I guess you can throw KORS and DECK into the multitude of companies that sell shoes and purses and their stocks have doubled the last year. There's always competition, it show you deal with that makes you stand out from the rest.
I am in at the $57 level.You can protect yourself by writing covered calls. Nice premiums on CREE. I just recently started adding LED bulbs to my house. The risk reward is now attractive. Before you would spend 10 years worth of lightbulbs for a single Cree. Now it is down to 3 years which is good enough payback. The amount of shelf space at Home Depot is almost as large if not larger than traditional/CFL so although the chart looks bad, I think the future is very bright (no pun intended)
