RDC Semiconductor Co  (ROCO:3228) Cyclically Adjusted PS Ratio Explanation

Compared with the regular PS Ratio, which works poorly for cyclical businesses, the Cyclically Adjusted PS Ratio smoothed out the fluctuations of revenue during business cycles. Therefore it is more accurate in reflecting the valuation of the company.

If a company has consistent business performance, the Cyclically Adjusted PS Ratio should give similar results to regular PS Ratio.

RDC Semiconductor Co 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.

RDC Semiconductor Co's Cyclically Adjusted Revenue per Share for the quarter that ended in Mar. 2026 is calculated as:

For example, RDC Semiconductor Co's adjusted Revenue per Share data for the three months ended in Mar. 2026 was:

Adj_RevenuePerShare=Revenue per Share/CPI of Mar. 2026 (Change)*Current CPI (Mar. 2026)
=1.059/330.2130*330.2130
=1.059

Current CPI (Mar. 2026) = 330.2130.
