thats true; i have yet to see structured financial data for cheap. although depending on the targeted audience, that 'structure' varies. equity analysts might be concerned about operational performance, top line growth, margins, and stock buyback programs. debt/credit analysts might be concerned about cash flows, revolver draws, commercial paper programs, etc. there are many niche markets and existing services out there may have already provided these structures (albeit not cheaply and they may be proprietary if at a firm).

building a retail brokerage firm around structured market information i think is harder than it sounds. unless the transaction costs for each trade reflect the value-add of having a 'free' service structure financial data. currently, transaction costs reflect the quality of investment reports prepared by (usually) CFA investment professionals. i'm not sure if the free structured investment information would yield a transaction fee material enough to warrant a sustainable business model.
