US-listed Infosys shares experienced a dramatic jump of nearly 40% on Friday, briefly pushing ADRs to a 52-week high of $30 and forcing the New York Stock Exchange (NYSE) to halt trading due to extreme volatility. The sudden spike added tens of billions of dollars to the Indian IT giant’s market value, surprising traders as it occurred during a low-liquidity holiday session with no official company announcement.
Why the Rally Raised Eyebrows
The speed and scale of the rise caught market participants off guard. Analysts noted that such extreme swings are rare for a large-cap stock like Infosys. The NYSE trading halt highlighted the fragility of markets when liquidity is thin and algorithmic trading dominates.
Possible Short Squeeze
One leading explanation is a potential short squeeze. Reports suggest a major lender may have recalled 45–50 million Infosys ADR shares, far exceeding the normal daily trading volume of 7–8 million shares. This forced short sellers to quickly buy back shares, amplifying the upward movement.
Technical Glitch Theory
Another factor may have been a data error. Some market platforms reportedly mislabelled Infosys’ ticker ‘INFY’ as ‘American Noble Gas Inc’, while financial data and news still referenced Infosys. This mismatch could have triggered algorithmic systems to buy shares automatically, contributing to the surge.
Sector Influence
Indian IT stocks had gained minor support from Accenture’s strong earnings, but analysts agreed this alone could not justify the extreme spike in Infosys ADRs.
Company Statement
Infosys clarified that the ADR volatility on December 19 did not stem from any material events. The company noted that the NYSE triggered two volatility pauses, but no disclosures were required under listing regulations.
Takeaway
Whether caused by short covering, a technical glitch, or a combination of both, the episode highlights how quickly stock prices can swing in thin markets when automated trading and data errors interact—even for blue-chip companies like Infosys.
