Everyone Thought This Glass Would Be On Front Of The iPhone 6 - It's Not, And Now The Supplier's Stock Is Tanking

GT Advanced shares were down as much as 14% on Wednesday after falling about 12% on Tuesday following the announcement that Apple's iPhone 6 and iPhone 6 Plus would not feature a full sapphire display.

The display for Apple Watch, which is set to be released in early 2015, and the camera lens on the new iPhone are sapphire displays, but not the main front display, as had previously been hoped.

The steep drop in shares of GT Advanced, however, follows reports ahead of the iPhone announcement said that iPhone 6 wouldn't feature a sapphire display. Additionally, GT Advanced and Apple announced in November 2013 that the company and Apple signed a five-year sapphire materials agreement.

But it seems that investors were still holding out hope that Apple would surprise and announce a full sapphire display.

This is what the disappointment looks like, in chart form.
