Selling cash-secured puts on QQQ

Selling a put transfers the downside between $723 and zero to you, and you are paid $9.24 per share for taking it. "Cash-secured" simply means you hold the $72,300 required to buy the shares instead of leaning on margin. Same position, honest denominator.

At October 30, 2026: above $723 the put expires worthless and you keep $924 — that is the maximum this trade can make, $924. Below it you're assigned 100 shares at $723, with an effective cost basis of $713.76 once the credit is applied. That is 4.1% below where QQQ trades today.

The engine puts the probability of keeping the full credit at 75% on QQQ at $744.5 with 20% ATM implied vol on the Oct 30 expiry. High win rate, capped payoff, uncapped-to-zero loss — the risk profile of every short-premium trade. It is not free money; it is a rent cheque for underwriting someone else's insurance.

Max loss is $71,376 — the strike, less the credit, times 100, if QQQ goes to zero. That number is not theoretical on single names; it is simply unlikely. Size the position against that figure, not against the premium.

Assignment is not the loss — being assigned at $723 when QQQ is at $578.4 is. If you are running the wheel, that is the moment the plan is tested: you own shares at a basis of $713.76 and the market disagrees.

Liquidity is a risk, not a convenience. The moment you most want out of a short-premium position is the moment the spread is widest, and the exit price you modelled at mid will not be available.

You are paid more than on SPY for a reason: the concentration. Selling QQQ premium through an October or a January earnings cluster is selling correlated single-name event risk in one ticket, and the diversification an index normally provides is exactly what is missing that fortnight. Check whose print lands inside your expiry before you take the credit.

QQQ's Oct 30 strikes are $3 apart near the money (0.40% of spot). Workable granularity — though every rung you move a strike is a material change to the payoff, not a rounding. 71k contracts of open interest on Oct 30 is workable around the money and thin in the wings — width costs more here than the ladder suggests. 50 strikes on that expiry — 94% of the board — carry prints that agree with their own implied volatility and hold up across the ladder, and those are the strikes priced here. Institutional depth at every strike; the only real cost is that the strike ladder is coarse relative to spot.

Skew is ordinary — the 25-delta put implies 4.0% more vol than the 25-delta call, about what an equity surface looks like when nothing unusual is being priced. Neither side of the chain is being singled out, which is the condition under which a symmetric structure like a condor is actually symmetric. The term structure is flat inside 1.5% between the two captured expiries, so there is no calendar edge to harvest and no event visibly priced into one month over the other.

At 20% ATM implied vol, the Oct 30 options are pricing a one-standard-deviation move of $43.91 over 33 days — roughly −5.9% to +5.9%, or $700.59 to $788.41. A short-premium structure here is a bet that 5.9% over 33 days is more than QQQ will actually use. That is the thesis, stated honestly.

The QQQ-specific failure mode: Treating QQQ as a diversified index in the two weeks when four of its top holdings report. It behaves like a basket of correlated singles.
