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.
Find undervalued stocks and accumulate. Diversify. Don't gamble on junk. Buy on trend--there are always dips, esp on Fridays and options weeks. Watch ends of quarters. Be patient, use settled cash so you can bail fast. Have a plan and stick with it.
