Bloomberg and Reuters have both added the IDNX domain price index, which uses Sedo market data, to their Web sites.
The IDNX has used real estate economic methodology to index more than 200,000 domain transactions since 2006 and, claims Sedo, shows strong correlation with broader economic indicators. This, shows "domains are as much an economic asset as real estate, stocks or shares" argues the company.
Thies Lindenthal, MIT researcher and IDNX creator, says: "It is gratifying to see people realize that domains are a valid investment option. Internet entrepreneurs and domain industry professionals have long recognized fluctuations in domain value that parallel the economy as a whole, but unlike most other markets, these changes were not being tracked."
The highest price ever paid for a domain is thought to be the financial services-related Insure.com, which sold for $16 million in 2009.
