Apple's torrid growth may start to slow in coming quarters, and its stock performance could lose momentum with it, some CNBC "Fast Money" traders said.

"I'm long this stock. but I do feel like it's running out of a little steam here," said trader Karen Finerman.

Shares in the tech behemoth moved 1 percent higher in extended trading Monday after it beat Wall Street's quarterly earnings and revenue estimates. Sales of iPhones soared past analysts' expectations in the quarter, and Apple also boosted its share repurchase program.

With the stock up 20 percent this year, it may be running out of room to climb, Finerman said. But trader Guy Adami contended the results will prompt "the next phase higher" to $145 per share, about $10 up from where it traded after earnings.

Trader Pete Najarian—who has a long stake in Apple—looked to some producers of Apple components. Chipmaker Cirrus Logic has moved with Apple, he noted, and is up 42 percent this year.

It reversed losses from Monday's session in extended trading, going 1 percent higher to about $34 per share.

Chipmaker is a play in "the entire smartphone space," while China Mobile distributes iPhones in China, Najarian noted. Broadcom moved higher in extended trading Monday, while China Mobile was slightly lower.

Trader Dan Nathan was wary of semiconductor stocks.

"I think they're kind of value traps," Nathan said.
