Data, Data, Data. Who owns it?
- Price is determined by demand and supply in a market but even if you crash or sky-rocket the price of some equity you don't really own that historical data but who does it own then? Do companies in some exchange own the data of their valuations or do the exchange own the data? It would sound odd that if Demand parties, such as individual speculators, don't own the data why would Supply parties, such as corps, own the data?
- Or does a programmer own the data if s/he records the data and visualize it in some artistic way?
- If I am given a random piece of historical valuation data, how can I be sure that it is free to use?
- So who owns data if it is determined by free market?
- Can I record equity valuations and get the right to use the data?
- Who owns the data if it is determined by starting/closing valuations of the day like with some index funds?
- Which party has a right over data in an open market?
- By which way you can get access to data like Schiller here? Can I offer data in a similar way over internet if I record it?
