Re TG's description today of the smart phone opportunity, one might consider shorting Corning because it seems that sapphire WILL replace Gorilla Glass at the high end. There just doesn't seem to be any downside for the phone makers to replace it with sapphire, including cost, thanks to GTAT's processes. link to the Cannacord Presentation. Also, if they move sapphire to tablets, the producers will have to move to six-inch boules in much greater volume, which should greatly increase demand as well. The smartphone opportunity puts GTAT solidly into the growth company category, and we could easily see correspondingly high earnings multiples soon--which means the stock could triple in price in the near term.
