BSE Tightens Grip: Circuit Filters Changed for 38 Stocks to Curb Market Manipulation

• BSE has adjusted price bands for 38 stocks and implemented strict monitoring measures to prevent artificial price surges or drops.
• Measures include circuit filters, special margins, and trade-to-trade, targeting stocks with unusual activity and rumor-driven trading.
• Special margins (up to 75%) are imposed on stocks with sharp, unsubstantiated surges to curb speculative trading.
• Circuit filters are reduced (to 2%, 5%, or 10%) for illiquid stocks to prevent significant price changes from small trades.
• The changes, effective January 27, 2026, aim to protect retail investors and increase market transparency.
