Short sellers are fishing for liquidity
Imagine being a farmer looking for water. You start digging a well. 10 meters deep no water, 20 meters deeper still no luck so you keep digging deeper and deeper hoping to find enough water to justify the investment and time spent digging. Now imagine a bunch of short sellers who sold millions of shares short and are digging/fishing for stop loss orders or people who will be forced to sell at a certain price (those who bought on margin and can't honour repeated margin calls for more cash as the price keeps going down…) that will allow them to cover their shorts. Short sellers will do anything to push, force or convince you to sell because they are sitting on millions of shares that they must buy to cover their short positions.
