 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Eaton Vance National Municipal Opportunities Trust (NYSE: EOT) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Eaton Vance National Municipal Opportunities Trust, listed on the NYSE under ticker EOT, with ISIN US27829L1052 and LEI 54930084Z1GHZMB5XL81. The security type is non-operating entity type (other). The segment, sector and jurisdiction are not on the record. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 10 filings in the window 2025-11-08 to 2026-11-08, across 10 filing days: 1 agm_egm and 9 regulatory_filing. The median gap between filing days is 24 days. The latest filing is dated 2026-10-26 and is a regulatory_filing, 13 days before the record date of 2026-11-08. The NYSE median is 64.0 filings, a median cadence gap of 6.0 days and a median latency of 4.0 days, against which this issuer's figures are as stated above. The sector median is not on the record for the US market.\n\n## Auditor\n\nThe auditor is not on the record, because no dei:AuditorName tag is carried on the latest annual report cover. No auditor location is on the record and no auditor changes are recorded.\n\n## Events and halts\n\nThe record carries no listing, delisting, name change or segment move 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 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 read, and the count is 0.\n\n## Open research\n\nNo openly published research notes were found, and the count is 0.\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 sealed years 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://mapping.gleif.org/api/v2/isin-lei/latest (identity.isin)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://data.sec.gov/submissions/CIK0001454741.json (identity.name)\n- https://mcp.us-cm-kg.ai/events/NYSE/EOT (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/NYSE/EOT (the record)\n",
