IV rank says where a ticker's implied volatility sits inside its own 52-week range, as a number from 0 to 100. A rank of 0 means today's implied volatility is at that ticker's 52-week low, 100 means it is at the 52-week high, and 80 means it sits 80 percent of the way from the low to the high — which is the context a raw premium number cannot give you.
It is a position, not a level: today's implied volatility measured against that ticker's own high and low over the past 52 weeks.
A rank near 100 means the option market is pricing more movement than it usually does for this name. A rank near 0 means less.
IV percentile answers a neighbouring question — the share of days in the past year when implied volatility was lower than it is today.
Implied volatility on its own does not compare between tickers: 45 percent is high for a utility and low for a small-cap biotech.
IV rank makes the comparison fair by scoring each ticker against itself.
It means the premium is high relative to this ticker's own year, which is the right place for a seller to start and not the place to stop.
Two puts can show the same yield with opposite IV ranks. The high-rank one is paying for volatility that is unusual for the name; the low-rank one is paying because the strike is close to the money.
Liquidity. A wide spread or a zero bid will not fill at the price the screen showed, however good the rank looks.
A known event. Implied volatility is often high because earnings fall inside the expiration, and the premium is compensation for that risk rather than a gift.
The IV Dashboard lists it per ticker across the names Remora tracks, and the Options Screener carries it on each result row.
From an AI client it is the get_iv_rank tool. get_option_quote returns bid, ask, greeks, implied volatility and breakeven for one specific contract, and get_earnings returns the date.
When Remora has no usable window for a ticker it reports the rank as unavailable rather than printing a number it cannot stand behind.
The Saber system is where the rank sits inside a wider score, with the per-component breakdown shown.
Yes. "What is NVDA's IV rank, and is the premium on the 30-delta put rich or cheap?" is the kind of question it answers once Remora is connected.
