The risk is that Apple's plans for GT Advanced Technologies' sapphire is more limited, resulting in sales missing hyperbolic expectations. Due to its immensely speculative nature, potential investors in GT Advanced Technologies should keep their positions small -- no more than 1%-5% of a well-diversified portfolio.
it's already had a huge jump in price. It's still a speculative stock since neither apple or gtat can officially confirm their business relationship or apples intent on using gtat for apple products. There is as much risk for the downside as upside.
Lastly, apple has already probably made money off of their investment even without using gtat sapphire.
Lastly, rumors of a delay in apple production is NOT good for GTAT.
Everything will be clear in September. Until then we'll have just a bunch of rumors and cold/warm air from analysts. A sapphire screen for the new Iphones is guaranteed in my opinion. The only bad thing that I could think of would be a delay, but I don't believe they will be any, as the same rumors came up every year. Funny, how Apples stock went up on the delay rumors yesterday anyway.
My price target: back over 16.50 for this month with a range of around 15-19, at least 26 $ before this year is finished, >46 next year. Higher, if Samsung or other brands join the sapphire train. Then GTAT should have also full production running to satisfy the demand from other customers. Plus of course the solar business.
Lastly: everything looks good, we just need to be patient. In a year from now, GTAT's share price will be at least more than twice what it is today, with no limit to the upside.
