Because the influence is low to shear the factor that shearwall anti-shear strength more, and each factor returns the interaction 由于影響低矮剪力墻抗剪強度的因素較多,且各因素之間還相互作用。
Once you have an estimate of the factor sensitivities, it is a simple matter to multiply each of them by the expected factor return and add up the results 一旦你有了對因素敏感性的估算,將其一一乘上期望因素回報率并把結(jié)果相加就是一件簡單的事情。
(3 ) for time-varying risk premium and industrial momentum, serial autocorrelation of factor returns including size, be / me, and industry contributes mostly to momentum profits, especially industry momentum (3)時變風險溢價與行業(yè)慣性方面:公司規(guī)模、凈值市值比以及行業(yè)等因子的序列自相關(guān)性是慣性策略獲利性之主要驅(qū)動因素,尤以行業(yè)慣性顯著。
