Covered calls on Canadian bank stocks: what to check first

Canadian bank stocks are a common covered-call choice: big companies, steady dividends, and options on the Montreal Exchange. Three things trip sellers up: the ex-dividend date, the earnings calendar, and which listing you sell the call on.

Why people sell calls on Canadian banks

A Covered call means you own 100 shares and sell someone the right to buy them at a set price. You collect a premium now. If the stock ends above the Strike price, your shares are sold at that price.

Canadian banks fit the pattern many sellers look for. They're large, widely held, pay a dividend every quarter, and have listed options in Canadian dollars. That makes them a natural place to start the wheel strategy for someone who already owns them.

The "Big Six" are the usual names: Royal Bank (RY), TD (TD), Scotiabank (BNS), BMO (BMO), CIBC (CM) and National Bank (NA). They're the kind of large, busy names that usually have listed options on the Montreal Exchange. Confirm any name on the exchange's list of option classes before you plan a trade. No ticker here is a recommendation.

The criteria, before any ticker

Check these on any bank before you sell a call:

1. A business you'd hold through a bad year. Banks fall hard when people worry about loans going bad. The premium won't cover that.
2. The ex-dividend date. Know it before you pick an expiry.
3. The earnings date. Canadian banks report on their own calendar, not the US one.
4. Option liquidity. Look at the bid-ask gap and the open interest at your strike.
5. A strike above your cost. Being called away should be a gain, not a loss.

The ex-dividend date and early assignment

Each bank's dividend has an Ex-dividend date. Own the shares at the start of that day and you get the dividend. Sell them before, and you don't.

That's where Early assignment comes in. Canadian stock options can be exercised any day before expiry. If your call is in the money the day before the ex-date, and what's left of its time value is less than the dividend, the buyer may exercise early. They take your shares, and the dividend with them.

The fix is a one-minute check. Look up the ex-date before you pick an expiry. If the call goes in the money as the date gets close, decide ahead of time: buy the call back, or let the shares go. My page on early assignment before a dividend shows the math.

Earnings come on a different calendar

The Big Six run their fiscal year to October 31. So they report a month or so out of step with US banks. Don't assume "earnings season" on the news means your bank reports that week.

Earnings matter because a surprise in loan losses can move a bank stock several percent in a day. Check the date on the bank's investor page. Then decide if you want it inside your trade.

TSX options or the US-listed shares?

Most of the Big Six also trade in New York, with US options. So you can sell a call in two places, on what is the same company.

The rule of thumb: the call has to match the shares. If you own the TSX shares, sell the Montreal option. If you own the US shares, sell the US option. Mixing them means your call isn't covered by those shares, and your broker may block it.

Because the company is Canadian, the dividend isn't hit by US withholding tax, whichever listing you hold. That's different from a US bank. See US withholding tax on option premiums for that side.

A worked example: the call didn't save the shares (hypothetical)

All numbers are made up, for a made-up bank called XYZ.

You own 100 shares of XYZ at $80 ($8,000). You sell a 30-day $84 call for $1.00, collecting $100. Earnings fall inside the window. A $1.00 dividend goes ex during it too.

Then XYZ reports higher loan losses than expected. The stock drops to $70.

Look at the $70 row. The premium and the dividend together covered $200 of a $1,000 drop. The shares are still worth $7,000, so this is a paper loss until you sell. But no call could have stopped it.

Then look at the top row. The stock rose past the strike before the ex-date, the buyer exercised early, and you lost both the upside above $84 and the dividend.

So the call cuts both ways. It caps the good months and barely dents the bad ones.

What to do next with this

If you own Canadian bank shares and want to sell calls:

1. Put the ex-dividend date and earnings date on your calendar for each bank.
2. Pick an expiry that avoids earnings, or decide you're fine holding through it.
3. Pick a strike above your cost, so being called away is a gain.
4. Check the bid-ask gap on the Montreal option. If it's wide, use a limit order near the middle.
5. In a TFSA or RRSP, covered calls are widely allowed, but options permissions differ by broker. Check your broker's options page for that account.
