I'm looking along the lines for IPO's that took off in the tech revolution, took a hit but are worth reinvesting in. Bionics, lean-manufacturing, bio/nuclear-medical, brain-wave research, &c. The super-genuis sold their stakes and tickers have changed since so I was wondering if others here had the same idea and if not if you'ld take a week or so and make this into a thread we could build on.
