The Security Traders Association of New York (STANY) will hold its 90th Markets Conference, with the agenda built around the shifts now running through US equity market structure.

The conference number itself is the anchor fact: this is the 90th edition of an event that has tracked the mechanics of trading through nine decades of structural change — from floor-based intermediation to electronic routing, Reg NMS, and the current debate over tick sizes, auction mechanics and access fees.

STANY positioned the program around "market shifts," a framing that arrives as desks face a series of live regulatory and operational questions. Conference programming of this kind typically serves as a temperature check for what buy-side and sell-side execution teams consider urgent — and the agenda signals where practitioner attention is heading next.

For execution desks, industry conferences function less as news events than as workflow inputs. They set the calendar for compliance planning, vendor evaluations and peer benchmarking. A 90th-anniversary edition tends to draw a heavier roster of exchange, regulator and buy-side speakers, which matters for teams that need direct access to rulemaking and venue officials outside formal comment-letter channels.

What the announcement establishes is the event, its milestone edition and its thematic focus on market change. What it does not yet establish is the speaker list, session breakdown or specific regulatory topics — those details will determine whether the program addresses execution-relevant questions such as order routing economics, market data costs or the SEC's equity market structure agenda in concrete terms.

Traders Magazine carried the announcement. Watch for the full agenda release, which will show whether the milestone edition translates the "market shifts" theme into named regulators, quantified structural debates and actionable sessions for execution and compliance teams.
