sell off shares while the market in panic ，and short a large number of shares to drive down the price, causing the boss to face margin calls and liquidate their positions. Then, buy back the shares at a lower price to cover the short positions. After that, sell off again. Through these two rounds, this big guy acquire a large number of shares at a low price from the boss. Assuming the average short selling price is 60 and the average covering price is 40, the cost of the shares in hand might only be 30. Will there be two more rounds? Can the boss borrow some help to counter this? If the boss finds a benefactor and drives the price up, the short sellers will get burned, and the stock price will hit the upper limit. If the short sellers are satisfied, they might drive the price back up after covering their positions.
