Published daily index history
A citable, public research dataset of derived STN daily index levels. It covers the seven security-industry index families and contains market dates, changes, methodology version and source-file provenance—not raw company share prices.
This release contains 259 accepted observations from 2026-09-09 through 2026-10-29. Missing market dates are not interpolated, forward-filled or treated as zero.
Daily means accepted market-session observations, not a promise that a weekend or holiday produces a new close. A new validated publication makes new rolling downloads available; previously archived releases keep their content address.

Link to the permanent family page for context and to an archived release for reproducible data. A source correction produces a different content digest rather than rewriting a previously retained release.
Data dictionary and interpretation
Export columns: index_code, index_name, trade_date, level, change_abs, change_pct, constituent_count, methodology_version, published_at, source_file_sha256, source_attribution, source_terms_url, canonical_url. Unavailable daily changes are blank in CSV and null in Parquet/JSON. Index levels are points, not share prices or a consolidated-market return.
Constituent links document current published membership. They do not reconstruct membership before a retained historical artifact. Company registry identity, commercial claims and follows do not select index constituents or alter their weights.
Embed a linked daily-close badge or widget
Each index page provides copyable linked-image and iframe HTML. The public embed displays the actual dated close, links readers back to the permanent STN reference, and does not require an API key or free account. The widget checks for updates every fifteen minutes.
