The Impact Of Sin Stock Exclusion On Portfolio Performance.

The Impact Of Sin Stock Exclusion On Portfolio Performance.

“‘As about 10% of the market can be classified as sin, this would imply an additional 0.10% return loss if sin stocks are excluded. Combined with the 0.27% estimated loss due to the adverse effect on factor exposures … this brings the total loss in expected return to 0.37% per annum.

Although this might seem small, a pension fund which generates 0.37% lower returns on its equity portfolio than peers may end up providing 5% lower pensions in the long run.’ That is not an insignificant loss.”

[COMMENTARY] This article reports on a study saying that excluding 11 particular industries in a portfolio results in a 0.37% annual loss in returns. I’m sure many will debate the methodology and conclusions of this study.
