Apple Inc.'s stock has slipped about 1.5% this week due to expectations of a fourth consecutive quarter of declining revenue and increasing competition in China. Despite the recent decline, Apple's shares are still up by almost 36% since the start of the year. Analysts are concerned about weak U.S. sales and increased competition from Huawei in China. A report from Jefferies indicated that Apple has lost its leading position in the handset market share in China. UBS analysts also highlighted risks to the iPhone 15 Pro handsets, which they believe are showing signs of weaker demand compared to last year's iPhone 14 lineup.
