The Hang Seng Tech Index entered a notable correction phase in late October 2025, setting the stage for a demanding decision-training replay. This period represented a test of risk management and emotional discipline as the technology sector faced headwinds. Participants would navigate a declining market environment requiring careful position sizing and clear exit strategies.
The index declined from 6.15 to 5.5 over 38 trading days from October 10 to December 4, 2025, representing a total decline of 10.6%. The maximum drawdown reached 14.3%, with the largest single-bar move hitting 4.2%.

This correction tested the ability to manage downside risk while maintaining strategic composure.
The replay offers valuable lessons in several dimensions. Process-wise, it emphasizes the importance of predefined rules for entering and exiting positions during downturns. Risk management becomes tangible when confronting a 14.3% drawdown in simulated capital, forcing participants to experience the psychological weight of sustained losses. Psychologically, maintaining discipline when facing consistent pressure reveals how emotion can distort decision-making. This historical correction from the 2020s serves as a stark reminder that declining markets, while uncomfortable, provide essential training grounds for developing resilient trading frameworks.
