After all of Apple's investment in China, their shares fell on Wednesday after the Chinese regulators are considering whether to open a formal probe into the iPhone giant’s App Store fees and policies. Shares of Apple are down 2.2% as of 9:06 AM EST.

The State Administration for Market Regulation (SAMR) is looking into policies that include Apple taking a cut of as much as 30% on in-app spending, as well as blocking third-party payment services and app stores, Bloomberg reported Wednesday, citing people familiar with the matter.
