Jack In The Box (MEX:JACK) Peter Lynch Fair Value Explanation
Peter Lynch Fair Value applies to growing companies. The ideal range for the growth rate is between 10 - 20% a year.
Peter Lynch thinks that the fair P/E value for a growth company equals its growth rate, that is PEG = 1. The earnings here is trailing twelve month (TTM) earnings. For non-bank companies, the growth rate we use is the average growth rate for EBITDA per share over the past 5 years. For Banks, the growth rate we use is the average growth rate for Book Value per share over the past 5 years.
Please don't confuse Peter Lynch Fair Value with the value reached in Peter Lynch Chart. In Peter Lynch chart, a fixed P/E ratio of 15 is used to draw the Earnings Line. Therefore the value reached has a P/E ratio of 15.

** Please be aware that the 5-Year TTM EBITDA Growth Rate is calculated based on TTM data over the last 5 years. For quarterly reported companies, the TTM data adds up the quarterly data reported by the company within the most recent 12 months. For companies that report semi-annually, annually, or do not have enough quarterly data, GuruFocus uses the annual data as the TTM data.
If 5-Year Earnings Growth Rate is greater than 25% a year, we use 25.
If 5-Year Earnings Growth Rate is smaller than 5% a year, we do not calculate Peter Lynch Fair Value.
Please note that we use the 5-year average growth rate of EBITDA per share as the growth rate for non-bank companies, as EBITDA growth is subject to less manipulations than net earnings per share. For banks, we use the 5-year average growth rate of Book Value per share as the growth rate. The reason is that EBITDA is not applicable to Banks and Book value is a relative important measurement for Banks. In the calculation, PEG=1 because Peter Lynch thinks that the fair P/E ratio of the growth stock is equal to its earnings growth rate.
