Okay, so it works like this:
The price of the turbo depends on the relevant VIX future (sept in this case) and the 'financieringsniveau' (financing level) of the turbo.
VIX sept is 15.18 (Ref.) and finance level is 23.21. So difference is 8.03 USD, which is 6.86 EUR. Stoploss is at 20.89 for the VIX future... at which case you still get 2.32 USD (1.98 EUR) for the turbo.
If VIX sept drops to say 12... the value is 23.21-12= 11.21 USD (9.58 EUR).
The 'hefboom' (leverage ratio) is 1.93... which is price of the VIX Future/turbo... in this case, 15.18 / 7.95 USD (6.80 EUR) = 1.91
They both move 1:1 .... 1 point in VIX is about 1 USD in the turbo (0.85 Euro).
You're paying 2% financing cost... which is incorporated by (daily?) lowering the Financing level... (or so I think it is, if I remember correctly).
It's rolled-over every month I think, adjusted to the next VIX future...
So there it is.... it's a leverage VIX future short, with a stoploss at 20.89
BNP Paribas makes money on the fact that it's priced slightly rich (about 1.5%) and with the 2% financing they charge... which is ridiculous, since VIX futures are daily settled and you're paying all upfront with the turbo... so in effect they are receiving net cash... and charging you for it
(PS. no, you can't short the turbo itself to arb it)
