Buying GOOGL puts: hedge math and breakevens

A long put is the right to sell 100 shares at $355 until August 28, 2026. Max loss is the $1,070 premium; max profit is $34,430, reached only if GOOGL goes to zero.

Below $344.3 the position is in profit at expiry, gaining one-for-one with each dollar the stock falls. Above $355 it expires worthless — which is the good outcome if you own the shares.

Puts carry a structural headwind: skew. Downside strikes on GOOGL 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 $355 at the cost of 3.0% of position value — an annualized drag of 40.6% 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. GOOGL above $355 at August 28, 2026 costs the full $1,070, and stocks drift up more often than down.

If you are hedging, be clear about what you are insuring. One put covers 100 shares — $35,613 of GOOGL. A hedge that covers a quarter of your position is a quarter of a hedge.

Implied vol works against a debit buyer in both directions: pay too much for it at entry and the position needs a bigger move; watch it collapse after an event and the position loses even when the direction was right.

The one mega-cap where regulatory headlines can reprice the stock independently of the fundamentals, and that risk is not concentrated on an earnings date. A directional structure here should be dated on the legal calendar as much as the reporting one, which is an argument for longer expiries than the default.

GOOGL's Aug 28 strikes are $5 apart near the money (1.40% 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. 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. 28 strikes on that expiry — 45% 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. Tight and deep; a fine strike ladder makes precise strike selection genuinely possible.

Skew is inverted: the 25-delta CALL implies 2.0% 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 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 33% ATM implied vol, the Aug 28 options are pricing a one-standard-deviation move of $31.76 over 27 days — roughly −8.9% to +8.9%, or $324.37 to $387.89. A directional structure whose profit zone begins inside that band is expressing a view the market has already priced.

The GOOGL-specific failure mode: Writing calls at a delta borrowed from a higher-vol name. The same 0.30 delta buys far less premium here, and the assignment odds are identical.
