True... they other key here is for us to HOLD OUR SHARES.
ATRN could be working with a broker/MM to accumulate shares. MMs know how to shake investors. Appears to me that noone has determined the cause of last week's sudden 100% PPS run. Perhaps MMs let it run leading up to that bush league "negative" PR. Make sense to me, raise ATRN to high alert, release "negative PR, then retail buyers sell in fear, ATRN accumulates the shares.
Just my opinion, of course.
