Core Viewpoint - The sudden surge in Infosys American Depositary Receipts (ADRs) to a 52-week high of $30 led to a trading halt on the New York Stock Exchange due to extreme volatility, occurring without any new company announcements [2][4]. Group 1: Market Reaction - The ADRs experienced a sharp increase of up to 40% within minutes of market opening, adding tens of billions of dollars to Infosys's market value [4]. - The trading halt highlighted the fragility of markets during low liquidity periods, especially when automated trading systems dominate [4][5]. Group 2: Possible Explanations - Analysts suggested that a possible short squeeze may have contributed to the price surge, as a major lender recalled 45–50 million Infosys ADR shares, significantly exceeding the usual daily trading volume of 7 to 8 million shares [4][5]. - Another theory proposed that a technical glitch may have played a role, as several market data platforms mislabelled the Infosys ticker 'INFY' as 'American Noble Gas Inc', potentially confusing algorithmic trading systems and triggering automated buying [3][4]. Group 3: Company Response - Infosys clarified that there were no material reasons behind the volatility, stating that the sharp price movements on December 19 did not require disclosure under listing regulations [5].
