Facebook leaked user data scandal, fermented market value evaporated by $58 billion in a week.

　　Facebook’s scandal of leaking user data continues to ferment, and its company’s market value has evaporated by 58 billion US dollars in the past week.

　　On the 22nd, Zuckerberg, the founder of Facebook, apologized for the incident and promised that similar incidents would not happen again. However, such a solution obviously cannot satisfy the outside world. The company’s share price dropped from $176.80 on Monday (19th) to about $159.30 on Friday (23rd).

　　Facebook’s initial public offering price was $38 per share in 2012, when the company’s market value was close to $104 billion. With the steady growth of Facebook users and the huge profits brought by digital advertising implantation, Facebook’s share price climbed to $190 in February this year.

　　According to Facebook’s recently released 2017 annual report, Facebook’s revenue from advertising business in fiscal year 2017 was $39.942 billion, accounting for 98.25% of the total revenue, up 49% year-on-year. CNN pointed out that the "mining" of user data has been written into the "gene" of Facebook, and the purpose of doing so is to make a profit.

　　Rice, a senior analyst at Hargreaves Lansdowne, a famous British investment platform, said that data leakage was a "destructive event" in the history of Facebook. He also said that Facebook is successful because the more people use it and the longer it takes, the more people rely on Facebook. But unfortunately, if a large number of users are lost because of this scandal, the losses will also be huge.

　　Brian Weiser, a senior analyst at Pivotal Research, an American market research company, said that he is currently the most pessimistic about Facebook’s share price. Weiser said that the stock price crash shows that investors are cautious about increasing supervision and users leaving the platform, but advertisers are unlikely to leave Facebook.

　　Public opinion generally believes that the 14-year-old Facebook company is facing the biggest crisis since its establishment. After the news that 50 million users’ data were leaked and the regulators intervened in the investigation, not only did the share price of Facebook plummet, but more seriously, the information leakage incident shook users’ trust in Facebook, and "deleting Facebook" has become a big topic tag on social media.

　　At present, several US congressmen have asked mark zuckerberg, CEO of Facebook, to go to the Senate Judiciary Committee to answer questions about this incident. Damian Collins, chairman of the Committee on Numbers, Culture, Media and Sports in the lower house of the British Parliament, also asked Zuckerberg to provide relevant evidence to the British Parliament. The EU will also summon Zuckerberg to explain.

　　Regarding the disclosure of Facebook users’ data, the British Information Regulatory Authority applied to the court for a search warrant, and after being approved, it sent investigators into Cambridge Analytica’s office in London. A spokesman for the British Information Regulatory Authority said: "This survey is only a small part. The whole survey will involve personal data being analyzed and used for political purposes. We now need to collect information, evaluate and examine the evidence before we can reach a final conclusion. "
