What the GMP means for Tonbo Imaging
Grey Market Premium (GMP) is the unofficial premium at which an IPO's shares change hands before listing. A positive GMP signals bullish pre-listing sentiment, but it is unregulated, volatile and routinely diverges from the actual listing price in both directions — treat it as a thermometer, never a forecast.
