后早期的回归模型,研究人员布鲁姆,朋友和詹森利用分组的方法来解决β测量问题。投资组合的回报和贝塔在通常是计算加权平均(布鲁姆,1970;朋友和布鲁姆,1970;詹森et al .,1972)。实证调查的分组方法称为收缩导致的问题。减少分组的收缩问题,研究人员建议形成组合使用命令β估计。这成为一个标准。贡献的实证测试黑色,詹森和斯科尔斯,做出以下的贡献。为了测试CPM,在场的回归模型,市场投资组合必须被指定。在规范的市场投资组合的情况下,可能有很多的病例。只有大约三分之一的市场投资组合是企业所拥有的时间。

公司资产被认为在股票和资金也有混乱的无形资产评估必须考虑。也考虑到国际市场的问题。测量误差中β股的分组组合是一个需要一个(哈洛& Rao,1989;詹森等,1972)。测量误差的问题可以通过观察来解决他们多元化的投资组合。而不是聚合确保风险投资组合分类基于特征元素更好的解释(詹森et al .,1972)。对市场β的计算,有必要从过去五年包括数据。过去五年的数据指出如何估算市场β。10组合的公司整理和组合的性能评估在t + 1模式年复一年的声誉。

After the early regression model, researchers Blume, Friend and Jensen made use of a grouping approach to solve the beta measurement problem. The returns and betas in the case of portfolios are usually calculated as weighted averages (Blume, 1970; Friend and Blume, 1970; Jensen et al., 1972). The grouping approach in empirical investigation led to an issue called as shrinkage. To reduce the shrinkage issues in grouping, researcher suggested formation of portfolios using ordered beta estimates instead. This became a standard later. The contributions to empirical testing as presented by Black, Jensen, and Scholes make the following contributions. To test the CPM, the regression models present that the market portfolio must be specified. Now in the case of specification of the market portfolio, there could be many cases. Only about a third of the market portfolio was owned by the corporate sector about the time.

Corporate assets were seen to be financed in equity and there was also the confusion of how intangible assets must be considered in this assessment. International markets issues were also considered here. In the measurement error in β the grouping of stocks as portfolios was a needed one (Harlow & Rao, 1989; Jensen et al, 1972). The measurement error problem could be addressed by looking at them as diversified portfolios. Instead of being aggregated portfolios were classified based on characteristics ensuring that the risk element is explained better (Jensen et al., 1972). For the market beta calculations, it was necessary to include data from the past five years. The past five years of data was to point out how to estimate the market beta. 10 portfolios of firms were sorted out and the performance of portfolios was assessed year after year in a t+1 pattern of reputation.
