Shares of three technology giants soared Friday after earnings, but one analyst believes Apple lacks a catalyst for a similar spike when it reports next week.
Amazon, Google parent Alphabet and Microsoft all beat quarterly expectations after the bell Thursday, partly on strength in growth segments like cloud computing or mobile advertising. But the smartphone market, which drove Apple's momentum in recent quarters, has slowed, said Brian Blair, principal at Grays Peak Capital.
"Apple is experiencing a sector that is slowing. Smartphone growth is slowing globally and investors have been pulling back from it because, while Apple's involved in a lot of exciting areas, none of them are moving the needle any time soon," Blair told CNBC's "Closing Bell."
