Every options trader has faced this: you spot a trend, position accordingly, and yet—your P&L looks nothing like the chart.
Why? Because volatility isn’t symmetrical.
Markets don’t price calls and puts with equal logic when fear or greed spikes. This asymmetry—what I call Implied Volatility Anisotropy—can open up strategies that both directional and volatility traders often miss.
Let’s unpack it without the jargon overload.
📈 Volatility Usually Follows the Trend (But Not Always)
Normally, volatility and trend move together:
-
Uptrend → call options get pricier (IV rises).
-
Downtrend → put options get pricier (IV rises).
Simple enough. But markets are never that polite. Sometimes you get:
-
A rising market with rising put IV (bearish undercurrent).
-
A falling market with rising call IV (bullish squeeze pressure).
This mismatch is where the anisotropy edge lives.
💡 The Core Logic of the Strategy
-
Rising volatility in an uptrend:
-
Normally bullish.
-
But if put IV also rises, the market is mispricing risk.
-
✅ Strategy: Sell puts at inflated IV.
-
If the trend continues upward → you gain from delta.
-
If the trend stalls → put IV collapses, you gain from vega.
-
-
-
Falling volatility in a downtrend:
-
Normally bearish.
-
But if call IV rises while price falls, sentiment is distorted.
-
✅ Strategy: Sell calls at inflated IV.
-
If the downtrend continues → you gain from delta.
-
If the downtrend slows → call IV collapses, you gain from vega.
-
-
In short: you sell the “wrongly” inflated side of the volatility curve.
⚠️ Why It’s Harder Today
This used to be easier when markets were less efficient. Today:
-
Bearish uptrends are rare (everyone’s algos sniff them out).
-
Bullish downtrends don’t last long before short-covering kicks in.
-
Pricing models adapt faster, leaving fewer “fat-fingered” volatility mispricings.
Still, if you’re patient, these setups appear in crisis moments—flash crashes, macro events, or liquidity squeezes.
🛠️ A Pragmatic Way to Trade It
If timing the anisotropy feels too advanced, here’s the practical play:
-
Run a volatility-selling overlay on top of your directional trades.
-
Don’t just trade “price goes up, I buy calls.” Instead:
-
When long, check if put IV is suspiciously high → sell puts.
-
When short, check if call IV is suspiciously high → sell calls.
-
It’s volatility timing stacked on top of directional timing.
👉 Downsides? Sharpe ratio isn’t amazing.
👉 Upside? Over the long run, this approach is very hard to kill.
🎯 Final Takeaway
Options traders often obsess over delta (direction) or vega (volatility). The anisotropy strategy shows you can win on both fronts—if you’re sharp enough to notice when the market’s fear and greed are misaligned.
Is it easy? No. Is it bulletproof? Definitely not.
But if you can tolerate volatility and think in probabilities, this approach adds a subtle but powerful edge to your options toolkit.
Because in the end, trading isn’t about being right—it’s about spotting when the market is wrong.
