This is a question that often arises when someone is looking at the following Simply Wall St infographs:
- PEG Ratio
- Past and future EPS
- Analyst growth expectations
- Profit history
Our PEG ratio is calculated based on the most recent PE Ratio and updated EPS Growth Rate based on consensus analysts forecast. Other sites may show different PEG ratios as they might be using out of date EPS growth rates or figures that are based on historical data. Our PEG ratio is more up to date than others as it changes as the market price moves, when there are revisions on consensus analysts estimates or if there is a new earnings report which could affect PEG calculations.
For EPS, Revenue and Profit we use quarterly results but based on an annual period to enable comparisons between periods and bring analysis more up to date as compared to using end-of-year data or company's annual results. This is known as the Trailing Twelve Month (TTM) also called as the Last Twelve Month (LTM) data.
A way to think about it is like this:
In Q4 2016, Apple reported quarterly revenue of $78.351B
(source: Yahoo Finance)^
But on Simply Wall St, the figures are far larger.
That figure ($218.118B) is the combined value of the quarterly Revenues from the last 12 months. So it would include the most recent figure of $78.351B + the other three previous quarterly revenues.
While the Profit ($45.215B), as shown below, is the combined value of the quarterly Net Income from the last 12 months. So it would include the most recent figure of $17.891B + the other three previous quarterly revenues.
