COMBO PLAY: BIS Bear Bio + XIV combo

Left chart: Combine leveraged ETF BIS (bear, bio x3) with XIV (or safer ZIV or SPLV) for a good deal on risk vs return.
Right chart: BIS about to overtake EDZ (short emerging markets, x3 ETF).

Ratio:
1) currently 1.5 shares of BIS to every 1 share of XIV. This ratio changes over a period of days so must be monitored closely.
2) For less volatile combo's using ZIV or SPLV you will need (much) less BIS
