# IV and HV: Using Volatility to Select Better Wheel Trades

By Adrian Rosebrock · Last updated May 14, 2026 · 17 min read

Let's suppose that gold miner stock, `IAG`, currently has an IV of 55%.

Is that high? Low? Worth selling into?

You literally cannot answer that question without knowing what `IAG` actually _did_ historically.

**IV and HV together tell you whether the market is overpricing or underpricing a stock's expected movement. That gap is what determines whether selling premium is worth it or not.** 

A 55% IV on `IAG` means nothing in isolation. 

But 55% IV against a 35% HV? Now you have context. Now you have a trade decision.

If you've read the [Implied Volatility](https://wheelmetrics.io/blog/what-is-implied-volatility/) and [Historical Volatility](https://wheelmetrics.io/blog/what-is-historical-volatility/) articles, you know what each number measures individually:

- IV is the market's forecast of future movement (priced into premiums right now) 
- HV is what the stock actually did over a past period (calculated from real price data)

The trick is using them _together_ to decide whether a trade is worth taking.

I run this IV and HV framework before every Wheel trade. 

Let's dive in.

## What Does the Gap Between IV and HV Tell You?

Let's again consider `IAG` and assume it has a current IV of 55%.

Is 55% IV high?

Low?

Worth selling into?

**As I alluded to in the intro of this article, you cannot answer that without context.** The raw IV number is meaningless on its own. What matters is the _gap_ between IV and HV, because that gap tells you whether the market's forecast is overshooting or undershooting the stock's historical reality.

**When IV is greater than HV**, the market expects more movement than the stock has historically shown. This movement may _potentially_ favorable for sellers, but ask _why_ before jumping in. Elevated IV can imply options are overpriced relative to historical reality (i.e., an opportunity for premium sellers like us).

**When IV is less than HV**, the market expects _less_ movement than the stock has historically shown. You're not being adequately compensated for the actual movement the stock tends to make. This situation is unfavorable for sellers.

### IV Crush and the Gap

When IV is significantly above HV, that gap tends to collapse over time. IV mean-reverts back toward HV.

This is the connection to IV crush: 

- The IV/HV gap gives you a way to gauge how much crush potential exists
- The bigger the gap (IV above HV), the more room IV has to compress, and the more extrinsic value evaporates from the options you sold

**That compression is money in your pocket for Wheel traders.**

### Worked Example With IAG

| Scenario | IV | HV (20-day) | Gap (IV - HV) | What It Means for Sellers |
|----------|-----|-------------|----------------|---------------------------|
| IV > HV | 55% | 35% | +20 | Market overpricing movement vs. historical reality (favorable, but investigate why) |
| IV < HV | 25% | 40% | -15 | Market underpricing movement vs. historical reality (thin premiums, elevated real risk) |

Let's look at two hypothetical scenarios with `IAG` (IAMGOLD) to see how the IV/HV gap can change our trading strategy:

- **Scenario 1:** `IAG` at IV 55% / 20-day HV 35%
    - IV is pricing in significantly more movement than `IAG` has shown historically
    - Gap of +20 points
    - Favorable for sellers (with due diligence on _why_ IV is elevated)
- **Scenario 2:** `IAG` at IV 25% / 20-day HV 40%
    - IV is pricing in _less_ movement than `IAG` has actually been making
    - Gap of -15 points
    - Unfavorable for sellers, premiums are thin relative to the stock's actual behavior

Same stock. Completely different trade decisions. The gap made the call.

## What Are IV Rank and IV Percentile?

![Percent sign](https://wheelmetrics.io/blog/implied-vs-historical-volatility/percent.jpg)

The IV/HV gap tells you whether IV is high relative to recent movement.

But is IV high relative to _itself_? 

Different question. 

That's what IV Rank and IV Percentile answer:

- 50% IV on a gold miner like `IAG` might be elevated 
- 50% IV on a volatile biotech might be _below average_ 

The raw number tells you nothing without knowing what's normal for _this specific stock_.

