Infosys ADRs(Infosys ADRs)在2025年12月19日猛涨了50%, 原因是数据错误贴错标签, 在逆转前触发算法交易混乱。 Infosys ADRs spiked 50% on Dec. 19, 2025, due to a data glitch mislabeling its ticker, triggering algorithmic trading chaos before reversing.

Infosys ADRs(Infosys ADRs)在2025年12月19日猛增近50%, 在极端波动和多重交易停顿中达到30美元的峰值, Infosys ADRs surged nearly 50% on December 19, 2025, reaching a peak of $30 amid extreme volatility and multiple trading halts, driven by a technical glitch involving a ticker-mapping error that misled algorithmic trading systems. 此次激增在没有公司新闻或基本面变动的情况下发生，归因于数据流异常，Infosys的股票代码（INFY）在部分平台上错误标注为“American Noble Gas Inc”，引发了自我强化的买股狂潮。 The spike, which occurred without any company news or fundamental changes, was attributed to a data-feed anomaly where Infosys’s ticker (INFY) was incorrectly labeled as "American Noble Gas Inc" on some platforms, triggering a self-reinforcing buying frenzy. 年终星期五的流动性低加大了这一影响,交易量远远超过了正常水平。 Low liquidity on a year-end Friday amplified the effect, with trading volume far exceeding normal levels. 涨势迅速反转，ADR收盘上涨5.7%，而Infosys在印度上市的股票仅略有上涨。 The rally quickly reversed, and ADRs closed up 5.7%, while Infosys’s Indian-listed shares rose only slightly. 这一事件凸显了自动化交易、数据完整性和发展成果评估市场脆弱性方面的系统性风险,促使监管审查。 The incident highlighted systemic risks in automated trading, data integrity, and ADR market fragility, prompting regulatory review.
