Who are the major suppliers of index data that cover multiple index providers, e.g. MSCI, FTSE, S&P etc?
There are a huge number of people sourcing e.g. equity data, but index data is much harder to come by.
I am only looking for very high level information and at low frequency - the EOD number for each index would almost be enough.
Basic information on the constituents and their weights would also be useful, but in depth analysis and such like of the indexes and their constituents isn't required.
Sites like Yahoo Finance just seem to cover a small number of major indexes, whereas I'm interested in sector indexes and such like that aren't commonly covered, e.g. MSCI World Telecommunication Services.
I am looking for a provider with historical data (going back e.g. 10 years) who will also provide data day-by-day going forward.
Currently I work with a data aggregator who, before they supply particular data, requires us to negotiate agreements directly with the individual index providers, e.g. MSCI or FTSE, rather than handling this on our behalf.
They also provide the data in a highly non-standardized form, e.g. data from MSCI will come in a different form to that from FTSE.
And they only sell the data in very non-flexible bundles, e.g. rather than just buying basic EOD numbers one has to buy a hugely expensive package of in-depth analysis of which these numbers are a tiny part.
It's not that I don't expect to pay for this data - but it would be nicer if possible to pay for just the basic data needed and to have the negotiation with the actual index providers handled behind the scenes by the data provider themselves.
Apologies if you feel this, as a rather commercial question rather than something interesting on e.g. option pricing, isn't directly appropriate to this stack exchange.