### IV Rank vs. IV Percentile

| Metric | What It Measures | Sensitive To | Best For |
|--------|------------------|--------------|----------|
| IV Rank | Where IV sits in its 52-week range | Extreme highs and lows (one spike can skew the range) | Quick "is IV elevated?" check |
| IV Percentile | What % of days had lower IV | The full distribution of IV over the year | More reliable read on whether today's IV is genuinely unusual |

Here's a quick (and simplified) breakdown on IV Rank vs. IV Percentile:

- **IV Rank:** Where current IV falls between the stock's 52-week high and low IV on a scale of 0-100. High rank means IV is near the top of its recent range.
- **IV Percentile:** Addresses what percentage of trading days in the past year had IV _lower_ than today. Also on scale of 0-100. High percentile implies IV is higher than it's been on most days.

IV Rank and IV Percentile measure different things and can give different readings on the same stock.

### How IV Rank and IV Percentile They Can Diverge

Imagine `IAG` had a single massive IV spike to 90% six months ago during a company-specific event, but IV otherwise ranged between 30-50%.

Now suppose the current IV is at 48%, while the 52-week IV range had a low of 28% and high of 90%.

Running the numbers:

- **IV Rank:** (Current IV - 52-week Low) / (52-week High - 52-week Low) = (48% - 28%) / (90% - 28%) = 20 / 62 = 32%. Looks moderate because that single spike to 90% stretched the top of the range, making 48% appear mid-range.
- **IV Percentile:** If IV normally sat between 30-50% and only breached 48% during that one brief spike, then 48% is higher than roughly 80% of trading days. IV Percentile reads 80%. _Actually elevated._

Same stock, same moment, two different readings. IV Percentile caught what IV Rank missed because a single spike distorted the rank.

### Practical Thresholds

Here are my suggested starting points for IV Rank and IV Percentile (both use a 0-100 scale):

- **Above 50:** Elevated, worth looking at for selling premium
- **Above 70:** Rich premium territory
- **Below 30:** Thin premiums, consider waiting for a better entry

**These are guidelines, not rules.** A stock with an IV Rank of 45 but a strong IV/HV gap might still be a good trade. Use these _alongside_ the gap, not instead of it.

### The Practical Approximation

The problem here is that _many_ (if not most) retail platforms _do not_ show IV Rank or IV Percentile directly.

But there _is_ an easy way around that.

**My favorite approximation is to compare current HV across multiple timeframes (1-month, 3-month, 1-year).** 

If 1M HV is significantly above 3M and 1Y HV, the stock is in a heightened volatility regime. Similar signal to a high IV Rank, no specialized tools required.

*This is the approach we use in the real-world examples later.** And the best part is, as long as you have access to a stock's historical closing prices, you can easily compute the HV.

## How to Combine IV and HV for Better Trade Decisions

Now we put it all together.

### The IV/HV Decision Flowchart

Here's the flowchart we'll be following through the rest of this section:

```
Start
  │
  ▼
Is IV > HV? ── No ──► SKIP
  │
 Yes
  │
  ▼
Is 1M HV elevated vs. 3M/1Y? ── No ──► WAIT
  │
 Yes
  │
  ▼
Why is IV elevated?
  │
  ├─ Routine catalyst ──► SELL
  │
  └─ Company red flag ──► SKIP
```

Bookmark this page and keep it handy for when you are analyzing Wheel setups.

#### Step 1: Check the IV/HV Gap

Start by asking if IV is above HV:

- **IV significantly > HV:** Favorable. Proceed to Step 2.
- **IV roughly equal to HV:** Caution. Premium looks fat but the stock is actually moving this much historically. Proceed to Step 2 with tighter criteria.
- **IV < HV: STOP.** You're being _underpaid_ for the actual movement. Skip this trade.

#### Step 2: Gauge Whether Volatility Is Elevated

Now you need to compare HV across timeframes (1M vs. 3M vs. 1Y). Is the stock in a heightened regime, or is this business as usual?

- **1M HV significantly above 3M/1Y:** Elevated regime. IV is likely inflated too. Good crush potential. Proceed to Step 3.
- **1M HV in line with 3M/1Y:** Business as usual. Premiums may be adequate but no special edge. Proceed cautiously.
- **1M HV below 3M/1Y:** Quiet period. Premiums are likely thin. Consider waiting.

#### Step 3: Investigate WHY IV Is Elevated

- **Routine catalyst** (earnings uncertainty, sector rotation, general market fear): Acceptable. Sell premium if you'd own the stock at the strike price.
- **Company-specific red flag** (fraud, bankruptcy risk, regulatory action): **STOP.** High IV is justified by existential risk. Walk away.

