Options Strategies

Paste into Claude, ChatGPT, or any coding agent

This skill provides a structured decision framework for selecting, analyzing, and managing options strategies across all market conditions. It translates a directional view + volatility outlook into the optimal strategy, quantifies risk via the greeks, and manages positions through expiration or early exit.

When to Use This Skill

  • When the user has a directional or volatility view and wants to express it with options
  • When evaluating whether to buy or sell options (premium payer vs. collector)
  • When analyzing an options chain for a specific stock or ETF
  • When constructing multi-leg strategies (spreads, condors, butterflies)
  • When managing existing options positions (rolling, adjusting, closing)
  • When planning earnings trades with IV expansion/crush dynamics
  • When assessing greeks exposure on a portfolio of options positions
  • When comparing the risk/reward of an options trade vs. stock/futures

What This Skill Does

  1. Strategy Selection: Maps market outlook (direction + volatility + timeframe) to the optimal options strategy
  2. Greeks Analysis: Calculates and interprets delta, gamma, theta, vega, and rho for any position
  3. IV Assessment: Evaluates implied volatility rank/percentile to determine if options are cheap or expensive
  4. Position Construction: Determines strikes, expirations, and leg ratios for multi-leg strategies
  5. Risk Quantification: Calculates max loss, max gain, breakeven points, and probability of profit
  6. Position Management: Provides rolling, adjustment, and early exit decision frameworks
  7. Earnings Play Design: Structures pre-earnings and post-earnings strategies around IV dynamics

Step 3: Greeks Analysis Framework

The greeks measure how an option’s price changes with respect to different variables:

DELTA — Directional Risk
  Definition: $ change in option price per $1 change in underlying
  Range: Calls 0 to +1, Puts 0 to -1
  Key levels:
    ATM options: ~0.50 delta
    Deep ITM:    ~0.90-1.00 delta (behaves like stock)
    Far OTM:     ~0.05-0.10 delta (lottery ticket)
  Portfolio delta: Sum of all position deltas x contract multiplier
  Delta-neutral: Total portfolio delta ~ 0

GAMMA — Acceleration of Delta
  Definition: Rate of change of delta per $1 move in underlying
  Key insight: Gamma is highest for ATM options near expiration
  Risk: Short gamma positions face accelerating losses on large moves
  Gamma risk amplifies in the last 7-14 DTE (days to expiration)
  Management: Close short gamma positions before 14 DTE if possible

THETA — Time Decay
  Definition: $ lost per day from time passage (all else equal)
  Key insight: Theta accelerates as expiration approaches
  Decay curve:
    60-45 DTE: ~1.5% of premium per day
    45-30 DTE: ~2.5% of premium per day
    30-14 DTE: ~4% of premium per day
    14-0 DTE:  ~6-10% of premium per day
  Sellers benefit from theta; buyers fight theta

VEGA — Volatility Sensitivity
  Definition: $ change in option price per 1% change in IV
  Key insight: Longer-dated options have higher vega
  Application:
    High IV → sell options (collect rich premium, benefit from IV contraction)
    Low IV → buy options (cheap premium, benefit from IV expansion)
  Vega is highest for ATM options

RHO — Interest Rate Sensitivity
  Definition: $ change per 1% change in risk-free rate
  Relevance: Minor for short-dated options; matters for LEAPS (>6 months)
  Rising rates: Benefits long calls, hurts long puts

Portfolio Greeks Summary Table:

Position        Delta   Gamma   Theta   Vega
Long call      +       +       -       +
Short call     -       -       +       -
Long put       -       +       -       +
Short put      +       -       +       -
Long stock     +1      0       0       0

Step 4: Implied Volatility Analysis

IV assessment determines whether options are “cheap” or “expensive” relative to history:

IV RANK
  Formula: (Current IV - 52-week Low IV) / (52-week High IV - 52-week Low IV)
  Range: 0% to 100%
  Interpretation:
    0-25%:   LOW IV — options are cheap, favor buying strategies
    25-50%:  BELOW AVERAGE — slight preference for buying
    50-75%:  ABOVE AVERAGE — slight preference for selling
    75-100%: HIGH IV — options are expensive, favor selling strategies

IV PERCENTILE
  Definition: % of days in the past year with IV lower than current IV
  More robust than IV rank (not skewed by single IV spike)
  Interpretation: same directional guidance as IV rank

VOLATILITY SMILE/SKEW
  Definition: IV varies across strikes for the same expiration
  Equity skew: OTM puts have higher IV than OTM calls (crash protection)
  Skew steepness indicates:
    Steep skew: Market pricing high downside risk → bearish sentiment
    Flat skew:  Market complacent about tail risk
  Trading skew:
    Sell expensive skew (OTM puts) via put spreads
    Buy cheap skew (OTM calls) when skew is flat before potential breakouts

TERM STRUCTURE
  Definition: IV across different expirations
  Contango: Near-term IV < far-term IV (normal, stable market)
  Backwardation: Near-term IV > far-term IV (fear, event-driven)
  Calendar spreads profit from contango normalization

Step 5: Strike and Expiration Selection

Strike selection by strategy goal:

