This paper will assess the relationship between tenant characteristics and public REIT volatility. Specifically, we focus on the retail REIT subset of the industry. Given that retail REITs are one the most transparent asset classes, they provide an interesting landscape for evaluating the relationship between the firm and the customers, or in this case, the tenants. Specifically, we assess how major tenant ownership, public or private equity owned, impacts the volatility of the REIT’s stock price using 2010 data on 30 retail REITs. Controlling for tenant credit quality, leverage, ROE, book-to-market, size, age, region and property focus, we find that a higher percentage of rental revenue from private equity owned tenants is associated with lower REIT stock volatility, and a higher percentage of rental revenue from publicly owned tenants is associated with higher REIT stock volatility.
