I use a portfolio based strategy (by which I mean I look at a group of related securities in order to give my analysis context, rather than look at one stock at a time) and I use analysis metrics that are appropriate for the group. The metrics can range from financial statement analysis, to statistical analysis, to qualitative reviews. Sometimes I experiment with new methods, but I will disclose that. This framework keeps me objective and helps me find the best and worst of a group . Sometimes it leads to an inconclusive result if stocks are doing well by some measures and poorly by others. I follow up on a periodic basis on the recommendations I make and I will usually invest my own money after I submit an article for publication.
