I don't really understand it but the TVIX thing is creepy fun. If you haven't followed it, Credit Suisse issued this exchange-traded note called TVIX that was a 2x levered bet on the VIX. They suspended new issuance about a month ago due to position limits, and people were just so damn excited to own the thing that its price crept up to 189% of its fair value, where "fair value" is a reasonably easily measurable thing based on the formula in the TVIX prospectus.
