Many investors (long or short) place what are called stop orders to protect their positions from steep losses.
For a long investor, you might buy a stock at $100, watch it go up to $150 and enter a sell-stop order at $130. That stop order has no effect so long as the price stays above $130. When/if the stock drops to $130, the order becomes a market order to sell out, protecting from further losses.
For a short seller, they might place a buy-stop order (at a price higher than the current price) to protect from disastrous runaway price to the high side. Those stops could have been triggered by the run-up after Musk's tweet.
