PMs, base metals, bios, etc. It's weird, but everybody seems to have things that work for them and things that don't.
I'm mostly playing uranium, & PMs, with a dash of alt energy, and MJ stocks. Most of my uranium stocks have doubled since Dec - which is impressive since the price of the metal has barely moved. Fuel cell stocks have gone crazy - didn't play them as well as I could've. Started dabbling in MJ stocks when I finally became aware of their existence. Done real well, so playing them a little more.
My motto is: do more of what works & less of what doesn't - fundamentals be damned!
