The Direxion Daily AAPL Bull 1.5X Shares (AAPU) closed down 0.31% at $31.81 on February 5th, as Apple Inc. (AAPL) shares faced pressure amid reports of a potential regulatory probe by China's State Administration for Market Regulation (SAMR) into the company's App Store fees and policies. Apple's stock, which fell 0.28% to $232.15, was impacted by concerns over the SAMR's scrutiny of its 30% commission on in-app purchases and restrictions on third-party payment services. This regulatory pressure comes at a time when Apple is already grappling with declining sales in China, its largest market outside the U.S., and increased competition from local companies like Huawei. The potential investigation is part of a broader regulatory push by Beijing, which could further strain U.S.-China trade relations.
