Update To The Methodology Of BNC-BTSE Composite Index (BBCX)

The current real time pricing methodology involves the removal of maximum and minimum of midpoint prices for each market (‘trimming’) and subsequently calculating the average market price (‘mean’) for each underlying assets.

The updated pricing methodology will first apply a Price Anomaly Factor (PAF) to all midpoint prices based on the degree of deviation from the median price. The PAF is then used as a weighting factor in calculating the average market price for the underlying assets.

These changes will make BBCX tracks more closely to the real-time market performance of the underlying assets
and enhance its accuracy and robustness
