To curb excessive volatility, stock exchange BSE today revised the circuit limit for share movement of nine companies, including Borosil Glass Works and Unitech International.
The new limits, effective tomorrow, will ensure stock prices do not go up or down beyond a level during a session.
In a circular, the exchange said it has set a circuit limit of 10 per cent for Borosil Glass Works.
Circuit filter mechanism is used by stock exchanges to keep excessive volatility for a scrip in check. It is the maximum fluctuation that is allowed in a stock, after which trading in it gets suspended if the permissible limit is hit in either direction.
A limit of 10 per cent has also been set for Dynamic Industries, Himalya International, STEL Holdings, PMC Fincorp, Max Alert Systems and Amrapali Capital and Finance Services.
The exchange has fixed a limit of 5 per cent for Unitech International and GKB Ophthalmics.
The circuit filters have been changed from their existing levels in the nine scrips with effect from October 4, as per the circular.
