Will we have the same 1987 Black Monday?

I see now why people predict the stock market will drop again..

People are reminded of a very serious and dramatic event that happened on October 19, 1987. It was when Wall Street shares fell 23 per cent in a day and triggered a cascading global effect...

Many analysts tried to compare today's condition with the past' and tried to conclude that the condition is different so we shouldn't have the same impact as in the past. But I still think the market can't be easily predicted. People's fear and rationality drive the movement.
Just put on your seatbelt. We'll wait and see...
