You sold a covered call, collected premium, and now it's worth less than you sold it for. Should you close early and take profits, or wait until expiration? Here's how to decide.

The 50% Rule Explained

The most popular rule: Close your covered call when you've captured 50% of the maximum profit.

Example:

  • Sold call for $2.00 premium
  • Call is now worth $1.00
  • You've captured $1.00 (50% of max)
  • Close and move on

    • Why 50%? Research shows the risk/reward after 50% profit favors closing:

  • You've captured most of the easy money
  • Remaining $1.00 could take weeks to decay
  • Frees up capital for new positions
  • Reduces assignment risk

    • Other Profit-Taking Thresholds

    Conservative: 25-30%

  • Close earlier, trade more frequently
  • Lower profit per trade, but more trades
  • Less time at risk

    • Aggressive: 75%

  • Wait for more profit
  • Fewer trades, more profit each
  • More time at risk

    • Optimal: 50-65%

  • Balanced approach
  • Good profit capture with reasonable risk
  • Most research supports this range

    • When to Close Based on Time

    Days to Expiration (DTE) Guidelines:

    0-7 DTE: Consider closing if profitable. Gamma risk increases.

    7-14 DTE: If 50%+ profit, definitely close. Theta decay slows.

    14-21 DTE: Good time to roll to next cycle if taking profits.

    21-45 DTE: Monitor the 50% threshold. Time is on your side.

    Situations to Close Early Regardless of Profit

    1. Earnings Announcement Coming IV crush after earnings can erase gains. Close before earnings if you've hit your profit target.

    2. Major News Event Fed meetings, product launches, regulatory decisions - close before high-impact events.

    3. Stock Breaks Key Technical Level If support breaks, stock could fall quickly. Close the call to free up shares for potential sale.

    4. Your Thesis Changed If you no longer want to own the stock, close everything.

    When NOT to Close Early

  • You've only captured 10-20% and have 30+ DTE
  • The stock is trending toward your strike (potential for max profit)
  • You want the shares called away anyway
  • Transaction costs would eat into profits

    • The Math Behind Early Closing

    Scenario A: Wait for full profit

  • Sell call for $2.00
  • Wait 30 days, expires worthless
  • Profit: $2.00 over 30 days = 6.67% monthly

    • Scenario B: Close at 50%

  • Sell call for $2.00
  • Close after 10 days for $1.00
  • Profit: $1.00 over 10 days
  • Sell new call for $1.80
  • Combined: $2.80 over 30 days = 9.33% monthly

    • Closing early and re-entering often beats waiting!
