I work in biotech so I invest in biotech. I try to play runups into results. I hold often through results because of major DD. I like small mcap companies and binary events. I mostly try to get in early and hold LT.
I'm new, but learning something everyday.
I like bios/ tech, but they must have fundamentals.

P.P.S Use stops.
