First things first: what is a call option?
Before discussing covered calls, it helps to start with the basics.
A call option is a contract linked to a stock. It always has three key elements:
-
a price (the strike price)
-
a date (the expiry date)
-
a number of shares (one standard option contract always represents 100 shares)
There are two very different ways to use a call option.
Buying a call option
When you buy a call option, you buy the right (but not the obligation) to buy 100 shares at the strike price before expiry.
-
You pay money upfront.
-
You benefit only if the stock rises strongly.
-
If nothing happens, the option can expire worthless.
Buying a call is a directional bet on higher prices.
Selling a call option
When you sell a call option, you take the opposite role.
-
You receive money upfront (the option premium).
-
You give someone else the right to buy your shares at the strike price.
-
You accept an obligation if the stock rises above that level.
In this article, we focus on selling a call option, not buying one.
What is a covered call?
A covered call is one of the most basic and conservative option strategies.
It combines two positions:
-
You own at least 100 shares of a stock.
-
You sell one call option on those same shares.
The word covered simply means that if the option buyer exercises their right, you already own the shares needed to deliver them.
By selling the call option:
-
You receive cash upfront.
-
You agree to sell your shares at a fixed price if the option expires in the money.
In simple terms, a covered call means:
“I am happy to sell my shares at a higher price, and I want to earn some income while I wait.”
The trade-off is clear and unavoidable: you earn income today, but you give up part of the upside if the stock continues to rise strongly.
Why Micron is a candidate for a covered call right now
Micron reported its fiscal first-quarter 2026 results on 17 December 2025. Since then, the share price has moved sharply higher, reflecting strong demand for memory linked to artificial intelligence infrastructure.
After such a rally, two things are often true at the same time:
-
The long-term story may still be intact.
-
Short-term uncertainty remains high.
That uncertainty shows up in the options market. Option prices on Micron remain elevated compared with calmer periods.
For covered call sellers, this matters because:
-
Higher uncertainty usually leads to higher option premiums.
-
Higher premiums mean more income for the same commitment.
This does not mean the rally must end. It simply means investors are willing to pay up for upside exposure, and existing shareholders can choose to sell some of that upside in exchange for income.
