Can LEDs Brighten Investor Portfolios?

Goldman Sachs recently highlighted LED lighting as a top “disruptive” theme over the next decade. While I'm often inclined to believe that these sell-side "theme pieces" are designed more towards generating attention during stretches of slow company news, I have little doubt that the penetration rate of LEDs in the lighting market is going to increase significantly over the next decade. That is going to fuel significant demand for LED-making equipment, LED packaging, and finished lighting fixtures for companies like Aixtron, Cree, Philips and Osram What is less clear to me is the extent to which investors can expect to see huge gains at this point – the “LED revolution” has been long in coming and while there are certainly going to be trading opportunities come and go, the idea of “buy and hold” in this sector seems optimistic at best.
