Capital markets regulator Sebi on Sunday came out with a proposal to strengthen the existing price band formulation for scrips in the derivatives segment to deepen volatility management and minimize information asymmetry in the market. Price bands for scrip or a derivative contract represent the boundaries within which the competing orders of buyers and sellers are accepted for the day by the trading system of the stock exchange. For scrips having derivative contracts on them, these price bands are dynamic and can be flexed depending on trading during the day.
In its consultation paper, Sebi has proposed that in case a share in the futures and options segment falls or rises beyond 20 per cent a day, cooling off period should be increased in a phased manner, subject to a maximum cooling-off period of one hour from the current 15 minutes at present. After this, such scrip should be permitted to move only a further up to 2 per cent as against the current limit of 5 per cent. The proposals would provide a tool to control extreme market volatility and aid in containing worst-case single-day price movement in the scrip, Sebi said.
In addition, Sebi has proposed placing daily hard limits on the scrips in the futures contracts and corresponding price limits in options contracts in view of the surveillance-related findings of exchange. It suggested that a price band of say 10 percent should be provided at the start of the day for the scrip and futures contracts. However, these price bands would remain as hard limits for the day over the period determined by the exchange.
Accordingly, for such a period, there would be a daily hard band of say 10 per cent which would not be capable of flexing intraday. In addition, Sebi suggested that existing preconditions of a minimum number of 25 trades from five different unique client codes ( UCCs) on both sides may be increased, but keeping in mind that too high a value may impede the price discovery process.Further, additional conditions of a minimum number of trading members on both sides of the trades at or above 9.9 may be added, say 3 to 5 trading members on both sides.
