New Delhi, Dec 20 (NationPress) A potential data-feed glitch and algorithm-driven trading—rather than any specific company-related news—appear to have ignited a remarkable increase of around 50 percent in Infosys Ltd’s American Depository Receipts (ADRs), according to a recent report.
The Chronicle Journal highlighted that the surge in Infosys ADRs on December 19, 2025, was likely the result of a ticker-mapping mistake across various financial data platforms, which misled automated trading systems and initiated a self-perpetuating buying frenzy in a lightly traded asset.
This abrupt price movement led to multiple Limit Up–Limit Down volatility halts on the New York Stock Exchange, the report noted.
Several data providers had mistakenly linked the “INFY” ticker to an unrelated entity, while still associating it with Infosys-specific metrics and news.
This error caused algorithmic models to perceive a pricing anomaly, prompting aggressive buy orders, with the effect amplified by low liquidity and thin trading volumes.
The ADRs, which had closed the previous trading session at approximately $19.18, surged to as high as $27 within minutes of the market opening before volatility measures were activated to stabilize prices. Notably, there was no corresponding reaction in the company's shares listed in India, as per the report.
This market anomaly highlights the vulnerabilities of ADRs, which operate when domestic markets are closed, exposing the trading system to potential data errors, liquidity issues, and automated trading feedback loops.
US exchanges and regulators are anticipated to investigate this anomaly to determine if data inconsistencies played a significant role and whether the volatility safeguards worked as intended.
In the meantime, US tech giant Microsoft has recently announced strategic partnerships with IT firms, including Infosys, to deploy over 50,000 Microsoft Copilot licenses, collectively exceeding 200,000 licenses, thereby accelerating the adoption of agentic AI.
This partnership emphasizes the transformative potential of agentic AI—intelligent systems capable of taking initiative, making decisions, and generating insights autonomously—aiming to unlock new paths for growth and competitiveness.
Point of View
My perspective on this issue is clear. The recent surge in Infosys ADRs emphasizes the critical need for robust data integrity and transparency in financial markets. This incident not only highlights the vulnerabilities present in automated trading systems but also underscores the importance of regulatory oversight to safeguard investors. We must remain vigilant to ensure that such anomalies do not undermine market confidence.
