Spread
A spread is when you buy one option and sell another option (same underlying stock, usually same expiration, different strikes) to reduce your cost and cap your risk. Instead of buying an expensive $3 call outright, you might buy the $100 call and sell the $105 call for a net cost of $1.50.
Spreads are the most popular strategy among professional traders because they offer defined risk, lower capital requirements, and high probability of profit. Retail traders often ignore them, paying full price for naked calls and puts—and losing because of it.
The Core Idea: Buy to Open, Sell to Close (Or Vice Versa)
Simple example:
- Stock XYZ at $100
- You think it will rally to $105, but you can't afford a $3 call
- Buy $100 call for $3
- Sell $105 call for $1
- Net cost: $2
Payoff at expiration:
- If XYZ at $110: You profit $5 on the long call (buy at 100, sell at 105 via the short call). Max profit = $5 − $2 = $3 per share = $300
- If XYZ at $100: Both calls expire worthless, you lose $2 per share = $200
- If XYZ at $102: Long call worth $2, short call worth $0. You profit $2 − $2 = $0. Breakeven.
Defined risk: Your max loss is $200 (the debit you paid). Your max profit is $300 (the width of strikes minus cost).
Compare to buying the call naked:
- Buy $100 call for $3, lose $3 if stock doesn't move = $300 loss
- With spread, buy $100 call for $3, sell $105 call for $1, lose only $2 = $200 loss
The spread saved you $100 in max loss, at the cost of capping your max profit at $300 instead of unlimited.
Types of Spreads: The Main Four
1. Bull Call Spread (Bullish, Lower Risk)
You're moderately bullish. You want to buy a call but reduce the cost.
Setup:
- Buy call at $100 strike (lower strike, more expensive)
- Sell call at $105 strike (higher strike, cheaper)
- Net cost: Buy $3, sell $1 = $2 debit
Profit:
- Max profit: $5 width − $2 cost = $3 per share ($300 on one contract)
- Max loss: $2 per share ($200)
- Breakeven: $100 + $2 = $102
Win rate: ~55−60% (higher than naked calls)
When to use: Moderately bullish outlook, want to reduce capital at risk.
2. Bear Call Spread (Moderately Bearish, Income)
You think stock will stay flat or decline. You want to collect premium but cap your risk.
Setup:
- Sell call at $100 strike (collect fat premium, collect $3)
- Buy call at $105 strike (cap your loss, pay $1)
- Net credit: $3 − $1 = $2 credit
Profit:
- Max profit: $2 per share ($200) — you keep the credit if stock stays below $100
- Max loss: $5 width − $2 credit = $3 per share ($300)
- Breakeven: $100 + $2 = $102
Win rate: ~60−65% (stock just has to stay below $102)
When to use: Stock near resistance, expect flat/down move, want to harvest premium with defined risk.
3. Bull Put Spread (Bullish, Income-Focused)
You're moderately bullish. You want to collect premium from selling puts, but cap your downside risk.
Setup:
- Sell put at $95 strike (collect premium, collect $2.50)
- Buy put at $90 strike (cap your loss, pay $0.75)
- Net credit: $2.50 − $0.75 = $1.75 credit
Profit:
- Max profit: $1.75 per share ($175) if stock stays above $95
- Max loss: $5 width − $1.75 credit = $3.25 per share ($325)
- Breakeven: $95 − $1.75 = $93.25
Win rate: ~65−70% (stock just has to stay above $93.25)
When to use: Bullish outlook, want to collect income from puts, don't have enough cash for cash-secured puts.
4. Bear Put Spread (Moderately Bearish, Income)
You're moderately bearish. You want to profit if stock declines, but cap your risk.
Setup:
- Buy put at $95 strike (pay $2.50)
- Sell put at $90 strike (collect $0.75)
- Net debit: $2.50 − $0.75 = $1.75
Profit:
- Max profit: $1.75 per share ($175) if stock stays above $90
- Max loss: $5 width − $1.75 cost = $3.25 per share ($325)
- Breakeven: $90 + $1.75 = $91.75
Win rate: ~60% (stock has to stay above $91.75)
When to use: Bearish on stock, want defined-risk bet, expect it to drop but not crash.
