Options Trading During Earnings Season
Earnings season—the four-to-six-week period each quarter when most publicly traded companies report results—is the Super Bowl of options trading. Individual stock IV surges before the announcement, moves of 5-15% occur overnight, and IV collapses the next morning. This cycle creates repeatable opportunities for options traders who understand the mechanics.
The Earnings IV Cycle
Pre-Earnings Buildup (T-14 to T-1)
As the earnings date approaches, implied volatility on the reporting stock increases steadily. Traders buy options to speculate on the move or hedge existing positions. Market makers raise prices to compensate for the upcoming event risk.
Typical IV increase: 20-50% above normal levels by the day before the announcement.
The Announcement (T-0)
The company reports after the close or before the open. The stock gaps based on the results, guidance, and market reaction. Average earnings move: 4-8% for large caps, 8-15% for mid and small caps.
Post-Earnings IV Crush (T+1)
Regardless of the stock's direction, IV collapses the next morning. This "IV crush" is the most reliable pattern in earnings options trading.
Typical IV crush: 30-60% decline in IV within 24 hours of the announcement.
Pre-Earnings Strategies
1. Selling Iron Condors Before Earnings
Sell an iron condor that expires shortly after the earnings date. The elevated pre-earnings IV means you collect outsized premium.
Why it works: The market's "expected move" (priced into the straddle) overestimates the actual move about 70% of the time. The stock usually moves less than the options market predicted.
Setup:
Risk: The other 30% of the time, the stock moves more than expected. Position size accordingly—no more than 2% of your account per earnings trade.
2. Selling Strangles (Advanced)
For larger accounts with margin capacity, selling a strangle captures even more premium. The risk is undefined, so sizing must be conservative.
3. Calendar Spreads
Sell the weekly option (high IV) and buy the monthly option at the same strike. The weekly option carries most of the earnings premium and will decay rapidly after the announcement, while the monthly retains value.
Directional Earnings Plays
Buying Straddles Before the IV Buildup (T-14 to T-7)
Buy a straddle before the pre-earnings IV buildup begins. As IV expands into the earnings date, the straddle gains value from vega expansion—potentially allowing you to sell before the announcement at a profit without needing a large move.
Key timing: Enter 2-3 weeks before earnings, exit 1-2 days before the announcement. You're trading the IV expansion, not the earnings move itself.
Buying Debit Spreads for Direction
If you have a directional view on earnings, buy a debit spread (bull call spread for bullish, bear put spread for bearish). The spread structure reduces the IV crush impact because both legs lose IV roughly equally.
Advantage over buying naked calls/puts: The IV crush hits both legs, so the spread value is more dependent on direction than on IV changes.
Post-Earnings Strategies
1. Selling Puts on Post-Earnings Dips
When a stock drops 5-10% on earnings but the results are actually decent (maybe guidance was slightly below expectations), the overreaction creates an opportunity. IV is still elevated the morning after, meaning put premiums are fat.
Sell cash-secured puts at a price where you'd want to own the stock. The combination of the post-earnings dip and elevated premium creates a very attractive entry.
2. Buying the "Earnings Drift"
Research shows that stocks tend to drift in the direction of their earnings surprise for 2-6 weeks after the announcement. If a stock beats expectations significantly and gaps up, buying a call spread for the following month captures this drift.
3. Selling Covered Calls on Post-Earnings Rally
If you own a stock that just reported strong earnings and gapped up, the remaining elevated IV makes covered calls especially lucrative. Sell calls above the gap-up level to capture premium while the IV normalizes.
The Expected Move Calculation
Before every earnings trade, calculate the expected move:
Expected move = ATM straddle price × 0.85
This approximation tells you how much the options market thinks the stock will move. If SPY's ATM straddle costs $10.00, the expected move is approximately $8.50 (or about 1.5% at SPY 550).
For individual stocks, the expected move can be 5-15% or more, depending on historical earnings volatility.

Common Mistakes
Buying naked calls or puts before earnings. Even if you're right on direction, the IV crush can destroy your position. A stock can go up 5% and your call still loses money if IV drops enough.
Trading every earnings event. Focus on stocks with the most favorable setups (high IV percentile, clear expected moves, liquid options). Quality over quantity.
Ignoring the expected move. If your iron condor's short strikes are inside the expected move, you're taking on too much risk for the premium collected.
