Volatility in share prices have come down significantly following the introduction of additional periodic price bands for securities 'exclusively' listed on BSE platform.
The exchange, in October, had introduced weekly, monthly, quarterly and yearly based price band framework for the securities exclusively listed on its platform to prevent excessive volatility in the shares.
Earlier, BSE had a daily price band mechanism -- maximum permissible limit, within which the share price can move in a day. The listed-securities are assigned a daily price band of either 20 per cent, 10 per cent, 5 per cent or 2 per cent based on the pre-decided joint criteria.

In case of a price variation greater than or equal to 25 per cent, 367 securities were there in the first half of the current fiscal as against 290 in October.
Further, the number of surveillance actions against securities have also fallen during the period under review.
This long duration price band framework, which is in addition to the daily price band mechanism, apply to stocks "exclusively" listed and traded on BSE equity trading platform including SME and SME ITP platform.
Under the new framework, a security having daily price band of 20 per cent can move upward or downward up to 60 per cent in a week. Whereas, in a month it can move upward or downward up to 100 per cent. It can move 200 per cent or 400 per cent on a quarterly and yearly-basis, respectively.
Similarly, security with a daily price band of 10 per cent can move 30 per cent on a weekly-basis, 60 per cent on monthly-basis, 100 per cent on quarterly-basis and 200 per cent in a year.
A stock assigned a daily price band of 5 per cent would be allowed a 20 per cent (weekly), 30 per cent (monthly), 60 per cent (quarterly) and 100 per cent (annually) movement.
Those with 2 per cent band will have 10 per cent band for the week, 20 per cent for the month, 30 per cent on quarterly basis and 50 per cent movement annually.
