The Forward PE Ratio of a company is often used to compare current earnings to estimated future earnings, as well as gaining a clearer picture of what earnings will look like without charges and other accounting adjustments. If earnings are expected to grow in the future, the Forward PE Ratio will be lower than the current PE Ratio. This measure is also used to compare one company to another with a forward-looking focus.
Trailing PE Ratio relies on what is already done. It uses the current share price and divides by the total EPS (Basic) over the past 12 months. PE Ratio can be affected by Non Operating Income such as the sale of part of businesses. This may increase for the current year or quarter dramatically. But it cannot be repeated over and over. Therefore PE Ratio without NRI is a more accurate indication of valuation than PE Ratio .
