IV Screener: Scanning US Stocks for Implied Volatility Opportunities
The IV Screener is a market-wide scanning tool that filters and ranks every tracked US stock by implied volatility metrics. Instead of checking IV one symbol at a time, you set your parameters — minimum and maximum IV, minimum spread, minimum volume — and the screener returns a sorted list of every stock that matches. This is how professional volatility traders start their day: by identifying which stocks have unusually high or low implied volatility relative to the broader market, then deciding whether to be a buyer or seller of that volatility based on additional analysis.
Implied volatility is not just a number — it is a pricing signal. When IV is extremely high for a stock, option premiums are expensive, which generally favors selling strategies like credit spreads, iron condors, and covered calls. When IV is unusually low, premiums are cheap, which favors buying strategies like long calls, long puts, and debit spreads. The screener lets you find these extremes across the entire market in seconds, turning hours of individual symbol research into a single automated scan.
Understanding the IV Spread Metric
The IV Spread column shows the difference between put IV and call IV for each stock. This is a direct measure of the volatility skew. A large positive spread means puts are significantly more expensive than calls on a volatility basis, indicating strong demand for downside protection. This often occurs before earnings, regulatory decisions, or during broader market stress. A small or negative spread suggests that the market is pricing in more upside risk than downside, which can indicate speculative positioning. Filtering by minimum IV spread helps you find stocks where the skew is extreme and therefore potentially mispriced.
IV Range Filtering
Set the minimum and maximum IV to find stocks in any volatility band. Use low IV ranges like 10-25 percent to find cheap premium candidates. Use high ranges like 60-150 percent to find inflated premiums suitable for selling strategies. This targeted filtering eliminates noise and focuses your attention on actionable names.
Volume and Liquidity Filters
The minimum volume filter ensures you only see stocks with active option markets. Low-volume options carry wide bid-ask spreads that erode your returns through slippage. Setting a meaningful minimum volume threshold like 1,000 contracts keeps your focus on liquid names where you can enter and exit trades efficiently.
Flexible Sorting
Sort by maximum IV to find the most volatile names, by IV spread to find the most skewed names, or by total volume to find the most actively traded options. Each sort reveals a different facet of the market and helps you find different types of opportunities.
Frequently Asked Questions About IV Screening
What IV range is best for selling options?
There is no universal threshold, but many premium sellers focus on stocks with IV above their own historical median. An IV rank above 50 — meaning current IV is higher than half of all readings over the past year — generally indicates elevated premiums that favor selling. Extremely high IV above the 80th percentile is even more favorable but carries additional risk if the elevated volatility is driven by a legitimate upcoming event.
Why filter by minimum volume?
Options with low trading volume often have wide bid-ask spreads that can cost you 5 to 10 percent or more of the option premium just on entry and exit. By filtering for reasonable volume, you ensure that the premiums you see in the screener are actually achievable when you go to trade. High-volume options also tend to have tighter spreads and better fills.
