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.

Harmonic's Cyclically Adjusted PB Ratio for today is calculated as

Cyclically Adjusted PB Ratio=Share Price/ Cyclically Adjusted Book per Share
