ZB buys Tenax May 18th and on June 2nd he sells along with announcement of what looks like good Phase 2 data. With Sintx he appears and buys at .72 right before Sintx announces Si3N4 kills Covid and then sells for close to 4 times that.
So I thought ZB was part of a wolf pack but instead found hes part of Hudson Bays pump and dump, or in Sintx case pump and then reshort.
