The graph illustrates the average monthly percentage change in the prices of copper, nickel, and zinc throughout 2014.
Overall, all three metals experienced fluctuations during the year, with nickel showing the highest volatility, while copper and zinc remained comparatively stable.
In January, nickel prices began to rise sharply, peaking at around a 6% increase in February. This was followed by a steep decline, reaching approximately −3% in May. Over the following months, prices recovered to moderate levels and rose again towards December.
Changes in copper and zinc were far less pronounced. Copper prices stayed within a range of about −1% to 2% for most of the year, with minor dips in June and September, followed by modest growth at the end of the year. Zinc prices hovered close to zero change, showing only a slight upward trend in the final quarter.
In summary, while nickel underwent significant price swings in 2014, copper and zinc demonstrated a far more stable pattern.
