VERTICAL SPREADS

Core Concept: Buy and sell options at different strikes (same expiration) to reduce cost and define risk on both sides.

Why It Matters

Spreads are more capital-efficient than single options, with capped risk and reward. Core strategy for consistent income and directional bets.

When to Use

Use vertical spreads when:

  • Want directional exposure with less capital
  • Defined risk on both sides
  • IV rank >50% (sell expensive, buy cheaper)
  • High probability trades (70-80% win rate)

Avoid when:

  • Expecting huge move (unlimited upside better)
  • IV rank < 25% (poor risk/reward)
  • Liquidity poor (wide spreads)

Spread Types

Bull call spread: Buy lower strike call, sell higher strike call (debit)
Bear put spread: Buy higher strike put, sell lower strike put (debit)
Bull put spread: Sell higher strike put, buy lower strike put (credit)
Bear call spread: Sell lower strike call, buy higher strike call (credit)

Debit spreads: Pay to enter, profit from directional move
Credit spreads: Collect to enter, profit from theta + no move against you

Trade-offs

Pros: Lower cost, defined risk, better win rate than naked options
Cons: Capped profit, requires two trades (commissions), less liquid

Vertical spreads combine long_call and long_put with short options to reduce cost and capture options_greeks theta.

Strike selection formula:

  • Sell at 0.30-0.40 delta (70% OTM probability)
  • Buy 5-10 strikes further OTM (protection)
  • Target credit: 1/3 of spread width

Position sizing: Risk 1-2% of account per trade
Example: $50k account → Max $500-1,000 risk per spread

Examples

EXAMPLE

Bull put spread (credit spread):

Stock: $105 (bullish outlook)
Sell: 100 Put for $2.50 (0.35 delta)
Buy: 95 Put for $1.00 (protection)
Net credit: $1.50 ($150 per spread)
Width: $5 ($500)

Max profit: $150 (if stock stays above $100)
Max loss: $350 ($500 - $150)
Breakeven: $98.50 ($100 - $1.50)
Risk/reward: 2.3:1 (need 70% win rate)

Outcome 1: Stock at $105+ at expiration

  • Both options expire worthless
  • Keep $150 (30% return on $350 risk)

Outcome 2: Stock at $97 (below breakeven)

  • Max loss: $350
  • Put spread executed: Forced to buy at $100, sell at $95

Bear call spread (credit spread):

Stock: $100 (bearish outlook)
Sell: 105 Call for $2.00
Buy: 110 Call for $0.75
Net credit: $1.25 ($125)
Width: $5

Max profit: $125 (stock below $105)
Max loss: $375 ($500 - $125)
Breakeven: $106.25

Outcome: Stock stays at $100

  • Keep $125 (33% ROI in 45 days)

Bull call spread vs long call:

Bullish on stock at $100, 45 DTE

Option A: Buy 100 Call for $5.00

  • Cost: $500
  • Max profit: Unlimited
  • Max loss: $500
  • Breakeven: $105

Option B: Buy 100 Call ($5), Sell 110 Call ($2)

  • Cost: $300 (40% cheaper)
  • Max profit: $700 (at $110+)
  • Max loss: $300 (40% less risk)
  • Breakeven: $103 (better)

Trade-off: Capped at 233% gain vs unlimited, but better risk/reward.

Managing winners:

Entry: Bull put spread, 45 DTE, $150 credit

Day 30: Captured 50% profit ($75)

  • Option 1: Close early (take $75, free up capital)
  • Option 2: Hold for full $150 (risk reversal)

Rule: Close at 50% profit to reduce risk and redeploy capital.

Managing losers:

Entry: Bear call spread, max loss $350

Position down $175 (50% max loss):

  • Option 1: Close and take loss (avoid max loss)
  • Option 2: Roll up and out (extend time, higher strikes)

Rolling: Sell 105/110 at loss, buy 110/115 spread for same or small credit

Adjusting for earnings:

Stock at $100, earnings in 2 weeks:

Before earnings: IV 80%, 100/95 put spread collecting $2.00
After earnings: IV drops to 40%, spread worth $0.50
Close early: $150 profit (75% max) in 2 weeks vs 45 days

High IV events = faster profits from volatility crush. ```
