The primary sources of data are those which provide direct information; the secondary sources of data are the sources which already contain the primary sources and act as intermediate source for end user. Jim and Tony used company reports from RNS (Stock Exchange Regulatory News Service) based on London Stock Exchange filings and provided by company news service from the London Stock Exchange; so RNS was the secondary source. They retrieved company filing to do their research on the basis of their hypothesis; hence the company reports (both prelims and full annual reports) are the primary sources of data.
