The ride may be over for the stocks of Apple Corp.'s (NASDQ:AAPL) suppliers once the company makes its Sept. 9 new-product announcement. The stocks, Skyworks Solutions (NASDAQ:SWKS), InvenSense (NYSE:INVN), Avago Technologies (NASDAQ:AVGO) and RF Micro Devices (NASDAQ:RFMD), have all seen their shares rise with Apple's ahead of the announcement, but Barron’s, the weekly financial paper, said once the news is out, the sentiment may turn against them and other Apple suppliers.

With just a little over a week until Apple's much-anticipated Sept. 9 launch event, the iPhone 6 rumor season is coming to a close. The Cupertino, California, tech giant hasn't released any official details about the next-generation iPhone, but a flurry of recent part leaks and rumors have given fans a better idea of what's in store.

According to Barron’s, Skyworks stock has doubled in the run-up to Apple's news conference, while InvenSense is up almost 25 percent, Avago has gained more than 50 percent and RF Micro has jumped an amazing 142 percent. During that same period, Apple shares have run up 30 percent.

According to Yahoo Finance, these are the businesses the four Apple suppliers are in:
