The $25 Billion Phantom Inside the Infosys ADR Trading Halt
NEW YORK/BENGALURU – Investors on Wall Street were left bewildered on Friday as American Depositary Receipts (ADRs) of the Indian IT giant Infosys experienced a staggering, unexplained intraday spike. Within minutes of the opening bell, INFY shares surged from a previous close of $19.18 to a 52-week high of $30.00, representing a nearly 40% to 50% gain that added tens of billions of dollars to the company’s market capitalization on paper.
The Trading Halt
The sudden vertical move triggered multiple Limit Up-Limit Down (LULD) volatility halts by the NYSE. These automated circuit breakers are designed to prevent disorderly trading during periods of extreme price swings. After the cooling-off periods, the ADR eventually retraced most of its gains, settling at $20.22 (up 5.42%) by the close of the session.
Why Did It Happen? Two Leading Theories
While the move occurred amidst a broader rally in the IT sector following positive results from Accenture, analysts suggest the scale of the Infosys surge was driven by external technical factors rather than company fundamentals:
The "Ticker Mapping" Glitch: Several reports indicated a bizarre technical error where financial data providers (including Zacks and MarketBeat) erroneously identified the "INFY" ticker as "American Noble Gas Inc." This mismatch likely confused high-frequency trading (HFT) algorithms, which interpreted the data discrepancy or "mispricing" as a massive buy signal.
The Short Squeeze & Share Recall: Market rumors suggest a major lender may have recalled 45–50 million Infosys ADR shares. In a low-liquidity holiday session, this forced short-sellers to scramble for shares at any price, creating a classic "short squeeze" feedback loop.
Infosys Responds
In a formal clarification filed with the exchanges on Saturday, December 20, 2025, Infosys stated that there were "no material events" that required disclosure. The company confirmed that the volatility was an external market event and not linked to any undisclosed corporate developments or earnings updates.
The "ADR Bridge" Risk
The incident has highlighted the unique risks of ADRs. Because they trade in New York while the primary Indian markets (NSE/BSE) are closed, there is often no "anchor" to steady the price during a technical glitch. While the ADR soared 40% in New York, Infosys shares in Mumbai remained largely stable, closing with only a minor 0.7% gain.
