In a move that left Wall Street analysts and Indian investors equally bewildered, the American Depositary Receipts (ADRs) of Indian IT giant Infosys (NYSE: INFY) experienced a massive "flash jump" on Friday, December 19. Within minutes of the opening bell, the stock skyrocketed by nearly 40%, hitting a 52-week high of $30, before the New York Stock Exchange (NYSE) was forced to halt trading.
The "Flash Jump" Phenomenon
A "flash jump" refers to a rapid, often unexplained spike in a stock's price within an extremely short timeframe. In the case of Infosys, the sudden surge added billions of dollars to its market valuation momentarily. However, market regulators and analysts quickly clarified that the rally was not driven by any company-specific news or earnings reports, but rather by a combination of technical anomalies and market mechanics.

The Science Behind the Surge: 3 Key Factors
According to analysts and exchange reports, three primary triggers fueled this unusual price action:
1. The "Fat Finger" & Data Error Theory
Reports suggest a "bizarre" technical glitch where several financial data providers mislabeled the INFY ticker as an unrelated entity ("American Noble Gas Inc."). This discrepancy, combined with a potential "Fat Finger Trade"—where a trader accidentally enters an order for a much larger quantity than intended—is believed to have sparked the initial movement.
2. Algorithmic Feedback Loops
Modern markets are dominated by computer-driven Algorithmic Trading. These systems are designed to detect sudden price momentum. When the initial error occurred, high-frequency algorithms likely interpreted the price move as a legitimate signal to buy, triggering a massive wave of automated purchases that amplified the spike in a low-liquidity environment.
3. The "Short Squeeze"
As the price began to climb, investors who had "shorted" the stock (betting that the price would fall) faced mounting losses. To exit their positions and limit damage, these investors were forced to buy back shares immediately. This process, known as a Short Squeeze, creates a "snowball effect" of buying pressure, pushing the price even higher.
