STRADDLES AND STRANGLES
I've been looking at some straddles and strangles on stocks that
I think will see an increase in volatility over the next month or two.
But I'm not sure if I should use a straddle or a strangle. Also, how big
of a move does the stock need to make before I make money on the puts or
the calls?
Straddles and strangles work great in volatile markets and can also
offer a good way to partially hedge a stock portfolio. Both trades consist
of purchases of puts and calls on the same underlying stock with the same
expiration months. The straddle uses options with the same strike price.
The options are both at the money, which means the strike price is equal
to (or very close to) the stock price. The strangle, on the other hand,
uses out of the money options, which means that the strike price of the
call is higher than the stock price and the strike price of the put is
lower than the stock price.
For example, Starbucks (SBUX) is trading for $30.05 a share. We expect
the stock to see a big spike in volatility over the next month, but we
don't know which way it's headed. So we look at a straddle using June options.
The June 30 calls are trading for $2.55 a contract and the June 30 puts
for $2.45. We create the straddle by purchasing 10 June 30 calls and 10
June 30 puts. The cost of the trade is $5.00 a straddle, or $5,000 total
(10 x $5.00 x 100).
Say we also consider a strangle using the June 32.50 calls and the June
27.50 puts. Since both contracts are out of the money, the options will
be cheaper than the straddle. For example, the calls are trading for $1.05
a contract and the puts for $0.95. If 10 strangles are bought, the cost
is $2,000 ($2.00 per strangle x 10 strangles x 100). The cash outlay for
the strangle is a lot less when compared to the straddle.
So which is better, the straddle or the strangle? The first factor to
consider is the risk of each trade. While the strangle will cost less,
there is also a greater risk that both options will expire worthless and
the trade loses 100%. If SBUX is between $27.50 and $32.50 at expiration,
both the puts and the calls expire worthless. On the other hand, the stock
would need to close at exactly $30 for both the puts and the calls to expire
worthless with the straddle.
In addition, the breakevens (or the point where the trade begins to
profit) for the straddle and the strangle will be different. There are,
in fact, two breakevens for both the straddle and the strangle. The breakeven
for the straddle is computed as the strike price of the options plus and
minus cost of the trade. Since each straddle costs $5.00, the upside breakeven
is $35 a share and the downside is $25 a share.
For the strangle, the upside breakeven is computed as the strike price
of the call plus the cost of trade. The downside breakeven equals the strike
price of the put minus the cost of the trade. In this example, it is $34.50
to the upside and $25.50 to the downside. There is a greater chance that
the strangle will make profits when compared to the straddle.
In sum, there are tradeoffs when looking at straddles and strangles.
In the Starbucks example, it takes a bigger move in the stock for the straddle
to generate profits. In other words, the breakevens are wider. The strangle
is also less expensive. However, there is a greater chance that both options
will expire worthless with the strangle if the stock price sits between
those two strikes at expiration. One way to reduce that risk, however,
is to buy options with several months until expiration and close the trade
well before they expire. In fact, we suggest that traders close out all
straddles and strangles at least 30 to 45 days before the options expire.
AT THE MONEY AT EXPIRATION
What happens to short puts and short calls when the stock ends
exactly on the strike price? Does either get assigned?
The short answer is "Probably not." When the strike price of the option
is equal to the price of the underlying asset, the option has no intrinsic
value and will expire worthless. On rare occasions, however, you can face
assignment. It is the option holders' right to exercise the contract if
he or she has the desire to do so. Therefore, if you don't want the risk
of assignment, close the position before expiration.
COST OF A BULL CALL SPREAD
I have bought a bull call spread for 10 contracts for a debit
of $1.10. The bid price for a call with a 50 strike price is $2.40 and
ask price call with a strike price of 55 is $1.30. After the trade was
executed, I received an email confirmation that the net amount for the
50 call is $2,400 and the 55 call is $1,275. Is this correct? I thought
the cost is the difference of the premium ($2.40 - $1.30 = $1.10 x 10 contract
= $1,100). Why did I pay $1,125?
You are correct that the cost of the spread is the difference between
the contract that was purchased and the contract that was sold multiplied
by the number of contracts and multiplied by the multiplier, which for
stocks is 100. You might want to contact your broker. However, it is possible
that the other $25 was a commission for the trade (or $12.50 for each leg).
If so, the cost of the trade is $2,400 minus $1,300 plus $25, which equals
$1,125. The $25 was deducted from the short side of the spread.
