Apple Inc. has become the worst-performing Big Tech stock in 2025, with its share price dropping nearly 25% this year, following a disappointing announcement at the Worldwide Developers Conference.

Despite generating over $166 billion in revenue from iPhone sales in the past year, the company has seen stagnation in sales growth, with only a 2% increase, as consumers are less inclined to upgrade their devices.

The iPhone, which accounts for approximately 52% of Apple's revenue, has faced declining sales due to longer upgrade cycles and increased competition from local brands in China.

Apple's market share in China has significantly decreased from 21% in late 2023 to 15% in early 2025, as local competitors like Huawei and Xiaomi gain traction.

Concerns about Apple's current product offerings not providing compelling reasons for consumers to upgrade have led to fears that customers might switch to more innovative brands.

Given the combination of slowing growth, high valuation, and external pressures, analysts suggest that now is not a favorable time to buy Apple stock.

Apple's stock, trading at about 31 times its trailing earnings, is seen as expensive, particularly in light of its stagnant net income since 2022.

The company's services segment, which has grown significantly in recent years, faces threats from antitrust lawsuits that could undermine its profitability, particularly concerning the App Store's payment policies.

Ongoing trade tensions between the United States and China pose additional risks to Apple's supply chain, as most of its devices are manufactured in China.

Apple has struggled with its AI initiatives, disappointing users and investors due to its reliance on external partners rather than developing its own integrated AI solutions.

A recent court ruling allowing app developers to market cheaper payment methods could reduce Apple's high-margin App Store revenue by an estimated $10 billion annually.

This decline in Apple's stock performance sharply contrasts with the positive performances of competitors like Meta, Microsoft, and Amazon.
