On this page we presented the Quest Diagnostics Historical PE Ratio information for Quest Diagnostics' stock. The average DGX 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 15.0. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average DGX historical PE based on this TTM earnings result method is 15.0.

Let's now compare this DGX historical PE result, against the recent PE: when this page was posted on 4/10/2024, the most recent closing price for DGX had been 131.62, and the most recent quarterly earnings result, annualized, was 8.6. Meanwhile, the most recent TTM earnings summed to 8.71. From these numbers, we calculate the recent DGX PE on 4/10/2024 based on annualized quarterly EPS was 15.3. Based on DGX's history, that recent PE is elevated relative to the historical average, with the recent PE 2.0% higher than the historical average PE across our data set for Quest Diagnostics. Looking at the recent DGX PE on 4/10/2024 based on TTM EPS, we calculate the ratio at 15.1. Based on DGX's history, that recent PE is elevated relative to the historical average, with the recent PE 0.7% higher than the historical average PE across our Quest Diagnostics data set with TTM EPS used in the calculation at each period.

Another interesting DGX historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for DGX, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for DGX, we start with the past four EPS numbers and we first sort them from lowest to highest: 2.04, 2.15, 2.22, and 2.30. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 2.15 and 2.22 — which gives us the median of 2.19. Basically the way to think about this 2.19 number is this: for the trailing four earnings reports, 2.19 marks the "middle ground" number where DGX has reported a value higher than 2.19 half the time, and has reported a value lower than 2.19 half the time. Annualizing that median value then gets us to 8.76/share, which we use as the denominator in our next PE calculation. With 131.62 as the numerator (as of 4/10/2024), the calculation is then 131.62 / 8.76 = 15.0 as the DGX PE ratio as of 4/10/2024, based on that annualized median value we calculated.
