During the 70s and into the 80s I invested in penney stocks and stocks of which the broker makes a market. I was satisfied with he degree of my success, but it required much more of my attention than I was eventually willing to exert.
"Generosity. That was my first mistake." "Experience must be our only guide; reason may mislead us." "Instagram is Twitter for people who can't read."
I favor sound investing for my portfolio, but I do set aside a little bit for speculative stocks. Over the holidays, I bought a legalized marijuana penny stock. I made a 60% gain, so I was pretty happy. But from everything I read, penny stocks are extremely risky.
