Excercising a Call Option for the Dividend

I recently had an email conversation with an experienced option trader.  He's not a full-time trader, but has been using options for several years.  The point of mentioning this is to illustrate that anyone can have a blind spot that's difficult to resolve.

Hi Mark,

I've been buying ITM calls on several stocks – trying to capture upside, while limiting potential losses. Usually, I've done these 10% ITM, and typically trade 6-month options.

Eventually I may do it for nearer months, and roll more often, but I wanted to get going with positions I didn't have to watch so closely.

For investors, rather than traders, I prefer the 6-month options you are using.  In fact, I recently blogged on that idea.

 

I choose stocks that have little or no dividend, because the higher yielding stocks have less volatility, and presumably need less 'protection'. One stock that I've done this for is PG.  With a current yield of almost 3%, I'm questioning the wisdom of this choice.

 

PG has an upcoming dividend of $0.44, with an ex-dividend date this Apr21. [Obviously it's now after that ex-dividend date] My Oct $57.50 call is $6.10, with PG now at 63.00.

Can I expect the value of my call to drop by this $0.44 amount on Apr21, and the same amount on the Jul21 ex-date?  Am I leaving money on the table if I buy such an ITM call and don't exercise or sell before the first ex-date?

Assume you exercise the call. Look at the interest rate you must pay to carry stock (which may be almost zero if you have a large cash balance) from the day you would exercise – before ex-div date please – through expiration.  If the cost to own stock is greater than the dividend, then you obviously do not want to exercise. 

If you can exercise profitably by that standard, in return for collecting the dividend you gain substantial downside risk.  If you buy the Oct 57.5 put, you would own a position equivalent to your long call (long stock plus long put = long call).  If the cost to carry
plus the cost of the put is LESS than the dividend, then you should exercise
to earn that extra difference. [Don't ignore trading expenses]

The problem arises when you cannot buy that put at an appropriate price, and that's almost all the time. 

In general, a call is an exercise for the  dividend when two things obtain:  1) delta = 100.  That does not mean 99;  2) Time premium is zero.  That means you cannot sell the call and collect a price above the option's intrinsic value.  When the option bid is below parity (intrinsic value), there is no time premium remaining in the option.

If youmcan collect time premium, then it's more profitable to unload your call and NOT exercise. To prove that to yourself, check the price of the option when the stock opens for trading on ex-dividend day.  You will see that the time premium in the option is greater than the dividend. 

In other words, you are better off by NOT exercising. Remember, exercising gives you all the downside risk you rejected when buying the call in the first place.  If the put is not cheap enough to buy (eliminating the risk) then you do not want to exercise the call.

For a low yielding stock, I really don't care about the dividend. I'm not sure I want to do an ITM play if I'm squandering the equivalent of a 3% yield, as in this example.

You are not squandering anything.  This is a basic part of how options work.

If the option is not truly an exercise for the dividend, then you bought the option – at a premium that recognized the stock price would be lower – due to the dividend.  In other words, you got a 'bargain' on the call when you bought it.  If there were no dividend, the call would have been priced higher.

However, when the stock rallies, your call may move far enough in the money that it becomes an exercise for the dividend.  Please be aware that not every ITM option should be exercised. And that's especially true for 6-month options.  The Apr 57.5 call was probably a good option to exercise, but not an October call.

If your call should be exercised (by the criteria above) and you don't want to do that, just sell it.  Then buy a different call, if you want to maintain an investment in this company. Perhaps the Oct 60 call?

The conversation continued:

If I don't really leave money on the table by not exercising (actually, I'd just sell the option before ex-div date - I have no interest in the stock itself), I'd really prefer to let the option ride, and hope the stock goes up over time. I'm not interested in rapid trading and over-trading. 

Some options must be exercised or it is tossing money in the trash.  Use a calculator.  Calculate theoretical value day before ex-div and day after (lower price of stock by dividend amount).  If the option is WORTH LESS  the 2nd day, then it should be exercised or sold (prior to ex-date).   Replacing the call is a separate decision.


Right now, the Oct 57.5 PG call has a delta of .75, and at $6.10, has a time premium of $0.60, given the stock is now at $63.00. So, you seem to be saying that there is no point in exercising (or selling back the call) before the Apr21 ex-div date. Will the option drop in price to $5.56 on that date ($6.10 less $0.44)? I still need to wrap my head around that.

