Anyone who knows the stock market would know from looking at that image that it was a mistake. Such a sudden 99% drop cannot happen in a company with such a share price. Just by looking at the shares held by Apple, Bank of America or Coca Cola, which has a market cap of about $1T, such a drop could only happen by exploding multiple atomic bombs, in which case the stock price would be the least of our worries.
The only reason for such a drop being unlikely is the amount of time it took. When it is in matter of minutes, it is most probably a glitch.Otherwise a huge drop like 90% to 99% is not an impossible drop for any corporation. Or even its price being certain high value is not a reason for it not to have such a big dump. In other words there is no such thing as "too big to fail".
Off the top of my head I can refer you to the German energy giant called Uniper. Back in February 2022, it got dumped 50%-60% and the dump continued until a couple of months later with a total loss of about 95%.
Their stock was once worth €840 (Berkshire Hathaway is worth $409) and it is currently worth about €50.
That's pretty much what we saw with BRK but it took a couple of months. So it is obviously possible to see such dumps in stock market as well without any bombs going off.
