ResearchTeam Methodology

ResearchTeam is the consolidation of coverage from each research provider on the team, where a minimum of three providers must haverecommendations for a company for ResearchTeam to issue a rating. If a minimum of three research providers do not have a rating for acompany,then the team rating for the stock is “Not Rated”. All of the research providers must have unanimous Buy ratings for ResearchTeam to

issue an ‘Accumulate’ rating. It takes only one opinion to make any other rating. A single ‘Sell’ rating will make the team rating for that stock a‘Reduce’.
