What is a butterfly on ROCK?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
Current ROCK snapshot
As of June 30, 2026, spot at $44.80, ATM IV 48.20%, IV rank 6.19%, expected move 13.82%. The butterfly on ROCK 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 17-day expiry.
Why this butterfly structure on ROCK specifically: ROCK IV at 48.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a ROCK butterfly, with a market-implied 1-standard-deviation move of approximately 13.82% (roughly $6.19 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ROCK expiries trade a higher absolute premium for lower per-day decay. Position sizing on ROCK should anchor to the underlying notional of $44.80 per share and to the trader's directional view on ROCK stock.
ROCK butterfly setup
The ROCK butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ROCK near $44.80, the first option leg uses a $42.56 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ROCK chain at a 17-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 ROCK shares for the stock leg in covered calls and collars).

ROCK thesis for this butterfly
The market-implied 1-standard-deviation range for ROCK extends from approximately $38.61 on the downside to $50.99 on the upside. A ROCK long call butterfly is a pinning play: it pays maximum at the middle strike if ROCK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ROCK IV rank near 6.19% 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 ROCK at 48.20%. As a Industrials name, ROCK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ROCK-specific events.
ROCK butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. ROCK positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ROCK alongside the broader basket even when ROCK-specific fundamentals are unchanged. Always rebuild the position from current ROCK chain quotes before placing a trade.
