If someone could find out what ETPs these are, they could short it. Then if the SEC acts, they could rake in dough.
It is most likely an ETN, those things are full of garbage. Only suckers buy them anyway.

The whistleblowers state that much of the ETP's "asset base" consists of synthetic/derivative positions ... They're just words on paper with no assessment of the counterparties ability to cover...
YES , I too would like to short these beasts but as they are SEC protected wall street fraud vehicles I'd always be afraid of manipulation ... I personally suspect that his is how wall street creates fictional shares of companies so that they can pretend that they are shorting borrowed shares instead of admitting that they are completely naked (an illegal market manipulating practice that the SEC has NEVER INVESTIGATED OR ENFORCED).
