Telecomunicacoes Brasileiras 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.

Telecomunicacoes Brasileiras's Cyclically Adjusted Book per Share for the quarter that ended in Mar. 2026 is calculated as:

For example, Telecomunicacoes Brasileiras'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)
=16.303/175.0655*175.0655
=16.303

Current CPI (Mar. 2026) = 175.0655.
