Why it matters
What this buys you
on the desk.
How traders read Relative Value Scanner when they are looking for an edge worth taking.
Find Relative Richness and Cheapness
A ticker might have IV rank at 50 — middling on its own. But if its IV/SPY ratio is at the 95th percentile, it's extremely rich relative to the market. That's your edge.
Trade Pairs for Market-Neutral Vol
The pairs generator matches rich tickers against cheap ones with adequate correlation. Sell vol on the rich, buy on the cheap — your P&L comes from the spread normalising, not market direction.
Quantify with Z-Scores
Z-scores tell you how many standard deviations from the mean the ratio sits. Above +2 is a statistical extreme that tends to revert — the entry signal for relative value trades.

Questions
What people ask
about this screen.
What benchmarks are used?
Each ticker is compared against SPY (broad market) and its sector ETF (e.g. XLK for tech, XLF for financials). Both ratios are tracked with z-scores and percentiles.
How are pairs selected?
The scanner identifies tickers at opposite IV rank extremes, filters for minimum correlation (ensuring the pair moves together), and ranks by spread width and mean reversion probability.
