BSE, NSE, Angel One shares will react to the new SEBI CAS rules - Details here

The Securities and Exchange Board of India (SEBI) has introduced new rules for the Closing Auction Settlement (CAS), a mechanism used to determine the reference price for stock market trades. Under the updated norms, the reference price will now be calculated based on the Volume Weighted Average Price (VWAP) from the last 15 minutes of the Continuous Trading Session. This change aims to improve price discovery and reduce volatility during the closing auction.
This regulatory shift is significant for market infrastructure companies like BSE and NSE, as well as trading platforms such as Angel One. Their systems and algorithms will need to be updated to comply with the new calculation methodology. For investors, the change could lead to more stable closing prices, but it may also introduce slight variations in the final settlement price compared to previous sessions.
Investors should monitor the implementation of these rules closely. The first trading day following the circular's release will be a key watch. Market participants should ensure their trading platforms are aligned with the new SEBI guidelines to avoid any execution errors.
