I was speculating, over the weekend, the relative risk of the RUT versus the IWM.
So, I created a spreadsheet that computes profit, risk, probability of success and return on investment.
I think the results are interesting.
Assumptions:
On the IWM trades I tried to match the profit potential of the RUT.
As the spread increases and the number of options, so does the risk, while the ROI decreases.
It would appear that a single trade on the RUT is actually much less risky than putting on 15 IWM trades over a several day period.
What do you think?
| Sell APR Call vertical | -190 / +195 |
| Credit $1.25 | Spread $5.00 |
| Probability of success | 72% |
| Short delta | .33 |

| Sell APR Call vertical | -70 / +75 |
| Credit $1.10 | Spread $5.00 |
| Probability of success | 75% |
| Short delta | .35 |

Let’s say that you want to generate monthly income by trading spreads or iron condors. You could get into a 2-wide spread iron condor on SPY or DIA for $.70 credit, with 60% probability of success. And you plan to exit when the trade has reached 80% of its profit potential (exit prior to expiration).
Net profit on a single trade would be $46.

Max profit |
$70 | |
| Commissions | $12 | 8 * $1.50 |
| Profit at expiration | $58 | |
| Profit at 80% | $46 | Approx. |
| Margin | $130 | $200 – $70 |
So, if you want to make $1,000 / month multiply the number of contracts by: 22
|
Max profit |
$1540 | |
| Commissions | $264 | 176 * $1.50 |
| Profit at expiration | $1276 | |
| Profit at 80% | $1012 | Approx. |
| Margin | $2860 | $4400 – $1540 |
