Goldman Sachs has lowered its target price for BSE shares to Rs 4,880 from Rs 5,650, maintaining a "neutral" rating, citing potential impacts from upcoming regulatory changes affecting proprietary traders, who contribute nearly 70% of BSE's average daily turnover. Shares of BSE Ltd fell by 5.1% to Rs 4,395.7 following the announcement. Additionally, BSE faces legal scrutiny related to alleged irregularities in a 1994 listing permission, although SEBI has dismissed the complaint as "frivolous." Despite these challenges, BSE shares have risen approximately 92.87% over the past year.
