What happens to a stock under surveillance?

When a stock is under surveillance (ASM/GSM) by exchanges, it faces stricter rules like higher margins, reduced price bands (e.g., 5%), and mandatory delivery (T2T), meaning no intraday trading, to curb volatility and manipulation, with Ventura Securities providing alerts and applying these restrictions to protect investors from abnormal price swings and manipulation.
What Happens to the Stock/Trading
Increased Margins: Higher collateral is required for trading.
Trade-to-Trade (T2T) Settlement: All trades must result in delivery, preventing intraday profit booking and short selling.
Price Bands: Daily price movement limits (e.g., 5%) are imposed to control volatility.
Restricted Trading: Intraday trading is often banned, and trading frequency may be limited.
Investor Nudges: Platforms like Ventura or Paytm Money show alerts or require confirmation before you can trade.
