Jamie Selway is the Director of the U.S. Securities and Exchange Commission’s Division of Trading and Markets (appointed June 17, 2025).
The Division establishes standards for fair, orderly, and efficient markets and oversees broker-dealers, exchanges, clearing agencies, transfer agents, and self-regulatory organizations; it also advises on rulemaking, provides guidance, and conducts market surveillance and risk monitoring.
STAC refers to events run by the Security Traders Association (notably the Security Traders Association of Chicago); its conferences (e.g., Mid‑Winter Meeting, STAC Summits) attract traders, buy‑side and sell‑side trading professionals, compliance/legal and technology staff, exchange and clearing representatives, and market-structure and data vendors.
Yes — the SEC page for the speech includes Selway’s full prepared remarks (transcript) posted by the SEC at the linked URL.
No major new SEC rules, formal guidance, or enforcement actions were announced in the remarks; they were prepared remarks on market structure and the Division’s priorities rather than a rulemaking or enforcement notice (no new rule text or enforcement filing was released there).
In context, the phrase “Commission of Big Shoulders” is a rhetorical framing Selway used to describe the SEC’s role and responsibilities in standing firm to support resilient, fair markets and to shoulder regulatory responsibilities — not a reference to a formal program or office.
Practically, the remarks signal Division priorities (market resiliency, fairness, oversight of trading intermediaries and technology) that could influence future rulemaking focus, supervisory priorities, and industry practices — prompting broker‑dealers, exchanges, and investors to monitor SEC rule proposals and compliance expectations, but they did not themselves create immediate regulatory changes.
