Apple Inc.'s Show-And-Tell Moves Winners And Losers

Apple Inc. AAPL closed Tuesday slightly down after the company unveiled the Apple Watch and latest iteration of its iPhone. But that wasn't the only stock responding.

Just before 2 p.m., tiny Pulse Electronics Corp PULS, with a market capitalization of $55 million, jumped more than 50 percent to $3.19 per share on a rumor it's supplying iPhone components.

The San Diego maker of handset antennae and other electronics got a call from the New York Stock Exchange, but said had it no comment on price movement.

What The Experts Think Of The Apple Inc. Watch

Watchmakers Fossil Group Inc FOSL and Movado Group, Inc. MOV each fell two percent, possibly on concern the Apple Watch will cut into their fashion market.

GT Advanced Technologies Inc GTAT is going to make the so-called sapphire crystals for Apple watches. But investors learned it won't make display windows for the iPhone. Shares tanked more than 12 percent.

eBay Inc EBAY dropped more three percent when Apple confirmed its phone will include electronic payment equipment linked to banks and credit cards. eBay's PayPal unit is widely seen as threatened.

NXP Semiconductors NV NXPI declined 1.6 percent, apparently on disappointment its wireless and mobile chips aren't a significant feature of Apple's new products.

Universal Display Corporation OLED was also a big loser. Its light-emitting diodes used in cellphone displays won't be doing much for the iPhone. Shares skidded down 7.2 percent.
