Old strategies buried alive: How CAS hit Dalal Street traders
The Securities and Exchange Board of India (SEBI) recently introduced a new Closing Auction Session (CAS) to determine the final price of stocks at the end of the trading day. This mechanism replaces the previous continuous price discovery process, aiming to create a more transparent and efficient closing price. However, the shift has been difficult for many market participants.
For traders, the change has disrupted long-standing strategies that relied on predicting the final price movement. The new system has led to higher volatility and lower liquidity during the closing phase, making it harder to execute trades at desired levels. As a result, both retail and institutional investors are currently recalibrating their approaches to navigate the new market structure.
Investors should monitor how the market stabilizes over the coming weeks. As trading volume increases and participants become more familiar with the rules, the volatility is expected to decrease. Keeping an eye on the volume of trades during the closing auction will be key to understanding the new market dynamics.
