Backspreads
Definition : An option strategy consisting of more long options than short
options having the same expiration month. Typically, the trader is long calls
(or puts) in one series of options and short a fewer number of calls (or puts)
in another series with the same expiration month in the same option class.
Some traders, such as market makers, refer generically to any delta-neutral
long-gamma position as a backspread.
Shades of Gray
In its simplest form, trading a backspread is trading a one-by-two call or put
spread and holding it until expiration in hopes that the underlying stocks
price will make a big move, particularly in the more favorable direction.
But holding a backspread to expiration as described has its challenges. Lets
look at a hypothetical example of a backspread held to term and its at-
expiration diagram.
With the stock at $71 and one month until March expiration:
In this example, there is a credit of 3.20 from the sale of the 70 call and a
debit of 1.10 for each of the two 75 calls. This yields a total net credit of
1.00 (3.20 1.10 1.10). Lets consider how this trade performs if it is held
until expiration.
If the stock falls below $70 at expiration, all the calls expire and the 1.00
credit is all profit. If the stock is between $70 and $75 at expiration, the 70
call is in-the-money (ITM) and the 1.00 delta starts racking up losses
above the breakeven of $71 (the strike plus the credit). At $75 a share this
trade suffers its maximum potential loss of $4. If the stock is above $75 at
expiration, the 75 calls are ITM. The net delta of +1.00, resulting from the
+2.00 deltas of the 75 calls along with the 1.00 delta of the 70 call, makes
money as the stock rises. To the upside, the trade is profitable once the
stock is at a high enough price for the gain on the two 75 calls to make up
