Berkshire Hathaway (BRK.A) Up 51% in After Hours Trading

  • Would it be just one rogue order filled? Not sure how after-hours tracking works, but I assume that it won't have a very deep order book, so it would be relatively easy to manipulate it. Given that BRK.A has the highest share price among any stocks, that order book would be even smaller.

  • We assume that hedges / banks are moving their money into higher quality assets before the new margin requirements take effect on October 29th.

  • Another one, not quite 51% this time.
