Por manipular las acciones:

Since at least June 2008, JossefKahlon, a/k/a YossefKahlon, ("Kahlon") through
his corporate entity, TJ Management Group, LLC ("TJM"), (together, the "Defendants") have abused and misused both a federal securities registration exemption and a Texas securities registration exemption to illegally dump billions of shares of penny stock into the public market without registration. TJM's business model was predicated on acquiring large blocks of stock from small companies in multiple successive transactions at a price of at least 40% less than the prevailing market price and quickly reselling the stock into the public market without registration. TJM and Kahlon have reaped at least $7.7 million in profits from this illicit penny stock distribution model.

Entiendo que deben haber suspendido la cotización.

Un saludo,
