Infosys ADR spike traced to data error, not fundamentals
Infosys ADR spike traced to data error, not fundamentals
A sharp, unexplained surge in Infosys ADRs was linked to data-feed errors and algorithmic trading, not company news.
A dramatic move in Infosys ADRs at the US market open drew immediate attention to cross market trading dynamics in a heavily automated environment. Infosys ADRs surged more than 38% in minutes after the US market open on December 19, briefly trading near $27, while Infosys and its parent markets in India showed no corresponding fundamental news to justify the spike.
Industry observers traced the jump to a data feed mismatch where the INFY ticker was mis-mapped to unrelated entities on several platforms, yet Infosys specific data remained attached. In practice, algorithmic traders scanning for mispricings treated the mismatch as an anomaly and placed rapid buy orders, feeding a self-reinforcing rally in a thin ADR market.
Volatility controls kicked in as the NYSE imposed Limit Up-Limit Down halts after prices breached allowed bands. When trading resumed, the ADR pulled back heavily, retreating from the intraday highs to levels far below the early surge.
Across the Atlantic, Infosys shares in Mumbai rose only modestly, underscoring a stark disconnect between the US-traded instrument and the company’s fundamentals on that day.
Experts caution that the episode highlights the risks of automated cross-market price discovery and the importance of data quality in a data-driven market. Regulators are increasingly focused on tick-level data integrity and the resilience of trading venues as algorithms take on larger roles.
