Investment Check List

I mean mine isn't as much an "investment checklist" as it is trading rules that I follow. I mean I generally have one that is like

1. Why this position. What is the rationale for it.
2. What is my risk reward ratio
3. What is the catalyst for the position i'm looking at.
4. What is my timeframe on the trade (i.e.. day, week, month etc.)
5. Make sure the position is of proper size relative to my portfolio (this is different than my risk/reward calculation)
6. Bounce it off multiple people/ make sure I'm not missing something.
7. Establish entry and exit points.
8. Run everything again. Twice. (The only exception I make here is if it is a quick day trade, as chances are If I do more than a quick look over and some quesstimation I've missed my entry point.

That might not be particularly enlightening or uncommon but It is just a basic framework for some trades I do. I try to follow that closely no matter what the trade (with some variations depending on the instrument/oppurtunity) mainly because I think that discipline and process is key with trading (another thing that took me awhile to learn as In real life I don't plan anything).

Sorry, I realized after I posted this that you were looking for an analysis checklist, but I think some of the things I mentioned still apply.
