They are intended to assist in shaping your thought process and should not be replicated or implemented without careful consideration.

Example trade step by step

• Microsoft share price: USD 524.23
• Action: Sell one call option (the right for someone else to buy your 100 shares) at a strike of USD 550 expiring this Friday, 31 October 2025.
• Premium received: about USD 4.20 per share (USD 420 total for 100 shares).

If you already own 100 shares, you receive USD 420 today for agreeing to sell them at USD 550 later this week. You keep this money no matter what happens next.

The total value of your 100 shares is about USD 52,423. Earning USD 420 in one week represents about 0.8% of that amount. That may sound small, but it adds up if you repeat this kind of trade several times per year.

If Microsoft rises above USD 550 and your shares are sold, you would receive USD 550 per share plus the USD 4.20 premium, for an effective selling price of USD 554.20. From the current level, that’s a potential gain of about 5.7% for the week.

What could happen by expiry

So, if the price moves only a little or not at all, you earn money. If it jumps higher, you still make a nice return up to the 550 level but give up any gains beyond that.

Managing your position

Once the trade is open, here are three simple ways to handle it:

1. Let it expire: If Microsoft stays below 550, the option expires, and you keep both your shares and the premium.
2. If assigned (sold at 550): You sell your shares at 550 and can later sell a cash-secured put (another conservative option strategy) to try to buy them back at a lower price.
3. Roll the option: If the stock hovers near 550, you can buy back the option before expiry and sell another one for the next week or a higher strike. This lets you continue collecting premiums while keeping your shares.

Risks and what to keep in mind

• The main trade-off is that your upside is limited. If Microsoft jumps far above 550, you won’t benefit beyond that level.
• There’s a small chance your shares get called away early, especially if the option moves deep into profit.
• Expected moves are estimates based on option prices—real moves can be much larger.
• Taxes, transaction costs, and timing can affect results.

FAQ

1. What if I don’t own 100 shares?
You can’t sell a standard covered call without owning at least 100 shares. Each option contract represents 100 shares. However, you can still follow the idea by watching how premiums change or by trading a smaller-sized product like a mini contract (if available).

2. Can I lose money with a covered call?
Yes, if the stock price falls, your shares can lose value. The option premium you collect provides a small cushion, but it doesn’t protect you from a large drop.

3. Why not choose a lower strike?
A lower strike gives you more premium but increases the chance that your shares will be sold. Choosing a higher strike gives you less income but more room for price gains.

4. What happens if the stock soars far above my strike?
You’ll sell your shares at the strike price and miss out on further gains. But remember, you entered the trade knowing that was part of the deal—you traded unlimited upside for a guaranteed premium.

The takeaway

Selling a short-term covered call on Microsoft at the 550 strike lets long-term investors earn around 0.8% in a week while still participating in moderate upside. It’s a steady, conservative approach that uses the market’s short-term excitement around earnings to your advantage. Even if the stock goes nowhere, you still collect the premium—turning market calm into a small but reliable source of extra income.
