How should the IBM 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 IBM. 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 IBM Historical PE Ratio page.
What is the average historical PE for IBM 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 IBM historical PE ratio using the annualized quarterly earnings method works out to 12.8.
What is the average historical PE for IBM 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 IBM historical PE ratio using the TTM earnings method works out to 11.5.
What is the average historical PE for IBM 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 IBM historical PE ratio using the annualized median TTM earnings method works out to 8.
On this page we presented the IBM Historical PE Ratio
information for IBM' stock.
The average IBM 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 12.8. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average IBM historical PE based on this TTM earnings result method is 11.5.
Let's now compare this IBM historical PE result, against the recent PE: when this page was posted on 9/25/2023, the most recent closing price for IBM had been 146.48, and the most recent quarterly earnings result, annualized, was 8.72. Meanwhile, the most recent TTM earnings summed to 8.95. From these numbers, we calculate the recent IBM PE on 9/25/2023 based on annualized quarterly EPS was 16.8. Based on IBM's history, that recent PE is elevated relative to the historical average, with the recent PE 31.2% higher than the historical average PE across our data set for IBM. Looking at the recent IBM PE on 9/25/2023 based on TTM EPS, we calculate the ratio at 16.4. Based on IBM's history, that recent PE is elevated relative to the historical average, with the recent PE 42.6% higher than the historical average PE across our IBM data set with TTM EPS used in the calculation at each period.
Another interesting IBM historical PE Ratio calculation we look at is to take the median
earnings per share of the last four quarters for IBM, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for IBM, we start with the past four EPS numbers and we first sort them from lowest to highest: 1.36, 1.81, 2.18, and 3.60. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 1.81 and 2.18 — which gives us the median of 2.00. Basically the way to think about this 2.00 number is this: for the trailing four earnings reports, 2.00 marks the "middle ground" number where IBM has reported a value higher
than 2.00 half the time, and has reported a value lower
than 2.00 half the time. Annualizing that median value then gets us to 8/share, which we use as the denominator in our next PE calculation. With 146.48 as the numerator (as of 9/25/2023), the calculation is then 146.48 / 8 = 18.3
as the IBM PE ratio as of 9/25/2023, based on that annualized median value we calculated.
For self directed investors doing their due diligence on IBM or any other given stock, valuation analysis for IBM
can greatly benefit from studying the past earnings and resulting PE calculations. This exercise can help inform an analysis
as to whether the past earnings trajectory and current versus historical PE ratios justify the current stock value.
