India’s Closing Auction Turmoil Clouds BSE Growth Outlook
BSE introduced a new way to set share prices at the end of the trading day.
This system is called the Closing Auction Session.
It is designed to make prices fairer and reduce possible manipulation.
After it started on August 3, some options trading activity on BSE declined.
The exchange’s shares have also fallen by more than 9% this month.
Some analysts now worry that BSE may have less room to grow.
Jefferies and Nuvama both became more cautious about the stock.
India’s market regulator says the new system will stay.
BSE could try raising some fees to improve its profits.
BSE shares have fallen more than 9% this month amid concerns over the Closing Auction Session.
Options turnover and contract volumes declined after the system began on August 3.
Average daily premium turnover fell 18%, while contracts traded dropped 20% for two August expiries.
Jefferies downgraded BSE to underperform, while Nuvama cut its rating to hold and lowered its price target.
Securities and Exchange Board of India says the auction mechanism will remain despite complaints from market participants.

Investor and Analyst Concerns
Purpose of the auction

The Securities and Exchange Board of India supports retaining the mechanism, which is modeled on developed-market frameworks to improve price discovery and prevent manipulation.
Investor and Analyst Concerns
Analysts and investors are concerned that the new system has contributed to lower options turnover and volumes on BSE.
BSE’s growth outlook
Regulatory and Reform Case
BSE still has buy ratings from more than half of the analysts covering it, and the consensus price target suggests about 20% upside.
Investor and Analyst Concerns
Jefferies downgraded the stock to underperform, while Nuvama cut it to hold and reduced its price target by 20%; Nuvama said there was no near-term trigger.
Profitability response

BSE could raise options fees and messaging fees for its co-location facility to support profitability.
