Great! I'm glad we're able to restart this discussion. OK, now, how do you trade this position? It's best if we start with a hypothetical. stock at 58. june 60 call at 2. june 55 put at 1 (I'm just making up some numbers). if the stock goes down, my position is a synthetic bearish call vertical, so it profits, no problem there. What if a) stock sits at 58? b) stock rises to 61?....I'm all ears....
Look at it this way: you're long the synthetic 55-60 put spread, for which you paid 3 bucks.
Had you sold the stock at 60, you would have paid a buck for the spread. But you sold it at 58, increasing your cost by $2.00
From that point on, the rules are the same as for any 5-pt put spread. If at expiration the stock is below the lower leg (55), you make 5 bucks minus the $3.00 you paid for the spread = $2.00. If at expiration the stock is above 60, you lose the $3.00 you paid for the spread.
Your breakeven price is 57. For every dollar below that at expiration, you make an additional dollar, down to 55. At 55 you've made 2 dollars, same at 50, 45, etc. At 60 you've lost the $3.00 you paid for the spread - same at 65, 70, and so forth.
At 58 you've lost $1.00, and at 59, you've lost $2.00.
Or if you prefer, you can think of it as having sold the synthetic 55-60 call spread for $2.00. If at settlement the stock is 55 or lower, you pocket the $2.00. If the stock is 60 or above, you lose $5.00 minus the $2.00 you received for the sale of the spread.
Either way it works out the same.