Spreads vs Naked Options: The Risk Comparison
| Max Risk | Max Profit | Win Rate | Capital Needed |
|---|
| Buy naked call | Unlimited | Unlimited | ~40% | Full debit |
| Bull call spread | Capped | Capped | ~55% | Lower debit |
| Sell naked call | Unlimited | Limited | ~60% | 20%+ margin |
| Bear call spread | Capped | Capped | ~60% | Lower margin |
| Sell naked put | Capped | Limited | ~65% | Cash reserve |
| Bull put spread | Capped | Capped | ~65% | Lower cash |
Key insight: Spreads have lower win rates than naked puts (65% vs 70%), but they require far less capital and have defined risk. For consistent profits, spreads are superior.
The IV Crush Protection: Why Spreads Save You on Earnings
Remember IV crush? Spreads protect you:
Earnings play — Naked call:
- Buy $100 call for $3, collect $0.30 vega gain pre-earnings
- Stock rallies $5, but IV crushes 45%, lose $1.35 to vega
- Net: gain $1.25, loss $1.35 = −$0.10, breakeven
Earnings play — Bull call spread:
- Buy $100 call for $3, sell $110 call for $0.75, net cost $2.25
- Stock rallies $5, IV crushes 45%
- Long call: +$1.25 delta, −$0.90 vega = +$0.35
- Short call: −$0.40 delta, +$0.36 vega = −$0.04
- Net: +$0.35 − $0.04 = +$0.31 profit
- You profit because your short call (positive vega) offsets the long call's vega loss
Spreads protect you from vega crush. This is a huge advantage on earnings trades.
Real-World Example: Tesla Bull Call Spread
TSLA at $250. You think it'll hit $270 in 60 days.
Naked call approach:
- Buy $250 call for $15
- If it rallies to $270: profit $20 − $15 = $5, 33% return
- If it stays at $250: lose $15, −100% loss
- Capital at risk: $1,500
Bull call spread approach:
- Buy $250 call for $15
- Sell $270 call for $5
- Net cost: $10
- If it rallies to $270+: profit $20 − $10 = $10, 100% return
- If it stays at $250: lose $10, −100% loss (on lower capital)
- Capital at risk: $1,000
The spread has:
- 67% of the max profit upside ($10 vs $15)
- 33% less capital at risk ($1,000 vs $1,500)
- Better risk-reward ratio (risk $1k to make $1k vs risk $1.5k to make $0.5k)
- Less damage from IV crush on earnings
When Spreads Are Better Than Naked Options
Spreads win when:
- You're slightly directional but uncertain: Bull call spread (moderately bullish, not 100% sure)
- Earnings are coming: Short spread protects you from vega crush
- You have limited capital: Lower cost entry, lower capital requirement
- You want consistent small wins: 65−70% win rate on spreads vs 40−50% on naked
- You're generating income: Sell spreads instead of naked options, keep premium with less risk
Naked options win when:
- You have high conviction: Stock WILL rally 20%+, buy naked calls for unlimited upside
- You can afford it: Capital isn't constrained
- IV crush won't hurt: Buying premium early (low IV), not near earnings
- You're scaling professionally: Large capital base handles unlimited risk
Managing Spreads: Exit Rules
Most profitable trades exit before expiration:
Bull call spread at $100 strike: If stock rallies to $108 (80% of max profit territory), close it
- Lock in $0.80 profit on $2.25 cost = 35% gain in 2 weeks
- Don't wait for $270 (full max profit), because gamma risk increases
Bear call spread: If stock drops to $92 (half your max profit), close it
- Don't wait for $90 expiration; take the win early
Early exits are the professional way. Waiting for expiration to extract the last $0.05 is greedy and exposes you to gamma risk.
Key Takeaways
- Spread: buy one option, sell another at different strike
- Defined risk: max loss and max profit known upfront
- Lower capital: spreads cost less than naked options (buy call cheaper than sell call naked)
- Higher win rate: spreads 60−70% win rate vs naked 40−50%
- IV crush protection: short leg offsets long leg's vega loss
- Bull call / bull put: for bullish outlook
- Bear call / bear put: for bearish outlook
- Exit early: lock in 50−80% of max profit, don't wait for expiration
