The article explores whether real estate investment trusts (REITs) that focus on domestic investments perform better than those that invest globally. The researchers studied a variety of geographically diversified REITs and found that some countries show a strong preference for investing at home. Surprisingly, having a concentrated portfolio in one's home country doesn't always lead to higher returns or more consistent profits. This suggests that diversifying investments across different countries may be a more effective strategy for REIT asset managers.
