AMZN strangle: the breakevens nobody quotes

Both legs are pure extrinsic value, so the strangle is a leveraged bet that AMZN travels further than 33% implied vol says it will over 27 days. Between the strikes at expiry, both expire worthless and you lose the entire $672.

The payoff is a valley: flat max loss between $255 and $290, then linear gains once past the breakevens at $248.28 and $296.72. 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 (32% 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 27 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 Aug 28 strikes are $5 apart near the money (1.84% 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. 16k 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. 23 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. Deep at every strike; the far-dated back month a calendar needs is liquid enough to leg if you must.

Skew is inverted: the 25-delta CALL implies 1.3% 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 $24.05 over 27 days — roughly −8.9% to +8.9%, or $247.53 to $295.63. 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.
