of earnings yield.

For example, suppose that company XYZ has a market price of 210 cents per share, and earnings per share of 15 cents per share, the PER would be:
	    = 210   / 15
	    = 14
A lower PER is better, cet. par.
