Current BLDR snapshot
As of June 30, 2026, spot at $89.59, ATM IV 54.40%, IV rank 38.25%, expected move 15.60%. The bull call spread on BLDR 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 52-day expiry.
Why this bull call spread structure on BLDR specifically: BLDR IV at 54.40% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 15.60% (roughly $13.97 on the underlying). The 52-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BLDR expiries trade a higher absolute premium for lower per-day decay. Position sizing on BLDR should anchor to the underlying notional of $89.59 per share and to the trader's directional view on BLDR stock.
BLDR bull call spread setup
The BLDR bull call spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BLDR near $89.59, the first option leg uses a $90.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BLDR chain at a 52-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 BLDR shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $90.00 | $7.65 |

BLDR thesis for this bull call spread
The market-implied 1-standard-deviation range for BLDR extends from approximately $75.62 on the downside to $103.56 on the upside. A BLDR bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on BLDR, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current BLDR IV rank near 38.25% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on BLDR should anchor more to the directional view and the expected-move geometry. As a Industrials name, BLDR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BLDR-specific events.
BLDR bull call spread positions are structurally moderately bullish; 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. BLDR positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BLDR alongside the broader basket even when BLDR-specific fundamentals are unchanged. Long-premium structures like a bull call spread on BLDR are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current BLDR chain quotes before placing a trade.
