Before the Market Wakes: Why Extended Trading Hours Is the Dawn Run Capital Markets Can’t Skip

Extended Trading Hours (ETH) is no longer a peripheral session — it is the opening phase of a more continuous market structure.

As U.S. equities move toward 23x5 trading, the implications reach far beyond access. Liquidity formation, supervision models, operational resilience, and client expectations are evolving — gradually, but decisively.

• Why ETH represents a structural shift in how markets operate
• Early indicators already emerging across liquidity and participation patterns
• The risk, compliance, and surveillance challenges firms must address
• The operational redesign required across the trade lifecycle
• A practical roadmap for preparing before overnight volumes scale

The quiet hours are disappearing. The firms that prepare now will define the next phase of market structure.
