On this page we presented the WLK Historical PE Ratio information for Westlake' stock. The average WLK historical PE based on using the annualized quarterly earnings result at each measurement period (for the "E" in the PE calculation; and the closing price on earnings date as the "P") is 17.1. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average WLK historical PE based on this TTM earnings result method is 14.5.

Let's now compare this WLK historical PE result, against the recent PE: when this page was posted on 4/17/2024, the most recent closing price for WLK had been 148.59, and the most recent quarterly earnings result, annualized, was 2.88. Meanwhile, the most recent TTM earnings summed to 8.28. From these numbers, we calculate the recent WLK PE on 4/17/2024 based on annualized quarterly EPS was 51.6. Based on WLK's history, that recent PE is elevated relative to the historical average, with the recent PE 201.8% higher than the historical average PE across our data set for Westlake. Looking at the recent WLK PE on 4/17/2024 based on TTM EPS, we calculate the ratio at 17.9. Based on WLK's history, that recent PE is elevated relative to the historical average, with the recent PE 23.4% higher than the historical average PE across our Westlake data set with TTM EPS used in the calculation at each period.

Another interesting WLK historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for WLK, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for WLK, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.72, 2.20, 2.31, and 3.05. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 2.20 and 2.31 — which gives us the median of 2.25. Basically the way to think about this 2.25 number is this: for the trailing four earnings reports, 2.25 marks the "middle ground" number where WLK has reported a value higher than 2.25 half the time, and has reported a value lower than 2.25 half the time. Annualizing that median value then gets us to 9/share, which we use as the denominator in our next PE calculation. With 148.59 as the numerator (as of 4/17/2024), the calculation is then 148.59 / 9 = 16.5 as the WLK PE ratio as of 4/17/2024, based on that annualized median value we calculated.
