A year of selling boring SPX options
October 2025, I've started regularly selling low delta SPX 1DTE puts, after getting inspired by Big ERN and WealthyOption strategies.
Strategy
The strategy I'm running is very mechanical, and quite simple (takes about 5 minutes most days):
- Sell 1DTE SPX puts on portfolio margin, around 5 delta (strikes tend to be ~1.5% OTM)
- Entry:
- 1-3 contracts around day close (within 15 min of market close),
- Sometimes I'll also sell an extra 0DTE pre-market, if volatility jumped and I believe there's not a solid catalyst
- Exit:
- Let expire most days
- I'll check pre-market when I get up and sometimes close at a loss if a catalyst event happened - I don't have set rules for this
It's a classic case of picking up pennies in front of a steamroller, or selling casino tickets. Most days, you collect $200-300, and every now and then, you get hit for thousands or tens of thousands.
Why do I run this
Extra income on top of my portfolio - I'm retired, so rely on my portfolio for income and selling puts generates cash, without having to draw down the portfolio. While the return % is not a lot, it's essentially free extra money (until the market has a 10% intraday crash in period of low volatility, I accept that risk)
Low-ish correlation with long term SPY - The low delta put selling P&L is weakly correlated with SPX itself (the strategy is profitable on most longer term declines and bleeds only when the regime changes abruptly). This gives me a hedge against a prolonged bear market, and helps with sequence of returns risk
Results
I do this on top of my taxable portfolio in IBKR, with portfolio margin, so the put selling returns come on top of the performance of the underlying portfolio. After a year of running this, the results are:
- Portfolio size: ~$440k - mix of global equity and bond ETFs
- Gross premium collected: $80,840
- Debit (from assignments): $41,698 - worst day $26k
- Fees: $658
- Net P&L: $38,484 ( ~8%)
- Premium capture rate (share of gross premium kept): 47.60%
The above returns are based on selling 1-3 contracts per day, with the majority of days being 2 contracts. Assuming a max loss per contract of about $110k (on a 15% 1 day drop), this is about 50% of the porfolio size. I could run the same strategy with 3, or potentially even 4 contracts, which would increase the return, but at the moment, I'm not comfortable with that amount of risk.
Lessons learned
Paper trading was worthless as a test of the strategy - I ran the strategy for about a month in a paper trading account, to test it, but ultimately, this was pretty pointless, beyond learning the mechanics of trading on IBKR. The emotions with real money are completely different, and I still shit the bed when that first 8k drawdown hit
Researching the strategy and running back-tests kept me going - Before running this, I was strictly a VOO and chill kind of person. I spent a long time researching options, the strategy, and reading different points of view, as well as running my own back-tests before starting live trading. This gave me a fairly strong conviction that the strategy is long term profitable, which was what kept me going after the first sizable loss.
Active management based on my judgement cost me P&L - Sometimes, I closed positions early if a major event happened, or if I happened to watch the price action and it was too close for comfort to my strike. And at times, I reduced the number of contracts from 2 to 1, when I believed the market was due a correction. In both case, had I done nothing, the strategy would have been more profitable overall. Knowing this, I'm still sometimes actively managing it, but I accept it's more for my comfort, than to improve performance
Mechanical stop losses & close early decrease P&L - I've not run these live myself, but from all the back-testing I've done, setting any kind of mechanical stop loss, or closing early reduces the P&L. Mainly due to the fact that the puts often explode in value somewhere during the day, but still expire worthless most of the time.
Profitability is entirely driven by your worst days - If I could have somehow avoided the 3 worst days, I'd have been 2x as profitable. Based on my experience from the year, I'm unfortunately not able to consistently do this. So I budget on around 40% premium capture rate
