Ruentex Interior Design Peter Lynch Fair Value Calculation

Ruentex Interior Design's Peter Lynch Fair Value for today is calculated as

Peter Lynch Fair Value=PEG Ratio*5-Year TTM EBITDA Growth Rate***EPS without NRI (TTM)
=1* 12 *19.39
=232.68

Ruentex Interior Design's EPS without NRI for the trailing twelve months (TTM) uses the latest annual data, which was NT$19.39.

* Note that for companies that do not have enough quarterly data to calculate the 5-Year TTM EBITDA Growth Rate, we use the annual data for the calculation.


* For Operating Data section: All numbers are indicated by the unit behind each term and all currency related amount are in USD.
* For other sections: All numbers are in millions except for per share data, ratio, and percentage. All currency related amount are indicated in the company's associated stock exchange currency.

** 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.
