Within the sector

Rank 3 of 9 in the industry. Median of total points in this industry: 13.0 of 20, across 9 graded companies. The grades are absolute and are not normalised to the sector: in a weak industry a weak grade stays weak.

The neighbours follow from the ranking alone, not from a judgement. More total points does not mean a company is the better investment, only that more quality rules are met. It says nothing about the price.

How durable the advantage is

free to read

4 of 10 points, measured over 10 years (2016 to 2025). Classification: weak.

FeaturePointsBasis
Return on capital, level1/3The company earns on average 8.4% of its assets per year as operating profit, measured over 10 years. Comparable companies are around 10%.
Return on capital, consistency0/31 of 10 years above 10%. Consistency is the real evidence, because anyone has one good year.
Pricing power1/2Gross margin averaging 25%, trending +5.2 percentage points from the first third to the last. A margin that holds for a decade is pricing power. One that melts away is competition.
Stability in a downturn2/2Operating margin averaging 19%. Tested in 2020 and 2022: 2020 21%, 2022 20%. Holding counts from two thirds of the company's own average.

What is measured is the trace of a moat: a durably high return on capital and margins that survive a downturn. The causes (switching costs, network effects, brand, licences, economies of scale) appear in no filing and are not claimed here.
