NVDA bull put spread: credit, risk, strikes

You are still selling downside — just not all of it. The long $210 put cuts the tail off below that level, which is why this needs $375 of buying power instead of the $21,500 a cash-secured put would tie up.

Above $215 at October 30, 2026, both puts expire worthless and you keep the full $125. Below $210, you lose the maximum $375. Breakeven is $213.75.

Return on risk is 33% for 33 days — 369% annualized. That headline is the reason people prefer spreads to cash-secured puts, and the reason spreads blow up accounts: the same capital supports several times the notional risk.

The risk is leverage, not the structure. $375 per spread is small; the temptation to sell ten of them because the buying power allows it is how a 69%-win-rate trade produces a losing year.

Early assignment on the short leg leaves you long 100 shares plus a long put — a synthetic call, not a disaster, but a position you did not choose and one that requires $21,500 of cash on Monday.

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.

The premium is enormous and so is the reason for it. Selling puts on NVDA outside an earnings window is a defensible short-vol trade; selling them through one is underwriting a distribution whose tails you have watched print in real time. If you are running the wheel here, the assignment is not the hypothetical — it is the base case at least once a year, and your basis needs to survive it.

NVDA's Oct 30 strikes are $5 apart near the money (2.22% of spot). On a ladder that wide, "pick the 0.30 delta strike" resolves to whichever rung happens to be closest — sometimes not close at all. 65k 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. 21 strikes on that expiry — 100% 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. Enormous volume and open interest; complex structures fill near mid even in size, including through the print.

Skew is ordinary — the 25-delta put implies 2.5% 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 in contango: the back month implies 5.0% more vol than the front. Calm now, uncertainty later — which rewards selling the front month and makes the back month an expensive thing to own outright.

At 32% ATM implied vol, the Oct 30 options are pricing a one-standard-deviation move of $21.67 over 33 days — roughly −9.6% to +9.6%, or $203.4 to $246.74. A short-premium structure here is a bet that 9.6% over 33 days is more than NVDA will actually use. That is the thesis, stated honestly.

The NVDA-specific failure mode: Sizing a short-premium NVDA position off the credit rather than off the gap. The credit is large because the gap is large.
