How should the DGX historical PE ratio be determined?
Realizing that PE stands for Price to Earnings ratio, we need two values to compute it: stock price and earnings per share. The stock price at any given date is a known historical value, but what about the earnings number to use?
There are a number of different approaches when it comes to calculating a historical PE ratio for a company like Quest Diagnostics. We like to take our measurements on each of the past quarterly earnings reports. That only leaves the question of whether the earnings number at that quarterly report should be used on an annualized basis, or some other method. We approach this question using three different methods, on this DGX Historical PE Ratio page.
What is the average historical PE for DGX based on annualized quarterly earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use that quarter's earnings result annualized?
The DGX historical PE ratio using the annualized quarterly earnings method works out to 14.9.
What is the average historical PE for DGX based on trailing twelve month earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use the trailing twelve months combined earnings result in the calculation?
The DGX historical PE ratio using the TTM earnings method works out to 15.2.
What is the average historical PE for DGX based on median TTM earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use the median earnings over the trailing twelve months and annualize that median result in the calculation?
The DGX historical PE ratio using the annualized median TTM earnings method works out to 13.12.
On this page we presented the DGX 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 14.9. 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 15.2.
Let's now compare this DGX historical PE result, against the recent PE: when this page was posted on 6/17/2022, the most recent closing price for DGX had been 130.64, and the most recent quarterly earnings result, annualized, was 12.88. Meanwhile, the most recent TTM earnings summed to 13.69. From these numbers, we calculate the recent DGX PE on 6/17/2022 based on annualized quarterly EPS was 10.1. Based on DGX's history, that recent PE is low relative to the historical average, with the recent PE 32.2% lower than the historical average PE across our data set for Quest Diagnostics. Looking at the recent DGX PE on 6/17/2022 based on TTM EPS, we calculate the ratio at 9.5. Based on DGX's history, that recent PE is low relative to the historical average, with the recent PE 37.5% lower than the 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: 3.18, 3.22, 3.33, and 3.96. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 3.22 and 3.33 — which gives us the median of 3.28. Basically the way to think about this 3.28 number is this: for the trailing four earnings reports, 3.28 marks the "middle ground" number where DGX has reported a value higher
than 3.28 half the time, and has reported a value lower
than 3.28 half the time. Annualizing that median value then gets us to 13.12/share, which we use as the denominator in our next PE calculation. With 130.64 as the numerator (as of 6/17/2022), the calculation is then 130.64 / 13.12 = 10.0
as the DGX PE ratio as of 6/17/2022, based on that annualized median value we calculated.
