Published calculation methodology

equal_weight_chain_linked_close_v1: the documented STN families use equal-weight, chain-linked closing index levels. The first accepted publication starts each family at 1,000 index points.

For each published family, the daily chain factor is the arithmetic mean of constituent current-close / prior accepted close ratios. The new level is the prior published level multiplied by that factor. A baseline observation with no prior accepted closes has a factor of one.

Source validation, dates, attribution and file integrity belong to the publication evidence. A company identity correction, follow, advertisement, affiliate offer or commercial claim does not select a constituent or change its weight. The public projection does not read unpublished rebalance or restricted decision stores.

1 documented family is in this page’s scope. Source-specific missing prices or unavailable history do not establish zero performance.
