W.E.T. New England Football Index 6mo

new-england-football-inside-six-months-inverse reads 61.37 against this index’s 38.63. Same markets, opposite side.

7 input(s) were quarantined by sentinel/v1 before this close and are excluded from the reading above.

• The board stops listing markets that name New England's football clubs inside this window: the selector then admits fewer than 6 markets and the index prints nothing rather than a level over a roster that no longer states the thesis.
• Weight coverage falls below the declared floor of 95%, at which point the published state is insufficient_data and no value is printed — never a value carried forward from the last close that had one.
• A New England club in another sport starts sharing this one's published vocabulary, at which point the declared exclusions stop separating the two and the composition would silently become an all-sports index for this metro wearing a single-sport name.

The governed close level above is divisor-chained: it tracks how the desk’s reading of this perspective has moved since 2026-08-14, and it survives a roster change because the divisor absorbs it. It is not a basket total return.

The basket total return below is a position book: it holds a fixed set of contracts from its own inception and reports what that book did, marks and settlements included. A roster change starts a new book rather than being absorbed.

They share a base of 1,000 and nothing else. Expect them to differ, and read the one that answers your question — the chained level for “where does this perspective stand”, the book for “what would holding it have done”.
