NNDM is the big runner on the day on news of breakthrough tech in 3D printing chips. I bought at the open and sold into a spike for a small single then watched as it ran from the 1s to almost 4. It is holding nicely a/h. This one filled the long term gap nicely so I will be watching for continued action tomorrow.

ACER spiked at the close on CV news via twitter. I'll be watching in aftermarket to see if this has legs and will continue to spike tomorrow with PR.

HTBX had a nice FGD after earnings a few days ago. Watching for PR to drive it higher.
