ETF Relative Value / Pairs
One ETF vs another
What it is
Trade the spread between two ETFs — long the stronger, short the weaker (tech vs broad, cyclicals vs defensives, developed vs emerging, semis vs broad tech). Also covers the dedicated vol-ETP pair: long a well-designed short-vol product (SVIX, SVOL) against a short of a decay-prone long-vol product (VXX, UVXY) when the VIX curve is in contango.
When it works
Two related ETFs at a stretched relative spread with a thematic reason to prefer one side; or a vol-ETP pair when the VIX term structure is in contango (long-vol decay funds the short-vol carry).
Why the setup pays
Direction = Neutral; you isolate relative performance and hedge out broad-market beta. The vol-ETP pair specifically harvests the asymmetric decay between a well-structured short-vol product and a structurally-decaying long-vol product.
The market it wants
High dispersion. Regime transitions and high cross-sector dispersion; the vol-ETP pair specifically requires VIX in contango — an inverted curve breaks the thesis.
What goes wrong
The spread widens before converging; a macro shock moves both legs together; the vol-ETP pair breaks if the VIX curve inverts (vol-spike risk).
Where it sits in the book
ETF Relative Value / Pairs belongs to Linear Risk Premia & Style Factors, the group whose edge comes from mean or trend of the distribution. That group looks for sustained trend extensions, or clear overextensions for mean-reversion, and its risk profile is dynamic / path-dependent directional.
Run this on the live market
This is the thesis the engine scans with. It reads the whole universe, scores what matches, and prices the structures against fair value.
