Le plus grand risque pour une stratégie d'investissment (ou pour n'importe quelle stratégie probablement): laisser les autres faire des choix à notre place.
Une comparaison intéressante entre l'approche de Warren Buffet et celle de Ken Lewis.
My observation is that independent thought is extremely rare, which makes it very valuable. On the other hand, outsourced thinking appears to be pervasive in the investment community, and because of how we're wired, the dynamic is unlikely to change. Regardless of how convincing the facts are, we are just more comfortable if we can mold our opinion around the opinion of others.
