The announcement of a new antitrust lawsuit by the DOJ against Apple for allegedly restricting competitors' access to iPhone features is likely to have a negative impact on Apple's stock price in the short term. Legal challenges, especially those related to antitrust issues, can lead to uncertainty among investors, potentially affecting the company's market valuation. Additionally, the lawsuit is part of a broader crackdown on tech giants by the U.S. government, indicating a potentially challenging regulatory environment for Apple moving forward. The recent fines in the EU and Russia for similar issues underscore the global scale of legal challenges Apple faces, which could further concern investors.
