Growth investors like to talk about inventions and new ideas. The pull of growth investing is all you have to do is find a great company with a great product that will soon be big and you can just buy the stock and sit back for incredible gains. There are several problems with this thesis.
American Technology Company [[atco]] was the first stock that ever interested me. I was into high-fidelity music at the time and it was in an industry magazine that I first read about its technology to use multiple point sources of sound waves to project sound to a specific location (rather than all around).
If I had invested in ATCO 11 years ago and held until today, I would have lost over half my money.
Disclosure: No position in ATCO.
