According to the data from VIX, it has risen by nearly 30% today, currently at 27.24. Generally speaking, exceeding 30 is a time of extreme market panic. Moreover, based on the data from the past year, there will be a greater chance of rebound after VIX exceeds 30. However, it should still be noted that even if there is a rebound, it may only be a rebound, and there is still a long way to go before it reverses.
