Some Credit Spread Tricks
by John Brasher, CallWriter Publisher
|
Plenty
of CallWriter members like to write a credit spread, which
is the sale of a call (or put) and simultaneous purchase of
a call (or put) that is further out of the money. The call
purchased is cheaper than the premium received for the call
sold, which generates a net credit on the trade. That's right,
you get paid to run the trade. If the trade goes wrong, then
of course a loss can be realized. But as with every trading
strategy, there are tricks to the trade. This article will
cover some of the more useful ones. |

A credit spread is the simultaneous sale
of one call (or put) and the purchase of a call (or put) that is
further out of the money (OTM) than the call or put sold and therefore
less expensive. There are two types of credit spreads: bear call
spreads and bull put spreads. The "spread" is the difference
between the two strike prices.

(Bearish) |

Buy a further OTM call |

| Bull Put Spread |
|
• Write an OTM put (strike
is lower than the stock's price) |

(Bullish) |
|
•
Buy a further OTM put |
Here are examples of the two spreads
on hypothetical stock XYZ, when the stock is trading at $20 per
share:

The net credit
is the difference between the premium received for the call (or
put) sold and the cost of the call (or put) purchased - in other
words, the amount the trader pockets. The net spread is the
difference between the spread and the net credit received. The net
spread is the maximum amount the trader is at risk if the trade
goes wrong. The breakeven point is the strike price of the
call sold plus the amount of the net credit, or in the case of a
put spread, the strike price of the put sold minus the net credit.
The credit spread is a type of covered write, actually; the call
or put sold is not naked because the long call or put bought positions
the trader to buy (sell) the underlying stock at a set price. The
call or put sold is "naked" only to the extent of the net spread
- this is the net amount not covered by the long call or put.
If the stock
price stays below the call strike sold (22.50 Call in the above
examples), or stays above the put strike sold (17.50 Put in the
above examples), the credit spread generates its maximum profit
- the original net credit. In the examples above, the $20 stock
has to advance $2.50 to begin putting the bear call spread in danger,
and has to fall $2.50 to start putting the bull put spread in danger.
The trader's
objectives are to (1) pocket the net credit, and (2) if the opportunity
presents itself due to a collapse in the option premiums, close
the spread at a profit by selling the long call or put and buying
back the short call or put.
The bear call spread is bearish in
nature, and the trader creates it when the stock is expected not
to advance before expiration as high as the call strike sold. The
bull put spread is bullish in nature, and the trader
creates it when the stock is expected to advance or at least stay
above the put strike sold. It is not necessary that the stock advance
or decline for the trade to win; it only needs to not rise or fall
too much by expiration.
1. Create
them out of the money. Credit spreads should be created
out of the money, in order to leave room for the stock to oscillate.
For example, if the stock is 29.50 and you create a Short 30C/Long
35C bear call credit spread, you have left only $0.50 of room for
the stock to advance before it starts eating into your breakeven.
The strike sold (much less the entire spread) should never be in
the money, or even at the money.
2. The ultimate
credit spread stop loss secret. We don't find it useful
to set a stop loss on a credit spread in relation to the stock's
price or the spread's breakeven point. When writing a credit spread,
only write one with a strong resistance level (bear call) or support
level (bull put) between the current stock price and the strike
price of the short call. In other words, construct the trade so
that the stock has to break a significant support or resistance
level in order to put the trade under water. If the support or resistance
level is broken, you should close the spread before the breakeven
is violated. Make the stock work hard in order to hurt you - in
other words, put every obstacle possible in the stock's way. To
enter a stop order, use a contingent order: if the stock hits the
stop price, the broker should close the spread.
Example:
In the hypothetical XYZ trades above, there should be a strong
resistance level between the $20 stock price and the short
22.50 Call if a bear call spread is created, or there should be
a strong support level between the $20 stock price and
the short 17.50 Put if a bull put spread is created.
3. Be picky;
be very picky. Volatile stocks are poor choices for credit
spreads, as are stocks expecting major news before expiration. For
bear call spreads write lousy stocks or those that otherwise present
little chance of advancing, and for bull put spreads write good
solid stocks very unlikely to fall. As with covered calls, we use
a combination of technical analysis and fundamentals. Keep in mind
that stocks can move hard after the bell, at a point when you cannot
close the spread.
4. Look for
early closing opportunities. Sometimes the implied volatility
causing high option premiums will collapse, allowing the spread
to be closed (sell the long call and buy back the short call) at
a nice profit. This will not happen in every spread, but be looking
for the opportunity.
5. Will you
be exercised early? If you are exercised when the short
call is in the money, a loss is possible, but how likely is early
exercise, really? US equity options can be exercised at any time
before expiration. They are only exercised when in the money, of
course, and generally are exercised before expiration only when
there is no time value left (and thus no point waiting for
expiration).
Whenever you
see a play on CallWriter's Real Time Lists™ that you suspect might
permit a good credit spread, it only takes a few seconds to figure
it out. First, click on the option symbol on the list, which will
pull up the CallWriter Research Page with covered call chains displayed.
Simply change the Chain Type from covered calls to put spreads or
call spreads for the month desired, which will bring up a list of
possible spreads.
Credit spreads
put instant money in your account, which is very nice. And unlike
the case with debit spreads or long option trades, the stock does
not have to move in order to make the trader money. Done properly
on non-volatile stocks and those not expecting significant news,
credit spreads are a walk in the park.
