Former MP Somaiya urges SEBI to temprarily suspend CAS after sharp Sensex volatility

Former Member of Parliament and broker Somaiya has written to the Securities and Exchange Board of India (SEBI) requesting a temporary suspension of the Closing Aggregated Settlement (CAS) mechanism. This system is used to settle trades at the end of the day. Somaiya argues that the current volatility in the market is being exacerbated by this process, which can lead to sudden price swings.
For retail investors, this news highlights the ongoing debate over market stability. The proposed suspension aims to prevent large, last-minute price movements that can catch traders off guard. If SEBI accepts the request, it could lead to a temporary change in how trades are settled, potentially making the market environment more predictable for the short term.
Investors should watch for an official response from SEBI regarding this request. The regulator will need to weigh the benefits of reducing volatility against the operational complexities of changing settlement rules. Until a decision is made, market participants should remain cautious and monitor price action closely.
