I study the Shareholding Patterns very closely for my Investor Wisdom Newsletter.
So you keep finding instances where some details are reported to BSE and not to NSE and vice-versa.
Take for instance, Balaji Telefilms shareholding pattern filing for BSE.
Reliance Industries and AADI are prominent investors in the Company…collectively owning more than 28% of the Company.
This key information is missing from their NSE Exchange Filings.
