Apple's market capitalization has surpassed Microsoft to become a brother in the market. In fact, the credit is the iPhone 11 series. On Friday, US stocks rose 2.7% to close at $236.21, hitting new highs and surpassing the highest point set a year ago.Apple once again squeezed Microsoft out and became the world's most valuable company. However, both Apple and Microsoft have a market capitalization of more than $1 trillion.Apple's share price has climbed 60% compared to the January low, and the market value has once again exceeded $1 trillion. In the fourth quarter of 2018, Apple’s share price was weak due to concerns about weak iPhone demand, and this concern seems to have eased in 2019.Although Apple is paying more and more attention to the service industry, the iPhone is still the core product of Apple. In the third quarter, iPhone revenue accounted for about half of Apple's total revenue, and service revenue accounted for only 21.3%. On October 30, Apple will announce its fourth-quarter earnings.Analysts however, expect Apple's fourth quarter earnings per share will reach 2.84 US dollars, revenue of 62.9 billion US dollars, which means that revenue will be reduced by 2.6%, revenue growth remained stable.At present, foreign countries are very optimistic about Apple, and believe that the launch of 5G mobile phones next year will drive the market to renew, but the problem now is that the continued low price may lower the average price of the iPhone.
