A Guide to Covered Calls

A Guide to Covered Calls

๐Ÿ“˜ Covered Calls for Beginners

๐Ÿ“Œ Why Utilize the Covered Call Strategy?

  • โœ… Win small and often
  • โœ… Construct low-risk trades
    Goal: Make more money with less risk
  • โš ๏ธ Short-term tax implications
    (Taxed as short-term capital gains)
  • โŒ Avoid prediction-based decisions
    Be conservative, not speculative
  • ๐Ÿ—“๏ธ Sell calls with expiry no more than 45 days out

โŒ Why You Should NOT Sell Naked Puts

  1. Limited upside, but unlimited downside
    This risk asymmetry is dangerous
  2. Poor for consistent cash flow
  3. Assigned to buy stock if price drops below strike
    This only works if you have ample cash and want to own the stock anyway

๐Ÿ’ญ Mindsets to Embrace

  1. Investment vs Speculation
    Stick to strong principles โ†’ higher chance of long-term profit

  2. Lose little, win lots
    Consistently favorable risk/reward setup = long-term edge


๐Ÿงฎ Option Value Basics

Option Value = Intrinsic Value + Time (Extrinsic) Value

  • Intrinsic Value = Value if option is In The Money (ITM)
  • Time Value = Value from time remaining until expiration

Example:

Underlying Stock: $45
| Strike Price | Intrinsic | Time Value | Total Option Value | |โ€”โ€”โ€”โ€”โ€“|โ€”โ€”โ€”โ€”|โ€”โ€”โ€”โ€”-|โ€”โ€”โ€”โ€”โ€”โ€”โ€”| | $50 (OTM) | $0 | $1 | $1 | | $40 (ITM) | $5 | $1.5 | $6.5 |


๐Ÿ“ˆ Key Financial Terms

  • Sharpe Ratio: Risk-adjusted return
  • Alpha: Performance relative to benchmark
  • Beta: Stockโ€™s volatility relative to market

๐Ÿง  Option Greeks (Quick Guide)

Greek Meaning
Delta Price sensitivity of the option to the underlying asset. Also interpreted as the probability of being ITM.
- Call: 0 โ†’ 1
- Put: 0 โ†’ -1
Gamma Rate of change of Delta (how fast Delta moves as stock price changes)
Theta Time decay. Always negative. Highest when ATM.
Implied Volatility (IV) Marketโ€™s expectation of volatility. Higher before events (e.g. earnings).
Choose IV between 30% โ€“ 70%

๐Ÿ” Choosing the Underlying Stock

(Skip if you already own the stock)

  • Pick stocks you are comfortable owning long term
  • Stable, low-beta stocks preferred
  • Avoid earnings or high-volatility events near expiry

๐ŸŽฏ Choosing Strike Prices for Selling Covered Calls

โœ… If youโ€™re okay letting go of your stock:

  • Choose Delta ~ 0.3 โ€“ 0.4
  • Pick an OTM option with a chance to go ITM
    โ†’ Benefit: premium + potential capital gains

โœ… If you want to keep your stock:

  • Choose Delta close to 0
  • Pick a deep OTM option
    โ†’ Lower premium, but higher chance of keeping shares

๐Ÿ—“๏ธ Choosing Expiry Dates

  • Sell options 30โ€“45 days out
    • Time decay (Theta) accelerates within final 30 days
  • Watch out for:
    • Earnings
    • Political events
    • Unexpected volatility spikes

๐Ÿšช Exit Strategy for Covered Calls

๐Ÿ“ Rules of Thumb

  1. The 1% Rule
    • If extrinsic value < 1% of underlying price โ†’ Roll the call
  2. The 2 & 20 Rule
    • If within 2 weeks, the option loses > 80% value โ†’ Buy back, lock in profit
  3. Code Red Rule
    • If the stock crashes unexpectedly โ†’ Sell stock and exit all positions

๐Ÿ”„ By Scenario

Scenario Action
๐Ÿ“ˆ Stock Goes Up Buy back call if you donโ€™t want it called away
๐Ÿ“‰ Stock Drops Buy back for a gain, re-sell a lower strike safer call
โž– Stock Stays Flat Time decay works for you, roll out or resell at lower strike

๐Ÿ’ก The Poor Manโ€™s Covered Call (PMCC)

Also known as: Long Diagonal Spread with Calls

๐Ÿงฑ Structure

  • Buy a long-dated ITM call (LEAP)
    • Expiry > 1 year
    • Delta โ‰ฅ 0.75 (acts like a stock)
  • Sell a short-dated OTM call
    • Similar to covered call premium collection
    • Be careful: If it moves ITM, close the position

๐Ÿ” Diagonal = Mix of:

  • Vertical (same expiry, different strikes)
  • Horizontal (same strike, different expiry)

๐Ÿ“˜ LEAP (Long-Term Equity Anticipation Securities)

  • Options with > 1 year expiration
  • Behaves like synthetic long stock (with less capital)
  • Strong time value protection
  • Look for Delta โ‰ฅ 0.75

๐Ÿ“Œ Extra Rules of Thumb

  • Short-term volatility can create buying opportunities for option sellers
  • Avoid selling too close to IV spikes (e.g. earnings, Fed meetings)
