Who owns historical valuations about equity such as stocks and index funds?
I expect that data may be copyright. Data that's published (e.g. on a newsfeed or web site) is subject to terms of use. Standard & Poor's web site says, about the Shiller indexes, Who do I contact at S&P to license my   use of these indices?   Questions   regarding licensing the   S&P/Case-Shiller Home Price Indices   can be addressed to:  Bo Chung    Managing Director    bo_chung@standardandpoors.com,   +1.212.438.3519 As for 'recording' the information yourself, that may depend on how and where (e.g. from what source) you're recording it. If for example you tried to record prices from the Canadian MLS (Realtor's) network, they too have their own terms of use on the data they publish. Copyright laws vary from country to country (and terms of use certainly vary): for example see http://en.wikipedia.org/wiki/Feist_v._Rural which is case law about copyrighting a phone directory in the USA, and contrast that with http://en.wikipedia.org/wiki/Database_right which is European legislation. So who owns data if it is determined by free market? I guess that "determined by free market" means that buyers and sellers are publishing their offers-to-buy and their offers-to-sell, and I guess that the publisher (e.g. the stock exchange) has 'terms of use' about the data (the offers) that they're publishing.
