Isn't that just some kind of clearing transactions that should have gone through during regular trading, but for some reason didn't. I've heard this as an explanation on numerous boards when large blocks go through. Best
My data feed indicated that was a trade 100k AH. MMs tend to shake really hard to the down side when they have large orders to fill. I suspect you witnessed institutional accumulation today on a low float-China-fertilizer-accelerating revenue-acelerating earnings stock. Now you can expect low volume for a few days and then a repeat of the process at higher prices. As a savy retail investor, you get into position on the long side.
