Domain investors acquire domain portfolios with the goal of selling them at an attractive ROI. Given that most end users are not willing to pay premium prices for a domain name and supply greatly exceeds demand, industry portfolio turnover tends to be around 1%. Thus, a 300-domain portfolio over eight years might result in 25 sales. Most domains that are worth renewing for eight years are generally not acquired for $10. They are normally acquired via research plus backorder or a domain auction or via aftermarket purchases. So after renewing nearly 300 domains for eight years, the investor has a considerable sum invested in their remaining portfolio. Could portfolio returns be enhanced via development? How does the risk / reward of development compare to domain acquisition and resale?
