This graph illustrates the average monthly change in prices during 2014 for three different metals: copper, nickel, and zinc. While the numbers fluctuated, by the end of the survey period, these three metals exhibited similar trends.
At the onset of the data, copper experienced the most significant price change, with a rapid climb of 6% compared to the previous month. However, this surge was short-lived. Over the next five months, copper faced a bleak period, with a sharp total drop of 9%, plummeting from 6% to -3%. After several months of struggle, copper saw a resurgence in the latter half of the year, with a slight increase to 1%.
Similarly, the price changes for nickel and zinc remained relatively stable throughout the year, fluctuating between 3% and -1%. It is noteworthy that the percentage changes for all three metals were almost indistinguishable in the last month.
