I'm not a trader but if I was, this article would be an excellent example of how not to do it https://www.wsj.com/articles/robinh...e-that-got-away-11619099755?mod=hp_listb_pos3 Points to learn for both traders and investors. - these guys played with money they couldn't afford to lose. They had kids to raise and feed and they put they family's livelihood at risk. - they borrowed via margin in an attempt to get rich quick without knowing the potential pitfalls. This is so dumb to me. When you take a mortgage out or a car loan, you presumably read at least the key parts of the loan doc before signing, including what happens if you don't make a scheduled payment! These guys were idiots for buying via margin and not understanding what that exactly entailed. - Both traders and investors have to exercise some sense of self discipline and this begins with knowing thyself and with being realistic in expectations. These guys had no self discipline. They were thinking of buying expensive cars within a short time of starting out. Foolish! - Everybody makes bad trades or bad investments. Every trader has at least one moment of kicking oneself for a poorly timed trade. Every investor thinks at least once "What the hell was I thinking." The fools in the article thought they would nail it every time. Thoughts?
