One thing that irritates me the most is when Companies which are traded on both NSE and BSE report critical information to one Stock Exchange but not another.
Multi Commodity Exchange of India Ltd is traded on both NSE and BSE.
On BSE, the shareholding patterns of MCX are upto date as can be seen below:
However on NSE, the share holding patterns of MCX was last updated one year back on 30 June, 2017 !!
This is a clear violation of listing guidelines…sloppy on the part of NSE as well.
