Consider a financial year and suppose that the highest and lowest closing prices for a stock are $74.68 and $44.09. This data will be displayed in the Scenario Analysis and the company charts.
Suppose that the earnings per share (eps) for this year is $3.27.
Then high PE ratio is calculated as 74.68 / 3.27 = 22.84 and the low PE ratio is calculated as 44.09 / 3.27 = 13.48. The numbers 22.84 and 3.27 are displayed in the Scenario Analysis and the company charts.
The Scenario Analysis also displays what is referred to as the current high and low PE ratios. These are calculated by dividing the highest and lowest closing prices over the most recent 12 months by the earnings per share over the same period (EPSttm: earnings per share trailing 12 months).
Suppose the highest and lowest prices over the most recent 12 months are $74.68 and $49.71. Suppose also that EPSttm is $3.44. Then the current high PE ratio is 74.68 / 3.44 = 21.71 and the current low PE ratio is 49.71 / 3.44 = 14.45.
