A sharp selloff on Thursday erased nearly ₹5 lakh crore in investor wealth, dragging the Nifty 50 below the 25,000 mark intraday and raising widespread caution ahead of Friday’s trade. SEBI-registered analyst Mayank Singh Chandel referred to the day as a 'terrible Thursday', citing a Sensex drop of over 800 points and the Nifty falling below 24,900.
