Diagonal Spread — Directional Play Với Time Component

Diagonal Spread là strategy kết hợp calendar spread (different expirations) với vertical spread (different strikes). Nó cho bạn directional exposure với time component — tốt cho swing traders muốn hold positions qua nhiều tuần mà vẫn có theta protection.

Diagonal spreads là building block cho nhiều advanced strategies, bao gồm Poor Man's Covered Call (PMCC) — một trong những chiến lược được LEAPS traders yêu thích nhất.

Tóm Tắt Nhanh

Diagonal Spread Là Gì?

Bullish Diagonal Call Spread (most common):

1. BUY 1 Call long-dated, lower strike (ITM or ATM)
2. SELL 1 Call short-dated, higher strike (OTM)

Both calls, same stock, but different strikes AND different expirations.

Net debit (long leg more expensive). Bullish directional bias with theta harvesting from short leg.

Cấu Trúc Lệnh

Bullish Diagonal Call:
  Leg 1: BUY 1 Long-dated Call (ITM, 60-90 DTE)
  Leg 2: SELL 1 Short-dated Call (OTM, 20-30 DTE)
  Result: Net debit

Bearish Diagonal Put:
  Leg 1: BUY 1 Long-dated Put (ITM, 60-90 DTE)
  Leg 2: SELL 1 Short-dated Put (OTM, 20-30 DTE)
  Result: Net debit

Ví dụ (Bullish):

Stock: NVDA @ $180
Bullish diagonal call spread:

BUY 1 NVDA 170 Call (90 DTE) @ $18.00
SELL 1 NVDA 190 Call (30 DTE) @ $2.50

Net debit: $18 - $2.50 = $15.50
Total cost: $1,550

Khi Nào Dùng Diagonal Spread?

Use Case 1 — Poor Man's Covered Call (PMCC)

Alternative to owning 100 shares + selling call. Use deep ITM LEAPS as stock substitute, sell near-term OTM calls for income.

Use Case 2 — Directional Swing Trade

Bullish view over 1-3 months. Diagonal gives directional exposure while earning premium from short leg.

Use Case 3 — Income on Existing LEAPS

You own LEAPS options. Sell monthly short-dated calls against them to generate income.

Use Case 4 — Reduced Cost Directional

Cheaper than naked long calls due to credit from short leg. Better R/R for moderate bullish views.

Khi KHÔNG Nên Dùng

• Very uncertain direction — calendars better for pure neutral
• Short timeframe — diagonals need time to work
• High IV on long leg — overpaying for long leg
• No defined management plan — complex to manage

Ví Dụ Thực Tế: Poor Man's Covered Call

Scenario: You want bullish exposure to AAPL over 3 months with income generation. AAPL @ $210.

Setup:
Stock: AAPL @ $210
View: Moderate bullish, 3-month timeframe

Traditional Covered Call approach:
  Buy 100 AAPL shares: $21,000
  Sell 1 AAPL 220 Call (30 DTE) @ $2.50

Poor Man's Covered Call (Diagonal):
  BUY 1 AAPL 180 Call (180 DTE) @ $32.00 (deep ITM)
  SELL 1 AAPL 220 Call (30 DTE) @ $2.50
  
  Net debit: $32 - $2.50 = $29.50
  Total cost: $2,950

Capital required:
  Traditional: $21,000
  PMCC: $2,950 (86% less capital!)

