Intertek Group 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.

Intertek Group's Cyclically Adjusted Revenue per Share for the fiscal year that ended in Dec25 is calculated as:

For example, Intertek Group's adjusted Revenue per Share data for the fiscal year that ended in Dec25 was:

Adj_RevenuePerShare=Revenue per Share/CPI of Dec25 (Change)*Current CPI (Dec25)
=25.203/139.9000*139.9000
=25.203

Current CPI (Dec25) = 139.9000.
