What is a butterfly on CASS?
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 CASS snapshot
As of May 15, 2026, spot at $45.36, ATM IV 46.20%, IV rank 17.22%, expected move 13.25%. The butterfly on CASS 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 butterfly structure on CASS specifically: CASS IV at 46.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a CASS butterfly, with a market-implied 1-standard-deviation move of approximately 13.25% (roughly $6.01 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 CASS expiries trade a higher absolute premium for lower per-day decay. Position sizing on CASS should anchor to the underlying notional of $45.36 per share and to the trader's directional view on CASS stock.
CASS butterfly setup
The CASS 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 CASS near $45.36, the first option leg uses a $43.09 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CASS 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 CASS shares for the stock leg in covered calls and collars).

CASS thesis for this butterfly
The market-implied 1-standard-deviation range for CASS extends from approximately $39.35 on the downside to $51.37 on the upside. A CASS long call butterfly is a pinning play: it pays maximum at the middle strike if CASS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current CASS IV rank near 17.22% 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 CASS at 46.20%. As a Industrials name, CASS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CASS-specific events.
CASS 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. CASS positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CASS alongside the broader basket even when CASS-specific fundamentals are unchanged. Always rebuild the position from current CASS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on CASS?
- A butterfly on CASS is the butterfly strategy applied to CASS (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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.

- How are CASS butterfly max profit and max loss calculated?
