Vol Relative-Value Screener · Foundations

Rich vs Cheap, Across Names

One implied-vol number tells you nothing by itself. Comparing it cross-sectionally — against every other name at the same moment — tells you where the edge is sitting today.

A single implied-vol reading answers nothing on its own. NVDA vol at 60%: rich or cheap? It depends on what NVDA usually does — that's the time-series question — and it depends on what every other name is doing right now — that's the cross-sectional question. Cross-sectional relative value is the comparison of implied vol, VRP, and skew across all names at a single point in time. The Vol Relative-Value Screener is built to make that comparison systematic.

Why cross-sectional ranking matters

Options don't exist in isolation. If you're looking to sell premium, the question isn't just "is AAPL vol elevated?" It's "which name in the universe is paying me the most per unit of risk I'm taking on?" If you want to buy protection cheaply, the question is "where is implied vol most depressed — not just versus its own history, but versus the universe today?" Cross-sectional ranking answers both in one pass.

This matters even more when all names are elevated. A broad vol spike — a macro shock, a sudden regime shift — can push every name's implied vol above its own historical 75th percentile simultaneously. On the Cones tool, every name looks rich. On the Screener, you can still rank them and find the relatively richest — the one where implied is stretched furthest beyond what the cross-section would predict for its normal vol level.

The Variance Risk Premium as the cross-sectional signal

The Variance Risk Premium (VRP) — implied vol minus realized vol — is the backbone of the cross-sectional ranking because it's normalized. A 60% implied on NVDA and a 15% implied on IEF can't be compared directly; but if NVDA's VRP is +12% and IEF's VRP is −3%, the comparison is immediate: NVDA is rich (sellers paid), IEF is cheap (protection underpriced). The VRP strips out the level effect and gives you the premium in the same unit for every name.

The other columns add context

VRP is the headline signal but the screener gives you more. Term Slope tells you whether vol is in contango or backwardation for each name — the shape of the implied curve in just two columns. RiskDex® adds directional skew: is this name pricing downside fear? The 1-year columns — IV Rank, IV %ile, and the VolDex® z-score — add the time-series layer back in, so you can see whether the richest name cross-sectionally is also historically elevated (double signal) or merely elevated in cross-section while being modest versus its own history (weaker signal). Each column adds a dimension; the ranking across all of them is the trade idea.

Pair ideas: sell the rich, buy the cheap

The natural output of a cross-sectional screener is a vol pair: sell premium on the richest name, buy premium on the cheapest, and pocket the spread. The position is less exposed to a broad vol move — if the whole market reprices, you're partially hedged — and more exposed to the relative correction that the screen is predicting. That's the classic vol relative-value trade structure, and the screener is the entry point for finding the two legs.
