Apple stock could get a boost, a positive sign for Apple investors, because the company is reportedly moving into the server business with its own chips.

• Apple is in talks to build servers powered by its own chips.
• That would put Apple in direct competition with Nvidia in the data-center market.
• The servers would still use Nvidia's networking hardware, so Nvidia keeps a piece of the business.
• A second reason for the bullish case was teased but not spelled out.

Outlook: If the server push goes ahead, Apple gains a new growth story beyond the iPhone, which could push the stock higher.
