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 PS Ratio. The Cyclically Adjusted Revenue per Share is the average of the inflation adjusted revenue per share of a company over the past 10 years.
Precision Optics's adjusted revenue per share data for the three months ended in Mar. 2026 was $1.117. Add all the adjusted revenue per share for the past 10 years together and divide 10 will get our Cyclically Adjusted Revenue per Share, which is $2.85 for the trailing ten years ended in Mar. 2026.
