The biggest losers in the market: Pro

China's plunging currency worries investors because many consider the Chinese data unreliable, not to mention the huge stockpile of reserves, said Elsa Lignos, an RBC currency strategist, in a Thursday interview with CNBC's "Closing Bell."

"We had data overnight showing they used up over $100 billion in December alone," she said. "That has implications for other asset classes; the heavily invested in U.S. Treasuries" and currencies.

Amid these fears, market watchers are looking to invest in companies that will have fewer repercussions in the wake of China's volatile market.

On the exposure side, you have a lot of tech, industrial, material and the energy companies, said Paul Hickey, co-founder of Bespoke Investment Group.

"Qualcomm, Micron, Broadcom," he noted. "These chip-related companies have a lot of exposure there. While the band doesn't necessarily stem from China, they have a lot of their sales in China."

Market watchers may fear that China may ruin companies such as Apple, Starbucks and Tiffany, but Hickey suggests that investors look at valuations.

"Fears on China sales are a little bit overblown for Apple," Hickey said. "Following the August sell-off in Apple's most recent quarter ... sales continue to be consistently strong; triple-digit revenue growth."

Apple closed down 4.2 percent at $96.45 a share on Thursday.
