Meta makes $30 billion a year. It is not a shit performing business. In fact it is one of the best businesses in history. Their stock bounceback isn't because of the layoffs, it's not because investors were actually worried that meta's business was bad. It was because they worried Mark had gone rogue and since he's the controlling shareholder investors have no way to stop him. The layoffs were just the way for him to signal that he still has investors interest at heart.