**This flowchart produces three outputs: sell, wait, or skip.** 

### Four Quadrants of IV and HV (With Examples)

| Quadrant | IV | HV | Gap | Verdict |
|----------|-----|----|-----|---------|
| **The Sweet Spot** | High | Low | IV >> HV | Sell option (with due diligence) |
| **Justified IV** | High | High | IV ≈ HV | Cautious sell (be careful) |
| **The Desert** | Low | Low | IV ≈ HV | Wait, premiums too thin |
| **The Trap** | Low | High | IV << HV | Skip, you're being underpaid |

Each combination of high/low IV and HV creates a distinct setup. Here's how to read them, using `IAG` as the running example:

#### 1. The Sweet Spot: High IV / Low HV

- `IAG` at IV 55% / 20-day HV 35%
- Market overpricing movement relative to historical reality
- Best setup for selling premium, with rich premiums and room for IV to crush back toward HV
- This is the "sell" signal (after due diligence)

#### 2. Justified IV: High IV / High HV

- `IAG` at IV 55% / 20-day HV 52%
- IV is high, but the stock is actually moving that much historically
- Fat premium reflects genuine risk, not mispricing
- Proceed with caution: tighter strike selection, smaller position sizing

#### 3. The Desert: Low IV / Low HV

- `IAG` at IV 25% / 20-day HV 22%
- Calm stock, calm market pricing
- Premiums are too thin to typically justify the capital commitment and opportunity cost
- Wait for volatility to expand before selling

#### 4. The Trap: Low IV / High HV

- `IAG` at IV 25% / 20-day HV 40%
- Market underpricing actual historical movement
- **Worst setup for sellers.** You're collecting a small premium while the stock's actual movement can easily overwhelm it
- Skip entirely

If you can only memorize one row, make it The Trap. That's where the expensive lessons live.

### The Pre-Trade Volatility Checklist

**Run this before every Wheel trade (it takes 60 seconds:)**

1. **IV/HV Gap check:** Is IV above HV? (Positive gap = favorable, negative gap = skip)
2. **Gap magnitude check:** How big is the gap? (Bigger gap = more edge and crush potential)
3. **HV regime check:** Compare 1M HV vs. 3M and 1Y HV. Is volatility elevated or business as usual?
4. **"Why?" check:** Why is IV elevated? (Routine catalyst = acceptable, company-specific danger = walk away)

Don't shoot yourself in the foot. Take sixty seconds and answer these questions _before_ you open a position.

## Applying the Framework to Real Mining Stock Trades

We've been using `IAG` as our running example. Now let's expand to four gold mining stocks: `CDE`, `IAG`, `SSRM`, and `NEM`.

Same sector. Same macro exposure. Very different volatility profiles.

### The Macro Backdrop

The [Iran war](https://en.wikipedia.org/wiki/2026_Iran_war) (which started around February 28, 2026) spiked oil past $100/barrel, reigniting inflation fears. The Fed held rates at approximately 3.5-3.75% and revised its dot plot to just one cut in 2026.

Gold initially surged to an all-time high (approximately $5,246) on safe-haven demand, then sold off roughly 6% as rising yields and a stronger dollar outweighed geopolitical risk. Gold mining stocks gave back their 2026 gains.

This is the backdrop driving the volatility shifts in the chart below.

![2x2 grid showing 1-month, 3-month, and 1-year historical volatility for NEM, CDE, SSRM, and IAG from March 2025 to March 2026](https://wheelmetrics.io/blog/implied-vs-historical-volatility/mining-stocks-hv.png)

### What the Chart Reveals

All four stocks show a sharp 1M HV spike in late February and early March 2026. That's the Iran war effect hitting the entire gold mining sector simultaneously.

But the _magnitude_ of each stock's reaction and its _pre-war baseline_ are what make the volatility stories different.

**`CDE`** is the "always volatile" archetype. 1M HV regularly spikes to 0.8-1.0 throughout the year (June '25, September '25, November '25), and those are `CDE`-specific swings, _not_ macro events. The Iran war spike to approximately 0.85 on 1M HV barely stands out against `CDE`'s normal behavior. 3M HV sits around 0.75, 1Y HV around 0.72. **Elevated HV is `CDE`'s baseline.**

**`IAG`** shows a stock-specific spike to approximately 0.85 on 1M HV in August-September '25 (unrelated to the Iran war), then settled back. The Iran war pushed 1M HV to approximately 0.9. 3M HV sits around 0.6, 1Y HV around 0.55. A moderate baseline with occasional spikes.

