On December 19, 2025, Infosys’ American Depositary Receipts (ADRs) listed on the New York Stock Exchange (NYSE) experienced a sudden and dramatic surge of nearly 40% within minutes of market opening. This sharp jump briefly lifted the company’s market value by tens of billions of dollars and led the NYSE to temporarily halt trading to prevent disorderly market activity.
During the spike, Infosys ADRs touched a 52 week high of around $30, marking an unusually large move for a widely followed blue-chip stock. Surprisingly, this surge occurred without any announcements, earnings reports, or material disclosures from Infosys itself. Normally, such rapid price movements require significant company-level news, but in this case, none was present.
Experts and market observers suggest that a short squeeze may have been the main driver. A short squeeze happens when investors who had bet against a stock, known as short sellers, are forced to buy shares to cover their positions as the price rises, which in turn pushes the stock even higher. In Infosys’ case, a large volume of shares (around 45–50 million ADRs) that had been lent out to the market may have been recalled, far exceeding the usual daily trading volume of 7–8 million shares. This forced buying by short sellers created strong upward pressure on the stock in a thinly traded market, amplified by the holiday season in the U.S., which reduced overall liquidity.
Another possible factor is a technical or data glitch on trading platforms. Reports suggest that some platforms may have mislabelled the Infosys ticker “INFY,” causing automated algorithmic trading systems to execute large buy orders mistakenly. Either or both of these factors, short covering and algorithmic errors — likely contributed to the extreme price movement, even though Infosys itself had not released any news.
The NYSE’s trading halt is a standard measure to manage extreme volatility. Exchanges employ such mechanisms to prevent erratic trading and allow the market to stabilize before resuming normal operations. While this spike grabbed headlines in the U.S., Infosys’ shares traded in India did not show a corresponding surge, indicating that the event was limited to the ADR market.
Market commentators emphasized that investors should remain cautious. Sudden, unexplained spikes often result from technical market factors, and traders are advised not to react impulsively. The unusual price action underscores the risks associated with trading in thinly liquid ADR markets, where even moderate forced buying or technical errors can create extreme volatility.
In summary, the Infosys ADR surge was extraordinary: a 40% jump in minutes without fundamental news, causing a NYSE halt. The most likely explanations include a short squeeze triggered by large share recalls and possible technical glitches in market platforms. This event highlights the unique dynamics of ADR trading and the importance of monitoring liquidity and automated trading systems during periods of high volatility.
