NEW YORK (TheStreet) -- Investors who are selling short Skyworks Solutions (SWKS) - Get Report should be careful, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said on CNBC's "Stop Trading" segment. 

It is a Friday in mid-summer, and trading volumes are light, which can make it easier to push stocks around, he said.

Shares are down 3.5%, despite the company beating on earnings-per-share and revenue estimates for the fiscal third quarter and providing strong guidance. 


Cramer said that shorts are betting on a deteriorating situation in China, but Skyworks Solutions Chief Executive David J. Aldrich said that the region is still good for business.

Aldrich is also bullish on the Internet of Things business. 

Apple (AAPL) - Get Report remains a big customer of Skyworks Solutions, as its iPhone sales continue to be robust, Cramer said.

The takeaway: The stock is down on the day, but shorts shouldn't get too confident and instead should be cautious, he said.

At the time of publication, Cramer's Action Alerts PLUS had a long position in AAPL.
