Q

Covered Call (Formula)

A

Covered Call = Long Asset + Short Call

Payoff:
1) OTM: Gain = Limited to Premium
2) ITM: Loss will occur

Motivation:
- Yield enhancement if OTM
- Reduce LONG ASSET position
- Get P&L @ expiration

Q

Portfolio Covered Call Value (Formula)

A

Long Covered Call Perspective:

Portfolio Value = (St - Value of Call)
Value of Call = Max [(S-X), 0]

Q

Covered Call P&L (Formula and Rationale)

A

ITM Gain P&L = [(X-S0) + C0]

OTM Gain P&L = [Δ Asset Value + C0]

Rationale:

Always gain C0 as sold call
Gains ΔSt if OTM due to long asset
Gains (X-S0) because I locked sell @ X

Q

Protective Put & Portfolio Value (Formula)

A

Protective Put = Long Stock + Buy Put

Long Protective Put Value = St + Value Put
Value Put = Max [(X-St), 0]

Rationale: Limit losses

Q

Bull Spread (Concept)

A

Position Gain: ↑ Asset Prices

Position:
1) Sell Call @ High = Cheap
2) Buy Call @ Low = Expensive

17
Q

Bull Spread Payoff (Formula)

A

Long Bull Maximum Payoff = (X High - X low) + (C High - C Low)

18
Q

Bear Spread (Concept)

A

Position Gain: ↓ Asset Prices = ↑ Gains

1) Buy Put @ High = Expensive
2) Sell Put @ Low = Cheap

19
Q

Bear Spread Payoff (Formula)

A

Long Bear Spread Payoff = (X High - X Low) - (P High + P Low)

20
Q

Straddle (Concept, Example & Payoff)

A

1) Long Straddle = Buy Call + Buy Put @ X = Long Vol
2) Format: V-shape

Example:
Xc = 2.29 = Long Call @ S + 2.29
Xp = 2.28 = Long Put @ S - 2.28
Σ = 4.57
∴ V-Shape is formed @ (Xc + Xp)

Payoff:
If St > (Xc + Xp) = CALL ITM = (S1-X) - C0 - P0
If St < (Xc + Xp): PUT ITM = (X-S1) - C0 - P0

21
Q

Collar (3 Formulas)

A
  1. Collar = Long Stock + Short Call @ X High + Long Put @ X Low
  2. Collar = Covered Call + Long Put
  3. Collar = Protective Put + Short Call
22
Q

Collar (Concept & Format)

A

Concept: Sacrifices upside potential to lock losses

Format: Escadinha tradicional c/ minimum profit

23
Q

Zero Cost Collar (Concept)

A

Payoff from (+C0) premium and (-P0) premiums cancel each other

24
Q

Collar Gain

A

a. If St > XH = Short Call ITM
a. Gain A = [(XH-S0) +C0 -P0]
a. Reason: Locked sell @X High

b. If XH > St > XL = Nothing ITM
b. Gain B = [(St-S0) +C0 - P0]
b. Reason: Get Δ Prices

c. If St < XL = Buy Call ITM
c. Gain C = [(XL-S0) + C0 - P0]

25
Q

Calendar Spreads (Long and Short)

A

Long Cal Spread = Sell Near + Buy Long
Short Cal Spread = Buy Near + Sell Long

26
Q

Calendar Spreads (Concept)

A

Theta Play. Possible to get Theta Positive.

27
Q

Volatilty Types (List)

A

Historical: Observable
Implicit: Derived from Option Pricing Model and Derivatives traded in the market

28
Q

Volatility Skew (Concept)

A

Volatility is more steeper for Puts @ Low Strikes

Rationale: Pessimists buy more downside protection than optimists = ↑ Put Prices = ↑ Vol Puts OTM

Tip: ↑ Steeper = Bull Market

29
Q

Volatility Smile (Concept)

A

U-Shaped. OTM Calls and OTM Puts are more volatile because they are overpriced.

30
Q

Risk Reversal Strategy (Description)

A

Long Risk Reversal = Asset Price will ↑

Buy OTM Call @ X High = Underpriced
Sell OTM Put @ X Low = Overpriced
