Buying PLTR puts: hedge math and breakevens

A long put is the right to sell 100 shares at $123 until August 28, 2026. Max loss is the $935 premium; max profit is $11,365, reached only if PLTR goes to zero.

Below $113.65 the position is in profit at expiry, gaining one-for-one with each dollar the stock falls. Above $123 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 $123 at the cost of 7.6% of position value — an annualized drag of 102.7% 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 27-day window entirely.

If you are hedging, be clear about what you are insuring. One put covers 100 shares — $12,306 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 Aug 28 strikes are $1 apart near the money (0.81% of spot). Enough rungs to express a view, few enough that each one moves the economics visibly. 30k contracts of open interest on Aug 28 is workable around the money and thin in the wings — width costs more here than the ladder suggests. 49 strikes on that expiry — 50% 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.

Skew is inverted: the 25-delta CALL implies 2.5% more vol than the put. That is the market pricing upside risk above downside risk — a squeeze, a takeover rumour, or a crowded short. Owning upside on an inverted skew means paying the expensive side of the surface, which is worth knowing before you buy the call. The term structure is backwardated — Aug 28 implies 8.3% MORE vol than the following month. That is the signature of a dated event inside the front month, and it is the strongest argument for picking the expiry that sits behind it.

At 70% ATM implied vol, the Aug 28 options are pricing a one-standard-deviation move of $23.41 over 27 days — roughly −19.0% to +19.0%, or $99.65 to $146.47. 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.
