Ok..... let's see what this trade is.
SHORT 166 CALL . . . . . 5.65 . . . . . is a
bearish position, giving some one else the right to buy at $166, and obligating you to sell at 166
LONG 166 PUT . . . . . 6.85 . . . . . is a
bearish position, right to sell at 166
LONG 168 CALL . . . . . 4.53 . . . . . is a
bullish position, right to buy at 168
"trades" like the above are really not a "thing", they are just two positions. You have a SPREAD on the Calls......... and then, for some reason, you also happen to own a Long Put that has nothing to do with the call spread.
If we break down the Call Spread, you are Long the 168's and short the 166's. When you entered this position, you paid $4.53 for the Long 168 and sold the short 166 for $5.65, resulting in a credit in your pocket for $1.12.
Now, 3 things can happen to the price of the underlying security.
It can go UP. It can go DOWN. It can stay the SAME.
If the
price goes down below $166, both Calls become worthless, upon expiration. And you keep the
$1.12 for profit.
If the price is between $166 and $167.99, the short call has value, and the Long call you own becomes worthless. If the price is between $166 and $167.12, you will make a small profit of between $1.12 and $0.01. At prices between $167.13 and $1.68 you will lose between $0.01 and $0.32
If the
price goes above $168, then the value of the short 166 and the long 168 will have value, with the short ones always being $2 more valuable. At
a price above $168 you will lose $0.88.
To recap:
- $159.99 and below $1.12 profit
- $166.-167.12 is profit of $1.12 to $0 (the premium already in your pocket)
- $167.13 to $168.00 is loss of $0.01 to $0.87
- $168.01 and above is a $0.88 loss
The Call side of your trade has a maximum gain of $1.12 if the stocks go down. and a maximum loss of $0.88 if the price goes up. Now, if the risk/reward of risking $0.88 (plus the margin requirements, commissions, etc) to make an uncertain $1.12 is a good trade, that is up to each individual's risk tolerances.
__________
As for the Put that is tossed into the equation, it only a good trade if the price goes below $159.15 (the 166 strike price less the cost of 6.85 to buy it.) No idea if the Put is a good trade or not, but some other guy has $6.85 of your money in his pocket, and he is equally confident that you will lose money as you are that you will make money, hence,
the Zero-sum.
