Fortinet — Implied volatility rank, VRP edge, and volatility regime
Fortinet (FTNT) operates in the Information Technology sector and has actively traded listed options. Its IV Rank reads 37.5%, mid-range within the past year — neither cheap nor rich. VRP of +8.0pp shows options are meaningfully overpricing realized movement. Average IV can work with directional or defined-risk structures. See Expected Move for strike placement.
This helps you judge whether implied volatility is elevated enough to justify selling options. High IV Rank means premiums are rich compared to the past year.
IV Rank above 50 generally favors premium sellers — you're collecting above-average premium.

IV Rank uses a fixed 1-year lookback. Regime changes (e.g., post-COVID vol reset) can distort the range. IV Rank alone does not indicate direction.

Fortinet's IV Rank of 37.5% means premiums are in the lower portion of the 252-day range. Absolute premium available per contract is reduced, which compresses potential returns for sellers. However, low IV Rank doesn't necessarily mean selling is wrong — if VRP is still positive (currently +8.0pp), options may still be overpriced relative to actual movement. The win rate can be high in low-IV environments because the stock is genuinely calm.
Fortinet's IV Rank measures where current implied volatility sits relative to its 252-day range. At 37.5%, it indicates how rich or cheap options premiums are compared to the past year. Premium sellers generally prefer IV Rank above 30–50%, as higher IV means more premium per contract and a greater statistical edge — assuming VRP confirms actual overpricing.
VolRadar's signal prioritizes relative mispricing (RV Ratio) over absolute premium level (IV Rank). A ticker with low IVR but very low RV Ratio may show a Strong signal because options are significantly overpriced relative to actual movement. For richest absolute premiums, check IV Rank (>50%). Not financial advice — quantitative screening tool.
Fortinet's IV Rank is 37.5%, meaning current implied volatility is higher than 38% of readings over the past 252 trading days. This is in the average range — premiums are neither particularly rich nor cheap.

IV 30d (47.2%) − HV 20d (39.2%) = +8.0pp
Why two RV values? ORATS HV uses 20-day close-to-close. Yang-Zhang uses OHLC. VRP computed with ORATS HV. Δ8.1pp.
HV 20d (39.2%) ÷ IV 30d (47.2%). Below 1.0 = options overpriced.

Fortinet's Volatility Risk Premium (VRP) is +8.0pp. Yes — IV significantly exceeds realized volatility, meaning options are overpriced relative to actual movement. This is the statistical edge premium sellers seek.
Fortinet's IV Rank is 37.5% — meaning current IV is higher than 38% of readings over the past year. This is in the average range — premiums are moderate. Most theta gang traders prefer selling when IV Rank is above 30–50%.
Fortinet's volatility is calculated using the Yang-Zhang estimator, which incorporates overnight gaps, opening range, and intraday movement — more accurate than simple close-to-close calculations for stocks with significant pre/post-market activity. The RV Ratio (0.83) compares realized volatility (HV 20d) to implied volatility (IV 30d). Below 0.85 means actual movement is well below what options are pricing in — favorable for premium sellers.
Fortinet's RV Ratio of 0.83 indicates calming volatility — recent price movement is smaller than the longer-term baseline. When RV is declining but IV hasn't adjusted fully, the gap between them (VRP) widens, benefiting premium sellers. Calming volatility often precedes further IV compression, making current IV levels relatively expensive. This is a favorable environment for selling premium.
