Infosys ADR Spike: Data Glitch, Algo Trading Blamed by Chronicle Journal

• Infosys ADRs saw a sudden near-50% spike on December 19, 2025, in early US trade.
• The Chronicle Journal attributes the surge to a suspected data-feed anomaly and ticker-mapping error, confusing automated trading systems.
• "INFY" ticker was reportedly mis-mapped to an unrelated entity by data providers, triggering aggressive algorithmic buy orders.
• Low liquidity and thin trading volumes magnified the impact, leading to LULD halts on NYSE before prices retreated.
• The incident highlights ADR vulnerabilities to data errors and automated feedback loops; US regulators are expected to review.

Why It Matters: Infosys ADR spike likely caused by data glitch and algorithmic trading, not company news.
