Buying NVDA puts: hedge math and breakevens

A long put is the right to sell 100 shares at $225 until October 30, 2026. Max loss is the $855 premium; max profit is $21,645, reached only if NVDA goes to zero.

Below $216.45 the position is in profit at expiry, gaining one-for-one with each dollar the stock falls. Above $225 it expires worthless — which is the good outcome if you own the shares.

Puts carry a structural headwind: skew. Downside strikes on NVDA trade at higher implied vol than equivalent upside strikes because everybody wants the same protection at the same time. You are buying the expensive wing, always.

As a hedge on 100 shares, this put caps the loss below $225 at the cost of 3.8% of position value — an annualized drag of 42.0% if you run it continuously. That is the honest price of permanent protection, and it is why most people don't.

The modal outcome for a bought put is expiring worthless. NVDA above $225 at October 30, 2026 costs the full $855, and stocks drift up more often than down.

If you are hedging, be clear about what you are insuring. One put covers 100 shares — $22,507 of NVDA. A hedge that covers a quarter of your position is a quarter of a hedge.

The ceiling on a spread is a real cost, not a theoretical one. It is paid exactly in the scenarios where your thesis worked best, which is when it hurts most to notice.

The one name on this list where a call spread's capped upside genuinely costs you money often enough to notice. NVDA's post-earnings moves have repeatedly cleared the short strike of any sensibly-priced spread, so if your thesis is a re-rating rather than a drift, the spread is the wrong instrument and you should pay for the tail.

NVDA's Oct 30 strikes are $5 apart near the money (2.22% of spot). That is a coarse ladder: one rung is a large fraction of the implied move, so precision on the short strike is an illusion. 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. Nothing on the surface argues strongly for one direction of structure over the other. 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. That band is the free part of the move. Anything your structure needs beyond it is the part you have to be right about.

The specific way people lose money on NVDA: Sizing a short-premium NVDA position off the credit rather than off the gap. The credit is large because the gap is large.
