Rebalance
The scheduled moment when a list’s membership is allowed to change — the Top 10 is rebalanced on the first trading day of each month. Scores move every night; membership only moves on the calendar.
Scores are recomputed nightly and shown nightly, but the ten names are only reconsidered on a fixed schedule: the lists are rebalanced on the first trading day of each month. Separating the two is deliberate. A list whose membership chased the score every night would change constantly for reasons no reader could follow, and the record of what was chosen and when — which is the point of publishing a list in the open — would dissolve into noise. Between rebalances the scores on the page are current and the membership is as of the last rebalance, and both dates are shown.
At a rebalance three things can happen to the ten. A member whose rank has held stays. A member whose rank has fallen past the keep threshold leaves. Each slot that opens is filled by the highest-ranked company that is not already a member and does not breach the sector limit, which is at most 4 of the 10 from any one sector on the market-wide list. Every one of those outcomes — including a company that was skipped because its sector was already full — is written to an append-only ledger with the pillar that moved most and the figures behind it, so "why did this leave" always has an answer rather than an inference.
One kind of change does not wait for the calendar. A company that stops being eligible at all — delisted, or with a pillar that can no longer be computed — leaves immediately, with that recorded as the reason rather than as a rank drop, because the two are different facts and reporting the first as the second would be untrue. A sector list exists only where a sector has at least 25 eligible companies to rank, and once open it stays open while that count holds at 20 or better; below that it closes and the page says so, naming the count, rather than publishing a ten padded out of a field too small to rank meaningfully.
