The fear of short squeezes is emerging again
One explanation that was widely cited in the market was a short squeeze. Such moves occur when a stock’s price rises sharply over a short period of time, forcing investors who had bet against the stock to buy them back at higher prices to limit losses. Those urgent purchases increase demand, drive prices higher and trigger further short-covering in a self-reinforcing cycle. Traders cited by Moneycontrol said a major lender had recalled 45 to 50 million Infosys ADR shares that had been lent in the market. This figure would be much higher than the typical daily trading volumes of around seven to eight million shares. In a tight market, a recall of that magnitude could have forced short sellers to scramble for shares, accelerating the rise.
A technical glitch adds fuel
A separate theory focused on a technical error that might have led to algorithmic purchases. According to a report by The Chronicle Journal, multiple data providers mislabeled the Infosys ticker by tagging ‘INFY’ as ‘American Noble Gas Inc’ on platforms such as Zacks and MarketBeat.
The ticker mapping glitch had reportedly started days earlier and caused automated trading systems to go haywire. Although the company name was incorrect, the financial figures and news headlines associated with the ticker continued to refer to Infosys, including details of its investments in artificial intelligence and its market capitalization of approximately $75 billion. Systems designed to detect momentum shifts or apparent mispricing may have interpreted the discrepancy between the company label and the underlying data as a strong buy signal, reports said. That likely led to aggressive automated buying, amplifying the rally in an already cash-strapped market.
Industry background offers limited explanation
Indian IT stocks also moved higher after Accenture reported better-than-expected quarterly results after Indian markets closed on Thursday, providing some support to sector sentiment. However, this development alone fell short of explaining the magnitude of the change in Infosys’ ADRs.
The trading halt on the NYSE highlighted how quickly volatility can increase when shorting, data errors and automated trading intersect. Whether caused primarily by forced short-covering, a technical glitch, or a combination of the two, this episode is a reminder that even large, widely held stocks can experience extreme price swings when liquidity diminishes and market systems fail.
Infosys response
India’s second-largest IT services company addressed the episode on Saturday, saying there were no material developments behind the sharp move.
