问题如下:
Which of the following is wrong about Appraisal (smoothed) data
选项:
A.For certain assets without liquid public markets, like real estate, appraisal data are used in lieu of transaction data.
Appraised values tend to be less volatile than market-determined values.
measured correlations with other assets tend to be overstated.
解释:
C is correct
解释:
因为诸如房地产市场缺乏流动性,所以人们会用评估数据被用来代替交易数据。所以A选项本身说法是正确的,不入选。
因为评估数据往往具有平滑的作用,所以估价的价值往往比市场决定的价值波动较小。所以B选项说法本身是正确的,不入选。
评估数据与其他资产的衡量相关性往往被缩小了,而非夸大了。所以C选项本身说法错误,入选。
请问为什么用appraisal data时,标的资产与其他资产的衡量相关性会被缩小呢?
