This is purely a personal "prediction".
The government will probably make an official announcement tomorrow that they will do their best to stabilize the situation. And in response, Hynix will announce shareholder return measures in its earnings release, and Samsung will announce that it will buy back its own shares immediately. Then, the schedule for raising the deposit on August 5th, which was suddenly moved up to the 31st, fits perfectly.
But if investor sentiment is completely broken in the meantime, any remedy will be useless. There's a reason why Trump reacts quickly even when he hears taco sounds. Anyway, I don't know what will happen to the broken sentiment, but I think good news (domestic only) will continue to come out for the next three days. I used to keep it on the upside until the mid-6,000s, but I can't say that anymore from today.
