Does Derwent London have an economic moat?
Not clearly

The numbers behind it
Return on invested capital, average of recent years-1.2%
Return on invested capital, latest year3.0%
Gross margin51.8%Share of each sale left after production costs
Net margin41.4%
How we decide
A moat shows up in the numbers as high returns that last. We call it likely when the average return on invested capital over recent years is at least 15% and the gross margin at least 40%, and possible from 10%. The numbers can't show where a moat comes from (brand, network, patents), only that one seems to exist.