GoalStrike SelectionDelta Target
High probability income1-2 standard deviations OTM0.15-0.25 delta
Balanced risk/reward0.5-1 standard deviation OTM0.30-0.40 delta
Directional convictionATM or slightly ITM0.45-0.60 delta
Cheap directional bet1.5-2 standard deviations OTM0.10-0.20 delta
Stock replacementDeep ITM0.70-0.85 delta

Expiration selection guidelines:

PREMIUM SELLERS (theta positive)
  Ideal DTE: 30-45 days
  Rationale: Theta decay accelerates while gamma risk is manageable
  Avoid: <14 DTE (gamma risk too high), >60 DTE (capital tied up too long)

PREMIUM BUYERS (theta negative)
  Ideal DTE: 60-90 days (for swing trades)
  Rationale: Slower time decay, more time for thesis to play out
  LEAPS: 6-12 months for long-term directional views
  Avoid: <30 DTE unless scalping (time decay destroys value)

EARNINGS PLAYS
  Pre-earnings: Enter 7-14 days before, target IV expansion
  Post-earnings: Enter day of, capture IV crush
  Calendar: Sell pre-earnings weekly, buy post-earnings monthly

SPREAD WIDTH
  Vertical spreads: Width = max loss you are willing to accept + credit
  Iron condors: Wing width typically 3-5 strikes ($3-$5 wide per side)
  Butterflies: Wings typically 5-10 points apart depending on price

Step 6: Position Management

When to roll an options position:

ROLLING RULES
  1. ROLL when trade is profitable and you want to extend duration
     - Roll when the short option reaches 50% of max profit
     - Roll to same or further expiration, same or better strike
  2. ROLL when trade is challenged (tested) but thesis intact
     - Roll out in time (further expiration) for additional credit
     - Roll out AND away from the tested side if possible
  3. DO NOT ROLL if:
     - The resulting position has worse risk/reward than a new trade
     - Total credits collected approach max loss (diminishing returns)
     - Underlying thesis has changed
  4. MAXIMUM ROLLS: 2 times per position. After 2 rolls, close and re-evaluate.

PROFIT TARGETS BY STRATEGY
  Iron condors / credit spreads: Close at 50% of max profit
  Short puts / covered calls:    Close at 50-75% of max profit
  Long options:                  Take profits at 50-100% gain on premium
  Straddles / strangles:         Take profits at 25-50% gain (IV expansion)
  Calendars:                     Close at 25-50% gain or when near-term expires

LOSS LIMITS
  General rule: Close at 2x credit received (e.g., received $2.00, close at $4.00 loss)
  Alternatively: Close when the loss equals the width of the spread minus original credit
  Never hold to expiration hoping for recovery — manage mechanically

Adjustment techniques:

IRON CONDOR ADJUSTMENTS
  If put side tested:
    1. Roll put spread down and out for credit
    2. Add a long put below for disaster protection
    3. Close put side, keep call side running (becomes bear call spread)
  If call side tested:
    1. Roll call spread up and out for credit
    2. Close call side, keep put side running (becomes bull put spread)

VERTICAL SPREAD ADJUSTMENTS
  If tested:
    1. Roll entire spread out in time for credit
    2. Widen the spread (accept more risk) for more credit
    3. Add an opposite spread to convert to iron condor

LONG OPTION ADJUSTMENTS
  If profitable:
    1. Sell an OTM option against it (convert to vertical spread, lock in some profit)
    2. Roll up/down to a higher/lower strike, banking some profit
  If losing:
    1. Sell a closer-to-the-money option against it (reduce cost basis)
    2. Roll out in time if thesis is intact
    3. Close and re-enter at better levels

Step 7: Earnings Play Framework

PRE-EARNINGS IV EXPANSION
  Strategy: Buy options 7-14 days before earnings
  Mechanism: IV typically rises 20-50% as earnings approach
  Exit: BEFORE earnings announcement (sell the IV expansion)
  Best with: Straddles, strangles, or calendars
  Risk: Stock moves against you faster than IV rises

POST-EARNINGS IV CRUSH
  Strategy: Sell options just before or at earnings
  Mechanism: IV drops 30-60% after earnings (uncertainty removed)
  Structures: Iron condors, short straddles, short strangles
  Risk: Stock moves more than the expected move (priced in via straddle)

EXPECTED MOVE CALCULATION
  Expected Move = ATM Straddle Price x 0.85
  (or use: Front-month ATM straddle price as approximation)
  Example:
    Stock at $100, ATM straddle costs $8.00
    Expected move: ~$6.80 (+-6.8%)
    Iron condor: sell strikes outside $93.20 and $106.80

EARNINGS PLAY CHECKLIST
  - [ ] Calculate expected move from straddle price
  - [ ] Check historical earnings moves (does stock regularly exceed expected?)
  - [ ] Assess IV rank — is current IV already elevated?
  - [ ] Size position for max loss scenario (stock gaps beyond your strikes)
  - [ ] Plan exit: pre-earnings (IV expansion play) or hold through (IV crush play)
  - [ ] Never risk more than 1-2% of portfolio on a single earnings play

