Weekly update 8/28/2026
Current beta weighted risk is 6.9 against the SPX. Overall theta on S&P futures is 76.2. SPX beta weighted risk ~$53,206. All else being equal, this represents $2,286 every 30 days due to theta decay ~4.2% monthly. Beta weighted portfolio value is over 2x the futures balance ($23,674). The attached graph shows the current stress test with losses beginning at /MES price of $6,275 and $8,946 by 10/1/2026. Created a LEAPS position in The Trade Desk (TTD), this former darling of the market has dropped into what I consider to be the appropriate price for an entry trading at about 10x the owner earnings. The company maintains a long history of double digit growth in the key areas of book value + dividends, earnings, operating cash flows, and revenues. I expect this company to be fairly valued at just over $27/share. My exposure is based on the sale of three LEAPS puts @ 15/share with a 839 DTE expiration and two long calls at the same expiration @ 12.5 strikes. Total max loss is $4,500 representing 6.4% of the total account liquidity. Readers can see the major positions held by my account in the classroom section under trading journal.

Interesting with TTD

Current beta weighted risk is 5.8 against the SPX. Overall theta on S&P futures is 73.2. SPX beta weighted risk ~$45,157. All else being equal, this represents $2,196 every 30 days due to theta decay ~4.9% monthly. Beta weighted portfolio value is approximately 1.5x the futures balance ($27,332). The attached graph shows the current stress test with losses beginning at /MES price of $6,024 and $8,789 by 9/19/2026. Opened a position in Zoetis (ZTS) as this company appears to be underpriced in my opinion. Also trimmed exposure to Schwab (SCHW) by removing the short leg of that synthetic due to the recent run up, current exposure to Schwab is $1,345. Missed the increased return from the recent Paycom (PAYC) jump in price, kicking myself for not holding a position there.

What is the thesis behind Zoetis?

Current beta weighted risk is 4.7 against the SPX. Overall theta on S&P futures is 67.82. SPX beta weighted risk ~$35,198. All else being equal, this represents $2,035 every 30 days due to theta decay ~5.8% monthly. Beta weighted portfolio value is approximately 2x the futures balance ($17,539). The attached graph shows the current stress test with losses beginning at /MES price of $6,043 and $8,490 by 8/22/2026. Approximately 2.6% of the portfolio is long micro oil futures as a hedge against Iran war escalation through /MCL futures options. Last week's position was adjusted to reflect the drop in oil futures this week when it appeared that the Iran war would stabilize again. Readers can see the major positions held by my account in the classroom section under trading journal. Annual update: after one full year of tracking since July of 2025, account value growth (loss) not including deposited funds is $13,518 for an annualized return of just over 31%.

@Greggory Miller Very nice! That is including all the cost right? I always think when I see other products than stocks that maybe it is very costly with fees to hedge etc. But looks like you have that into account

@Greggory Miller Got it! 1-2 years are too short to judge then if it is very volatile. Will be interesting to see after 5 years for example 🙂

Current beta weighted risk is 5.4 against the SPX. Overall theta on S&P futures is 102.3. SPX beta weighted risk ~$40,024. All else being equal, this represents $3,069 every 30 days due to theta decay ~7.7% monthly. Beta weighted portfolio value is over 2x the futures value ($17,479). The attached graph shows the current stress test with losses beginning at /ES price of $6,142 and $8,765 by 8/22/2026. Approximately 1.6% of the portfolio is long micro oil futures as a hedge against Iran war escalation through /MCL futures options. Readers can see the major positions held by my account in the classroom section under trading journal. Removed some of the risk on /ES futures by purchasing an offsetting option for the open leg for three of the back ratios on the put side. All three purchases locked in profits as enough time decay has occurred to allow their purchase to be financed by the original trade.

If you were to give me an update with less technical terms how you think it is going for you so far over all, I would be very interested to hear that 🙂
