Bear Call Spread — Credit Spread Bearish Với High Probability

Bear Call Spread là chiến lược credit spread ngược với Bull Put Spread. Bạn kiếm premium từ hypothesis rằng stock sẽ không tăng qua một mức. Neutral-to-bearish view, defined risk, theta positive — đây là building block cho income traders và cũng là half của Iron Condor.

Với retail trader Việt, Bear Call Spread là cách an toàn để express bearish view mà không cần short stock hoặc sell naked calls (both extremely risky). Kết hợp với Bull Put Spread, bạn có công cụ neutral income phổ biến nhất trong trading.

Tóm Tắt Nhanh

Bear Call Spread Là Gì?

Bear Call Spread (còn gọi là "Short Call Vertical" hoặc "Credit Call Spread") là 2-leg credit spread:

1. SELL 1 Call tại strike lower (OTM, close to current)
2. BUY 1 Call tại strike higher (further OTM, as protection)

Both calls, same expiration, same stock.

Net credit received. Credit = max profit. Max loss = width - credit.

Logic: Stock ở dưới short strike tại expiration → both calls worthless → bạn giữ credit. Stock tăng cao → max loss nhưng capped.

Cấu Trúc Lệnh

Leg 1: SELL 1 Call (short leg)
       Strike: Lower (OTM, close to current price)
       
Leg 2: BUY 1 Call (long leg)
       Strike: Higher (further OTM, protection)
       
Both: Same expiration, same stock
Result: Net credit

Ví dụ:

Stock: SPY @ $585
Bear call spread (35 DTE):
  SELL 1 SPY 595 Call @ $3.00
  BUY 1 SPY 600 Call @ $1.80
  
Net credit: $3.00 - $1.80 = $1.20
Credit received: $120
Spread width: $600 - $595 = $5
Max profit: $120
Max loss: ($5 - $1.20) × 100 = $380
Collateral: $380

Khi Nào Dùng Bear Call Spread?

Use Case 1 — Range-Bound Stock

Stock trading in a range. Bán calls trên upper resistance, collect premium as stock stays within range.

Use Case 2 — Bearish View, Defined Risk

You expect stock to decline or stay flat, but don't want unlimited loss of short call. Spread provides protection.

Use Case 3 — Resistance Level Trade

Stock approaching key resistance. Bán call spread with short strike at resistance, betting it holds.

Use Case 4 — High IV Capture

When IV is elevated, premiums are rich. Sell credit spreads to capture IV decay.

Use Case 5 — Half of Iron Condor

Combine with Bull Put Spread = Iron Condor = full neutral strategy.

Khi KHÔNG Nên Dùng

• Strong uptrend — fighting the trend
• Low IV — credit too small
• Upcoming catalysts — earnings, FDA, Fed meetings = unexpected moves
• Stock near all-time highs — breakout risk high

Ví Dụ Thực Tế Chi Tiết

Scenario: QQQ @ $495, approaching resistance at $510. You expect pullback.

Setup:
Stock: QQQ @ $495
Thesis: Pullback from resistance, stay below $510
Timeframe: 30 days

Trade:
SELL 1 QQQ 510 Call (30 DTE) @ $4.20
BUY 1 QQQ 515 Call (30 DTE) @ $2.50

Net credit: $4.20 - $2.50 = $1.70
Credit received: $170
Spread width: $5
Max profit: $170
Max loss: ($5 - $1.70) × 100 = $330
Collateral: $330
Probability of profit: ~75%
R/R: $170 / $330 = 0.52:1

4 Outcomes Tại Expiration

Outcome 1 — QQQ @ $500 (Max Profit)

Both calls OTM, expire worthless
Credit kept: $170
Profit: $170 (+52% on collateral)

Max profit at any price ≤ $510.

Outcome 2 — QQQ @ $505 (Max Profit Still)

Both calls OTM, expire worthless
Credit kept: $170
Profit: $170

Outcome 3 — QQQ @ $512 (Partial Loss)

Short 510 Call: $2 intrinsic
Long 515 Call: $0
Net cost to close: $200
Credit: $170
Net loss: $200 - $170 = -$30

Outcome 4 — QQQ @ $520 (Max Loss)

Short 510 Call: $10 intrinsic
Long 515 Call: $5 intrinsic
Net value: $10 - $5 = $5 per spread
Cost to close: $500
Credit: $170
Net loss: $500 - $170 = -$330

Max loss at any price ≥ $515.

Max Profit / Max Loss / Breakeven

Max Profit:

Max Profit = Net Credit × 100

Với QQQ:

Max Profit = $170

Max Loss:

Max Loss = (Width - Net Credit) × 100

Với QQQ:

Max Loss = ($5 - $1.70) × 100 = $330

Breakeven:

Breakeven = Short Strike + Net Credit per share

Với QQQ:

Breakeven = $510 + $1.70 = $511.70

Greeks Behavior

Delta — Âm Nhỏ

• Short call: delta âm (~-0.25)
• Long call: delta dương (~+0.15)
• Net delta: ~-0.10

Slightly bearish, not super directional.

Theta — Dương!

• Short call: theta dương (large)
• Long call: theta âm (smaller)
• Net theta: dương

Time works in your favor — key benefit.

Vega — Âm

• Short call: vega âm
• Long call: vega dương (smaller)
• Net vega: âm

IV decline = profit. Sell when IV high.

Gamma — Âm

Stock moving up through short strike hurts non-linearly. Always gamma risk on short side.

Ưu Điểm

• High probability (65-80% win rate for proper strikes)
• Defined risk — know max loss upfront
• Theta positive — time works for you
• Capital efficient — collateral = width only
• IV harvest — benefits from IV decay
• Part of Iron Condor — building block for more complex strategies

Nhược Điểm

• Asymmetric R/R — risk > reward typically
• Gap risk — overnight moves can blow through strikes
• Unlimited realized loss potential if mismanaged — max should equal width, not more
• Not for strong uptrends — fighting the trend loses
• Complexity — 2 legs require monitoring

Lỗi Người Mới Hay Mắc

Lỗi 1 — Selling Near Support

Selling 510 call when QQQ at $495 and bouncing from support. Direction wrong, lose fast.

Fix: Sell bear call spreads from resistance, not into support bounces.

Lỗi 2 — Strikes Too Close To Money

Short call at $500 when QQQ at $495 = barely OTM. Any small rally → max loss quickly.

Fix: Short strike delta 0.20-0.30 for balance of premium and safety.

Lỗi 3 — Ignore Trend

Uptrend intact, you sell bear call spread "because it's extended." Trends extend longer than you think. Lose.

Fix: Need bearish confirmation — rejection at resistance, break of moving average, momentum divergence.

Lỗi 4 — Hold To Max Loss

"It'll come back." Stock rallies through long strike. Max loss realized.

Fix: Cut at -1.5x credit. Preserve capital to trade again.

Lỗi 5 — Size Too Large

"80% win rate, I'll size up!" One loss erases months. Position sizing always applies, regardless of win rate.

Fix: Max 2% account risk per spread. Don't exceed just because probability feels high.

Exit Management

Profit Taking

• 50% of max credit → consider closing (best R/R)
• 75% of max credit → strong close

Loss Management

• Short strike delta hits 0.50 → consider closing
• Spread value = 1.5x credit → close (preserve capital)

Rolling

• Close current spread, open new one higher/later if thesis still valid
• Only roll once — not infinite rolling

Bear Call Spread vs Short Call

Never sell naked calls as retail. Bear call spread is the safer alternative.
