I do some derivative trading but I tend to watch stocks on things like Motley Fool and invest where I feel comfortable. Actually edit: I probably just invest where I'm comfortable more often than derivative now that I think more about it. Like I said, I tend to watch Motley Fool closely, they have given me GREAT advice time and time again and I even took risks they said MIGHT work out that have. I currently own stocks in TSLA, PRMW, TSN, KEYS, WMT, among others. I don't feel like listing EVERYTHING out.
I also enjoy using Robinhood, it's a nice app
