Not like AC/DC, Godsmack, or Megadeath. No, I'm talking about something way crazier.
I bought stock in these companies:
POSCO (NYSE: PKX), a Korean steel maker, and Liquidmetal Technologies (OTC:LQMT), a company (co-founded by a Caltech prof) that produces a new class of amorphous alloys that are stronger than titanium.
Check out the company websites. I must be totally nutto. :-)
