Current BLD snapshot
As of May 15, 2026, spot at $403.11, ATM IV 21.40%, IV rank 2.27%, expected move 6.14%. The iron condor on BLD below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this iron condor structure on BLD specifically: BLD IV at 21.40% is on the cheap side of its 1-year range, which means a premium-selling BLD iron condor collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 6.14% (roughly $24.73 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BLD expiries trade a higher absolute premium for lower per-day decay. Position sizing on BLD should anchor to the underlying notional of $403.11 per share and to the trader's directional view on BLD stock.
BLD iron condor setup
The BLD iron condor below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BLD near $403.11, the first option leg uses a $420.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BLD chain at a 34-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 BLD shares for the stock leg in covered calls and collars).

| Sell 1 | Call | $420.00 | $3.65 |
| Buy 1 | Call | $440.00 | $1.13 |
| Sell 1 | Put | $380.00 | $2.44 |

BLD thesis for this iron condor
The market-implied 1-standard-deviation range for BLD extends from approximately $378.38 on the downside to $427.84 on the upside. A BLD iron condor is a delta-neutral premium-collection structure that pays off when BLD stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current BLD IV rank near 2.27% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on BLD at 21.40%. As a Industrials name, BLD options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BLD-specific events.
BLD iron condor positions are structurally neutral / range-bound; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. BLD positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BLD alongside the broader basket even when BLD-specific fundamentals are unchanged. Short-premium structures like a iron condor on BLD carry tail risk when realized volatility exceeds the implied move; review historical BLD earnings reactions and macro stress periods before sizing. Always rebuild the position from current BLD chain quotes before placing a trade.
