Apple shares tumbled on Tuesday amid renewed concerns about its China business, and one CNBC "Fast Money" trader believes the technology behemoth's struggles have just begun.
"I think the story in Apple is crumbling a little bit," said trader Brian Kelly, adding that investors may want to take profits.
China's surprise overnight move devalued the yuan by about 2 percent Tuesday. With the U.S. dollar growing stronger against the currency, Apple could face a tougher time selling its iPhone in the key market.
The stock fell more than 5 percent to about $113.50 per share. Kelly contended that Apple will face new challenges in an already "well saturated" smartphone market.

But Apple's valuation—at about 13 times earnings—still gives it appeal, said trader Tim Seymour, who owns the stock. Trader Guy Adami added that a sustained drop to $105 per share would provide a strong entry point for a trade.
Alibaba
U.S.-listed shares of Chinese e-commerce giant Alibaba slid nearly 4 percent on Tuesday. The company reports quarterly results on Wednesday, before the market opens.
Seymour—who owns the stock—noted that the company's situation is "getting better." Alibaba shares have plunged more than 25 percent this year amid concerns like China's regulatory environment for Internet retail.

Adami noted that anything "remotely positive" for Alibaba would boost Yahoo shares. Yahoo's stock has moved almost in tandem with Alibaba ahead of the spinoff later this year of its Alibaba stake, which was worth about $30 billion last month.
Yahoo has plummeted nearly 29 percent this year.
