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 actually works — and how your capital works harder when you redeploy it.

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. By closing at 55% profit and selling a fresh call, you could potentially collect another $3-4 in premium on a new position during the same window you'd have spent waiting for $1.80 on the old one.

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. Instead of 12 cycles per year, you might fit 15-16 cycles because you're recycling capital faster:

• 16 trades x $2.00 (50% of $4.00) = $3,200 in collected premium — but with significantly less risk per trade

The gap narrows further when you factor in reality: not every held-to-expiration trade stays profitable. Some reverse. Some get assigned. The early-close approach sacrifices theoretical maximum income for more consistent, lower-risk actual income.

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 OTM 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.
