Buy Put on the VIX

VIX US 11/21/18 P22 Index or VIX US 11/21/18 P20 Index
We believe funds selling (risk parity and CTAs) is not over but a bottom is being built. We like going short the VIX without the risk of being washed out, simply by buying Put. find more on the microstructure of the current sell-off here.

Update on october 23: we hedge our long put with long VIX future on November
