Direxion Daily Gold Miners Bull 2X (NUGT)

[Surfint]

We were confused by EO day friday; trimmed back NUGT ( at 38ish) to hold a position size same as DUST. If they can move the same percentages, hopefully it's a wash until the market of either has clear direction. Maybe the direction is already set with DUST; we have a hard time letting go of NUGT totally. If anyone has a good hedge/parity/carry trade strategy, we are interested in hearing it. Our guess is that NUGT might decay a little faster than DUST but it's just a guess. We can appreciate complex math if that's what is required to describe a hedge/parity trade. Looking for good references or examples on "how to." Thx.