Management of PMCC

Month 1 (Short Leg 30 DTE)

AAPL @ $215 (slightly up)
Long 180 Call: now ~$36 (intrinsic $35 + extrinsic)
Short 220 Call: ~$0.80 (OTM, theta decay)

Action: Buy back short call for ~$0.80
Profit: $1.70 from short call (67% of initial credit)

Month 2 (Roll to Next Short Leg)

AAPL @ $220
Long 180 Call: ~$42
Sell new 230 Call (30 DTE) @ $2.80

Net position:
  Long leg cost: $32 (was)
  Credits collected so far: $2.50 + $2.80 = $5.30
  Effective cost: $26.70

Month 3 (Continue Rolling)

AAPL @ $225
Previous short 230 Call: $0 (expired)
Long 180 Call: ~$46

Sell new 235 Call @ $2.50
  
Credits so far: $5.30 + $2.50 = $7.80
Effective long leg cost: $24.20

End of 6 Months

AAPL @ $235
Long 180 Call: $55 (worth)
Total credits from 6 short legs: ~$14

Profit: ($55 - $32) + $14 = $37 per spread
Return on $2,950 = 125% in 6 months

(Compare to buying stock at $21,000: profit ~$2,500 = 12% return)

PMCC vs Traditional Covered Call

PMCC is capital-efficient alternative to covered calls, but doesn't capture dividends.

Max Profit / Max Loss / Breakeven

Complex due to time component.

Max Profit (approximate):

Max Profit ≈ (Short Strike - Long Strike) + Short Premium - Debit

Assumes closing at short expiration with stock at short strike

Max Loss:

Max Loss = Net Debit (approximately)

Occurs if stock drops significantly

Breakeven: Hard to calculate precisely due to time decay.

Greeks Behavior

Delta — Positive (Bullish)

Long leg ITM: delta ~0.80-0.90 Short leg OTM: delta ~-0.20 to -0.30 Net delta: ~0.50-0.70 (bullish)

Theta — Positive Initially

Short leg decays faster than long leg → positive theta.

Vega — Positive

Long leg has higher vega than short leg.

Gamma — Dynamic

Changes significantly as stock moves and time passes.

Ưu Điểm

• Capital efficient (especially PMCC)
• Defined risk — max loss = debit
• Directional exposure
• Theta positive
• Vega positive
• Flexible management — roll short leg monthly
• Income generation from short legs

Nhược Điểm

• Complex management
• Assignment risk on short leg
• Directional risk — wrong direction = loss
• LEAPS illiquid sometimes
• Commission for frequent rolls
• Doesn't capture dividends

Lỗi Người Mới Hay Mắc

Lỗi 1 — Choosing Wrong LEAPS Strike

Selecting OTM LEAPS = high delta sensitivity, high risk. Selecting too ITM = expensive, low leverage.

Fix: Use 70-80 delta LEAPS (moderately ITM). Balance of leverage and safety.

Lỗi 2 — Not Rolling Short Leg

Letting short leg expire ITM → assignment → stuck with short stock position.

Fix: Always roll short leg before expiration if ITM.

Lỗi 3 — Wrong Direction

Bearish trade in bullish market = expensive lesson.

Fix: Confirm trend before diagonal trades. Use technical analysis.

Lỗi 4 — Selling Short Leg Too Aggressive

Short strike too close → frequent assignment threats, limiting upside.

Fix: Short leg OTM at delta 0.25-0.35 for balance.

Lỗi 5 — Ignoring Volatility Changes

IV crush on long leg destroys position value.

Fix: Enter diagonals when IV is low. Avoid buying LEAPS when VIX elevated.

Exit Management

Scenario 1 — Stock Moves Toward Target

Close entire position or roll short leg higher for more credit.

Scenario 2 — Stock Stalls

Roll short leg forward, collect more premium, extend trade.

Scenario 3 — Stock Drops

Evaluate: is long leg still valuable? Close if thesis broken.

Scenario 4 — Approaching Long Leg Expiration (LEAPS)

Consider rolling to new LEAPS or exiting entirely.

Pre-Trade Checklist

☐ Clear directional view?
☐ Long leg ITM (delta 0.70-0.80)?
☐ Short leg OTM (delta 0.25-0.35)?
☐ 2-3x expiration ratio?
☐ Plan for rolling short leg?
☐ Max loss = debit acceptable?
☐ Not in trending against direction?
