Has there been any talk of Stockopedia giving paid subscribers access to 10 years of financials in the StockReport? Morningstar, GuruFocus, CapitalIQ, and Reuters all do this. You need at least 10 years to get a good picture of how a given company's stock behaves in a downturn or in a financial event.
We can go back about 5 years by using the Print button on each stock report and accounts page to see a pdf of what that page looked like in previous months.
