The line graph illustrates the percentage change in the prices of copper, nickel, and zinc in 2014.
Overall, the prices of nickel and zinc experienced notable fluctuations during two periods: from May to July and from September to November. Nickel had the highest price in January, while zinc had the lowest; these positions swapped over the period. Copper retained its second position with minor fluctuations.
The prices of nickel and zinc showed significant fluctuations in two notable periods. In January, nickel held the highest price at 6%, but it sharply decreased to 1% by May. After April, the prices of nickel fell into negative percentages, with a sudden drop from May to June, reaching -3%, marking the lowest price over the period. Despite a notable rise from -2% to 1% from October to November, nickel ended the year with the lowest prices in December. Conversely, the prices of zinc peaked from 1% to 3% between January and February, fluctuating throughout the year. By October, zinc prices had increased by around 2%, securing the highest price percentage in December.
