How to do thorough research into a company to better understand whether to buy stock?
So, first -- good job on making a thorough checklist of things to look into. And onto your questions -- is this a worthwhile process? Even independent of specific investing goals, learning how to research is valuable. If you decided to forgo investing in stocks directly, and chose to only invest in index funds, the same type of research skills would be useful. (Not to mention that such discipline would come in handy in other fields as well.) What other 80/20 'low hanging fruit' knowledge have I missed? While it may not count as 'low hanging fruit', one thing that stands out to me is there's no mention of what competition a company has in its field. For example, a company may be doing well today, but you may see signs that it's consistently losing ground to its competition. While that alone may not dissuade you from investing, it may give you something to consider.  Is what I've got so far any good? or am I totally missing the point. Your cheat sheet seems pretty good to me. But a lot depends on what your goals are. If you're doing this solely for your education and experience, I would say you've done well. If you're looking to invest in a company that is involved in a field you're passionate about, you're on the right track. But you should probably consider expanding your cheat sheet to include things that are not 'low hanging fruit' but still matter to you.  However, I'd echo the comments that have already been made and suggest that if this is for retirement investments, take the skills you've developed in creating your cheat sheet and apply that work towards finding a set of index funds that meet your criteria.  Otherwise happy hunting!
