Rare Earth, Bull-Bear Score: 2

China's comprehensive restrictions on rare earth metal exports have led to a sharp reduction in global supply.

1. Settlement price for a specified date

2. Average settlement price for a specified period

Pricing formula: Settlement price = Business Community Benchmark Price × K + C

K: Adjustment coefficient, including factors such as account period cost.