**`SSRM`** was calm for most of the year, with 1M HV hovering around 0.4-0.6. Then the Iran war hit and 1M HV _exploded_ to approximately 0.95, the largest spike on the chart. This is the "regime change" example: a stock that was quiet suddenly becoming the most volatile in the group. 3M HV sits around 0.8, 1Y HV around 0.58.

**`NEM`** is the steadiest of the four. Earlier fluctuations were mild. The Iran war pushed 1M HV to approximately 0.7, elevated for `NEM` but still the lowest spike of the group. 3M HV sits around 0.55, 1Y HV around 0.42.

### Running the Checklist on Each Stock

_**Note:** The HV values below come directly from the chart. IV values are illustrative but realistic for gold miners in this environment. They are not exact market quotes._

#### IAG

- 1M HV ~0.9 (Iran war spike), 3M HV ~0.6, 1Y HV ~0.55
- HV regime: clearly elevated (1M >> 3M >> 1Y)
- If IV is running around 65-70%, IV is below 1M HV but _above_ 3M and 1Y HV
- The gap to 1M HV is narrower than `SSRM`'s, and IV comfortably exceeds `IAG`'s longer-term baselines — so this leans more "Justified IV" than "Trap"
- The Iran war is a known macro catalyst, not a company-specific red flag
- **Verdict: cautious sell if you'd own `IAG` at the strike** — tighter strikes and smaller sizing are appropriate given IV still trails 1M HV

#### CDE

- 1M HV ~0.85, 3M HV ~0.75, 1Y HV ~0.72
- HV regime: only slightly elevated (1M above 3M/1Y, but not dramatically... `CDE` always runs hot)
- If IV is ~75%, it's roughly in line with 3M HV. No real gap to exploit
- **Verdict: no special edge — skip unless you specifically want `CDE` exposure**

#### SSRM

- 1M HV ~0.95, 3M HV ~0.8, 1Y HV ~0.58
- HV regime: _dramatically_ elevated (1M is nearly 2x the 1Y HV, the biggest regime shift of the group)
- If IV is ~70%, 1M HV > IV. The stock is moving _more_ than the market prices in
- Yes, IV at 70% is above the 1Y HV of 58%, which _looks_ attractive. But the framework checks IV against _recent_ HV first, and right now `SSRM` is whipping around more than premiums compensate for. That's "The Trap," not "The Sweet Spot."
- **Verdict: skip or wait.** Once the Iran war spike fades and 1M HV settles back toward the 58% baseline, _then_ 70% IV against ~58% HV becomes The Sweet Spot. But not yet.

#### NEM

- 1M HV ~0.7, 3M HV ~0.65, 1Y HV ~0.42
- HV regime: elevated (1M above 3M, both above 1Y)
- If IV is ~55%, IV is below 1M HV. IV hasn't fully caught up to the recent spike
- `NEM`'s steady nature means premiums will remain moderate even in elevated periods
- **Verdict: wait for the HV spike to settle, then revisit**

### The Takeaway

Same sector. Same macro backdrop. Four completely different volatility stories:

- `CDE` barely noticed the Iran war (it's _always_ volatile)
- `SSRM` was transformed by it (regime change)
- `IAG` and `NEM` fell somewhere in between

**That's why you need the framework, not just _"Is IV high?"_**

If you just checked raw IV on all four, you might have sold puts on every single one. The framework separated the cautious sell (`IAG`) from the skip (`CDE`, `SSRM`) from the wait (`NEM`).

**That kind of filtering is worth 60 seconds of your time.**

## Common Volatility Mistakes When Selecting Wheel Trades

These four volatility mistakes sit alongside the broader [Common Options Trading Mistakes to Avoid for The Wheel Strategy](https://wheelmetrics.io/blog/options-trading-mistakes-wheel-strategy/).

Here are four mistakes I consistently see with options traders running The Wheel.

### 1. Selling Puts Just Because IV Is High

- High IV alone tells you nothing. If HV is just as high, the market isn't overpricing anything.
- `CDE`'s IV looks juicy, but HV is right there with it. You're not getting an edge, you're getting compensated for real risk.
- Always check the gap before assuming fat premium equals opportunity.

