AMZN strangle: the breakevens nobody quotes

Both legs are pure extrinsic value, so the strangle is a leveraged bet that AMZN travels further than 40% implied vol says it will over 33 days. Between the strikes at expiry, both expire worthless and you lose the entire $965.

The payoff is a valley: flat max loss between $235 and $275, then linear gains once past the breakevens at $225.35 and $284.65. Max profit is unlimited.

Compared with the straddle at the same expiry, you pay less and need more. That is not a free improvement — it is a different bet, with a lower probability of profit (33% here) and a bigger multiple when it works.

Gamma is lower than a straddle's while the stock sits between the strikes, so the position responds sluggishly to the first part of a move and then accelerates. Traders consistently underestimate that lag.

Double theta with no offset: two long options bleeding simultaneously. Over 33 days that decay is the single largest determinant of the outcome if the move is late.

Post-event IV crush hits both legs at once. A strangle bought into earnings can lose money on a move in the right direction if the vol collapse is bigger than the delta gain.

Implied vol can fall while the stock moves. Long-vol structures lose money in that scenario despite the thesis technically working, which is the single most common way these trades disappoint.

The term structure into an Amazon print is one of the steepest on this list, which makes the calendar the natural expression: sell the expensive front month, own the back. Straddles bought inside the front week are paying the peak of that curve.

AMZN's Oct 30 strikes are $5 apart near the money (2.00% 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. 146k contracts of open interest on Oct 30 is deep enough that multi-leg orders fill near mid at retail size. 29 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. Deep at every strike; the far-dated back month a calendar needs is liquid enough to leg if you must.

The surface is close to flat: only 0.2% 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 backwardated — Oct 30 implies 2.0% 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 40% ATM implied vol, the Oct 30 options are pricing a one-standard-deviation move of $30.04 over 33 days — roughly −12.0% to +12.0%, or $219.63 to $279.71. That is the number the long-vol trade above has to beat — not match. Breakevens sit outside it by construction, because you paid the spread as well as the vol.

What actually goes wrong here, as opposed to in general: Buying the holiday-quarter straddle because the narrative is loud. That print's implied move is usually the year's largest and usually adequate.
