Rolling the calls in a covered call trade
means to buy back the short calls and sell calls with a
different strike price. Rolling calls is a trade management
technique used to increase return when the stock advances
or ameliorate a loss when it declines (or actually snatch
a profit out of a declining stock). We invented the
Trade Management Calculator™ to manage
the covered call trade all through its life, from open to
close, including rolls. You have to absorb this article
in order to understand how this calculator works, because
no one else anywhere has this calculator. Do you have to
have this calculator in order to roll calls, or to manage
covered call trades? No, but it sure makes life easier for
covered call writers. Even if you are not a CallWriter member,
though, this article will help you with the process of rolling
calls and keeping track of the numbers.
Our
fascinating little covered call calculator has 4 rows, explained
below:
| Row
1 |
|
Original
trade prices and basis (or adjusted numbers
after a roll) |
| Row
2 |
|
Immediate
results of closing the position (current prices) |
| Row
3 |
|
Potential
results of a rollover |
| Row
4 |
|
Potential
results of an alternative rollover |
|
The first thing upon executing
the trade, enter the stock and option symbols and the actual
trade numbers into the calculator's 1st row based on the
fill we got for the trade. Then, when the stock price moves
up or down and we are contemplating closing the trade or
possibly doing a roll, we go to the 2nd row and enter
the new stock price (Current Price) of $46.25 and
the $4.00 asked price to repurchase the short call. There
is no need to look up prices; just hit the update button
to get 15-minute delayed prices. If we want real-time prices,
we have to look that up.
The 2nd rows shows you the immediate profit
or loss in closing out the position and selling the stock.
It is essential to enter these numbers into the 2nd row,
because the 3rd and 4th rows of the calculator work from
these prices to compute the rollover results. I frequently
go through my calculator positions and check each one by
hitting the 2nd row update button to see if the trade is
showing me a profitable close.
Note: When I open a trade,
I normally enter the option symbol in the 3rd
row for the strike immediately below the one
written, and in the 4th row enter the
option symbol for the strike immediately above.
The 3rd row is a possible
rollover (up or down), and the 4th row
is another possible rollover (up or down), which allows
you to look at two different roll possibilities at once.
The 3rd and 4th row calculations assume that the stock price
(Current Price in the 2nd row) doesn't change by expiration
and that either:
| (a) |
|
an
OTM or ATM call expires worthless and you sell the stock
to get the flat return, |
| |
|
or |
| (b) |
|
you are assigned
(called out) of an ITM call and receive the if-called
return |
These assumptions are necessary, since
we can never know where the stock price will be at expiration.
The 3rd and 4th rows work off the numbers in the 1st and
2nd rows in making the roll calculations. Unless and until
you execute a subsequent roll into a different call, the
1st row [$39.95 Cost Basis] remains the baseline for the
trade, and the 2nd row establishes the cost of the roll.
It might be of assistance to look at our sample
calculator with tutorial.
Let's work through an example using hypothetical
stock XYZ. Assume that we've bought XYZ for $42.50
and written the 45 Call on it for a $2.55 premium.
We would enter these figures, along with the stock and option
symbols, into the calculator's 1st row. Your Cost Basis
in the stock (net debit) after running the trade is $39.95,
as shown in the calculator's first row. Now assume that
a week later the stock's price goes up to $46.25 and you
are considering a roll up to the 47.50 call (that is, buying
back the 45 Call and selling the 47.50 Call). It will cost
$4 to buy back the 45 Call, and you'll get $2.50
for writing the $47.50 call.
Rolling up to the 47.50 Call will increase
the Cost Basis to $41.45, as shown in the calculator's
third row. Once we roll into a new call, our basis in the
stock is adjusted, due to buying back the original call
and selling the new call - rolling will always change our
basis. It appears potentially profitable in this example
to roll up, because even though it will increase our cost
basis in the trade, we're setting ourselves up for a substantial
increase in the return... if the stock price holds; if the
stock price comes back down, we'll get whipsawed. After
completing the roll up to the 47.50 Call, we are now in
a different trade with a higher basis, and the calculator
presents the new flat and if-called returns for the roll
in the 3rd row, the same as it did for the original trade
in the 1st row.
Note: You could close this
trade right away for a return of $2.30 (5.4%).
Is it really worth the effort to roll up in this example?
Sometimes it is better to take your money off the table
and find a new trade (and turn your cash).
You can see below how the calculator works
off of the stock basis and assumptions (a) and (b) explained
above. Here is a sample calculator illustration that includes
our hypothetical trade and roll:
Calculator
Position 1

Assume that the price has increased again
to $49, and we believe the advance will continue. How do
we use the calculator to evaluate another roll? We cannot
use the 3rd row of Calculator Position 1 for a subsequent
roll after doing the first roll, because the 3rd row works
off the 1st and 2nd rows, and the 2nd row works off the
1st row, both of which are now obsolete in light of the
initial roll.
