Short Volatility

Short volatility means selling options to profit from lack of movement and time decay. Short selling stock means borrowing and selling shares to profit from price decrease. They're completely different strategies with different risk profiles.

Yes, with naked short positions (straddles, strangles), you can lose much more than the premium collected - potentially unlimited on call side. With defined risk (iron condors), your max loss is capped at wing width minus credit.

Naked positions collect more premium (no protection cost) and have higher probability of profit. Experienced traders use them with strict position sizing and management. However, most retail traders should use defined risk structures.

With defined risk (iron condor), your loss is capped at max loss - the wings protect you. With naked positions, a large gap can cause losses far exceeding your collected premium. This is why position sizing and defined risk are so important.

Short volatility typically has a 70-85% win rate depending on strike selection. However, winning trades are small (premium collected) while losing trades can be large. Success depends on managing losers, not just having high win rate.

Generally no - earnings can cause large moves that hurt short vol positions. Either exit before earnings, or intentionally sell into earnings (requires accepting event risk). Many traders specifically avoid earnings with short vol.

Common range is 0.16-0.30 delta. Lower delta (0.10-0.16) = higher win rate, lower premium, wider breakevens. Higher delta (0.25-0.30) = lower win rate, higher premium, tighter breakevens. 0.16 is popular as it's roughly 1 standard deviation.

Consider rolling when: (1) Stock is approaching your short strike, (2) You can collect credit or small debit to roll, (3) Your thesis (range-bound) is still valid. Roll to later expiration and/or wider strike. If thesis is broken, consider closing instead.

Iron condor: Wider profit zone, lower credit. Good when expecting stock to stay in range but uncertain where. Iron butterfly: Narrower profit zone, higher credit. Good when expecting stock to pin near specific price. Iron condor is more common for income trading.

Keep max loss per position to 2-5% of portfolio. Limit total short vol exposure to 15-30% of portfolio. Diversify across sectors but remember correlation increases in crashes. Don't concentrate too much in correlated assets.

Implement a rules-based system: (1) Enter at high IV Rank (>50), (2) Use consistent DTE (30-45), (3) Use consistent delta for short strikes, (4) Exit at 50% profit or 200% loss or 21 DTE, (5) Trade diversified underlyings consistently. Over time, you capture the average VRP.

Professional market makers do, but for retail it's often not practical due to commissions and complexity. Alternative approach: Hedge at discrete thresholds (e.g., when delta reaches ±0.30) rather than continuously. Or accept some delta risk and keep positions small.

Calculate: (1) Portfolio vega × potential IV spike (e.g., 20 point VIX spike), (2) Portfolio gamma × potential stock move (e.g., 10% move), (3) Combined scenario. Ensure losses in stress scenario don't exceed your risk tolerance. Reduce size or add hedges if too exposed.

Depends on account size and management capacity. Generally 3-10 positions across different underlyings/expirations provides diversification while remaining manageable. More positions = more diversification but more to manage. Balance based on your situation.

Common approaches: (1) Allocate 5-15% of short vol profits to buying cheap OTM puts, (2) Use VIX call spreads (in US), (3) Reduce position size during high-risk periods. Goal is to have something that profits dramatically in crashes to offset short vol losses. Accept lower overall returns for crash protection.
