Impact Assessment

This is a routine surveillance action by BSE’s DOSS department. The tightening of price bands (e.g., to 1% or 2%) for certain scrips such as Hindusthan Insulators & Industries Ltd and Aksh Optifibre Ltd suggests heightened scrutiny or unusual price movement concerns. Scrips moved to 20% bands (HRS Aluglaze, Mehul Telecom, Omnitech Engineering, Vivid Mercantile) may be experiencing relaxation of prior restrictions. Traders holding positions in these 26 securities should review order strategies to avoid rejections under the new band limits effective May 11.
