Sebi bars two entities for 'manipulating' CAS
Economic Times 1 hr ago·20 Aug 2026, 12:56 am
The Securities and Exchange Board of India (Sebi) has barred two entities from the securities market for allegedly manipulating the Sensex closing auction. The regulator found that Copthall Mauritius Investment and Mansi Share and Stock Broking engaged in sharp, unusual trading activity on August 13. This activity was designed to influence the index's closing price, which is used to settle outstanding Sensex options contracts.
This action highlights the regulator's strict stance against market manipulation, particularly in the new closing auction session. By preventing these entities from trading, Sebi aims to ensure fair price discovery and protect the integrity of the market. The ban serves as a warning to other market participants to adhere to fair trading practices.
Investors should monitor Sebi's enforcement actions closely. A crackdown on manipulation can increase market stability and confidence. For now, the Sensex is expected to trade normally, but this case reinforces the importance of a transparent and orderly market structure for all retail investors.
