The Shiller PE Ratio was first used by professor Robert Shiller. He uses E10 for his Shiller PE Ratio calculation. E10 is the average of the inflation adjusted earnings per share of a company over the past 10 years. The similar calculation is applied by GuruFocus to calculate the Cyclically Adjusted PS Ratio. The Cyclically Adjusted Revenue per Share is the average of the inflation adjusted revenue per share of a company over the past 10 years.

M31 Technology's adjusted revenue per share data for the three months ended in Jun. 2026 was NT$9.244. Add all the adjusted revenue per share for the past 10 years together and divide 10 will get our Cyclically Adjusted Revenue per Share, which is NT$33.36 for the trailing ten years ended in Jun. 2026.

M31 Technology Cyclically Adjusted PS Ratio Calculation

Like the Shiller PE Ratio, the Cyclically Adjusted PS Ratio takes the Revenue per Share from the past 10 years, adjusts it for inflation, and then calculates the average. This average is then used for the P/S calculation. Because it considers this 10-year average, it's often referred to as the CAPS Ratio.

The Shiller PE Ratio was first used by professor Robert Shiller to measure the valuation of the overall market. The similar calculation is applied by GuruFocus to calculate the Cyclically Adjusted PS Ratio.

M31 Technology's Cyclically Adjusted PS Ratio for today is calculated as

Cyclically Adjusted PS Ratio=Share Price/ Cyclically Adjusted Revenue per Share
=409.50/33.36
=12.28

* 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.

M31 Technology's Cyclically Adjusted Revenue per Share for the quarter that ended in Jun. 2026 is calculated as:

For example, M31 Technology's adjusted Revenue per Share data for the three months ended in Jun. 2026 was:

Adj_RevenuePerShare=Revenue per Share/CPI of Jun. 2026 (Change)*Current CPI (Jun. 2026)
=9.244/333.9520*333.9520
=9.244

Current CPI (Jun. 2026) = 333.9520.
