    Opening Match

    On listing day, shares are listed on NSE/BSE and open for trading.

    The opening price is determined by a call auction matching buyers and sellers.

    Good Point

    The opening price can be higher or lower than the IPO price depending on demand.

    Circuit Filters

    Circuit filters are price bands set by exchanges to prevent extreme price swings.

    They limit daily price movement to a certain percentage above or below the previous day's closing price.

    Warning

    If price hits upper or lower circuit, trading may be paused or halted.

    Liquidity and Volatility

    Newly listed stocks can be volatile due to hype and limited supply.

    Investors should be cautious and avoid chasing listing day price jumps.

    Check Points

    Watch for liquidity (trade volume). Avoid decisions based solely on listing day gains.
