Earnings season is the most tempting time to sell credit spreads. Implied volatility is sky-high, premiums are fat, and IV crush after the announcement can make your spread profitable overnight. But the gap risk is real. Let's break this down honestly.

Why Earnings Premiums Are So Large

Before a stock reports earnings, implied volatility spikes because nobody knows what the numbers will be. The options market prices in an "expected move" — the amount the stock might move in either direction after the announcement.

Example: AAPL earnings, stock at $195.

  • IV before earnings: 45% (normally 22%)
  • Expected move: ±$8 (about 4%)
  • $185 put (normally worth $1.50): Now worth $4.50
  • Credit on a $185/$180 put spread: $2.80 (normally $1.30)

    • That $2.80 credit on a $5-wide spread is a 56% credit-to-width ratio. Normally you'd get 25-30%. The premium is more than double.

    The IV Crush Advantage

    After earnings are announced, IV collapses back to normal levels (known as IV crush). If the stock doesn't move much, your spread's value drops dramatically.

    If AAPL reports and stays at $195:

  • IV drops from 45% to 24% overnight
  • Your $185/$180 spread that was worth $2.80 before earnings might be worth $0.80 after
  • You close for $0.80, keeping $2.00 profit ($200 per contract)
  • That's a 71% return on $2.20 risk — in one day

    • This is the bull case for earnings credit spreads. When it works, it's incredible.

    The Gap Risk Problem

    Here's the other side. AAPL misses earnings and guides lower. The stock gaps down 8% to $179.

  • Your $185 put is now deep in the money
  • Your $180 put is also in the money
  • The spread is worth nearly $5.00
  • You lose $2.20 ($5.00 - $2.80 credit) per contract — that's max loss

    • One bad earnings trade can erase 2-3 weeks of winning credit spreads. And earnings gaps are not rare — approximately 30-40% of S&P 500 companies move more than the expected move each quarter.

    When Earnings Spreads Make Sense

    On stocks that historically don't move much on earnings. Some companies are boring reporters — their stocks move 2-3% max. Think utilities, staples, and mature tech companies. The market still prices in a big move, but the actual move is small.

    When the expected move is exaggerated. If AAPL's options are pricing in an 8% move but the stock has moved more than 5% on earnings only once in the past two years, the market might be overpricing the risk.

    Short put spreads below the expected move. Place your short strike below the lower bound of the expected move.

    Example: AAPL expected move is ±$8 ($187-$203 range).

  • Sell the $183 put (below the expected move's lower bound)
  • Buy the $178 put
  • Credit: $1.80 on $5 width

    • You're betting that AAPL won't drop more than the market already expects. This happens roughly 70% of the time by definition (expected moves are ~1 standard deviation).

    When to Avoid Earnings Spreads

    First earnings after an IPO or major event. No historical data to gauge typical moves. The stock could move 20%.

    High-growth stocks with binary outcomes. NVDA reporting when the market is debating whether AI revenue will double or stall. The move could be massive in either direction.

    When you'd be oversized. If a single earnings spread would represent more than 3-5% of your account at risk, the potential loss isn't worth the premium.

    When the stock has a history of massive gaps. Some stocks routinely move 10-15% on earnings. The premium is large because the risk is large. You're not getting a free lunch.

    The Strangle-Width Approach

    An advanced technique: sell a credit spread where the short strike is 1.5× the expected move away.

    If AAPL's expected move is $8:

  • 1.5 × $8 = $12
  • Short put at $195 - $12 = $183
  • Buy $178 put
  • Credit: ~$1.20

    • You're giving up some premium compared to selling at the expected move boundary, but your probability of profit jumps to roughly 85-90%. The IV crush still works in your favor even though you collected less.

    Post-Earnings Strategy: Sell the Crush

    A safer approach is to wait until AFTER earnings and sell spreads on the ensuing IV collapse.

    After AAPL reports and IV drops from 45% to 24%, premiums normalize. But if the stock drops 4% on earnings and you're bullish on recovery, selling a put spread the day after earnings captures:

  • Reasonable premium (not as high as pre-earnings, but still decent)
  • Zero gap risk (the event is over)
  • Potential stock recovery as an additional tailwind

    • This is less exciting but significantly lower risk.

    Tracking Earnings Spread Performance

    Separate your earnings trades from your regular credit spread trades in your tracking. Over a year, calculate the P&L of earnings spreads independently. Many traders find that earnings spreads have higher variance and lower risk-adjusted returns than non-earnings spreads, despite the attractive premiums.

    OptionsPilot flags upcoming earnings dates for any stocks in your watchlist, so you can make a deliberate decision about whether to hold, close, or specifically enter a position around the announcement.
