The BSE and NSE have put a price band of 10 per cent on share movements of four companies Essar Oil,Suzlon Energy,Educomp and CORE Education as part of preventive surveillance measures.
The price band will be applicable for trading in the four stocks with effect from April 2. The decision to limit any upward or downward movement in their share prices to a maximum of 10 per cent has been taken by the stock exchanges in consultation with market regulator Sebi. To prevent any systemic risks arising out of erroneous trades or stock manipulations,Sebi late last year asked the exchanges to put in place a system for dynamic price bands.
