Apple (NasdaqGS: AAPL) shares continued to rally Thursday despite losses for the major U.S. stock indicators. An exchange traded fund indexed to the Nasdaq-100 that counts Apple as its top holding was in the green Thursday along with the tech stock.

Apple iPhone 4S will be unveiled Friday and wireless carriers are already sold out, according to reports.

Sales for Apple’s new iPhone 4S surpassed 1 million in the first day of availability, breaking the company’s own record of 600,000 sales for the iPhone 4.

The new phone hits the stores this Friday, but rumors are that SmartPhone fans are disappointed because the device appeared a mere follow-up to the previous iPhone 4. Analysts say the iPhone 4S is still a huge draw because more wireless companies will be stocking it and it is going to be distributed to more countries, reports Reuters.

“Many potential Apple customers, who have been on the fences before, will probably now want to (buy) it,” Steven Osinski, marketing professor at San Diego State University said. [Apple’s Bounce at 200-Day Moving Average Powers Nasdaq ETF]
