 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# ARCH CAPITAL GROUP LTD. (NASDAQ: ACGL) — 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 ACGL, with ISIN USG0450A1054. The LEI is not on the record, as no GLEIF record carries the exact legal name in jurisdiction US.

The issuer is listed and not halted.\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 filings comprise 40 directors' dealings, 21 regulatory filings, 9 corporate news, 8 results, 3 AGM or EGM, 3 director changes and 2 prospectuses.

The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. The domicile change is not on the record, as EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, as the exchanges' tier transfers are not EDGAR filings. The issuer is listed and not halted.\n\n## Orderability\n\nThe outcome is not determinable, as the chapter's orderability section carries no client categories and so the outcome cannot name its client category.
