SPX Credit Spread Trader

Quote from zhangw:

SPX closed @1395 last Friday. My outlook for the market: SPX is not going up or down too much in two weeks. I’m thinking to do the following 5 point Iron Condor Spread with SPX (paper trade):

Buy 10 Feb 1435 Call
Sell 10 Feb 1430 Call
Credit 1.25 x 1000 = 1,250 (estimation)

Buy 10 Feb 1360 Put
Sell 10 Feb 1355 Put
Credit 1.25 x 1000 = 1,250 (estimation)

Maximum gain = 2,500 if SPX closes between 1360 and 1430 on expiration day.
Maximum loss = 2,500 if SPX closes below 1357.50 or above 1432.50 on expiration day.

The reasons I would like to try this strategy:
1. Profit : Loss = 1:1 (not bad)
2. Limit Risk = 2,500 that is 5% of my account value (assume I have $50,00 in my account)
3. I don’t worry too much about the adjustment if SPX is closed to my short strikes. (Right now I am not clear about the exit strategy and adjustment).

Any comments and advices about this strategy would be greatly appreciated.

1. Did you paper-trade? It is hard to get the price at the mid.
2. Adjustment is hard without large slippage when it is close to expiration.
3. With big movement, you should expect a larger slippage.
4. A plan of no adjustment is a better exit strategy in this case imo. But I don't recommend this trade. Your gamma risk is too high.
 
Thanks to all replies for my post.


Mark,

Glad to see you come back to this thread. Thanks for your insight.

I have some experience on selling DOTM spreads on SPX, RUT & GOOG, but I have never done buying Iron Condors. Before using this strategy, I need to research, study, get some experiences from others, and do paper trading. As SPX bid & ask spreads are so widen, I’ll use IBM as example to explain what I want to know:

Today IBM closed @103.59. As it had good earning and has good out look, I think it will not go down too much in 5 weeks.

Sell 10 Mar IBM 95 put @1.55 Delta -0.21
Buy 10 Mar IBM 85 put @0.40
Credit 1.15
Maximum Gain$1,150; Maximum Loss $8,850 (it could happen if the market melts down)
Exit point: if the price for the spread = 3x 1.15 =3.45, I’ll take loss to get out.
I might do some adjustments based on the condition of the market.

Now I would like to try Iron Condors:
Sell 10 Mar IBM 100 put @2.90 Delta 0.35
Buy 10 Mar IBM 95 put @1.65
Credit 1.25

Sell 10 Mar IBM 110 call @1.95 Delta 0.30
Buy 10 Mar IBM 115 call @0.95
Credit 1.00
Maximum gain $2,250; Maximum Loss $2,750 (no matter what happen with the market)

Compare these two strategies:

Margin Requirement: same
Maximum Gain: $1,150 vs $2,250
Maximum Loss: $8,850 vs $2,750
Probability of winning the trade: 79% vs 65%
Risk/Reward: Bad vs No bad

Please advise:
1. Whether my analysis is correct.
2. How to control my risk by adjustment.
3. Is it a viable strategy in this volatile market?
4. SPX, SPY, QQQQ, Individual Stock with higher price, like IBM/GS, for this strategy which one I should use that I can get better return?

I have a question about your probability calculation. In the first case, you lose with a 10 point (approx) move down. You say this is 21% likely. In the second case, you lose with a 10 point (approx) move in either direction. You say this is 35% likely. Intuitively, should this not be about double (42%) likely?

Be careful, the probability of winning in the second trade is 0.65x0.70=45.5%.

Not to oversimplify, but an IC is merely TWO DOTM spreads done simultaneously. One in calls, one it puts. (But you already knew that.) Of course then don't have to be DOTM, but if that's your preference, then that's your preference.

When you switched to iron condors, you changed the put spread you were selling? Why did you do that? Is your outlook for the stock different because you are trading an IC rather than a spread? That makes no sense to me.

Of course your risk is less with the iron condor. The primary reason is because you are selling 5-point spreads, rather than the 10-point spread you had in mind originally. Thus, THE COMPARISONS ARE MEANINGLESS. You cannot compare a 10-pointer with a 5-pointer and expect the risks to me similar.

In addition, the risk/reward is always better for the iron condor because you collect more premium. That means (for similar width spreads) that the potential profit is better and the maximum loss is also better. Does that mean that ICs are always better than simply selling put spreads? No. When buying the IC, the probability of having a winning trade is less than when you sell only the put (or call) spread. That's because you can lose on either end with an IC

And keep in mind, the maximum loss you describe is only true if you hold to expiration or exercise good discipline. It's quite easy to have the market move substantially higher and you close the call spread at a loss. You should close out the put spread at the same time (because there is so little potential profit remaining). If you fail to do that, a subsequent market downturn can result in an additional loss from the put spread.

It's a viable strategy, but no one gives away money. there is risk to owning IC positions.

Asking which one to use to get a 'better return' is the WRONG QUESTION. When you buy iron condors (or sell DOTM spreads) you are placing a bet on the market. Choose the underlying that makes you more comfortable. You can get great returns on GOOG, but do you really want to take the risk? That's the question for you to answer.

You should look to trade within your own comfort zone - trade an underlying that allows you to sleep at night - seeking the highest return is NOT the right choice.

Hi Mark, you have written:
"In addition, the risk/reward is always better for the iron condor because you collect more premium."

Excuse me but I don't agree with you.:) The risk/reward ratio is theoretically always the same.

With IC you collect more premium but you have more risk in your trade. With a vertical your risk is only for one direction, but with IC you take risk in both legs of the spread.

You can look the numbers that I put before and you will see what I'm talking about.

Sugar:

The risk reward ratio is better, but the probability distribution function of the success changes.

IOW the expectancy is almost the same (both are zero without slippage and commission cost).

NOT TRUE

<b>With a vertical your risk is only for one direction, but with IC you take risk in both legs of the spread. </b>

TRUE, but irrelevant

<b>You can look the numbers that I put before and you will see what I'm talking about.</b>

RISK is defined as the maximum possible loss for the position. It is not defined by the probability of losing that amount.

I believe that is where we differ - in the definition.

When you open a 5-point put spread, the max loss is $500 less premium.

When you open an IC with 5-point spreads, the max loss is the same $500 less premium. But the premium is higher with the IC and the max loss is LESS.

Thus, RISK is less. By definition.

Mark

 
Apologies, I agree with you about Risk/reward ratio. It was a terminological confusion.

What I wanted to express is that risk is the same in both trades.

Thanks.