Step 8: Options-Specific Risk Factors

ASSIGNMENT RISK
  American-style options can be exercised early
  Highest risk: Short ITM options near ex-dividend date
  Management: Close or roll short options that go ITM before ex-div
  Spread protection: Long option protects against assignment on short option

PIN RISK
  At expiration, stock hovers near a short strike
  Risk: Uncertain assignment — may or may not be assigned
  Management: Close positions before 3:00 PM ET on expiration day
  Never let short options expire at-the-money

LIQUIDITY RISK
  Wide bid-ask spreads increase cost of entry and exit
  Rules:
    - Bid-ask spread < 10% of option price (liquid enough)
    - Open interest > 100 contracts per strike (minimum)
    - Prefer weekly options on liquid names (SPY, QQQ, AAPL, etc.)
    - Avoid illiquid options on small-cap stocks

EARLY EXERCISE CONSIDERATIONS
  Calls: Rarely exercise early unless deep ITM before ex-dividend
  Puts: May exercise early if deep ITM and time value < interest savings
  Spreads: Assignment on short leg may leave you with naked long — manage immediately

MAX LOSS SCENARIOS
  Always calculate and accept max loss before entering:
    Vertical spread: Width - credit received
    Iron condor: Width of wider side - total credit
    Long option: Premium paid (100% loss possible)
    Naked short: Theoretically unlimited (short calls) or substantial (short puts)
  NEVER sell naked options without understanding and accepting worst-case

Anti-Patterns

DO NOT do these — they are the most common options trading mistakes:

  1. Selling naked options without margin capacity: Naked short calls have unlimited risk. Naked short puts can require buying stock at the strike. Always know your max loss and ensure margin covers worst case.

  2. Buying OTM options as lottery tickets: Far OTM options with <14 DTE have very low probability of profit. Time decay destroys value rapidly. If buying OTM, give yourself 60+ DTE.

  3. Ignoring IV rank when choosing strategy: Buying options when IV rank is >75% means you are overpaying. Selling options when IV rank is <25% means you are collecting thin premium. Match strategy to IV environment.

  4. Holding through earnings without planning: IV crush after earnings can destroy 30-60% of an option’s value overnight. Have a clear pre-earnings vs. post-earnings plan.

  5. Not closing at profit targets: Greed turns winners into losers. Close credit spreads at 50% max profit. The last 50% of profit carries disproportionate risk.

  6. Rolling indefinitely: Rolling a losing position 3, 4, 5 times turns a small loss into a large one. Maximum 2 rolls, then close and re-evaluate.

  7. Trading illiquid options: Wide bid-ask spreads mean you lose money on entry and exit. Stick to options with open interest >100 and tight spreads.

  8. Ignoring position sizing: Options provide leverage. A 100-share equivalent options position on a $200 stock controls $20,000 of stock. Size options trades based on max loss, not premium paid.

Example

User: “AAPL is at $185 and I think it stays range-bound for the next month. IV rank is 72%. What strategy should I use with my $80,000 portfolio?”

Analysis:

## Options Strategy: AAPL Neutral / High IV

### Strategy Selection
- View: Neutral (range-bound)
- IV Rank: 72% (HIGH — favor selling premium)
- Decision Tree: Neutral → High IV → Range-bound → Iron Condor

### Position Construction: Iron Condor
- Sell 175 Put / Buy 170 Put (bull put spread, $5 wide)
- Sell 195 Call / Buy 200 Call (bear call spread, $5 wide)
- Expiration: 35 DTE (optimal theta decay window)
- Credit received: $1.85 (combined)
- Contracts: 2 (based on risk sizing below)

### Risk Metrics
- Max profit: $1.85 x 100 x 2 = $370 (if AAPL stays between $175-$195)
- Max loss: ($5.00 - $1.85) x 100 x 2 = $630 (if AAPL breaks either side)
- Breakeven: $173.15 (lower) / $196.85 (upper)
- Probability of profit: ~68% (based on delta of short strikes)
- Width of range: $175-$195 = $20 (10.8% of stock price)

### Greeks (combined position, 2 contracts)
- Delta: +0.02 (nearly neutral)
- Theta: +$4.20/day (collecting ~$4/day in time decay)
- Vega: -$8.50 (benefits from IV contraction — aligned with high IV rank)
- Gamma: -0.03 (short gamma — risk if stock makes large move)

### Risk Validation (via risk-management)
- Max loss: $630 = 0.79% of $80,000 portfolio (under 2% limit)
- Buying power required: ~$1,000 (margin for one side)
- Portfolio impact: Minimal

### Management Plan
- Profit target: Close at 50% max profit ($0.93 credit to buy back) = ~$185 profit
- Loss limit: Close if loss reaches 2x credit ($3.70 to buy back) = ~$370 loss
- Adjustment: If one side tested, close that side and let the other expire
- Timeline: Close by 14 DTE regardless (avoid gamma risk)
- Earnings check: Confirm no AAPL earnings within 35 DTE window

### Recommendation
APPROVED. Iron condor is well-suited for neutral view + high IV.
Expected return: $185 (50% target) over 17-21 days.
Max risk: $630 (0.79% of portfolio).
