Segment HHI

Segment spread: concentration of revenue across reported segments

One of the 61 measures in Stock Scorer, under Durability — How predictable is the revenue, and how much of it is already committed?

How it is worked out

Sum of each reported segment's squared share of revenue (Herfindahl index)

A concentration measure: one segment gives 1.0, five equal segments 0.2. Low means revenue is spread out. It counts the segments a filer chooses to report, so a miner reporting sixteen mines still sells one commodity.

How to read it

one segment earns a 1, five equal ones a 10. The nearest thing filings offer to customer concentration — but it counts the segments a filer chooses to report, and a miner reporting sixteen mines still sells one commodity

Which figures it needs

Computed from 1 figure taken from the filing:

• revenue

The XBRL tags behind it

These are the element names looked for in a filing, in order. The first one a company reports is the one used, and the company page names which it was — so any figure here can be checked against the filing it came from.

• Revenues
• RevenueFromContractWithCustomerIncludingAssessedTax

Whether it counts

This measure is not counted by default. It can be added to Durability on the dashboard, and it then takes its share of that dimension.
