Quote from yuckyellow:
A couple of specific points I have been pondering...
1. I have read not to open a spread which shows less than an 85% chance of expiring in the money. Do you agree with this statement?
2. What is a good return on risk for this type of trade?
3. When do you exit if the trade is moving against you?
Thanks
Vertical spreads are more frequently referred to as bull or bear spreads and as credit or debit spreads.
Specific points your pondering:
1) No, I would not agree. If your position is a credit spread you'd want both options to expire out-of-the-money. The following are for examples only and are not to be considered as investment advice. All prices are based on closing prices and are at the natural without commissions.
Occidental Petroleum (OXY) closed at 100.93
A bull credit spread with puts:
Buy to Open (BPO) 10 July 100 @ 2.03
Sell to Open (SPO) 10 July 97.50 @ 1.24
The credit on the spread is .79 , with the spread of 2.50 points the maintenance requirement is $2,500 on 10 contracts. With the credit of .79 x 10 equals a credit of $790 or a initial requirement (max loss) of $1,710. $790 divided by $1,710 = a 46.20% return IF all options expire worthless and you keep the credit. Breakeven point @ 99.21.
or
BPO 10 July 95 @ .72
SPO 10 July 97.50 @ 1.19
The credit is .47 or $470 divided by the initial req. (max loss) of $2,030 for a 23.15% return and a BE of 97.03.
As you can see the more you are out of the money the lower the return, but the more the underlying must move against you to be a problem. In these two examples, the underlying is above the short strike in both examples. If one was to take on a bull position with the underlying in-the-money the potential return would be higher but in that case the underlying must move higher for the options to expire.
A Bull debit spread with calls:
BCO 10 July 95 @ 6.75
SCO 10 July 100 @ 3.00
Debit = 3.75 or $3,750 (max loss) Here you would want both options to expire In-the-money for the full 5 point spread, or a 33.33% profit less commissions.
or
BCO 10 July 100 @ 3.05
SCO 10 July 105 @ .88
Debit 2.17 or $2,170, if both options are ITM at expiration for 5 points the return would be 130.41% . But the underlying must move higher.
You should see how to be bearish with puts or calls credit or debit.
All the examples above should answer your # 2. The Risk should always be justified by the Return. Just how bullish or bearish (or neutral) are you? It's best to enter the trades as a spread order to make sure you have both sides. Most of the time I do market orders. Some will say they get ripped on market orders, but most of the time the difference is less than a nickel, if a nickel is going to make or break the trade then you probably shouldn't be doing it in the first place.
As for #3. I've seen a lot of traders, and one thing seems common. I hear them say .. " I wish I was out of that.... If it will just get back to breakeven I'll get out" If you find your wishing you didn't have a position, then GET OUT of the position. In options one is reevaluating the position fairly often. I'm not saying you have to watch it tick for tick. How much time is remaining, are you In, or Out the money... is your position one that you MUST exit in order to avoid the additional cost of exercise and/or assignment. All play a factor in when or if you enter the exit order.
