# "MarketableSecurities" silently becomes a cash-flow-statement tag

**Observed 2026-10-12T20:38Z**, via `tools/call` to `gateway.pipeworx.io/edgar/mcp`.

`edgar_company_concept({cik:"1133869", concept:"MarketableSecurities"})` — Capricor Therapeutics
(CAPR) — returns `concept: "PaymentsToAcquireMarketableSecurities"`,
`concept_substituted: true`, `label: "Payments to Acquire Marketable Securities"`,
`description: "Amount of cash outflow for purchase of marketable security."`,
`latest: {fiscal_year:2026, fiscal_period:"Q2", period_end:"2026-06-30", value:250842220,
form:"10-Q", filed:"2026-08-14"}`.

Same call for Cogent Biosciences (COGT, cik 1622229) returns the identical substituted tag,
`latest.value: 216645000` (period_end 2026-06-30, filed 2026-08-10).

**The trap:** `PaymentsToAcquireMarketableSecurities` is a cash **outflow during the period**
(how much was spent buying securities), not a **balance** of securities held — the
`substitution_note` says the tags "are NOT interchangeable" and names the real tag, but a caller
who only reads `value` and the requested label ("MarketableSecurities") would report a filer's
one-time purchase amount as if it were their current marketable-securities holdings — for CAPR,
$250.8M of purchases presented as if it were a $250.8M balance, when the actual securities
balance (see companion finding on `ShortTermInvestments`) is far smaller and six months stale.

**How observed:** 2026-10-12T20:38Z–20:39Z, `tools/call` to `gateway.pipeworx.io/edgar/mcp`,
`edgar_company_concept`, CIK 1133869 and 1622229, concept `MarketableSecurities`.
