This case study analyzes and compares the credit spread option trading strategy of 1, 2, 3, 4, 5, 7 and 10 point credit spreads on the SPY. The SPY is an ETF that tracks at 1/10th the value of the S&P 500 index. We make the case that the 3 point credit spread is optimum and provides an excellent risk-adjusted return, minimizes the commission hit, it gives us flexibility to make adjustments when needed if the credit spread “get’s under pressure”, and it keeps the required maintenance level low enough to allow investors with different account sizes to participate in this option trading system.

Here are the assumptions used when making our calculations on this option trading system:

1) Commission = $1/options contract or $2/ credit spread. (we show additional commission rates in the spread sheet summary below)

2) $5000 of cash is available to open the spreads

3) The trade stays out-of-the-money (OTM) and profitable, and we let the spread expire worthless, which is 100% profitable for us, the seller. Thus, we only pay commission to open the credit spreads and we call this “one-way” commissions. (in contrast to round-trip commissions where we pay to open and close the trades)

4) All spreads have 31 days until expiration

5) We simplify the number of spreads that we can open by dividing the available $5000 of cash by the required maintenance.

Below is the SPY Aug 89/90 option trading strategy bull put spread which has the following characteristics:

1) It’s a 1 point credit spread (i.e. 1 point between the sell leg and the buy leg)

2) Required maintenance by the broker is $100 per option spread (1 point spread * $100/point)

3) 50 credit spreads can be opened ($5000/$100 of required maintenance per spread)

4) Premium collected is $15 credit x 50 spreads = $750

5) Risk capital is $5000 in maintenance – $750 of premium collected = $4250

6) One-way commission at $1/contract is 50 spreads x $2/spread = $100.

7) Commission as a % of premium collected is 100/750 = 13.3%

8) ROI after one-way commission is (750-100)/4250 = 15.3%

Below is the SPY Aug 88/90 option trading system bull put spread which has the following characteristics:

1) It’s a 2 point spread option (i.e. 2 points between the sell leg and the buy leg)

2) Required maintenance by the broker is $200 per spread (2 point spread * $100/point)

3) 25 credit spreads can be opened ($5000/$200 required maintenance per spread)

4) Premium collected is $25 credit x 25 spreads = $625

5) Risk capital is $5000 in maintenance – $625 of premium collected = $4375

6) One-way commission at $1/contract is 25 spreads x $2/spread = $50.

7) One-way Commission as a % of premium collected is 50/625 = 8%

8) Return for this option trading system after one-way commission is (625-50)/4375 = 13.1%

Below is the SPY Aug 87/90 option trading strategy bull put spread which has the following characteristics:

1) It’s a 3 point spread option

2) Required maintenance by the broker is $300 per spread option

3) 16 credit spreads can be opened ($5000/$300)

4) Premium collected is $35 credit x 16 spreads = $560

5) Risk capital is $5000 in maintenance – $560 of premium collected = $4440

6) One-way commission is 16 spreads x $2/spread = $32.

7) One-way commission as a % of premium collected is 32/560 = 5.7%

8) Return for this option trading strategy after one-way commission is (560 – 32)/4440 = 11.8%

Below is the SPY Aug 86/90 option trading system bull put spread which has the following characteristics:

1) It’s a 4 point spread

2) Required maintenance by the broker is $400 per credit spread

3) 12 credit spreads can be opened ($5000/$400)

4) Premium collected is $44 credit x 12 spreads = $528

5) Risk capital is $5000 in maintenance – $528 of premium collected = $4472

6) One-way commission is 12 spreads x $2/spread = $24.

7) One-way commission as a % of premium collected is 24/528 = 4.5%

8) Return for this option trading sytem after one-way commission is (528 – 24)/4472 = 11.2%

Below is the SPY Aug 85/90 option trading strategy bull put spread with the following characteristics:

1) It’s a 5 point spread

2) Required maintenance by the broker is $500 per spread

3) 10 credit spreads can be opened

4) Premium collected is $50 credit x 10 spreads = $500

5) Risk capital is $5000 in maintenance – $500 of premium collected = $4500

6) One-way commission is 10 spreads x $2/spread = $20

7) One-way commission as a % of premium collected is 20/500 = 4%

8) Return for this option trading strategy after one-way commission is (500 – 20)/4500 = 10.6%

Below is the SPY Aug 83/90 option trading system bull put spread with the following characteristics:

1) It’s a 7 point spread

2) Required maintenance by the broker is $700 per spread

3) 7 credit spreads can be opened ($5000/$700 required maintenance per spread)

4) Premium collected is $58 credit x 7 spreads = $406

5) Risk capital is $5000 in maintenance – $406 of premium collected = $4594

6) One-way commission is 7 spreads x $2/spread = $14

7) One-way commission as a % of premium collected is 14/406 = 3.4%

8) Return for this option trading system after commission is (406 – 14)/4594 = 8.5%

Below is the SPY Aug 80/90 option trading strategy bull put spread with the following characteristics:

1) It’s a 10 point spread

2) Required maintenance by the broker is $1000 per spread

3) 5 credit spreads can be opened

Conclusion: From the analysis above, we like the 3 point option trading strategy spread where it gives us an excellent return, minimizes the commission hit, gives us flexibility to make adjustments when needed if it “gets under pressure”, and the required maintenance is low enough to allow investors with different account sizes to participate in the trade. When we say that we need “flexibility” to make adjustments with this option trading system, when the spread gets under pressure from a fast moving underlying index (the SPY in this case) we implement the “stay ahead of the wave” strategy by “clicking-down” our strike price to move further away from the underlying index and we open more spreads to bring in more premium. If we use the 3 point spread we have the flexibility to “click-down” 3 times if needed. (in this case we are talking about the bottom, bull put spread) For example, let’s say we have a SPY 90/93 bull put spread and 10 days after we open this spread the SPY sells-off putting our 90/93 bull put spread “under pressure”. In this situation, we would not yet close-out the SPY 90/93 spread but we would watch it closely, and in parallel we would “stay ahead of the wave” and click-down a strike to the SPY 89/92 bull put spread (in the same month) and open some to continue to bring in premium. And if we need to click-down again, we have the flexibility to click-down one more time to the SPY 88/91 bull put spread to allow us to keep bringing in premium. If we need to click down even further, we won’t be able to open the SPY 87/90 bull put spread until we close-out the original SPY 90/93 bull put spread because the 90 strike overlaps and will cancel each other out; however, this is ok because if the underlying SPY is dropping this fast, and just by the fact that we’ve already clicked down 3 times, we probably will need to close out the original SPY 90/93 anyway to cut our losses and to minimize any further downside. With this said, and especially for bull put spreads, we would not engage in the “stay ahead of the wave” strategy unless the “market timing” indicators were giving us the green light that the economy and the market are “healthy” and therefore it’s ok to keep clicking down and bringing in premium.
