纳斯达克计划在今年 12 月 6 日推出每周 23 小时、5 天的美股交易安排,前提是相关基础设施升级按期完成。此举显示,美国主要交易所正继续拉长交易时段,以承接跨时区资金需求,并回应加密市场全天候交易带来的压力。

交易时段延长至 23/5

按照纳斯达克披露的新安排,交易将从每周日晚上持续至周五晚上,每天保留 1 小时停市窗口,用于交易日切换和系统维护。现行时段则为美东时间凌晨 4 点至晚上 8 点,核心交易时段仍是上午 9 点 30 分至下午 4 点。

纳斯达克表示,新的交易机制此前已获得美国证券交易委员会批准,当前上线时间主要取决于其证券信息处理系统(SIP)能否完成更新。

夜间交易将设限制

为应对夜间流动性偏低和价格波动放大的问题,纳斯达克计划在夜间交易时段加入额外限制措施,包括通过价格带拒绝波动过大的成交申请,并对标准市价单设置限制。

这意味着交易时段虽然接近全天候,但并不会完全复制加密市场的连续交易模式。传统证券市场仍需在清算、报价和风险控制环节保留更多约束。

传统交易所加快追赶

近年多家传统平台已开始延长交易时间。Robinhood 和盈透证券自 2023 年起,已通过另类交易系统为部分股票提供 24/5 交易。纽约证券交易所也在推进更长时段的交易安排,其中常规股票 22/5 交易已获批,预计今年上线;其代币化交易场所申请仍在等待监管放行。

纳斯达克总裁 Tal Cohen 表示,全球投资者对美国股票的需求持续上升。根据其披露,2019 年至 2024 年间,海外对美股交易需求增长 97%。在科技股和 AI 相关行情推动下,纳斯达克综合指数今年以来已上涨逾 13%,并处于历史高位附近。

除了承接全球订单,延长交易时间也被视为对资金流向变化的回应。随着加密资产、代币化产品以及 Hyperliquid 等全天候数字市场吸引更多散户,传统交易所正尝试缩小与 24/7 市场之间的时间差。
