I saw this recently on BBC News – Facebook owner Meta sees biggest ever stock market loss: https://www.bbc.com/news/business-60255088. Longer article.
Facebook’s owner Meta Platforms saw its stock market value slump by more than $230bn (£169bn) on Thursday, in a record daily loss for a US firm.
Its shares fell 26.4% after quarterly figures disappointed investors.
Meta also said that Facebook’s daily active users (DAUs) had dropped for the first time in its 18-year history.
The company’s share price slide saw chief executive Mark Zuckerberg’s net worth fall by $31bn, according to the Bloomberg Billionaires Index.
