Straddle Before Earnings: Strategy Explained

Summary

A long straddle before earnings is a bet that the stock will move more than the options market expects. You buy both an ATM call and an ATM put, paying peak IV prices, and need a move large enough to overcome IV crush. It is a high-risk, high-reward play that works best on stocks with a history of surprises.

NFLX is trading at $680 before its Q3 report. The ATM straddle (buy the $680 call and $680 put) costs $45, or about 6.6% of the stock price. That means Netflix needs to move more than $45 in either direction for you to profit.

Over the past 8 quarters, NFLX has moved an average of 10.2% after earnings. The straddle is pricing in 6.6%. The math suggests the straddle has a positive expected value on this specific name.

How the Trade Works

Setup:

  • Buy 1 ATM call
  • Buy 1 ATM put
  • Same strike, same expiration (the weekly that includes the earnings date)

    • Maximum loss: The total premium paid (both legs)

    Breakeven points:

  • Upside: Strike + total premium
  • Downside: Strike - total premium

    • Profit scenario: The stock moves beyond either breakeven point.

    The IV Crush Problem

    Here is why most earnings straddles lose money. When you buy the straddle, you are buying at peak IV. The morning after earnings, IV collapses 40-50%. Your options lose a massive chunk of value from vega alone.

    Example on AAPL:

    You buy the $190 straddle for $8.00. After earnings, Apple beats estimates and the stock opens at $195 (+2.6%).

  • The $190 call should be worth ~$5.00 (intrinsic) + time value
  • But IV dropped from 38% to 22%
  • The call opens at $6.20 instead of the expected $7.50
  • The $190 put is worth $0.30 (nearly worthless)
  • Total value: $6.50 vs $8.00 paid = $1.50 loss per share

    • You were right on direction by 2.6% and still lost money. The 2.6% move was not enough to overcome the 42% IV crush.

    When Straddles Actually Work

    Straddles work when the stock moves substantially more than the expected move. You need the move to be 1.5x-2x the straddle price to make meaningful money.

    Winning example on META:

    META is at $490. Straddle costs $32 (6.5% expected move). Meta reports incredible AI revenue growth and the stock gaps to $545 (+11.2%).

  • The $490 call is worth $55 (intrinsic) + minimal time value = ~$56
  • The $490 put is worth ~$0.10
  • Total value: $56.10 vs $32.00 paid = $24.10 profit per share (75% return)

    • The 11.2% move was 1.7x the expected move. That is the sweet spot.

    Stock Selection Criteria

    Look for stocks where historical earnings moves consistently exceed the expected move:

  • NFLX: Average actual move 10-12% vs typical expected move of 7-8%
  • TSLA: Average actual move 8-10% vs typical expected move of 6-7%
  • SNAP: Average actual move 15-20% vs typical expected move of 12-14%

    • Avoid straddles on stocks where the actual move consistently falls short:

  • MSFT: Average actual move 3-4% vs expected move of 4-5%
  • AAPL: Average actual move 3-5% vs expected move of 4-6%
  • JNJ: Average actual move 2-3% vs expected move of 3-4%

    • Timing the Entry

    Worst time to buy: The day of earnings. IV is at its absolute peak.

    Better time to buy: 5-7 days before earnings. IV is elevated but not at peak. You capture some of the IV run-up as a bonus before the event.

    Best approach: Buy 7-10 days before earnings, set a profit target of 20-30% on the straddle from the IV run-up alone, and close before the announcement. You avoid IV crush entirely and still profit from the volatility expansion.