### 2. Ignoring the HV Regime

- `CDE` at 75% IV sounds high, but if HV has ranged from 60% to 100% over the past year, you're selling into business-as-usual territory. That's fine if you can find a strike you'd like to own CDE at, but typically this should make you cautious.
- Compare 1M vs. 3M vs. 1Y HV to see whether the stock is genuinely in an elevated regime or just being itself.

### 3. Over-Relying on One Metric

- Each metric tells you one piece of the story, _none_ of them give you the full picture by themselves.
- The framework exists because you need the IV level, HV across timeframes, the gap between them, _and_ the "why" behind the elevation.
- `NEM` might look boring on IV alone, but the full framework tells you whether it's a wait or a skip.

### 4. Confusing the IV/HV Gap Direction

- IV < HV means the market is pricing in _less_ movement than historical reality. You're being underpaid.
- **Sellers want IV > HV:** The market overpricing movement relative to what the stock has actually done.
- If `IAG`'s IV drops below HV after a volatile period settles, that's a signal to wait, not sell.

## Where to Go from Here

IV and HV together give you context that neither provides alone:

- The gap tells you whether the market is overpricing or underpricing movement. 
- The HV regime tells you whether volatility is elevated or normal
- And the "why" check keeps you from walking into traps

**Run the checklist before every trade.** It takes 60 seconds and saves you from trades that look good on the surface but aren't.

Most of your edge comes from the trades you _don't_ take. The discipline to say _"Not this one"_ is what separates consistent income from random premium collection.

## Frequently Asked Questions

**What is the difference between implied volatility and historical volatility?**

Implied volatility (IV) is the market's forecast of how much a stock will move in the future. IV is priced into option premiums right now. Historical volatility (HV) measures how much the stock actually moved over a past period. IV is forward-looking and market-derived; HV is backward-looking and calculated from real price data.

**How do you use IV and HV together to select options trades?**

Compare IV to HV to determine whether the market is overpricing or underpricing a stock's movement. (1) Check if IV is above HV (favorable gap for sellers), (2) compare HV across timeframes (1M, 3M, 1Y) to gauge whether volatility is elevated, and (3) investigate why IV is elevated before selling.

**What does it mean when IV is higher than HV?**

When IV is higher than HV, the market is pricing in more movement than the stock has historically shown. This can be favorable for option sellers because premiums may be inflated relative to the stock's actual behavior, but you should investigate why before assuming it's an opportunity.

**What does it mean when IV is lower than HV?**

When IV is lower than HV, the market is pricing in less movement than the stock has actually been making. This is unfavorable for option sellers — you're collecting thin premiums while the stock's real movement can easily overwhelm them. Skip the trade.

**What is IV Rank and how does it differ from IV Percentile?**

IV Rank measures where current IV falls between a stock's 52-week high and low IV on a 0-100 scale. IV Percentile measures what percentage of trading days in the past year had lower IV than today.

**How do you know if a stock's volatility is elevated?**

Compare historical volatility across multiple timeframes. If 1-month HV is significantly above 3-month and 1-year HV, the stock is in a heightened volatility regime. This is a practical approximation that works even when your platform doesn't show IV Rank or IV Percentile.

**What is the best IV/HV setup for selling options premium?**

The best setup is high IV combined with low HV, sometimes called 'The Sweet Spot.' The market is overpricing movement relative to historical reality, premiums are rich, and there's room for IV to crush back toward HV. Always confirm the elevated IV isn't driven by a company or sector-specific red flag before selling.

**Should you sell puts when IV equals HV?**

When IV roughly equals HV, proceed with caution. The premium may look attractive, but the stock is actually moving as much as the market expects. There's no special edge from mispricing — you're being fairly compensated for real risk, not overpaid. Tighter strikes and smaller sizing are appropriate.

**How do you check if high IV is justified before selling options?**

Ask why IV is elevated. Routine catalysts like earnings uncertainty, sector rotation, or general market fear are acceptable reasons. Sell if you'd own the stock at the strike. Company-specific red flags like fraud allegations, bankruptcy risk, or regulatory action mean the high IV is justified by existential danger. Walk away.

**What is IV crush and how does the IV/HV gap relate to it?**

IV crush is the rapid collapse of implied volatility, often after a catalyst like earnings passes. The IV/HV gap helps you gauge crush potential. The bigger the gap where IV exceeds HV, the more room IV has to compress back toward historical levels. That compression accelerates the decay of extrinsic value in options you've sold.
