Twitter was due to announce its earnings for the first quarter of the year after close of trading on the New York Stock Exchange, where the company is listed.
Except it turns out that somebody thought it would be a good idea to release this information early, on the technology-led NASDAQ run Investor Relations page for Twitter.
Initially it seemed no one really noticed the error, until a well-placed tweet highlighted the mistake and revealed Twitter's disappointing results.

At one point in the final hours of trading, the stock had lost more than $8 BILLION.

The "correct" value of a company is how much its dividends will pay from now to eternity (corrected with inflation etc, of course). The stock price should reflect the current approximation of that. If it's obviously more or less than that, we are dealing with gambling rather than investment.
