作文: Cellophone这个公司的annual report里这么讲: cell phone manufacturing需要用到很多expensive metal materials, 例如金银铜铁。过去几年的evidence中可以看到,这些expensive metal materials的price rises and falls dramatically. Cellophone自己forecast说将来cell phone division 生产量会很大,也会大量购买这些metal materials。Cellophone现在要lock in large quantities of metal materials来purchase,以此lock in cost。这样的话,cellophone在将来就能实现lock in savings and guarantee continued high profits.
这arguement 靠谱么?
