Analysts were left with more questions than answers about Apple's new services that were unveiled at a press event.

The new services announced Monday include Apple News+, Apple Card, Apple Arcade and Apple TV Channels.

"Apple's services reveal was materially different than we had anticipated," said Goldman Sachs analyst Rod Hall. "With small calculated impacts from these, 'other services', we expect the focus to return to the slowing iPhone business post this event," Hall said.

Shares of the stock declined after the event but were up over 1.6% at the open.

"Overall, it appears that Apple's new services provide better solutions to solve relatively niche problems in media business and they may prompt existing iOS users to stay more invested in Apple's ecosystem," Oppenheimer analyst Andrew Uerkwitz wrote in a note to clients after the event.

"Pricing of Apple TV Plus is one of the biggest unanswered questions we have after the event," Uerkwitz added.
