On Thursday, December 19th, 2019, BNC will update its pricing sources for calculating the BNC-BTSE COMPOSITE INDEX (BBCX).
The current pricing sources are made up of five constituents exchanges and we will be introducing two more exchanges to make a total of seven exchanges. The expanded set of exchanges will make BBCX tracks more closely to the real-time market performance of the underlying assets and enhance its accuracy and robustness.
All constituents exchanges will be reviewed periodically by the BNC-BTSE index committee and updated in line with the overall market developments
