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 PB Ratio. The Cyclically Adjusted Book per Share is the average of the inflation adjusted book value per share of a company over the past 10 years.

ShineMore Technology Materials Co's adjusted book value per share data for the three months ended in Mar. 2026 was NT$3.739. Add all the adjusted book value per share for the past 10 years together and divide the count will get our Cyclically Adjusted Book per Share, which is NT$21.77 for the trailing ten years ended in Mar. 2026.

ShineMore Technology Materials Co Cyclically Adjusted PB Ratio Calculation

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

ShineMore Technology Materials Co's Cyclically Adjusted PB Ratio for today is calculated as

Cyclically Adjusted PB Ratio=Share Price/ Cyclically Adjusted Book per Share
=34.00/21.77
=1.56

* 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.

ShineMore Technology Materials Co's Cyclically Adjusted Book per Share for the quarter that ended in Mar. 2026 is calculated as:

For example, ShineMore Technology Materials Co's adjusted Book Value per Share data for the three months ended in Mar. 2026 was:

Adj_Book=Book Value per Share/CPI of Mar. 2026 (Change)*Current CPI (Mar. 2026)
=3.739/330.2130*330.2130
=3.739

Current CPI (Mar. 2026) = 330.2130.
