NAK IV Rank & Percentile
Where NAK’s implied volatility sits inside its own 52-week range — the single number that decides whether buying or selling premium is the side being paid on this name today.
Open interest and pricing as of the close on 2026-08-28. Recomputed every morning before the open.
Options are cheap versus this name’s own past year — the side that favours buying premium.
IV LOW - good value
Cheap compared to what?
An IV rank is measured against the name’s own history, which flatters a stock whose volatility has been structurally falling all year. These are the same reading scored against two wider frames.
| Frame | Value score | Reads as |
|---|---|---|
| NAK vs. its own 52-week | 8.2 | The headline rank above |
| vs. Basic Materials | 5.0 | Against names that move for the same reasons |
| vs. the whole universe | 5.0 | Against every optionable US name we score |
Blended, these give NAK a Value pillar score of 6.72 out of 10 — “Reasonably priced options”. How the pillars work.
IV rank, explained
What does an IV rank of 18 mean?
It places today’s implied volatility inside the name’s own 52-week high-low range. A rank of 0 means IV is at its cheapest of the year, 100 at its most expensive. It says nothing about direction — only about what NAK options currently cost relative to what they normally cost.
IV rank vs. IV percentile — what’s the difference?
Rank uses only the high and the low, so one spike stretches the whole scale. Percentile counts the share of days that were cheaper than today, so it is unmoved by a single outlier. When the two disagree sharply, the year had an extreme day and the percentile is the more honest read.
Why does the IV/HV ratio matter alongside it?
IV rank is self-referential — it compares NAK only to itself. The IV/HV ratio compares what options are pricing against how much the stock has actually moved. Low rank plus a ratio below 1 is the genuinely cheap case; low rank with a ratio well above 1 means options look cheap historically but are still charging more than recent movement justifies.
Does a low IV rank mean I should buy options?
It means premium is cheap by this name’s own standards, which is a necessary condition for buying, not a sufficient one. Volatility is usually low because nothing is happening — you still need a reason to expect that to change. Check the timing pillar for what is scheduled, and IV crush for what happens after it does.
