CAS crash: Nifty plunges 462 points in less than 30 seconds. Will Sebi’s review break trend?

The Nifty index plummeted 462 points in less than 30 seconds during Tuesday's closing auction session. This sharp decline was part of a 2% drop in indicative price, before the index recovered its losses. The volatility in the market comes as a result of concerns over the new Computer-Aided Surveillance (CAS) system, which has been proposed for changes to expiry-day settlement and trading mechanisms by the Securities and Exchange Board of India (Sebi).

Why it matters

The sudden plunge in Nifty may lead to increased volatility in the market. Sebi's review may help to stabilize the market, but its impact is uncertain.
