However, in the following years, the price gradually decreased from 6% to 1% in three months. The price then showed steady decline until June, where it dropped to its lowest. There were fluctuations in the cost throughout the remaining months, and finally reaching to 1% where it showed steady-pace.
In contract, Copper and Zinc started with 2% and 1% respectively. The percentage for Zinc showed sudden spike in cost changes and rose to 3%, where it reached its peak. On the other hand, Copper price difference showed consistent downward trend until it reached to its lowest in May, while Zinc, after several decline reached to the bottom of its scale.
