Some CNBC report in December had the Barclay's info. But you can read about it in public documents as well:
Barclays, in the VXX PPM (well over 200 pages long BTW), they expressly disclose that their investment arm, barclays capital, inc. "may acquire a short position in the VXX ETN."
Go read the audited financials of Barclays capital, inc., they have HUGE short positions in the ETN's they trade (not surprising if you go read the returns on the ETNs they offer).
Basically, as far as I can tell, its a huge scam that nets them piles of money. Basically:
1. Offer ETN, charge fees to do it;
2. Collect interest on ETN sales;
3. Trade against ETNs at the same time you sell it to other because you know its going to decline in value.
I'm sure Barclay's would just say, because they are the market maker, they're hedging their position. That's a load of BS. Who in their right mind would continue offering an instrument that loses well north of 50% of its value EVERY YEAR? If I was on a trading desk and designed a strategy to lose my customers over 50% of their money each year, I'd be fired in 10 seconds -- unless the sale to my customers made my company millions.
Sorry if this sounds like conspiracy, but there's simply no way this type of thing should go on.
That said, as it makes me money each quarter, I don't know why I gripe.
