Impact Assessment

Market Impact: The revised price bands will affect trading dynamics for these 61 securities. Tighter bands (2-5%) indicate heightened surveillance concerns and will limit intraday price movements, potentially reducing speculative activity. Wider bands (20%) suggest relatively relaxed controls. Traders and investors in these securities need to adjust strategies according to the new circuit limits.

Operational Impact: Trading members must update their systems and inform clients about the new limits. Algorithmic trading strategies may need recalibration for affected securities. The advance notice of 3 days provides minimal preparation time for system updates.

Impact Justification

Affects 61 securities with revised price bands that will change daily trading limits. Medium importance as it impacts volatility controls but applies to largely smaller/mid-cap stocks.
