CIRCULAR
SEBI/HO/MRD/TPD-1/P/CIR/2024/58 May 24, 2024
To
All Stock Exchanges
(Except Commodity Derivatives Exchanges)
Sir/Madam,
Enhancement of Dynamic Price Bands for scrips in the Derivatives segment
1. For scrips excluded from the requirement of price bands, a mechanism of
dynamic price bands (or operating range) has been implemented by Stock
Exchanges. The present formulation for dynamic price band for underlying in
cash market and derivatives contracts on them as per Clause 2.5 of Chapter 1
and Clause 1.10.3 of Chapter 4 of SEBI Master circular dated October 16, 2023
for Stock Exchanges and Clearing Corporations and existing practice, is
summarized below:
a. Underlying in cash market and futures contracts have start of the day
price band as 10% of yesterday’s closing price of that scrip/contract as
a dynamic price band.
b. These price bands can be flexed by 5% of yesterday’s closing price
during the day as many times as required subject to the following
conditions followed by the cooling off period
c. In the event market trends in either direction, the conditions precedent
for flexing is minimum of 25 trades to be executed with minimum 5
different UCCs on each side of the trade at or above 9.90% and so on.
That is to say if 25 trades from 5 different UCCs on each side occurred
at or above 9.90%, the dynamic price band is flexed to 15%, if 25 trades
from 5 different UCCs on each side occurred at or above 14.90%, the
dynamic price band is again flexed to 20% etc.
d. Cooling Off: After the aforesaid conditions are satisfied, a cooling off
period of 15 minutes is provided before the price band is flexed. It may
be noted that during the cooling off period, trading continues in the
underlying scrip / futures contracts albeit with the prevalent price
floor/ceiling as applicable.
e. The options contracts continue to trade in their applicable price bands
when underlying cools off after hitting the price band.
f. If price band in cash market is flexed for a scrip, then the price band for
the futures contracts is also flexed.
g. Whenever price band of a scrip or futures contracts is flexed in one
direction (i.e. in the direction of price trend), the price band on the other
side remains unchanged.
2. Principles behind construct of dynamic price band, existing formulation and the
need for enhancement were summarized by SEBI in its consultation paper
dated May 20, 2023 titled Price Band formulation for scrips in Equity Derivatives
segment to strengthen volatility management and minimise information
asymmetry. On the basis of feedback received from various stakeholders,
discussions held with Secondary Market Advisory Committee of SEBI and
Stock Exchanges, the modified framework for price band formulation for scrips
in the derivatives segment is provided below.
(A) Enhancing conditions precedent before flexing price band
3. To take care of issues related to sudden price movement / fat finger error etc.,
the conditions precedents, as mentioned at Para 1(c) of this Circular, are
enhanced to 50 trades, 10 unique UCCs and 3 trading members on each side.
(B) Aligning price bands between underlying and its futures contracts
4. In modification of the requirement mentioned at Para 1(f) of this circular,
exchanges shall ensure that when conditions for flexing the price bands are
satisfied on either underlying in cash market or current month futures contracts
on any exchange, the price band would be flexed for the scrip and all the futures
contracts on this scrip across all exchanges at the end of subsequent cooling
off period.
(C) Strengthening Volatility/Risk Management and minimizing information
asymmetry for extreme price movement
5. As scrip price keeps trending in one direction, it is required to provide adequate
time to market participants to assimilate any company / market specific news
flow thereby resulting in orderly price movement while reducing strain on
settlement systems on account of extreme price movements in one direction.
Accordingly, in modification of the requirement mentioned at Para 1(b) and 1(d)
of this circular, it has been decided that the cooling off period of 15 minutes
would be increased and the flexing percent of 5% would be decreased, in a
calibrated manner, as follows:
a. For the first two instances of flexing, the price band would be flexed by
5% of yesterday’s closing price after the cooling off period. This cooling
off period would be 15 minutes if conditions for flexing are satisfied
before last half an hour of trading and 5 minutes if conditions for flexing
are satisfied in the last half an hour of trading.
b. For subsequent two instances of flexing, price band would be flexed by
3% of yesterday’s closing price after the cooling off period of 30 minutes.
c. For subsequent instances of flexing, price band would be flexed by 2%
of yesterday’s closing price after the cooling off period of 60 minutes.
(D) Sliding price band on account of flexing
6. In modification of the practice mentioned at Para 1(g) of this circular, whenever
price band of a scrip or futures contracts is flexed in one direction, the price
band on the other side would be flexed concurrently by equivalent amount in
the direction of price movement. Orders pending in the erstwhile price band and
the new price band, after sliding, would be cancelled by exchanges. This would
limit the dynamic price band as scrip price trends in one direction and in effect
limit the price volatility. This would also provide an opportunity to market
participants to place their orders nearer to the prevailing market price.
7. For instance, yesterday’s closing price was Rs. 100 and today’s lower band and
upper band were Rs. 90 and Rs. 110 respectively. If price trends upwards,
resulting in upper price band being flexed to Rs. 115 (after satisfying enhanced
conditions precedent), the lower band would shift upwards to Rs. 95 and orders
lying between Rs. 90 to Rs. 95 would be cancelled by exchange. It may be
noted that if the price subsequently trends downwards on the same day and
hits the new lower band i.e. Rs. 95, the same would be flexed downwards to
Rs. 90 after satisfying the aforesaid enhanced conditions.
8. Stock Exchanges would put in place necessary mechanism to intimate trading
members/clients regarding such cancelled orders.
(E) Trading in options segment during cooling off in underlying / futures
contracts
9. In modification of the practice mentioned at Para 1(e) of this circular, a
temporary price floor or ceiling for options in the sentimental direction of price
trend in the underlying, as applicable, would be placed in the options, once
underlying scrip triggers cooling off. This is summarised below:
a. If the Last Traded Price (LTP) of the options contract is available and not
stale, the temporary floor or ceiling as applicable, would be linked to LTP
of options contract.
b. If the LTP of the options contract is unavailable or stale, the temporary
floor or ceiling as applicable, would be linked to theoretical price of the
options contract.
c. Such temporary floor or ceiling would allow certain absolute rupee
movement or percentage movement over the last traded price/
theoretical price to allow market participants to, for instance,
hedge/close their open positions by executing trades in options during
cooling off.
d. Once price band for underlying scrip is flexed, at the end of cooling off
period, the price band for options contracts would be flexed concurrently,
thereby doing away with temporary floor or ceiling.
e. Stock Exchanges would put in place uniform formulation around the
above requirements.
10. The Stock Exchanges are directed to:
a. Prepare a comprehensive Standard Operating Procedure, within 45 days
from the date of the circular, to implement various operational issues
emanating from the circular and suitably intimate market participants
regarding the same in due course;
b. Take necessary steps to put in place requisite infrastructure and systems
for implementation of the circular, including necessary amendments to the
relevant bye-laws, rules and regulations;
c. Bring the provisions of this circular to the notice of their members and also
disseminate the same on their website; and
d. Communicate to SEBI, the status of implementation of the provisions of this
circular as per the stipulated timelines.
11. The circular would be implemented by Stock Exchanges in a phased manner.
Requirements mentioned at Para (A) of the circular would be effective from
June 03, 2024, those at Para (B) and (C) would be effective from August 19,
2024 and those at Para (D) and (E) would be effective from October 21, 2024
onwards.
12. The circular is being issued in exercise of powers conferred under Section 11
(1) of the Securities and Exchange Board of India Act, 1992, to protect the
interests of investors in securities and to promote the development of, and to
regulate the securities market.
