No mention of the fact that FB or Meta was grossly overvalued in the first place and its rise and rise had generated hundreds of billions of dollars of gains & wealth for Mark & FB shareholders. They are only giving back some of the inflated gains.
Not so good obviously for the traders who bought (especially those using leverage like call options) in the last week in anticipation of a great result.
