为什么不是hybrid呢？

问题如下：

Angela Green, an investment manager at Horizon Investments, intends to hire anew investment analyst. After conducting initial interviews, Green has narrowed the pool to three candidates. She plans to conduct second interviews to further assess the candidates’ knowledge of industry and company analysis.

Prior to the second interviews, Green asks the candidates to analyze Chrome Network Systems, a company that manufactures internet networking products. Each candidate is provided Chrome’s financial information presented in Exhibit 1.

Green asks each candidate to forecast the 2020 income statement for Chrome and to outline the key assumptions used in their analysis. The job candidates are told to include Horizon’s economic outlook for 2020 in their analysis, which assumes nominal GDP growth of 3.6%, based on expectations of real GDP growth of 1.6% and inflation of 2.0%.

Green receives the models from each of the candidates and schedules second interviews. To prepare for the interviews, Green compiles a summary of the candidates’ key assumptions in Exhibit 2.

Based on Exhibit 2, the modeling approach used by Candidate B to project future net sales is most accurately classified as a:

选项：

A.hybrid approach. B.top-down approach. C.bottom-up approach.

解释：

B is correct. A top-down approach usually begins at the level of the overall economy. Candidate B assumes industry sales will grow at the same rate as nominal GDP but that Chrome will have a 2 percentage point decline in market share. Candidate B is not using any elements of a bottom-up approach; therefore, a hybrid approach is not being employed.
