Regulatory Changes

The price band mechanism limits the maximum price movement (up or down) that a security can experience during a trading day. Tighter price bands (2%, 5%) indicate higher surveillance and restricted price movement, while wider bands (20%) allow more normal trading. This measure is typically applied to securities exhibiting unusual price volatility, low liquidity, or other risk characteristics requiring enhanced monitoring.

Compliance Requirements

  • Trading members must implement the revised price bands in their trading systems before October 27, 2025
  • All trades in the affected securities must comply with the new price band limits from the effective date
  • Members should update their risk management systems to reflect the new bands
  • Client communication may be necessary for active traders in these securities

Important Dates

  • Notice Date: October 24, 2025
  • Effective Date: October 27, 2025
  • Implementation window: 3 days from notice to effective date

Impact Assessment

Market Impact: The revised price bands will affect intraday volatility and trading patterns in these 57 securities. Tighter bands (2%, 5%) will limit price discovery and may reduce liquidity, while protecting against excessive volatility. Securities with 2% bands (Anirit Ventures, Genesis Ibrc) face the most restrictive trading environment.

Investor Impact: Active traders and investors in these securities need to adjust their trading strategies to account for daily price movement limits. Stop-loss and target prices must be set within the applicable price band. Securities may hit upper or lower circuit limits more frequently under tighter bands.

Operational Impact: Brokers and trading members must update their systems, algorithms, and risk management frameworks to incorporate the new bands. Client advisories may be required for holders of these securities to manage expectations regarding price movement constraints.

Impact Justification

Price band changes affect trading limits and liquidity for 57 securities, primarily impacting traders and investors in these specific scrips. The varied bands (2%-20%) indicate different risk levels assigned to each security.
