Shares of Coffee Day Enterprises surged more than 13% on Monday, Dec 15, after the stock exchange revised its circuit limit from 5% to 20%, allowing a wider trading range and triggering fresh buying interest.
The change in price band comes under the BSE and NSE’s surveillance framework, which adjusts circuit limits depending on volatility, liquidity, and unusual price movement.
A wider price band gives traders more room to buy or sell, often resulting in stronger intraday momentum — which is what helped Coffee Day Enterprises rally sharply today.
Exchanges also monitor such movements closely. If volatility escalates again, they can introduce additional measures such as:
-
Moving the stock to the trade-to-trade (T2T) segment
-
Imposing special margins
-
In extreme cases, suspending a share or member
By increasing the circuit filter to 20%, the exchange effectively signalled that the stock could trade more freely, and buyers quickly pushed the price higher.
