Three perspectives

Peter Lynch

Lynch varnade för Dunning-Kruger-effekten och menade att 'känslor är investerarens värsta fiende'. Han föreslog reglerbaserade strategier för att motverka att överskatta sin egen kompetens.

Benjamin Graham

Graham betonade 'margin of safety' just för att motverka effekter av Dunning-Kruger-effekten. Han menade att investerare måste ha marginaler för att hantera att överskatta sin egen kompetens när det uppstår.

AK1A's interpretation

AKM1 identifierar Dunning-Kruger-effekten som en riskfaktor i V09 (ROE-stabilitet) och V12 (intäktsstabilitet). Bolag vars investerare lider av att överskatta sin egen kompetens får högre riskpremie.
