Writing covered calls on company stock you already own turns those shares into a source of option premium, paid by a buyer who wants the right to purchase your shares at a set strike price. You keep the premium either way. In return, you give up gains above the strike and accept that your shares may be called away.
How a covered call works
You own the shares and sell a call option on them. The buyer pays you a premium now. If the stock stays below the strike through expiration, the call expires worthless and you keep both the shares and the premium. If the stock rises above the strike, the buyer can exercise and you must deliver the shares at the strike price.
The trade does nothing to protect you on the downside, other than the small cushion of premium received. A covered call is an income strategy, not a hedge, and that distinction matters for anyone holding a concentrated position.
Who covered calls fit
The strategy suits a narrow but real group: holders who plan to keep a block of company stock for years, are comfortable with full downside exposure, and would accept selling at a higher price. Examples include founders keeping a core position for control or conviction, and executives with ownership guidelines who cannot sell below a required level anyway.
It fits poorly when your real problem is concentration risk. If a large decline would damage your plans, premium income does not solve that, and protection through a put or collar, discussed in the guide to equity collars, is the better tool.
Choosing strike and term
- Out-of-the-money strikes pay less premium but leave room for the stock to rise before the call bites.
- Short terms, such as one to three months, let you reset the strike regularly and keep more control.
- Volatility drives premium. Tech stocks with high implied volatility pay more, precisely because large moves are more likely.
Many writers sell calls on only part of a position, leaving the rest uncapped. That limits both the income and the chance of an unwanted sale.
Watch dividend dates if your company pays one, because call buyers sometimes exercise early to capture the dividend. For growth tech stocks that pay nothing, early exercise is uncommon, but it remains possible for calls that are deep in the money near expiration.
The tax rules
The premium is not taxed when received. If the call expires, the premium is short-term capital gain at expiration, regardless of how long you have held the stock. If the call is exercised, the premium is added to your sale proceeds, and the gain on the shares takes the holding period of the shares themselves.
Assignment is the main tax risk. Low-basis founder or early-exercised shares that are called away produce a large gain you may not have planned for. Some writers buy back calls that move into the money to avoid that, which converts the problem into a loss on the call.
The qualified covered call exception
Selling a call against stock you own creates offsetting positions, which would normally be a straddle with deferred losses and suspended holding periods. A qualified covered call is excluded. Broadly, it must be exchange-traded, have more than 30 days to expiration when written, and not be deep in the money under the statutory strike tests.
Even a qualified call that is in the money can suspend the stock’s holding period while it is open. The rules, and why they usually do not rescue a collar, are covered in the article on collar taxation.
Company policy and insider rules
For employees and executives of public companies, permission is the first hurdle. Many insider trading policies prohibit trading options on company stock, including selling calls, because option activity can look like speculation on short-term moves. Some policies ban it only for officers and directors; others extend the ban to everyone.
Officers and directors face additional rules. Writing a call is a reportable derivative transaction under Section 16, and it can be matched with purchases within six months for short-swing profit recovery. Trades must also fall in open windows and be pre-cleared, and nobody may write calls while aware of material nonpublic information.
Writing calls on a regular schedule under a Rule 10b5-1 plan is possible in principle, but it is unusual and needs counsel’s review. The basics of those plans are covered in the guide to Rule 10b5-1 plans.
Covered calls versus selling outright
A common mistake is to write calls on shares you actually want to sell, hoping to be paid while you wait. If the stock falls, you collect the premium and keep a smaller position than you could have sold earlier. If it rises, the shares are called away at the strike. Neither is the outcome you planned.
The cleaner approach separates the decisions. Decide how many shares you will keep for the long term. Sell or hedge the rest.
Write calls only on the core block you would hold through a drawdown, and size the calls so that assignment would not create a gain you cannot absorb. If you want protection and income together, a collar is the combined structure, as discussed in the article on collar strategy after lockup.
The bottom line on covered calls on company stock
Covered calls on company stock produce income from shares you plan to keep, at the cost of capped upside and possible assignment. They provide no real downside protection. Confirm your company’s policy first, use them only on a core holding, and review the tax effect of assignment with a CPA.
Do covered calls protect against a stock decline?
Only by the amount of premium received. The shares remain fully exposed below that, so covered calls are an income strategy rather than a hedge.
How is covered call premium taxed?
If the call expires, the premium is short-term capital gain. If it is exercised, the premium is added to the sale proceeds of the shares, which keep their own holding period.
Can employees sell calls on company stock?
Often not. Many insider trading policies prohibit options trading in company stock. Where it is allowed, pre-clearance and open trading windows usually apply.
What happens if my shares are called away?
You sell them at the strike price, and any gain over your basis is taxed. Low-basis founder shares can produce a large, unplanned gain on assignment.
