Do most of you actually write out stock analyses or just scan metrics and go?

Lately I've been wondering how many people here actually write down their thoughts when analyzing a stock.

Do you go as far as outlining your investment thesis, risks, catalysts, etc. Or do you mostly just look up a few key metrics (P/E, revenue growth, margins, etc) and make a decision on the fly?

If you actually write your analysis, what do you use? Pure docs + screenshots of charts, sheets of data, links, etc, or somenthing else?
