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.

Aeroports de Paris Business Description

Address 1 rue de France, Tremblay en France, Paris, FRA, 93290
Aeroports de Paris owns and operates Paris' commercial airports, Charles de Gaulle, Orly, and Paris-Le Bourget, and has equity holdings in TAV Airports and GMR Airports. The Parisian airports operate under a hybrid-till regime, but there is no cross-subsidy, which leaves their commercial businesses largely unregulated. The Parisian business is split between regulated aviation activities, retail and services businesses, and real estate activities. In 2025, retail and services contributed 56% of the group's operating profit, despite generating only 32% of the group's sales. It has a relatively high contribution from its international segment among our European airport coverage, with 28% of group EBITDA deriving from overseas operations in 2025.
