Buying PLTR puts: hedge math and breakevens

A long put is the right to sell 100 shares at $190 until October 30, 2026. Max loss is the $1,040 premium; max profit is $17,960, reached only if PLTR goes to zero.

Below $179.6 the position is in profit at expiry, gaining one-for-one with each dollar the stock falls. Above $190 it expires worthless — which is the good outcome if you own the shares.

Puts carry a structural headwind: skew. Downside strikes on PLTR 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 $190 at the cost of 5.5% of position value — an annualized drag of 60.6% if you run it continuously. That is the honest price of permanent protection, and it is why most people don't.

Timing risk is worse than for calls: crashes are fast and rare, so a put's payoff is concentrated into a few days that may fall outside your 33-day window entirely.

If you are hedging, be clear about what you are insuring. One put covers 100 shares — $18,967 of PLTR. 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.

Palantir's moves come from contract announcements and flows more than from the quarterly numbers, and those do not appear on any calendar you can date an expiry against. That argues for longer-dated debit structures over weeklies, and against any construction that needs the move by a specific Friday.

PLTR's Oct 30 strikes are $2.5 apart near the money (1.32% of spot). Coarse enough that the strike you want frequently does not exist, and the nearest rung is a different trade. 22k 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. 38 strikes on that expiry — 95% 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. Retail-deep with a fine strike ladder and real weekly open interest; one of the few high-vol names where four legs fill cleanly.

The surface is close to flat: only 0.7% between the 25-delta put and the 25-delta call. With so little skew, the wings on either side cost about the same in vol terms — unusual, and worth exploiting if your view is one-sided. The term structure is in contango: the back month implies 10.3% 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 48% ATM implied vol, the Oct 30 options are pricing a one-standard-deviation move of $27.37 over 33 days — roughly −14.4% to +14.4%, or $162.3 to $217.04. Compare that with where the short strike of the structure above sits. A target inside the implied move is one the market already thinks is likely; a target outside it is the one you are actually being paid for.

The PLTR-specific failure mode: Running the wheel on a position size that assumes assignment is unlikely. On this name assignment is the plan, and the drawdown after it is the part people are unprepared for.