The solution is simple and elegant: we
just open a new calculator position to hold the subsequent
roll (it has memory for 24 separate positions).
To do this, check any of the 24 tickboxes on the calculator
that are not being used. We merely enter the numbers from
the original roll into the 1st row of a new calculator field
(Calculator Position 2), like so:
| Data
to be Entered in 1st Row of Calculator Position
2 |
| Stock
Symbol |
|
XYZ |
| Stock
Price |
|
New stock
price at the time of the original roll (46.25) |
| Option
Code |
|
Option
symbol for the strike we're rolling to (XYZKW
for the 47.50 strike) |
| Strike
Price |
|
Strike
price of call we're rolling to (47.50) |
| Premium |
|
Net premium
(original premium, plus roll premium, less buyback
cost) + increase in stock value (4.80) |
|
We cannot just take the 3rd row numbers
from Calculator Position 1, however, and paste them into
the 1st row of a new calculator (Calculator Position 2).
The reason is that the proper starting Premium number for
the adjusted position in Calculator Position 2 (1st row)
must be manually arrived at by the trader.
Thus the 5 pieces of data above must be
manually entered into the 1st row of Calculator Position
2. We must manually calculate the "net premium"
and enter it in the Premium field of Calculator Position
2, but this is the only calculation we have to make by hand
(it only takes seconds to do). Don't complicate this simple
computation in your mind; its only purpose is to reflect
your newly-adjusted cost basis resulting from the original
roll and to take into account the increase in the stock's
value and the net premium received on the roll.
Here is a more detailed example of how
how to calculate the net premium (for the Premium field)
in Calculator Position 2 based upon our original roll:
| Calculating
the Net Premium |
| Original
Premium |
|
+
2.55 |
| Premium
on Roll |
|
+ 2.50 |
| Increase

|
+ 3.75
($46.25 stock price when roll done - $42.50 original
cost) |
| Cost
to Buy Back Calls |
|
-
4.00 |
| Net
Premium |
|
+
4.80 |
|
Here is how Calculator Position 2 for the
XYZ trade would look after the original roll and making
the simple net premium computation:
Calculator
Position 2
The return percentages are slightly
off - lower - than actual returns would be, because we are
presenting the end result of several chains of calculations
in the 1st row of Calculator Position 2 as if they were
original trade entry numbers. But the dollar amounts of
the returns are accurate. Obviously, the trade has increased
the Cost Basis $1.05, from $39.95 to $41.45, which is an
increase in trade risk. The potential returns shown include
the $3.75 increase in the stock price from $42.50 to $46.25,
and realizing the $4.80 flat return or $6.05 if-called return
depends on the stock's price at expiration.
Once these numbers have been entered into
the 1st row of Calculator Position 2, we can look at a subsequent
roll at any time as prices change. If you are not a CallWriter
member and don't have access to our calculator, you can
still calculate closing and roll returns yourself by hand.
Manual ciphering is clumsy, tedious and prone to mistakes
(that's why we invented the calculator), but the math is
not difficult to do.
Rolling calls in covered call trades is
not difficult to accomplish, and the returns are easy to
calculate and keep up with. Rolling calls down is the same
process, using dropping stock prices instead. Our CallWriter
members site contains extensive tutorials on using our Trade
Management Calculator™, including rolls up and down.
Note:
Always keep in mind that the returns shown in the
Trade Management Calculator are potential returns
only, because results always depend on prices realized
upon trade conclusion. Also, the calculator does not take
trade costs into account, which can materially affect
returns where only one contract or a few contracts are
run.
This
issue's Question and Answer:
Exercise of In-the-Money Calls
Question:
I have heard that stock options
must be in the money at least $0.25 for them to be exercised.
Are there any rules on this - when can I expect to be assigned
on an option that is only slightly in the money?
Answer:
There really is only one rule: if the option is $0.75
or more in the money (ITM) at expiration, it will automatically
be exercised for the holder's benefit by the brokerage.
The only way to avoid this, should the holder not want to
exercise, is to advise the broker in advance not to exercise
it. (In that event, if you do not exercise it, your broker
can do so, and keep the profit.) But when the option is
ITM less than that amount, no rules apply, except rules
of thumb. You can certainly expect that an option at least
$0.25 ITM will be exercised.
Keep in mind that professional traders
(market makers, institutions, etc.) have no trading costs.
Thus if the option is even a few pennies ITM they will exercise,
because it is profitable for them to do so, where it would
not be feasible for most individual traders to exercise.
A large open interest of several thousand contracts or more
indicates the presence of professional traders, so in this
situation expect to be called out of stock if any calls
written on it are ITM more than a few cents.
