Yo Wookie,
Volume may have been up because there is apparently, yet again, an amendment to the filing. Although it has not yet been made public.
Showing today that the Bid-Ask that was 0.0002-0.0003 is now today, 0.0001-0.0002. The hit on SP with big volume may be a taddle-tell as there is always a leak somewhere.
Might be something more negative than current happenings, whatever that could be and is anyone's guess, in the amendment.
