How to sell a covered call on MSFT

The position is two pieces: long 100 MSFT shares and short one call. The short call obliges you to deliver those shares at $485 if the buyer exercises, and you keep the $670 premium no matter what happens. That's the whole trade — you sold the right tail of your own position.

At August 28, 2026 expiry there are three outcomes. Below $485 the call expires worthless and you keep both the shares and the premium. Above it the shares get called away at $485, for a total return of 5.8% from $464.72 including the premium. Exactly at the strike, you keep everything and a coin flip decides assignment.

Your breakeven on the combined position sits at $458.02 — spot minus the premium collected. That is the only downside protection a covered call gives you: 1.4% of cushion. It is not a hedge.

The risk in a covered call is not the call. It is the 100 shares. Max loss on the structure is $45,802 if MSFT goes to zero, versus $46,472 if you held the shares naked — the premium is the entire difference. Anyone describing this as a "low risk" trade is describing the option leg and ignoring the equity.

MSFT goes ex-dividend on August 20, 2026. An ITM short call is a genuine early-assignment risk the day before: if the remaining extrinsic value is less than the dividend, a rational holder exercises to capture it and your shares disappear early. Check the ex-date before you sell a call that expires after it.

Liquidity is a risk, not a convenience. The moment you most want out of a short-premium position is the moment the spread is widest, and the exit price you modelled at mid will not be available.

Microsoft is what a premium seller's underlying is supposed to look like: implied vol that sits a couple of points above realized between prints, a share price high enough that one contract is a meaningful position, and a dividend small enough that early assignment is a calendar check rather than a constant threat. The yields are unglamorous. They are also the ones that survive a decade.

MSFT's Aug 28 strikes are $5 apart near the money (1.08% of spot). Enough rungs to express a view, few enough that each one moves the economics visibly. 32k contracts of open interest on Aug 28 is workable around the money and thin in the wings — width costs more here than the ladder suggests. 25 strikes on that expiry — 35% of the board — carry prints that agree with their own implied volatility and hold up across the ladder, and those are the strikes priced here. Tight at every listed strike; round-number strikes carry the open interest and the best fills.

Skew is inverted: the 25-delta CALL implies 1.8% more vol than the put. That is the market pricing upside risk above downside risk — a squeeze, a takeover rumour, or a crowded short. Selling calls into an inverted skew pays better than usual and is riskier than usual for exactly the same reason. The term structure is flat inside 1.5% between the two captured expiries, so there is no calendar edge to harvest and no event visibly priced into one month over the other.

At 31% ATM implied vol, the Aug 28 options are pricing a one-standard-deviation move of $38.59 over 27 days — roughly −8.3% to +8.3%, or $426.13 to $503.31. A short-premium structure here is a bet that 8.3% over 27 days is more than MSFT will actually use. That is the thesis, stated honestly.

The specific way people lose money on MSFT: Assuming a quiet chart means quiet options. Microsoft's earnings gaps have repeatedly cleared the implied move while the between-print tape stayed asleep.
