Retail traders have called for a one-day boycott of stock market trading on August 12 to protest the introduction of the Closing Auction Session (CAS) by the Securities and Exchange Board of India (SEBI). A social media post with nearly 1.5 lakh followers urged a 'no trade day' against CAS and the securities transaction tax (STT), while another with over 15,000 followers cited rising taxes and regulations hurting retail traders. SEBI introduced CAS on August 3 for about 200 stocks traded in derivatives, replacing the earlier volume-weighted average price (VWAP) method. Regulators say it improves benchmark reliability and reduces manipulation, but traders allege it has caused wide divergence between the Nifty and Sensex indices and led to substantial losses from unusual closing price swings.
