The line graph illustrates the monthly percentage fluctuations in the prices of copper, nickel, and zinc throughout 2014. Overall, all three metals exhibited volatility, with nickel showing the most extreme price swings, while copper remained relatively stable.
Nickel started the year as the highest-performing metal, peaking at 6% growth in January. However, its price plummeted thereafter, reaching a trough of -3% in June—a sharp 9% decline from its January peak. After June, nickel prices stabilized, ending the year with a modest 1% increase.
Zinc displayed a more erratic pattern. It began at 1% in January, rose to 3% in March, then fluctuated between -1% and 2% until October. Notably, zinc experienced the steepest monthly drop (-2% in October) before rebounding to 2% growth by December, finishing as the top performer.
Copper maintained the smallest price variations. It started at 2% in January, gradually declined to -1% in June, and then hovered around 1% for the rest of the year. By December, copper’s price change stood at 1.5%, slightly below zinc but above nickel.
In summary, nickel’s volatility contrasted with copper’s stability, while zinc showed late-year resilience to become the best-performing metal.

该折线图展示了2014年全年铜、镍、锌三种金属价格的月度百分比波动。总体而言，所有金属价格均呈现波动性，其中镍的价格波动最为剧烈，而铜则相对稳定。
镍以全年最高涨幅（1月6%）开局，但随后价格暴跌，6月跌至-3%，较1月峰值骤降9%。6月后，镍价趋于稳定，年末微涨1%。
锌的价格走势更为不稳定。1月起步为1%，3月升至3%，随后在-1%至2%区间波动至10月。值得注意的是，锌在10月出现最大单月跌幅（-2%），但年末反弹至2%，成为全年表现最佳的金属。
铜的价格波动最小。1月为2%，6月逐渐降至-1%，下半年稳定在1%左右。12月铜价涨幅为1.5%，略低于锌但高于镍。
综上，镍的剧烈波动与铜的稳定性形成对比，而锌在年末展现出强劲反弹，成为全年表现最优的金属。

The line graph depicts the monthly percentage changes in the prices of copper, nickel, and zinc throughout 2014. Overall, all three metals exhibited volatility, with nickel showing the most extreme swings and copper remaining relatively stable.
Nickel started the year as the top performer, peaking at 6% growth in January. However, its price plummeted by 9 percentage points over the next five months, hitting a trough of -3% in June. After this sharp decline, nickel stabilised, ending the year with a modest 1% increase.
Zinc displayed a more erratic pattern. It began at 1% in January, rose to 3% in March, then fluctuated between -1% and 2% until October. Notably, zinc experienced the steepest monthly drop (-2% in October) before staging a strong rebound to 2% by December, emerging as the best-performing metal.
Copper maintained the smallest price variations. Starting at 2% in January, it gradually declined to -1% in June, then hovered around 1% for the rest of the year. By December, copper’s price change stood at 1.5%, slightly below zinc but above nickel.
In summary, while nickel’s volatility contrasted with copper’s stability, zinc demonstrated late-year resilience to become the top performer.
