I am not by any means a "day trader" or "stock aficionado" or anything of the sort. My wife and I dabble in trading, and are trying to learn the stock market. I've made some money off of stocks, but only in industries I know or pay attention to. For example, I am a Tesla fan. I own a Tesla Model S, and it's one of my most prized possessions. I pay close attention to the company and what they are releasing/doing. Because I pay so much attention to all aspects of the company, I also have stocks in Tesla and I monitor how they are doing.
