If the drop is that steep, it would most likely keep going until it moved sideways. Margin calls would be flying in if the drop was that sudden, which could happen with the amounts of debt holding stock. Debtholders will want to get paid and the early margin calls are likely to get some of their money back. Those that wait too long will get toasted. It would most likely move down until May 2020 at the earliest and then head up again.
