Two offers of $4.00 per dmtu, which were reported by buyers, and one trade of medium-sized volume at $4.22 per dmtu were included in the rationale as data points used to calculate Fastmarkets’ weekly manganese ore index 37% Mn, cif Tianjin.
But they had been automatically discarded as outliers, in accordance with Fastmarkets’ methodology. All data points that fall more than 10% away from the initial calculated index are automatically excluded – the index is then recalculated.
Fastmarkets’ rationale database has been updated to reflect this change. There is no change to the index number, however, which was published correctly at $3.50 per dmtu on October 25.
