The security characteristic line's slope is asset's excess return. The security characteristic line's slope is asset's risk premium. A is correct. The security characteristic line is a plot of the excess return of the security on the excess return of the market. The slope of Sis the asset's beta.请问sml的slope为什么不是market risk premium， 记得老师在课上提到market risk premium对于全部asset都是一样的， 而不一样的是每一个资产对应市场的bet然而在这直线上每一点算出来的斜度不都一样，所以不应该是risk premium吗
