There is nothing that will stop the price from falling and there is no mechanism to stop the fall, safety nets do not exist in the real world. It is rare however stocks can and do even go into a negative split. What happens when a stock gets under a dollar is this: 1. A delisting letter goes out to the company from the NASDAQ
2 the warning is that the company has 90 days to remedy the violation themselves
- If the violation is only that the price is under a dollar the company will have another 120 days after the initial 90 to remedy the situation
4 If these measures fail the stock is delisted
5 If bankruptcy is declared trading for the stock is halted
