In the annual report of a cell phonemanufacturing company to its stakeholders, its CEO says:

Cell phone manufacturing requires a large quantityof precious and expensive metals. In the recent decade, we found that the price of these metals rises and drops dramatically. In the forecast of the growth ofour cell phone division, high-volume purchasing seems to be highly-likely. If we purchase a large quantity of those metals today, we could lock our costs. Bydoing so, we can save money and guarantee a high-level profit.

攻击点(现编的，考试用了1235)：

(1)   High cost of precious metal storage is totally ignored by the company.

(2)   Price fluctuation has two directions. It is possible that the price of those precious metals drop dramatically in the future.

(3)   The forecast is made by the company itself. So we have strong reasons to question that the conductor may have vested interest and therefore inclined to manipulate the result of the forecast due to it will definitely influences the confidence level of investors.

(4)   The initial cost of purchasing precious metals will be significant. We have better choices like options/futures to provide the same function with less initial/storage cost and also less risk.

(5)   Even we have our cost of precious metals locked, we cannot made hasty generalization that our profit would be high, since there is not always a “ceteris paribus” situation in thereal life.

(6)   Before knowing the percentage of total cost that contributed by precious metals, we cannot judge the effectiveness of the plan.

(7)   We don’t know anything about the forecast. Since the model and parameters would be important for us to determinethe reliability of the argument, the inadequacy and partiality in the nature of evidence provided by the author to justify the conclusion would made those assumptions dubious.
