summary: The corrections registry

content:
application/json:
schema:
$ref: '#/components/schemas/Corrections'
example:
count: 12
newest: '2026-10-08'
kinds:
reading: How an issuer file or a filing was read
keys: How securities are keyed
ticker: A ticker reused or moved
prices: Price data
flows: ETF flows
entries:
- id: 2026-10-08-flows-merger-ranked-as-selling
date: '2026-10-08'
kind: flows
title: A merger was ranked as ETF selling
scope:
- flows
tickers:
- BLFS
- RGEN
tickers_complete: true
before: 'The ETF flows of the first night ranked BLFS among the largest net reductions of the day: the funds'' BLFS lines left their files when BLFS merged into RGEN, which read as sales.'
after: A corporate action is published as one, dated at the first close where any of its lines were flagged, and its securities leave the rankings of that close.

- id: 2026-10-04-spcx-ticker-moved-to-spck
date: '2026-10-04'
kind: ticker
title: A fund was served under a ticker that now names a company
scope:
- fund
- sec
- holders
tickers:
- SPCX
- SPCK
tickers_complete: true
before: The SPAC and New Issue ETF trades as SPCK, and Nasdaq Trader's directory of 2 October 2026 gives SPCX to Space Exploration Technologies' Class A common stock. The SEC's ticker file still gave the fund's series SPCX, so /api/v1/fund/spcx.json served the fund's filing under the company's ticker.
after: The fund is served as SPCK, from the same filing, and SPCX's one file is the company's stock file under /api/v1/sec/. A fund whose every ticker now names a company of another name is refused.

- id: 2026-10-04-ishares-weights-from-market-values
date: '2026-10-04'
kind: reading
title: iShares lines under 0.005% were read as 0.00%
scope:
- fund
- sec
- holders
- compare
- history
tickers:
- ITOT
tickers_complete: false
before: 'iShares prints each weight rounded to two decimals, so a line under 0.005% of a fund read 0.00%: 1,287 of ITOT''s 2,448 lines on its file of 1 October 2026, which the overlap figures left out.'
after: Each weight is computed from the row's market value, to six decimals, when the market values agree with the printed weights within the rounding. The overlap figures keep 2,440 lines of that file, and ITOT's overlap with VTI's file of 31 August 2026 went from 93.0% to 95.4%. The holdings history reads the step to the first file weighted this way as a restatement, not as trades.
