步骤2：分别估算每种业务的风险（beta）。这里的beta成为资产（asset）beta或无杠杆（unlevered）beta。步骤3：将上一步获得的无杠杆beta进行加权平均，权值是根据某业务的价值（value）对比所有业务的价值加总来确定的。步骤4：根据目标公司的财务杠杆（debt to equity 比值）计算最终的beta。选择可类比的...
One predictive regression of monthly momentum returns on its bottom-up beta produces an OOS R-square of 2.41%. This contrasts with the usual negative OOS R-squares of similar predictive regressions for the market excess return.doi:10.2139/ssrn.2144204Pedro Barroso...

A bottom-up label-free proteomic mass spectrometric analysis of the human embryo secretome is described. This approach seems to allow quantification and identification of unique proteins related to positive- and negative-implantation groups, which can be further validated as biomarkers for selection and...
