Should You Close Your Covered Call at 50% Profit?

You sold a covered call two weeks ago for $4.00. The stock drifted sideways, time decay did its work, and now the option is worth $1.80. You've captured 55% of the maximum profit with half the time still remaining.

Do you hold for the last 45%, or close it and move on?

Most experienced covered call sellers will tell you the same thing: close it. The reason comes down to how time decay works — and how a position's risk profile shifts as expiration approaches.

Why the Last 50% Isn't Worth the Wait

The first half of a covered call's profit arrives relatively quickly. Time decay accelerates as expiration approaches, but the risk profile also shifts. Here's the problem with holding past 50%:

The profit curve flattens while the risk stays constant. You collected $2.20 of profit in 14 days. The remaining $1.80 could take another 14-21 days — and during that entire stretch, the stock could rally past your strike, earnings could surprise, or a market-wide move could push the option back up. You're accepting the same risk for diminishing reward.

Your capital is locked. Those 100 shares can't be used for a new covered call while the current one is open — you're committing them to collect the last, slowest sliver of premium on this position while its tail risk keeps running. Closing frees them to start a fresh cycle sooner; whether that nets more premium over a year isn't established, but it does cap this position's risk.

A winning trade can become a losing one. A stock that's been flat for two weeks can gap sharply in the third week — on earnings, macro news, or sector rotation. Closing while you're ahead removes that risk entirely.

The Math: Closing Early vs. Holding to Expiration

Here's a concrete comparison. Say you sell 12 covered calls per year, each for roughly $4.00 per contract, holding to expiration every time:

• 12 trades x $4.00 = $4,800 in maximum annual premium (assuming every option expires worthless — which they won't)

Now compare: closing at 50% profit frees up your shares to sell a new call sooner. Whether that produces more premium over a full year is not established — the studies most cited for the 50% rule used index cash-secured puts, not individual-stock covered calls, and the results don't transfer directly. What IS clear: each position carries significantly less tail risk, and you eliminate the specific scenario where a winning trade reverses sharply in the final days while you wait for diminishing returns.

The practical reality: not every held-to-expiration trade stays profitable. Some reverse. Some get assigned at inconvenient moments. Closing early reduces those risks, at the cost of leaving some premium on the table.

Many systematic covered call sellers target the 40-60% range rather than a hard 50%. The principle matters more than the precise number: capture the bulk of the profit in less time, then reset.

When Closing Early Matters Most

Not every position needs to be closed early. The 50% rule matters most in these situations:

Earnings approaching. If the underlying stock reports earnings before your option expires and you're already sitting on a healthy profit, close before the binary event. Earnings can move a stock 5-15% overnight, turning a comfortable winner into an assignment or a loss.

High-IV names. Volatile stocks like NVDA or TSLA can erase weeks of time decay in a single session. Taking profits early on high-IV positions is a risk management move, not just an income optimization move.

Multiple positions open. If you're managing 5-10 covered calls simultaneously, closing the profitable ones early reduces your attention burden and lets you focus on the positions that need active management.

Late in the expiration cycle. Gamma risk — the tendency for options to swing sharply in value near expiration — increases in the final days. Closing a few days before expiration avoids the whipsaw.

When It's Fine to Hold

There are cases where holding past 50% makes sense:

Very low-delta, far out-of-the-money positions. If the stock would need to rally 10%+ to reach your strike and there's only a week left, the remaining premium is small and the risk of reversal is minimal. Letting it expire worthless is fine.

You want assignment. If the stock has rallied to a price where you'd be happy selling anyway, there's no reason to close early. Let assignment happen — you sold at your target price plus kept the premium.

How to Actually Close a Covered Call Early

Closing a covered call means buying back the same option you sold. This is called "buy to close" (BTC):

1. Find the same option contract in your brokerage (same ticker, strike, expiration)
2. Place a "buy to close" order
3. Use a limit order at or slightly above the ask price
4. Once filled, your shares are free to sell a new call

The cost of closing is whatever you pay for the buyback. If you sold for $4.00 and buy back at $1.80, your net profit is $2.20 per share ($220 per contract).

Frequently Asked Questions

Does closing early trigger different taxes than letting it expire?

The tax treatment is the same — premium income from a covered call that's bought back is short-term capital gain, just like premium from an option that expires worthless. The timing of when you realize the gain shifts, but the rate doesn't change. Consult a tax advisor for your specific situation.

What if the option is only worth $0.05 — should I still buy it back?

At that point, it's a judgment call. The $5 cost to close is minimal, and it frees your shares immediately. Many sellers close at $0.05-$0.10 as a matter of routine to avoid the small risk of a last-day reversal. Brokerages sometimes offer commission-free closes on options worth $0.05 or less.

What percentage should I target — exactly 50%?

There's no magic number. The 40-60% range is where the risk-reward shift happens for most positions. Some sellers use 50% as a hard rule for simplicity. Others adjust based on how much time remains and how the stock is trading. The point is the principle: don't hold a winning position for diminishing returns.

Can I automate this?

Some brokerages support contingent orders that automatically buy back an option if it reaches a target price. This is worth setting up for each position — it removes the temptation to hold past your target.