It will not decline in price.  If delta is 75, nothing should change.  The computer 'know' the stock will be lower (due to dividend) and that information is already factored into the option price.  Do as I suggested above.  Use a calculator. If you don't do that, you will not discover all you need to know.

And if it does drop in price, why do you think it would be $0.44?  The delta is not 100.  You are over-thinking this simple problem.

The conversation continued in another email

I'll follow PG ITM option prices, as PG goes ex-div next week. 
Below is
what Hoadley would say for my PG 57.5 call. I set the expiration for May. The graph's red line clearly predicts an increase in the call's value on the ex-date of apr21.

No, it does not.

Likewise for the yellow line, were the ex-date to be May 15. Why do you say this is wrong?

I cannot tell you how disappointing it is – that you ask this question.  You have been trading options for too long not to understand this.

You are not thinking – you are just using an available graph to get a quick answer.  You are assuming the graph is answering your question – but it is ignoring your question and choosing which question to answer.  Thus, it gives the right answer to the wrong question.    Use the calculator to get the right
answer.  More on this below.


Let's look at it this way:

1) Have you ever seen a call increase in value – overnight – when the stock price is not higher and/or the implied volatility is not higher?

2) The question you are asking Mr. Hoadley's graph is:  If the stock price is unchanged on ex-div date, will the value of my call change?  Good question. 
However, the graph answers this question:  If the stock trades ex-dividend, and if the stock price rises by the amount of that dividend, does the value of my call change?



3) Take a close look at the graph. Specifically the data below the graph.  The stock price is 63.  The stock price is not 62.56.  That is the price at which the stock would open for trading on ex-dividend day.  It's at that price – down 44 cents, but really  'unchanged' – that the call value remains the same (except for a decline – if any – due to theta. 

The reason you see the call price go up is because this graph shows the stock rising 44 cents to 63


That's what I mean by just looking at the graph and assuming it's
useful.  That's why a calculator is better.  Using the calculator, you would set the stock
price to 62.56 and not make this mistake.

I truly hope this clarifies the situation.

Exercising Call Options for the Dividend

Is there any circumstance where I would lose the dividend by writing covered calls?


GK

***

Yes there is that possibility. 

When you sold the call option, you granted to the buyer the right to purchase your shares by paying the strike price per share.  The option owner may elect to do that (by exercising the call option) at any time prior to expiration.  You have no say in the matter. You cannot force the call owner to
exercise, nor can you prevent it.

As soon as the option is exercised, the option owner is considered to have bought the shares.  As with a traditional stock purchase, the stock trade settles three days later.  As long as the option is exercised (and you are assigned an exercise notice), the stock has been sold. 

If this exercise occurs before the stock trades ex-dividend (without the dividend), then the trade settles in time for the person who exercised the option to be declared the stockholder of record when the stock trades ex-dividend, and hence, collects that dividend.  You, as the former shareholder do not get that dividend.

The larger the dividend, the greater the possibility of losing the dividend.

Also, the closer ex-dividend date is to expiration, the greater that possibility.  

One point must be mentioned.  No one will exercise an option that is not in the money.  And the option must be sufficiently in the money before it's owner will exercise.  Why? 

The call owner has a limited liability.  If the stock tumbles, the maximum loss is the value of the call option.  Once the exercise is complete, the former option owner now owns stock.  If the stock tumbles, the loss can be large – much larger than the loss experienced by the option owner.  Thus, the call must be far enough in the money that the person who exercises is willing to take the risk of owning stock instead of the call option.  The break point comes at the strike price of the option.  The exerciser must be willing to bet – and the payoff is the dividend – that the stock will not tumble below the strike price – where the loss can be substantial.

When exercising, the best time is one day before the stock trades ex-dividend.

You learn about being assigned an exercise notice the morning after the option owner exercises. Thus, if you see that you still own the shares on the morning the stock goes ex-dividend, then you collect the dividend. When  you no longer own the stock, and are no longer short the call option, on that ex-dividend day, then you do not collect the dividend.  How can you determine the likelihood of being assigned for that dividend?  If the call option is trading at parity – and that means it has zero time premium – and if the delta is 100, then it's right for the call owner to exercise.  Some call owners exercise more aggressively, but that is beyond your control.
