IMO the drop was exacerbated by indecision which then allowed bear side traders to create fear selling followed by stop running. The time to buy was lower for max safety. When you buy now depends on your risk tolerance (may be volatile for a while yet) and what you think the combined company present value, potential future value and stability is. What short time frame catalysts (news events) can propel share price so your position is immediately green.
If a chart trader, just follow your signals.
Best wishes.
