SRO Monitor Digest

Texas Stock Exchange (TXSE) is joining the industry-wide Symbology Plan, which governs how securities ticker symbols are selected and reserved among exchanges. This is a routine administrative step that took effect immediately — it simply means TXSE has met the basic requirements to operate as a registered exchange and can now claim and reserve ticker symbols like any other exchange. In practice, this filing signals that TXSE is moving forward as an operational equity exchange and will be competing in the U.S. equity market alongside IEX and other incumbents.

Texas Stock Exchange (TXSE) and FINRA have filed a standard regulatory allocation agreement under Rule 17d-2, which would let FINRA handle examination and enforcement of broker-dealers that are members of both TXSE and FINRA, avoiding duplicative oversight. This is a routine administrative step that every new exchange must complete before it can operate — the SEC is now soliciting public comments and can approve the plan after February 23, 2026. For market participants, this simply means broker-dealers joining TXSE won't face redundant regulatory exams on overlapping rules; TXSE retains responsibility for its own marketplace surveillance and any rules unique to its exchange.
