My guess

A middle of the day tree shake.
Accumulator looks like they've dumped a bit to drop the price and make it look like "it's all over folks" in the hope of stimulating a general exodus.
Clearly no leaked news driving this (or no imminent leaked news).
Nice they want to accumulate - let's hope it's not just to dump them later.
If I am right, they'll either have another run at it this afternoon, or wait a day or two.

But really, it's just a narrative that fits the facts.
I've no idea, except knowing that it isn't widespread genuine buying.

The net result is the price is all over the place like a mad woman's breakfast.
