Everyone has their own risk tolerance. It is one thing to be overweight a single sector, another to be overweight a specific country, and an entirely more risky proposition to be overweight a single company.Getting back to your point about concentration risk though, I struggle with this myself, as my employer is one of the companies on that list, and I've been buying via the employee stock purchase plan for close to a decade now. This one stock is now taking up 20% of my portfolio, but the milk of the dividend teat has so good I've been loathe to sell, despite knowing better about portfolio concentration risk.

That being said I am always open to new approaches and learning new strategies for investing. I recently started looking at adding some REIT concentration with this Emaxis Developed REIT fund. No domestic REITs though.
