Smart vs Good: It's said the "idea" is just 10% of the trade. Position-sizing and risk-management are the other 90% Lots of very very smart folks invest in stocks. They do deep-dives into filings, talk to management, and google industry-wide trends. But that shit rarely matters. Here's a simple method that I know works: 1. Get long on meaningful breakouts. Sell some into run-ups to lower basis & de-risk. 2. If its going down, cut your losses. We used to say, "I'd rather be lucky than good", but GOOD often beats SMART. Commit to being a GOOD investor! make money when its available, and always cut losses.
