Probably the opposite. Corrections happen quickly and all at once, somewhat similar to growth.

It would be more surprising if the 30% drop was spread out over a month.

Correct, momentum acceleration is generally a mean reversion signal in futures, and can be effectively combined with momentum signals i.e. you go long when it goes up but when it starts going up a lot you reduce your position.

And these signals are usually very compressed in time because acceleration is actually just an acceleration in the number of decisions being taken, which tends to blow off quite spectacularly.

Something that has changed is the large retail participation, which is making the scale of these moves quite crazy. Will be interesting to see what happens next, as with crypto the scale of the wipe seems so large that it is hard to see how that participation continues.

Healthy for markets but I am guessing this will conflict heavily with the politics.
