Canslim style, You only learn thru experience(15 years). Mkt is like poker/chess. Know the hand your dealt and manage risk accordingly. I use ST to talk to myself and journal. Id like to also help along the way if you can follow my nonsense! :)
I recommend individual investments and collections of investments, which are known as portfolios along with Evaluation of current and historical data to gain better insight into the company’s prospects.
