Impact Assessment

Trading Impact: The revised price bands will significantly restrict intraday price movements for affected securities. Stocks with tighter bands (1-5%) will experience severe limitations on volatility, potentially reducing trading volumes and liquidity.

Investor Impact: Investors holding these securities will face limited ability to exit or enter positions at desired prices within a single trading session. Large orders may need to be executed over multiple days.

Market Operations: The 1% band on SER Industries and 2% band on Chambal Breweries indicate serious volatility concerns by the exchange. The 5% band applied to 15 securities suggests widespread surveillance actions across smaller-cap stocks.

Surveillance Context: These measures are typically applied to stocks exhibiting unusual price movements, low liquidity, or potential manipulation concerns. The tight restrictions aim to protect investors from excessive speculation.

Impact Justification

Price band revisions affect trading flexibility for 37 securities, with significant restrictions for some stocks (1-2% bands indicating high volatility concerns), impacting investor trading strategies.
