Tech Five: Anticipation around Apple and carriers, too

Apple remains top of mind in technology news. Here's a look at five tech stocks to watch Thursday:

Apple. Invitations to an Oct. 16 event in Cupertino, Calif., went out to media on Wednesday and speculation is that a new iPad and new iMac computer will be unveiled. But a report from The Wall Street Journal suggests that demand for new iPhones could delay the launch of a new larger iPad until next year.

And this morning, activist investor Carl Icahn called on Apple to repurchase even more of its shares before the market catches up.

Apple shares are undervalued by half, Icahn said in a letter to Apple CEO Tim Cook. Icahn is one of the company's largest investors.

Apple shares, which closed at $100.80 on Wednesday, should be worth $203 based on projected earnings, Icahn said. Shares rose more than 1% upon the market's opening Thursday.

GT Advanced Technologies. Apple said on Wednesday that it would try to work with the company, which filed for bankruptcy Monday in the wake of losing the bid to provide tough "sapphire" display for the new iPhones. A bankruptcy hearing happens today. After having plummeted 92% to 92 cents a share earlier in the week, stock rebounded slightly then fell 9% Wednesday. Shares rose 11.8% to $1.23 in early trading Thursday.

AT&T. On the same day that it announced a settlement with the federal and state authorities to pay $105 million for "cramming" consumer cell phone bills with unauthorized charges, the company announced that it will pay a 46-cent dividend on Nov. 3. Shares fell 0.4% in early trading.

Verizon. The nation's largest carrier has its own Nob. 3 dividend planned and, with the help of Motorola, may have a new Droid phone, the Nexus 5, on the way. Shares rose 1.5% Wednesday to $49.87.

Intel. Analysts are wondering whether the chip maker is about to make a dent in the smartphone chip market, a payoff for its $4 billion annual research and development costs. Shares rose 2% on Wednesday.
