IWM iron condor, priced on the real chain

Four legs, one idea: you are selling the market's estimate of how far IWM can travel. The short strikes ($275 / $305) define the range you're renting out; the long wings ($270 / $310) cap what a violent move can cost you.

Both spreads cannot lose. IWM finishes on one side of the market, so at most one vertical goes in the money — which is why max loss is the width of ONE spread minus the credit, $379, not double it. Max profit is the $121 credit, earned by doing nothing.

Breakevens land at $273.79 and $306.21. Outside that band the position loses; between it, it wins. That band is 11.1% wide relative to spot, against 19% implied vol over 27 days.

Return on risk is $121 against $379 — roughly 32% if it works. You need a high hit rate to justify that ratio, which is exactly what the 67% probability is telling you.

The risk shape is a plateau with two cliffs. Anywhere between $273.79 and $306.21 you make money; past the long wings you lose a fixed $379. Between short and long strike the P/L slides linearly — that is where most condors are actually managed, not at expiry.

The killer is a trend, not a spike. A slow grind through the short call over three weeks costs the same as a gap and gives you more chances to talk yourself out of closing.

Liquidity is a risk, not a convenience. The moment you most want out of a short-premium position is the moment the spread is widest, and the exit price you modelled at mid will not be available.

The richest index premium on this list, and the one that most reliably pays for itself — small-cap implied vol has run a wider gap over realized than SPY's for years. The catch is trend: IWM does not chop, it goes, and a short strike that looked comfortable at 0.16 delta gets run over in a week when the rate narrative flips.

IWM's Aug 28 strikes are $1 apart near the money (0.34% of spot). At that granularity the strike ladder stops being a constraint on the trade and starts being a genuine choice. 72k 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. 55 strikes on that expiry — 47% 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 enough for four legs at retail size; the wings thin out faster than on SPY, so cap width at what the book supports.

Skew is ordinary — the 25-delta put implies 4.9% more vol than the 25-delta call, about what an equity surface looks like when nothing unusual is being priced. Neither side of the chain is being singled out, which is the condition under which a symmetric structure like a condor is actually symmetric. 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 19% ATM implied vol, the Aug 28 options are pricing a one-standard-deviation move of $15.01 over 27 days — roughly −5.2% to +5.2%, or $276.19 to $306.21. A short-premium structure here is a bet that 5.2% over 27 days is more than IWM will actually use. That is the thesis, stated honestly.

What actually goes wrong here, as opposed to in general: Selling the wings because the index label implies mean reversion. IWM's realized distribution has fatter shoulders than SPY's at the same implied vol.
