(NASDAQ: ACGLN) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is ARCH CAPITAL GROUP LTD., listed on NASDAQ under ticker ACGLN, with ISIN US03939A4040 and LEI 549300AYR4P8AFKDCE43. Its security type is Corporate, its sector is 6331 Fire, Marine & Casualty Insurance, and its listing status is listed, not halted. Its segment and jurisdiction are not on the record.\n\n## The disclosure read\n\nThe record holds 86 filings across 46 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 4 days, and the latest filing is dated 2026-11-05, 3 days before the record date, and is of type corporate_news. On NASDAQ the median cadence gap is 6.0 days, the median filings are 52, and the median latency is 5.0 days. In the sector 6331 Fire, Marine & Casualty Insurance the median cadence gap is 5.0 days, the median filings are 80, and the median latency is 3 days. The window holds 40 directors_dealings, 21 regulatory_filing, 9 corporate_news, 8 results, 3 agm_egm, 3 director_change and 2 prospectus filings.\n\n## Auditor\n\nThe auditor is not on the record, because the latest annual report cover carries no dei:AuditorName tag, and its location is not on the record. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting, name change, or segment move lines. The domicile change is not on the record, since EDGAR states no dated change of state of incorporation on a filing line, and the segment move is not on the record because the exchanges' tier transfers are not EDGAR filings. The halt flag is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, because the chapter's orderability section carries no client categories and so the outcome cannot name its client category. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations pages that were read.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded. A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe issuer's years sealed are 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04, and the live record began on 2026-09-12.\n\n## Sources\n\n8 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://www.sec.gov/files/company_tickers_exchange.json (identity.exchange)\n- https://www.sec.gov/data-research/sec-markets-data/fails-deliver-data (identity.isin)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://data.sec.gov/submissions/CIK0000947484.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/ACGLN (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/ACGLN (the record)\n",
